SECTION I  
IMPORTANT INFORMATION  
A. RECEIVING AND HANDLING  
The dryer is shipped in a protective stretch wrap cover with protective cardboard corners and top cover (or  
optional box) as a means of preventing damage in transit. Upon delivery, the dryer and/or packaging, and wooden  
skid should be visually inspected for shipping damage. If any damage whatsoever is noticed, inspect further  
before delivering carrier leaves.  
Dryers damaged in shipment:  
1. ALL dryers should be inspected upon receipt and before they are signed for.  
2. If there is suspected damage or actual damage, the trucker’s receipt should be so noted.  
3. If the dryer is damaged beyond repair, it should be refused. Those dryers, which were not damaged in a  
damaged shipment, should be accepted, but the number received and the number refused must be noted  
on the receipt.  
4. If you determine that the dryer was damaged after the trucker has left your location, you should call the  
delivering carrier’s freight terminal immediately and file a claim. The freight company considers this concealed  
damage. This type of freight claim is very difficult to get paid and becomes extremely difficult when more  
than a day or two passes after the freight was delivered. It is your responsibility to file freight claims.  
Dryer/parts damaged in transit cannot be claimed under warranty.  
5. Freight claims are the responsibility of the consignee, and ALL claims must be filed at the receiving end.  
ADC assumes no responsibility for freight claims or damages.  
6. If you need assistance in handling the situation, please contact theADC Traffic Manager at (508) 678-9000.  
IMPORTANT: The dryer must be transported and handled in an upright position at ALL times.

C. DRYER ENCLOSURE REQUIREMENTS  
Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of  
12-inches (30.48 cm) (18-inches [45.72 cm] or more is recommended for ease of installation, maintenance, and  
service) above the dryer outer top, except along the front of the dryer which may be partially closed in if desired.  
The clearance between the bulkhead header and the dryer must bea minimum of 4-inches (10.16 cm) and must  
not extend more than 4-inches (10.16 cm) to the rear of the front. The bulkhead facing must not be closed in  
ALL the way to the top of the dryer. A 1-inch (2.54 cm) clearance is required.  
NOTE: Allowances must be made for opening the control door.  
Dryers may be positioned sidewall to sidewall. However, a 1/16” (1.5875 mm) minimum allowance must be  
made for the opening and closing of the control door and the lint door. It is suggested that the dryer be positioned  
about 2 feet (0.61 meters) away from the nearest obstruction for ease of installation, maintenance, and service  
(to be measured from the back guard). Refer to the illustration above for details.  
NOTE: Air considerations are important for proper and efficient operation.  
IMPORTANT: Even though a minimum of only 12-inches (30.48 cm) is required, 18-inches (45.72  
cm) or more is suggested. The additional clearance is advantageous for ease of  
installation and service.  
IMPORTANT: When fire sprinkler systems are located above the dryers, a minimum of 18-inches  
(45.72 cm) above the dryer console (module) is required. Dryers may be positioned  
sidewall to sidewall, however, a 1/16” (1.5875 mm) minimum allowance is required  
between dryers (or wall) for ease of installation and maintenance. Allowances must  
be made for the opening and closing of the control door and the lint door.

D. FRESH AIR SUPPLY REQUIREMENTS  
When the dryer is operating, it draws in room air, heats it, passes this air through the basket (tumbler), and  
exhausts it out of the building. Therefore, the room airmust be continually replenished from the outdoors. If the  
make-up air is inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and  
sail switch “fluttering” problems may result, as well as premature motor failure from overheating.  
Air supply (make-up air) must be given careful consideration to assure proper performance of each dryer. An  
unrestricted source of air is necessary for each dryer. An airflow of 1,200 cfm (cubic feet per minute) (33.98  
cmm [cubic meters per minute]) must be supplied to each dryer. As a general rule, an unrestricted air entrance  
from the outdoors (atmosphere) of a minimum of 1-1/2 square feet (0.41 square meters) is required for each  
dryer. The dryer must be installed with provisions for adequate combustion and make-up air supply.  
To compensate for the use of registers or louvers used over the openings, this make-up airmust beincreased by  
approximately thirty-three percent (33%). Make-up air openings should not be located in an area directly near  
where exhaust vents exit the building.  
It is not necessary to have separate make-up air openings for each dryer. Common make-up air openings are  
acceptable. However, they must be set up in such a manner that the make-up air is distributed equally to ALL  
the dryers.  
EXAMPLE: For a bank of four (4) dryers, two (2) unrestricted openings measuring 2 feet by 1-1/2 feet  
(0.61 meters by 0.46 meters [6 square feet] [0.56 square meters]) are acceptable.  
Allowances must be made for remote or constricting passageways or where dryers are located at excessive  
altitudes or predominantly low pressure areas.  
IMPORTANT: Make-up air must be provided from a source free of dry cleaning solvent fumes.  
Make-up air that is contaminated by dry cleaning solvent fumes will result in  
irreparable damage to the motors and other dryer components.  
NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.

E. EXHAUST REQUIREMENTS  
1. General Exhaust Ductwork Information  
Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork  
will create excessive back pressure which results in slow drying, increased use of energy, overheating of  
the dryer, and shutdown of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler)  
hi-limit thermostats. The dryer must be installed with a proper exhaust duct connection to the outside.  
CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors.  
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORKCAN  
CREATE A POTENTIAL FIREHAZARD.  
IMPORTANT: It is recommendedthat exhaust or booster fans not be used in the exhaust ductwork  
system.  
The ductwork should be laid out in such a way that the ductwork travels as directly as possible to the  
outdoors with as few turns as possible. Single or independent dryer venting is recommended.  
HORIZONTAL VENTING:  
When single dryer venting is used, the length of the ductwork from the dryer to the outside exhaust outlet  
must not exceed 15 feet (4.6 meters). The minimum diameter of this ductwork must be at least  
10-inches (25.4 cm). In the case of multiple (common) dryer venting, the distance from the last dryer to the  
outside exhaust outlet must not exceed 15 feet (4.6 meters). The shape of the ductwork is not critical so  
long as the minimum cross-sectional area is provided. It is suggested that the use of 90° turns be avoided;  
use 30° and/or 45° angles instead. The radius of the elbows should preferably be 1-1/2 times the  
diameter of the duct. Including basket (tumbler)/dryer elbow connections or elbows used for outside  
protection from the weather, no more than two (2) elbows should be used in the exhaust duct run. If more  
than two (2) elbows are used, the cross-sectional area of the ductwork must be increased. ALL ductwork  
should be smooth inside with no projections from sheet metal screws or other obstructions, which will  
collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be connected.  
ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building. Inspection  
doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning of  
lint from the ductwork.  
VERTICAL VENTING:  
When single dryer venting is used, the length of the ductwork from the dryer to the outside exhaust outlet  
must not exceed 20 feet (6.1 meters). The minimum diameter of this ductwork must be at least  
12-inches (30.48 cm). In the case of multiple (common) dryer venting, the distance from the last dryer to  
the outside exhaust outlet must not exceed20 feet (6.1 meters). The shape of the ductwork is not critical  
so long as the minimum cross-sectional area is provided. It is suggested that the use of 90º turns be  
avoided; use 30º and/or 45º bends instead. The radius of the elbows should preferably be 1-1/2 times the  
diameter of the duct. ALL ductwork should be smooth inside with no projections from sheet metal  
screws or other obstructions, which will collect lint. When adding ducts, the duct to be added should  
overlap the duct to which it is to be connected. ALL ductwork joints must be taped to prevent moisture  
and lint from escaping into the building. Inspection doors should be installed at strategic points in the  
exhaust ductwork for periodic inspection and cleaning of lint from the ductwork.

NOTE: As per the National Fuel Gas Code, “Exhaust ducts for Type 2 clothes dryers shall be  
constructed of sheet metal or other noncombustible material. Such ducts shall be equivalent  
in strength and corrosion resistance to ducts made of galvanized sheet steel not less than  
0.0195-inches (26 gauge [0.05 mm]) thick.”  
IMPORTANT: Exhaust back pressure measured by a manometer in the exhaust duct must be no less  
than 0 and must not exceed 0.3 inches (0.74 mb) of water column (W.C.).  
IMPORTANT: Minimum ductwork diameter for horizontal venting is 10-inches (25.4 cm) and for  
vertical venting the minimum is 12-inches (30.48 cm).  
NOTE: When the exhaust ductwork passes through a wall, ceiling, or roof made of combustible  
materials, the opening must be 2-inches (5.08 cm) larger than the duct (all the way around).  
The duct must be centered within this opening.  
a. Outside Ductwork Protection  
1) To protect the outside end of the horizontal ductwork from the weather, a 90° elbow bent downward  
should be installed where the exhaust exits the building. If the ductwork travels vertically up  
through the roof, it should be protected from the weather by using a 180° turn to point the opening  
downward. In either case, allow at least twice the diameter of the duct between the duct opening  
and the nearest obstruction.  
IMPORTANT: DO NOT use screens, louvers, or caps on the outside opening of the exhaust  
ductwork.  
2. Single Dryer Venting  
When possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust duct should  
be laid out in such a way that the ductwork travels as directly as possible to the outdoors with as few turns  
as possible. It is suggested that the use of 90° turns in the ducting be avoided; use 30° and/or 45° angles  
instead. The shape of the exhaust ductwork is not critical so long as the minimum cross-sectional area is  
provided.  
IMPORTANT: Minimum duct size for a dryer that is vented horizontally is 10-inches (25.4 cm) for a  
round duct or an equivalent of 80 square inches (516.1 square centimeters). THE  
DUCT SIZE MUST NOT BE REDUCED ANYWHERE DOWNSTREAM  
OF THE DRYER.

IMPORTANT: Exhaust back pressure measured by a manometer in the exhaust duct must be no less  
than 0 and must not exceed 0.3 inches (0.74 mb) of water column (W.C.).  
IMPORTANT: Minimum duct size for a dryer that is vented vertically is 12-inches (30.48 cm) for a  
round duct or an equivalent of 80 square inches (516.1 square centimeters). THE  
DUCT SIZE MUST NOT BE REDUCED ANYWHERE DOWNSTREAM  
OF THE DRYER.  
IMPORTANT: For extended ductwork runs, the cross section area of the ductwork can only be  
increased to an extent. When the ductwork approaches the maximum limits noted in  
this manual, a professional heating, venting, and air conditioning (HVAC) firm should  
be consulted for proper venting information.  
ALL ductwork should be smooth inside with no projections from sheet metal screws or other obstructions,  
which will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be  
connected. ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building.  
Inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and  
cleaning of lint from the ductwork.  
NOTE: When the exhaust ductwork passes through a wall, ceiling, or roof made of combustible  
materials, the opening must be 2-inches (5.08 cm) larger than the duct (all the way around).  
The duct must be centered within this opening.

H. PREPARATION FOR OPERATION/START-UP  
The following items should be checked before attempting to operate the dryer:  
1. Read ALL CAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer.  
2. Check incoming supply voltage to be sure that it is the same as indicated on the dryer data label affixed to  
the left side panel area behind the top control (access) door. In the case of 208 VAC or 240 VAC, the  
supply voltage must match the electric service exactly.  
3. GAS MODELS - check to assure that the dryer is connected to the type of heat/gas indicated on the dryer  
data label.  
4. GAS MODELS - the sail switch damper assembly was installed and adjusted at the factory prior to  
shipping. However, each sail switch adjustment must be checked to assure that this important safety  
control is functioning.  
5. GAS MODELS - be sure that ALL gas shutoff valves are in the open position.  
6. Be sure ALL back panels (guards) and electric box covers have been replaced.  
7. Check ALL service doors to assure that they are closed and secured in place.

I. PREOPERATIONAL TESTS  
ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test  
should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or  
due to marginal location (installation) conditions.  
1. Turn on electric power to the dryer.  
a. Open ALL shutoff valves.  
2. Refer to the Operating Instructions for starting your particular model dryer.  
a. Gas Dryers  
1) When a gas dryer is first started (during initial start-up), the burner has a tendency not to ignite on  
the first ignition attempt. This is because the gas supply piping is filled with air, so it may take a few  
minutes for the air to be purged from the lines.  
NOTE: During the purging period, check to be sure that ALL gas shutoff valves are open.  
NOTE: Gas dryers are equipped with a Direct Spark Ignition (DSI) system, which has internal  
diagnostics. If ignition is not established within three (3) times, the heat circuit in the DSI  
module will “LOCKOUT” until it is manually reset. To reset the DSI system, open and close  
the main door and restart the dryer.  
2) A gas pressure test should be taken at the gas valve pressure tap of each dryer to assure that the  
water column (W.C.) pressure is correct and consistent.  
NOTE: Water column pressure requirements (measured at the gas valve pressure tap):  
Natural Gas----------------- 3.5 Inches (8.7 mb) Water Column.  
Liquid Propane (L.P.) Gas -- 10.5 Inches (26.1 mb) Water Column.  
IMPORTANT: There is no regulator provided in an L.P. dryer. The water column pressure must be  
regulated at the source (L.P. tank), or an external regulator must be added to each  
dryer.  
3. Make a complete operational check of ALL safety related circuits:  
a. Door Switch(es)  
b. Hi-Limit Thermostats  
c. Sail Switch  
30  
Download from Www.Somanuals.com. All Manuals Search And Download.  
NOTE: To check for proper sail switch operation, open the main door and while holding main door  
switch plunger in, start dryer. Dryer should start but heat circuit should not be activated (on).  
If the heat system is activated, the sail switch is improperly adjusted and must be adjusted by  
bending the actuator arm of the sail switch toward the burner box. If the actuator arm is bent  
too far toward the burner box of the dryer, the dryer may not have heat when needed. After  
any adjustment to the sail switch, the above procedure must be repeated to verify proper  
operation of the sail switch.  
4. The dryer should be operated through one (1) complete cycle to assure that no further adjustments are  
necessary and that ALL components are functioning properly.  
BASKET (TUMBLER) COATING  
The basket (tumbler) is treated with a protective coating. We suggest dampening old garments or cloth material  
with a solution of water and nonflammable mild detergent and tumbling them in the basket (tumbler) to remove  
this coating.  
5. Make a complete operational check of ALL operating controls.  
a. For microprocessor controller (computer) model check programs/selections...  
1) Each microprocessor controller (computer) has been preprogrammed by the factory with the most  
commonly used parameter (program) selections. If computer program changes are required, refer  
to the computer programming manual, which was shipped with the dryer.  
6. Check the electric service phase sequence (3-phase [3ø] models only). While the dryer is operating, check  
to see if the blower wheel (impellor/fan) is rotating in the proper direction. Looking from the front, the  
blower wheel (impellor/fan) should spin in the clockwise (CW) direction. If it is, the phasing is correct. If  
the phasing is incorrect, reverse two (2) of the three (3) leads at connections L1, L2, and L3 of the power  
supply to the dryer.  
IMPORTANT: If the blower wheel (impellor/fan) is rotating in the wrong direction, this will not only  
drastically reduce drying efficiency, but it can also cause premature component failure.  
7. Reversing basket (tumbler) dryers should never be operated with less than a 50 lb (22 kg) load (dry  
weight), since the load’s weight affects basket (tumbler) coast time during a direction reversal command.  
It is important that the basket (tumbler) come to a complete stop prior to starting in opposite direction.

SECTION VI  
ROUTINE MAINTENANCE  
A. CLEANING  
A program and/or schedule should be established for periodic inspection, cleaning, and removal of lint from  
various areas of the dryer, as well as throughout the ductwork system. The frequency of cleaning can best be  
determined from experience at each location. Maximum operating efficiency is dependent upon proper air  
circulation. The accumulation of lint can restrict this airflow. If the guidelines in this section are met, an ADC  
dryer will provide many years of efficient, trouble free, and most importantly, safe operation.  
WARNING: LINT FROM MOST FABRICS IS HIGHLY COMBUSTIBLE. THE  
ACCUMULATION OF LINT CAN CREATE A POTENTIAL FIRE HAZARD.  
WARNING: KEEP DRYER AREA CLEAR AND FREE FROM COMBUSTIBLE  
MATERIALS, GASOLINE, AND OTHER FLAMMABLE VAPORS AND  
LIQUIDS.  
NOTE: Suggested time intervals shown are for average usage which is considered six (6) to eight (8)  
operational (running) hours per day.  
IMPORTANT: Dryer produces combustible lint and must be exhausted to the outdoors. Every 6  
months, inspect the exhaust ducting and remove any lint build up.  
SUGGESTED CLEANING SCHEDULE  
EVERY THIRD OR FOURTH LOAD  
Clean the lint screen every third or fourth load. A clogged lint screen will cause poor dryer performance. The  
lint screen is located behind the lint door in the base of the dryer. Open the lint door, brush the lint off of the lint  
screen, and remove the lint. Inspect the lint screen and replace if torn.  
NOTE: The frequency of cleaning the lint screens can best be determined from experience at each  
location.  
WEEKLY  
Clean lint accumulation from the lint chamber, thermostat, and microprocessor temperature sensor (sensor  
bracket) area.  
WARNING: TO AVOID HAZARD OF ELECTRICAL SHOCK, DISCONTINUE  
ELECTRICAL POWER SUPPLY TO THE DRYER.  
37  
Download from Www.Somanuals.com. All Manuals Search And Download.  
90 DAYS  
1. Remove lint from around basket (tumbler), drive motors, and surrounding areas.  
2. Remove lint from gas valve burner area with a dusting brush or vacuum cleaner attachment.  
3. Clean any lint accumulation in and around both the blower and drive motor casing openings.  
EVERY 6 MONTHS  
Inspect and remove lint accumulation in customer furnished exhaust ductwork system and from dryer’s internal  
exhaust ducting.  
NOTE: THE ACCUMULATION OF LINT IN THE EXHAUST DUCTWORK CAN  
CREATE A POTENTIAL FIRE HAZARD.  
NOTE: DO NOT OBSTRUCT THE FLOW OF COMBUSTION ANDVENTILATION AIR.  
CHECK CUSTOMER FURNISHED BACK DRAFT DAMPERS IN THE EXHAUST  
DUCTWORK. INSPECT AND REMOVE ANY LINT ACCUMULATION, WHICH  
CAN CAUSE THE DAMPER TO BIND OR STICK.  
NOTE: A back draft damper that is sticking partially closed can result in slow drying and shutdown of  
heat circuit safety switches or thermostats.  
NOTE: When cleaning the dryer cabinets, avoid using harsh abrasives. A product intended for the  
cleaning of appliances is recommended.  
B. ADJUSTMENTS  
7 DAYS AFTER INSTALLATION AND EVERY 6 MONTHS THEREAFTER  
Inspect bolts, nuts, screws, (bearing setscrews), grounding connections, and nonpermanent gas connections  
(unions, shutoff valves, and orifices). Motor and drive belts should be examined. Cracked or seriously frayed  
belts should be replaced. Tighten loose V-belts when necessary. Complete operational check of controls and  
valves. Complete operational check of ALL safety devices (door switches, lint drawer switch, sail switch,  
burner, and hi-limit thermostats).  
C. LUBRICATION  
The motor bearings, idler bearings...and under normal/most conditions the basket (tumbler) bearings are permanently  
lubricated. It is physically possible to relubricate the basket (tumbler) bearings if you choose to do so even  
though this practice is not necessary. Use ShellAlvania #2or its equivalent. The basket (tumbler) bearings used  
in the dryer DO NOT have a grease fitting. Provisions are made in the bearing housing for the addition of a  
grease fitting which can be obtained elsewhere, or from ADC by ordering kit Part No. 882159, which includes  
two (2) fittings.

Download from Www.Somanuals.com. All Manuals Search And Download.  
2. For Models With Johnson Controls Direct Spark Ignition (DSI) Module (G760)  
Theory Of Operation:  
Start the drying cycle. When the gas burner ignites within the chosen trial for ignition time (6-seconds), the  
flame sensor detects gas burner flame and signals the DSI module to keep the gas valve open...as long as  
there is a call for heat. The DSI module will “LOCKOUT” if the gas burner flame is not sensed at the end  
of the trial for ignition period. The trial for ignition period will be repeated for a total of three (3) retries/trials  
(the initial try and two [2] more retries/trials). If the flame is not sensed at the end of the third retry/trial  
(inter-purge period of 30-seconds) the DSI module will “LOCKOUT” (light emitting diode [L.E.D.] flashes).  
A steady L.E.D. indicator indicates normal operation.  
No L.E.D. indicator indicates a power or an internalfailure has occurred.

S.A .F .E. Sy st em In A ct ion  
The exclusive Sensor Activated Fire Extinguishing (S.A.F.E.) System will extinguish fires  
that may start in the drying basket (tumbler). A series of sensors positioned throughout  
the basket (tumbler) and interfaced with the microprocessor will trigger the S.A.F.E.  
system water jet(s) to quickly extinguish the flames. The water jet(s) remain on for 2  
minutes and will automatically activate again if a fire condition remains or reignites. While  
the water jet(s) are activated, the basket (tumbler) will jog to move the water throughout  
the load. The microprocessor will display that the system was activated and will continue  
to display until the dryer is attended to.

OPTIONAL MANUAL BYPASS  
Provisions are made in the dryer Sensor Activated Fire Extinguishing (S.A.F.E.) system for the installation of an  
optional manual bypass. Depending on the model dryer, the connections for the manual bypass are made at the  
“T” or “four way” fitting located in the outlet supply side of the water solenoid valve. The use and connections  
of this manual bypass are at the option or discretion of the owner.  
The water connection for the manual bypass is made to the “T” or “four way” fitting which has a 3/8” F.P.T. and  
a coupling must be used to provide the minimum 1/2” supply (feed) line.  
If the rear area of the dryer, or the water supply is located in an area where it will be exposed to cold/freezing  
temperatures, provisions must be made to protect these water lines from freezing.  
WARNING: If the water in the supply line or water solenoid valve freezes, the S.A.F.E. system will  
be INOPERATIVE!!  
The manual ball cock shutoff valve must be located outside of the dryer at a distance from the dryer where it  
is easily accessible.  
3. Electrical Requirements  
No independent external power source or supply connection is necessary. The 24 volt power to operate the  
S.A.F.E. system is accomplished internally in the dryer (from the dryer controls).  
WARNING: Electrical power must be provided to the dryer at ALL times. If the main electrical  
power supply to the dryer is disconnected, the S.A.F.E. system is INOPERATIVE!!

Sensor Activated  
Fire Extinguishing (S.A.F.E.) System  
Theory of Operation  
While the dryer is in an idle state or 20-seconds after the heat turns off, the Phase 7 control monitors the  
S.A.F.E. system probe located in the top of the basket (tumbler) chamber and records the minimum temperature.  
If the minimum recorded S.A.F.E. system probe temperature is no less than 120° F (48° C) and the control  
detects a 50° rise in temperature, this will be the trip point and the S.A.F.E. system routine will activate.  
While a drying cycle is in process and the heat has turned on at least once, the Phase 7 control monitors the  
exhaust temperature transducer. If the drying cycle temperature set point is set greater than 160° F (71° C) and  
the control detects an exhaust temperature rise 25° F greater than set point, this will be the trip point and the  
S.A.F.E. system routine will activate. If set point is below 160° F (71° C) the trip point will be 185° F (85° C).  
Once the S.A.F.E. system routine is activated, waterwill be injected into the basket (tumbler) chamber. Anytime  
water is being injected into the basket (tumbler); the basket (tumbler) drive will turn the load for 1-second every  
15-seconds. This process will continue for a minimum of 2 minutes. After 2 minutes has elapsed, the control will  
check if the temperature remained above trip point, if so water will remain on. The control will continue to check  
if temperature is above trip point every 30-seconds. If the water has been on for a constant 10 minutes, the  
water will be turned off regardless of the temperature. If the temperature has dropped below trip point, the  
control will turn off the water prior to 10 minutes.  
SYSTEM RESET  
After the microprocessor determines that the situation is under control and shuts the water being injected into the  
basket (tumbler) off, the microprocessor display will read “S.A.F.E. System activated,” and the horn/tone will  
sound until reset manually.  
To reset the microprocessor once the control displays “S.A.F.E. System activated,” press the red  
keyboard (touch pad).  
key on the  
OPL S.A.F.E. SYSTEM CHECK PROCEDURE  
The operation of the water solenoid valve can be tested to insure that the water supply system and valve are  
functional. Before attempting system check, be sure that ALL water supply shutoff valves to the dryer are in  
the OPEN position, and the dryer must be in the “READY” mode where no cycle is loaded or in progress.  
The procedure is as follows:  
1. Press and hold the RED STOP key (while in “READY” mode and no cycle in progress).  
2. Press and hold the “A” key.  
3. Water valve will open and water will be dispensed into basket (tumbler) area as long as both keys are held.  
IMPORTANT: This is a test function only and the keys should be held and system activated for only  
a second or so, otherwise water will accumulate in various places in the dryer.
