1-4 Responsibility  
These machines are constructed for maximum operator safety when used under standard  
operating conditions and when recommended instructions are followed in the maintenance  
and operation of the machine.  
All personnel engaged in the use of the machine should become familiar with its operation as  
described in this manual.  
Proper operation of the machine promotes safety for the operator and all workers in its  
vicinity.  
Each individual must take responsibility for observing the prescribed safety rules as outlined.  
All warning and danger signs must be observed and obeyed. All actual or potential danger  
areas must be reported to your immediate supervisor.  
General Responsibility  
No mater who you are, safety is important. Owners, operators and maintenance personnel  
must realize that every day, safety is a vital part of their jobs.  
If your main concern is loss of productivity, remember that production is always affected in a  
negative way following an accident. The following are some of the ways that accidents can  
affect your production:  
Loss of a skilled operator (temporarily or permanently)  
Breakdown of shop morale  
Costly damage to equipment  
Downtime  
An effective safety program is responsible and economically sound.  
Organize a safety committee or group, and hold regular meetings. Promote this group from  
the management level. Through this group, the safety program can be continually reviewed,  
maintained, and improved. Keep minutes or a record of the meetings.  
Hold daily equipment inspections in addition to regular maintenance checks. You will keep  
your equipment safe for production and exhibit your commitment to safety.  
Please read and use this manual as a guide to equipment safety. This manual contains safety  
warnings throughout, specific to each function and point of operation.  
Operator Responsibility  
15, 30, & 60 cfm Compact Dryers

Download from Www.Somanuals.com. All Manuals Search And Download.  
 
The operator’s responsibility does not end with efficient production. The operator usually has  
the most daily contact with the equipment and intimately knows its capabilities and  
limitations.  
Plant and personnel safety is sometimes forgotten in the desire to meet incentive rates, or  
through a casual attitude toward machinery formed over a period of months or years. Your  
employer probably has established a set of safety rules in your workplace. Those rules, this  
manual, or any other safety information will not keep you from being injured while operating  
your equipment.  
Learn and always use safe operation. Cooperate with co-workers to promote safe practices.  
Immediately report any potentially dangerous situation to your supervisor or appropriate  
person.  
REMEMBER:  
NEVER place your hands or any part of your body in any dangerous location.  
NEVER operate, service, or adjust the dryer without appropriate training and first  
reading and understanding this manual.  
NEVER try to pull material out of the dryer with your hands while it is running!  
Before you start the dryer check the following:  
Remove all tools from the dryer;  
Be sure no objects (tools, nuts, bolts, clamps, bars) are laying in the  
hopper area;  
If your dryer has been inoperative or unattended, check all settings before starting the  
unit.  
At the beginning of your shift and after breaks, verify that the controls and other  
auxiliary equipment are functioning properly.  
Keep all safety guards in place and in good repair. NEVER attempt to bypass, modify,  
or remove safety guards. Such alteration is not only unsafe, but will void the warranty  
on your equipment.  
When changing control settings to perform a different mode of operation, be sure  
selector switches are correctly positioned. Locking selector switches should only be  
adjusted by authorized personnel and the keys removed after setting.  
Report the following occurrences IMMEDIATELY:  
unsafe operation or condition  
unusual dryer action  
leakage  
improper maintenance  
NEVER stand or sit where you could slip or stumble into the dryer  
while working on it.  
DO NOT wear loose clothing or jewelry, which can be caught while working on a  
dryer. In addition, cover or tie back long hair.  
Clean the dryer and surrounding area DAILY, and inspect the machine for loose,  
missing or broken parts.

Shut off power to the dryer when it is not in use. Turn the switch to the OFF position,  
or unplug it from the power source.  
Maintenance Responsibility  
Proper maintenance is essential to safety. If you are a maintenance worker, you must make  
safety a priority to effectively repair and maintain equipment.  
Before removing, adjusting, or replacing parts on a machine, remember to turn off all electric  
supplies and all accessory equipment at the machine, and disconnect and lockout electrical  
power. Attach warning tags to the disconnect switch.  
When you need to perform maintenance or repair work on a dryer above floor level, use a  
solid platform or a hydraulic elevator. If there is a permanently installed catwalk on your  
equipment, use it. The work platform should have secure footing and a place for tools and  
parts. DO NOT climb on dryers, machines, or work from ladders.  
If you need to repair a large component, use appropriate handling equipment. Before you use  
handling equipment (portable “A” frames, electric boom trucks, fork trucks, overhead cranes)  
be sure the load does not exceed the capacity of the handling equipment or cause it to become  
unstable.  
Carefully test the condition of lifting cables, chains, ropes, slings, and hooks before using  
them to lift a load.  
Be sure that all non-current carrying parts are correctly connected to earth ground with an  
electrical conductor that complies with current codes. Install in accordance with national and  
local codes.  
When you have completed the repair or maintenance procedure, check your work and remove  
your tools, rigging, and handling equipment.  
Do not restore power to the dryer until all persons are clear of the area. DO NOT start and  
run the dryer until you are sure all parts are functioning correctly.  
BEFORE you turn the dryer over to the operator for production, verify all dryer enclosure  
panels, guards and safety devices are in place and functioning properly.  
Reporting a Safety Defect  
If you believe that your equipment has a defect that could cause injury, you should  
immediately discontinue its use and inform the manufacturer.  
The principle factors that can result in injury are failure to follow proper operating procedures  
(i.e. lockout/tag out), or failure to maintain a clean and safe working environment.

Chapter 2: Functional Description  
2-1 Models Covered in This Manual  
This manual provides operation, installation, and maintenance instructions for 15, 30 and 60  
cfm dehumidifying dryers. Model numbers are listed on the serial tag. Make sure you know  
the model and serial number of your equipment before contacting the manufacturer for parts  
or service.  
Our dehumidifying mini dryers are designed to generate heated dehumidified air (at a very  
low dew point) at carefully controlled temperatures for use in plastic drying systems. The  
dryer circulates hot air through a column of plastic resin in the large drying hopper. The resin  
in the hopper is discharged through a slide gate in a “first in, first out” manner.  
2-2 General Description  
The Drying System  
Dehumidifying dryers are used to generate very low dew point air heated to a controlled  
temperature for drying plastic pellets and regrind.  
Our dryers force hot, dry air through resin in a drying hopper, where air picks up moisture  
from the material and draws it back to the dryer. In the dryer, a desiccant bed strips moisture  
from the air. The dried process air is then re-heated and delivered back into the drying  
hopper for more moisture removal.  
Portion of the low dew point process air is directed to the desiccant tank that is off process.  
This air is heated to approximately 450°F (232°C) before entering the bed that is in  
regeneration. The moisture is then forced from the desiccant before being exhausted into the  
atmosphere. A small amount of ambient air is introduced into the process return air filter to  
make up for the air lost during the bed regeneration. To compensate for the humidity content  
in the air, this dryer is supplied with the proper amount of desiccant.  
What is desiccant?  
Desiccant is a material that attracts and holds (absorbs) water from the air. The desiccant our  
dryers use is a synthetic crystalline metal aluminosilicate blended with a clay binder and  
formed into beads.  
The Process/Regeneration Cycle  
Our dryers have two desiccant beds. While one bed is on-line in the process air loop, the  
other is off-line, being regenerated.  
When a desiccant bed is on-line, it absorbs moisture from the process air. In time, the bed  
becomes saturated with moisture and needs to be regenerated. The dryer automatically  
redirects the process airflow to the second bed, and starts the regeneration cycle on the first  
bed.  
During regeneration, the dryer system heats the very low dew point air and forces it through  
the desiccant bed. The moisture driven off the bed bleeds to the atmosphere.

2-5 Safety Devices and Interlocks  
This section includes information on safety devices and procedures that are inherent to the  
Dryer. This manual is not intended to supersede or alter safety standards established by the  
user of this equipment. Instead, the material contained in this section is recommended to  
supplement these procedures in order to provide a safer working environment.  
At the completion of this section, the operator and maintenance personnel will be able to do  
the following:  
Identify and locate specific safety devices.  
Understand the proper use of the safety devices provided.  
Describe the function of the safety device.

Safety Circuit Standards  
Safety circuits used in industrial systems protect the operator and maintenance personnel  
from dangerous energy. They also provide a means of locking out or isolating the energy for  
servicing equipment.  
Various agencies have contributed to the establishment of safety standards that apply to the  
design and manufacture of automated equipment. The Occupational Safety and Health  
Administration (OSHA) and the Joint Industrial council (JIC) are just a few of the  
organizations that have joined with the plastics industry to develop safety standards.  
Every effort has been made to incorporate these standards into the design of the drying  
system; however, it is the responsibility of the personnel operating and maintaining the  
equipment to familiarize themselves with the safety procedures and the proper use of any  
safety devices.  
Fail Safe Operation  
If a safety device or circuit should fail, the design must be such that the failure causes a  
“Safe” condition. As an example, a safety switch must be a normally open switch. The switch  
must be held closed with the device it is to protect. If the switch fails, it will go to the open  
condition, tripping out the safety circuit.  
At no time should the safety device fail and allow the operation to continue. For  
example, if a safety switch is guarding a motor, and the safety switch fails, the motor should  
not be able to run.  
Safety Device Lock-Outs  
Some safety devices disconnect electrical energy from a circuit. The safety devices that are  
used on these dryers are primarily concerned with electrical power disconnection and the  
disabling of moving parts that may need to be accessed during the normal operation of the  
machine.  
Some of the safety devices utilize a manual activator. This is the method of initiating the  
safety lock out. This may be in the form of a plug, lever or a handle. Within this lockable  
handle, there may be a location for a padlock. Personnel servicing the equipment should  
place a padlock in the lockout handle.  
In addition to the safety devices listed above, these dryers are equipped with a line cord plug.  
This allows the operator or maintenance personnel to unplug the dryer from its power source  
and tag it out. The plug can then be tagged with any number of approved electrical lockout  
tags available at most electrical supply stores.  
WARNING! Always disconnect and lockout all electrical power and pneumatic (i.e. compressed air)  
sources prior to servicing or cleaning the dryer. Failure to do so may result in serious  
injury. No one but the person who installed the lockout may remove it.

contained in a cardboard box.  
1. Pry the crating away from the skid.  
Note: Remove the nails holding the box to the skid and lift the box  
off carefully; avoiding staples in the 1’ x 4’ wood supports.  
Cut the steel banding.  
2. Use a pry bar to remove the blocks securing the unit to the skid.  
3. Lift unit from sides. Use a pry bar if necessary to carefully remove the  
skid from the unit.  
4. Lower slowly.  
3-2 Rigging and Placing the Dryer  
Take care when rigging and placing the dryer. Figures 1, 2 and 3 on the following pages show  
a suggested safe rigging diagram. It lets you lift the dryer/hopper unit vertically for  
installation on the machine throat. Adjust chain lengths at the center sling bracket before you  
lift the unit. Your dryer has built-in lifting lugs.  
Caution!  
If you are mounting a machine-mount dryer with a magnet or transition adaptor on the  
machine throat, you must provide additional support to hold the dryer securely on the  
machine.  
Be aware that off-center static and dynamic hopper loading can occur with machine  
vibration. Again, provide additional support to hold the dryer securely on the machine.  
Use caution and observe safety rules when lifting and placing your dryer!

When using a hoist to move a machine mounted dryer, ALWAYS attach  
chains to the three (3) locations/lifting points on the unit! Moving the  
Dryer without the chains attached to all of the lifting points will cause the  
unit to become unstable and may cause damage to the Dryer and/or injury  
to personnel!  
3-3 Electrical Connections  
When making electrical connections to your dryer, ensure that you take into consideration  
and make arrangements for the following:  
A qualified electrician should make all electrical connections.  
Fulfill all national, state, and local safety and electrical code requirements.  
The serial tag lists voltage, phase, and amp draw information:  
Line voltage must be within plus or minus ten percent (±10%) of the  
voltage listed on the serial tag, or damage may occur. Phase imbalance  
must be less than two percent (2%).  
Connect main power to the dryer at the disconnect or terminals in the upper right  
corner of the control enclosure.  
Install a fused disconnect with a lockout feature in the power main leading to the dryer.  
The power drop must include a ground wire.  
Make sure all electrical connections are tight.

3-4 Setup Procedures  
This section provides the procedures necessary for configuring your Dehumidifying Dryer.  
Configuration of your dryer includes checking for proper blower rotation, making  
dryer/drying hopper process air connections and the optional aftercooler (on 15 and 30 cfm  
models). We recommend that you carry out these procedures in the order given here.  
Note: Before carrying out these procedures, install all equipment as  
described in this section.  
Checking for Proper Blower Rotation  
Three-Phase Models  
Caution!  
In three-phase models, incorrect phasing of power leads can cause  
backward rotation of blower motors and CONTAMINATION OF THE  
DESICCANT!  
Always check blower rotation before putting material in the drying hopper!  
The blower is rotating properly when air flows from the delivery outlet.  
Note: Holding your hand in front of the air return will also indicate if the  
blower rotates in the proper direction.  
If the three-phase blower rotates improperly, reverse any two wires at the fused disconnect  
outside the dryer or at the disconnect/terminal in the control enclosure. This assures that the  
blower rotates in the proper direction.  
Making Dryer/Drying Hopper Process Air Connections  
Floor Mount Models  
When making process air connections to your floor mounted dryer, ensure that you take into  
consideration and make arrangements for the following:  
Use high-temperature flexible dryer hose or rigid tubing to connect the dryer to the  
drying hopper.  
Keep the delivery hose to the drying hopper as short as possible to minimize heat loss.  
We strongly recommend insulated hose for maximum energy savings.  
Do not use insulated hose on the return from the drying hopper.  
The return air to the blower must be 150°F (66ºC) or below. If the return air  
temperature is not below this point, you should purchase and install the optional  
aftercooler to remove excessive heat. Consult the manufacturer for more information.  
Aftercooler considerations also apply to machine-mount models.  
Make sure that hoses are not kinked or collapsed.  
Drying hopper air inlet and outlet locations vary, but always connect hoses so the dry  
process air from the dryer enters the bottom of the drying hopper and flows out the top  
to return to the dryer inlet.  
Thermocouple is to be installed at drying hopper’s delivery tube.

Drying Hopper Air Trap Considerations  
Our exclusive air trap assembly on the top of the drying hopper prevents ambient air from  
contaminating the material being dried. To ensure that your unit will operate at peak  
efficiency, do the following:  
Keep the material level at the mid point of the air trap  
This can be achieved by utilizing a hopper loader or vacuum conveying system to  
supply material to the drying system.  
Optional Aftercooler  
Water-cooled 15 and 30 cfm models use a water-to-air heat exchanger as an aftercooler.  
Cooling water is required for this design (3 gpm at 85°F or lower). Return air from the  
hopper passes through the air filter to trap fines and dust before entering the heat exchanger.  
Installing Water Lines  
(Hose and Hose Clamp)  
When installing the water lines, ensure that the aftercooler utilizes either tower, chilled or city  
water up to 85°F (29°C). Recommended flow rate is three (3 gpm) gallons per minute (11  
liters per minute).  
3-5 Initial Start-up  
Pre-Startup Checks  
; Check the process and return hoses for tight connections.  
; Check all companion equipment, such as the drying hopper; verify that the loading  
system is ready for operation.  
; Verify that all dryer electrical connections are tight.  
Caution!  
Clean the rust-preventing oil from inside the drying hopper.  
Failure to clean the hopper fouls the desiccant and voids your warranty!  
; Verify that the dryer’s thermocouple is properly connected in the center of the drying  
hopper’s delivery tube.  
; Verify that the temperature control has been configured for your specified scale (ºF  
or ºC).  
Starting Up the Dryer  
1. Turn on (energize) the disconnect switch in your power drop, then turn on the  
disconnect switch on the dryer (3 phase only).  
2. Turn the system ON/OFF switch to ON to start the dryer.  
3. Close the slidegate at the bottom of the drying hopper.  
Make sure that the blowers turn in the right direction.  
4. Fill the drying hopper with material. Dryer performance is compromised if hopper is  
not full!  
5. If your dryer has a water-cooled aftercooler, make sure that sufficient cooling water  
(3gpm at 85°F or lower) flows properly through the coil and that you have bled any  
15, 30, & 60 cfm Compact Dryers

trapped air from the system. Make sure the aftercooler has the proper supply water  
temperature.  
6. Set the process set point on the temperature controller.  
7. After the proper pre-drying time for the initial hopper fill has elapsed, fully open the  
drying hopper slide gate.  
Note: To allow proper residence time during continuous processing,

4-2 Dryer Operation Procedures  
Controller Operation  
1. Turn the disconnect (if applicable) on the control panel to the ON position. Power is  
applied to the voltage line fuses, line side of the control power switch.  
2. Turn the control power switch to the ON position. Power is applied to the  
temperature control, programmable relay and dew point controller. The valve will  
move to the start position as follows:  
a. The valve motor rotates until the cam switch makes 2 transitions.  
b. If the cam switch does not make a transition within 10 seconds, a valve  
motor fault is generated. “VALVE MTR” is displayed on the relay screen,  
the alarm light is activated. The valve motor, heaters, and blower shut off.  
To restart the dryer, cycle control power to deactivate the alarm light and  
restart the valve motor sequence.  
Note: The relay screen which contains the Alarm Display Messages is located  
inside the controller enclosure. For a list of Alarm Display Messages,  
see Page 32.  
WARNING! Do not attempt to check the Alarms on the Controller located within the  
unit enclosure unless you are a qualified electrician!  
c. The valve will normally complete one full cycle (revolution).  
If the drying process shuts down due to an alarm, the dryer has been setup to  
have the following operational features:  
The bed in process at power-down will remain in process.  
The bed in regeneration at power-down will remain in regeneration.  
The regeneration timing cycle will restart from the beginning.  
3. Once the control power is on and no fault conditions exist, the dryer will start as  
follows:  
a. The process/regen blower is started.  
b. The process heater is turned on and controlled by the E5CN controller.  
c. The regen heater is turned on and the regeneration timing sequence is  
initiated. For default timing settings for regeneration, see the table below.

4. If either the left or right bed safety temperature switch opens, a regen heater fault is  
generated. “HIGH TEMP” is displayed on the relay screen. The alarm light is  
activated.  
5. If the process temperature controller faults or the process heater safety switch opens,  
a heater fault is generated. “HIGH TEMP” is displayed on the relay screen. The  
alarm light is activated. The process heater, regen heater, and process/regen blower  
are turned off. (Requires turning the dryer OFF).  
6. If the process blower overloads trips, a process blower fault is generated. “PROC  
BLWR” is displayed on the relay screen. The alarm light is activated. The process  
heater, regen heater, and process/regen blower are turned off (3 phase only).  
7. The valve position limit switch enables the right bed heater and provides an input  
signal to the programmable relay when actuated by the cam lobe. When the cam  
verifies position is high, the right bed is activated. When the cam verifies position is  
low, the left bed is activated. Each heater is ON-OFF controlled.  
8. Upon completion of the HEAT portion of the regeneration sequence, the regen  
heaters are disabled by the programmable relay and the COOL time begins.  
9. Once the Cool time has expired, the valve motor is turned on until the cam switch  
makes a transition. Upon making a transition, the timing sequence is restarted for the  
new bed.  
10. When no fault conditions exist, the display reads “SYSTEM NORMAL”.  
11. The top 2 lines of the display show the HEAT and COOL times (in minutes) for the  
regeneration sequence. Changes to these times can be made by the operator as  
follows:  
a. Press the up or down arrow until the cursor is positioned at the number to be  
changed.  
b. Press the “+” key to increment the number, or the “-“ key to decrement the  
number.  
c. Press the “OK” key to accept the value and write to the relay memory.

5-2 Preventative Maintenance  
This section describes maintenance procedures which will increase the longevity and  
efficiency of your dehumidifying dryer. Perform them at the regular intervals listed on the  
dryer checklist on the previous page.  
Servicing Process Air Filters  
Caution!  
Operating the dryer without the process air filter installed voids your  
warranty!  
Filter cleaning is an important part of your dryer maintenance program.  
Dehumidifying dryers have a single cartridge canister-type filter in the process air loop. The  
filter protects blowers from plastic fines drawn in from the drying hopper and prevents the  
desiccant from being contaminated. Regular filter cleaning is essential to keep your dryer  
operating at peak efficiency.  
You can blow or vacuum the dirt out of the filter with compressed air, but remember, it could  
become damaged from high-pressure blowing.  
Recommendations for Cleaning and Replacing Filters  
Turn off and/or lock out electrical power to the dryer.  
Remove the threaded fastener securing the filter access cover, then remove the cover.  
Remove the nut on the center retaining rod to remove the filter cartridge.

Vacuuming  
Try vacuum-cleaning a soiled filter first. Vacuuming removes most large particles and  
surface contaminants, and may suffice for the first time you clean a filter. Use a commercial-  
duty (recommended) or household vacuum cleaner. Vacuum the filter from the air intake  
(dirty) side only.

Cleaning with Compressed Air  
Blow clean, dry compressed air up and down the pleats, blowing out the filter  
from the inside out. Remove loose dirt from the filter with compressed air or  
vacuum from the outside.  
Caution!  
DO NOT clean/wash filter with water!  
After each cleaning:  
Inspect the filter element. Briefly hold a light bulb behind the element  
and look for any fatigued paper or residual dirt. Inspect for holes and  
tears by looking though the filter toward a bright light. Check for  
damaged gaskets or dented metal parts. Do not re-use a damaged  
filter!  
Check the gasket for damage. A damaged gasket allows contaminants  
into the process. Replace as needed.  
Servicing the Dew Point Monitor  
The accuracy of the dew point monitor on mini dryer systems depends on proper operation of  
the dew point sensor and the control board. The dew point sensor is in the process air stream  
and is therefore susceptible to contamination.  
Dew point sensor life depends on:  
Air temperature and flow passing over the sensor.  
The amount of fines (dust) in the process air.  
The amount of plasticizer vapor in the process air.  
Once every six months, the dryer operator should monitor the initial dew point sensor  
readings and establish a periodic replacement schedule as needed.  
Caution!  
Do not attempt to check the continuity or resistance of the dew point  
sensor.  
5-3 Corrective Maintenance  
This section provides you with the information necessary to correct or repair any issues  
which might appear during the normal operation of your dehumidifying dryer. Although we  
have listed how to perform these procedures, it is recommended that you call the Service  
Department to have any in-depth maintenance performed.  
Symptoms of Worn Desiccant  
The moisture absorption capacity of the desiccant used in your dehumidifying dryer degrades  
after an indefinite period of time. Useful life depends on variables such as the condition of the  
process filter, how much dust and fines have been passed through the filter and got into the  
desiccant chamber, and plasticizer vapors in the return air.

WARNING! Handling desiccant material is HAZARDOUS.  
Wear an N-100 type safety filter mask or equivalent to avoid prolonged  
breathing of desiccant dust. Wear safety goggles and gloves to avoid  
contact with eyes and skin.  
Handle with adequate ventilation.  
Wash hands thoroughly after handling.  
+ FIRST AID +  
In case of eye contact, immediately flush eyes  
with plenty of water for at least 15 minutes.  
SEE A PHYSICIAN IMMEDIATELY IF IRRITATION PERSISTS.  
Replacing Worn Desiccant  
Caution!  
DESICCANT BEDS ARE HOT DURING OPERATION.  
To avoid burn hazard, make sure desiccant beds are sufficiently cool  
before replacing worn desiccant.  
To access the Desiccant Bed:  
1. Disconnect electrical power to the dryer.  
2. Using a 1/8” Allen wrench, remove the 10-24 button head screws holding the top,  
back and side panels to the frame and back of the dryer.  
3. Disconnect the three (3) plugs for the valve motor, switch, and blower (15 cfm only)  
4. Remove four (4) nuts at each corner of the top casting.

6-1 Introduction  
The utmost in safety precautions should be observed at all times when working on or around  
the machine and the electrical components. All normal trouble-shooting must be  
accomplished with the power off, line fuses removed, and with the machine tagged as out of  
service.  
The use of good quality test equipment cannot be over-emphasized when troubleshooting is  
indicated. Use a good ammeter that can measure at least twice the AC and DC current that  
can be encountered for the machine. Be sure that the voltmeter has at least minimum  
impedance of 5,000 OHMS-per-volt on AC and 20,000 OHMS-per-volt on DC scales.  
Popular combination meters, VOM and VTVM can be selected to provide the necessary  
functions.  
Before making haphazard substitutions and repairs when defective electrical components are  
malfunctioning, we recommend that you check the associated circuitry and assemblies for  
other defective devices. It is common to replace the obviously damaged component without  
actually locating the real cause of the trouble. Such hasty substitutions will only destroy the  
new component. Refer to wiring diagrams and schematics.  
Locating mechanical problems, should they occur, is relatively straightforward. When  
necessary, refer to the parts catalog section.

6-2 Determining Temperature Controller Errors or Sensor Errors  
Using a Thermocouple  
If the controller displays a temperature that is close to room temperature (70ºF/21ºC) when  
you short-circuit controller input terminals, the controller is normal and the sensor is probably  
broken, short-circuited, or incorrectly wired.  
Other service problems or questions can be answered by contacting the Service  
Department.
