ROUTINE MAINTENANCE  
NOTE: Units are to be inspected and serviced by qualied service personnel only.  
Routine maintenance is required annually or semi-annually, depending upon annual usage.  
1. Clean the unit air intake lter at least every 250 to 300 fan hours of operation or when the unit’s indicator light is on if  
so equipped. Clean the lters with a mild detergent in warm water and allow to dry thoroughly before reinstalling.  
2. The indoor coil (evaporator coil), the outdoor coil (condenser coil) and base pan should be inspected periodically (yearly  
or bi-yearly) and cleaned of all debris (lint, dirt, leaves, paper, etc.). Clean the coils and base pan with a soft brush and  
compressed air or vacuum. If using a pressure washer, be careful not to bend the aluminium n pack. Use a sweeping  
up and down motion in the direction of the vertical aluminum n pack when pressure cleaning coils. Cover all electrical  
components to protect them from water or spray. Allow the unit to dry thoroughly before reinstalling it in the sleeve.  
NOTE: Do not use a caustic coil cleaning agent on coils or base pan. Use a biodegradable cleaning agent and degreaser.  
Inspect the indoor blower housing, evaporator blade, condenser fan blade, and condenser shroud periodically (yearly or  
bi-yearly) and clean of all debris (lint, dirt, mold, fungus, etc.) Clean the blower housing area and blower wheel with an  
antibacterial / antifungal cleaner. Use a biodegradable cleaning agent and degreaser on condenser fan and condenser  
shroud. Use warm or cold water when rinsing these items. Allow all items to dry thoroughly before reinstalling them.  
3. Periodically (at least yearly or bi-yearly): inspect all control components, both electrical and mechanical, as well as the  
power supply. Use proper testing instruments (voltmeter, ohmmeter, ammeter, wattmeter, etc.) to perform electrical  
tests. Use an air conditioning or refrigeration thermometer to check room, outdoor and coil operating temperatures.  
Use a sling psychrometer to measure wet bulb temperatures indoors and outdoors.  
4. Inspect the surrounding area (inside and outside) to ensure that the units’ clearances have not been compromised or  
altered.  
5. Inspect the sleeve and drain system periodically (at least yearly or bi-yearly) and clean of all obstructions and debris.  
Clean both areas with an antibacterial and antifungal cleaner. Rinse both items thoroughly with water and ensure that  
the drain outlets are operating correctly. Check the sealant around the sleeve and reseal areas as needed.  
6. Clean the front cover when needed. Use a mild detergent. Wash and rinse with warm water. Allow it to dry thoroughly  
before reinstalling it in the chassis.

PERFORMANCE DATA  
* Rating Conditions: 80 degrees F, room air temp. & 50% relative humidity, with 95 degree F, outside air temp & 40% relative humidity  
Calculate the heat loss of the space to be heated. As long as the heat loss does not exceed the resistance heating capacity rating of the unit, the heating performance will be satisfactory. Change-over  
from heat pump operation to resistance operation on models indicated is automatic at a preset outside ambient temperature of approximately 35°F. If condensate disposal is desired, an optional drain  
kit is available. DEFROST CONTROL: Initiated at 20°F (outdoor coil temperature) and terminated at 43°F (outdoor coil temperature). During defrost, the compressor stops and the electric heat starts,  
then operates with the fan to maintain indoor comfort. Below 43°F, the unit remains in electric heat mode. During electric heat mode, the unit will achieve the following ratings: 11000/9100 BTU/h,  
16.0/14.7 amps, and 3550/2950 watts. DEFROST DRAIN: Drain automatically opens at approximately 50°F in outdoor base pan for defrost condensate disposal.

REFRIGERATION SYSTEM SEQUENCE OF OPERATION  
A good understanding of the basic operation of the refrigera-  
tion system is essential for the service technician. Without  
this understanding, accurate troubleshooting of refrigeration  
system problems will be more difcult and time consuming,  
if not (in some cases) entirely impossible. The refrigeration  
system uses four basic principles (laws) in its operation they  
are as follows:  
the evaporator coil. As it enters the evaporator coil, the  
larger area and lower pressure allows the refrigerant to  
expand and lower its temperature (heat intensity). This  
expansion is often referred to as “boiling”. Since the unit’s  
blower is moving Indoor air across the nned surface of  
the evaporator coil, the expanding refrigerant absorbs  
some of that heat. This results in a lowering of the indoor  
air temperature, hence the “cooling” effect.  
1. Heat always flows from a warmer body to a cooler  
body.”  
The expansion and absorbing of heat cause the liquid  
refrigerant to evaporate (i.e. change to a gas). Once the  
refrigerant has been evaporated (changed to a gas), it is  
heated even further by the air that continues to ow across  
the evaporator coil.  
2. “Heat must be added to or removed from a substance  
before a change in state can occur”  
3. “Flow is always from a higher pressure area to a lower  
pressure area.”  
The particular system design determines at exactly what  
point (in the evaporator) the change of state (i.e. liquid to a  
gas) takes place. In all cases, however, the refrigerant must  
be totally evaporated (changed) to a gas before leaving  
the evaporator coil.  
4. “The temperature at which a liquid or gas changes state  
is dependent upon the pressure.”  
The refrigeration cycle begins at the compressor. Starting  
the compressor creates a low pressure in the suction line  
which draws refrigerant gas (vapor) into the compressor.  
The compressor then “compresses” this refrigerant, raising  
its pressure and its (heat intensity) Temperature.  
The low pressure (suction) created by the compressor  
causes the refrigerant to leave the evaporator through the  
suction line as a cool low pressure vapor. The refrigerant  
then returns to the compressor, where the cycle is  
repeated.  
The refrigerant leaves the compressor through the discharge  
line as a hot high pressure gas (vapor). The refrigerant enters  
the condenser coil where it gives up some of its heat. The  
condenser fan moving air across the coil’s nned surface  
facilitates the transfer of heat from the refrigerant to the  
relatively cooler outdoor air.  
Refrigerant System Components  
When a sufcient quantity of heat has been removed from  
the refrigerant gas (vapor), the refrigerant will “condense”  
(i.e. change to a liquid). Once the refrigerant has been  
condensed (changed) to a liquid it is cooled even further by  
the air that continues to ow across the condenser coil.

The RAC design determines at exactly what point (in the  
condenser) the change of state (i.e. gas to a liquid) takes  
place. In all cases, however, the refrigerant must be totally  
condensed (changed) to a liquid before leaving the condenser  
coil.

Line  
The refrigerant leaves the condenser coil through the  
liquid line as a warm high pressure liquid. It next will pass  
through the refrigerant drier (if so equipped). It is the  
function of the drier to trap any moisture present in the  
system, contaminants, and large particulate matter.  
SEALED REFRIGERATION SYSTEM REPAIRS  
IMPORTANT  
The liquid refrigerant next enters the metering device. The  
metering device is a capillary tube. The purpose of the  
metering device is to “meter” (i.e. control or measure) the  
quantity of refrigerant entering the evaporator coil.  
ANY SEALED SYSTEM REPAIRS TO COOL-ONLY  
MODELS REQUIRE THE INSTALLATION OF A  
LIQUID LINE DRIER. ALSO, ANY SEALED SYSTEM  
REPAIRS TO HEAT PUMP MODELS REQUIRE THE  
INSTALLATION OF A SUCTION LINE DRIER.  
In the case of the capillary tube this is accomplished  
(by design) through size (and length) of device, and the  
pressure difference present across the device.  
Since the evaporator coil is under a lower pressure (due to  
the suction created by the compressor) than the liquid line,  
the liquid refrigerant leaves the metering device entering

SEALED REFRIGERATION SYSTEM  
REPAIRS  
The following procedure applies when replacing com-  
ponents in the sealed refrigeration circuit or repairing  
refrigerant leaks. (Compressor, condenser, evaporator,  
capillary tube, refrigerant leaks, etc.)  
EQUIPMENT REQUIRED:  
1. Voltmeter  
1. Recover the refrigerant from the system at the pro-  
cess tube located on the high side of the system by  
installing a line tap on the process tube.Apply gauge  
from process tube to EPA approved gauges from  
process tube to EPA approved recovery system.  
Recover CFCs in system to at least 5%.  
2. Ammeter  
3. Ohmmeter  
4. Vacuum Pump (capable of 200 microns or less  
vacuum.)  
5. Acetylene Welder  
2. Cut the process tube below pinch off on the suction  
side of the compressor.  
6. Electronic Halogen Leak Detector (G.E. Type H-6 or  
equivalent.)  
3. Connect the line from the nitrogen tank to the suction  
process tube.  
7. Accurate refrigerant charge measuring device such  
as:  
4. Drift dry nitrogen through the system and unsolder  
the more distant connection rst. (Filter drier, high  
side process tube, etc.)  
a. Balance Scales - 1/2 oz. accuracy  
b. Charging Board - 1/2 oz. accuracy  
8. High Pressure Gauge - (0 - 400 lbs.)  
9. Low Pressure Gauge - (30 - 150 lbs.)  
10. Vacuum Gauge - (0 - 1000 microns)  
5. Replace inoperative component, and always install a  
new lter drier. Drift dry nitrogen through the system  
when making these connections.  
6. Pressurize system to 30 PSIG with proper refrigerant  
and boost refrigerant pressure to 150 PSIG with dry  
nitrogen.  
EQUIPMENT MUST BE CAPABLE OF:  
1. Evacuation from both the high side and low side of  
the system simultaneously.  
7. Leak test complete system with electric halogen leak  
detector, correcting any leaks found.  
2. Introducing refrigerant charge into high side of the  
system.  
8. Reduce the system to zero gauge pressure.  
9. Connect vacuum pump to high side and low side of  
system with deep vacuum hoses, or copper tubing.  
(Do not use regular hoses.)  
3. Accurately weighing the refrigerant charge actually  
introduced into the system.  
4. Facilities for owing nitrogen through refrigeration  
tubing during all brazing processes.  
12  
10. Evacuate system to maximum absolute holding pres-  
sure of 200 microns or less. NOTE: This process can  
be speeded up by use of heat lamps, or by breaking  
the vacuum with refrigerant or dry nitrogen at 5,000  
microns. Pressure system to 5 PSIG and leave in  
system a minimum of 10 minutes. Release refriger-  
ant, and proceed with evacuation of a pressure of  
200 microns or less.  
ROTARY COMPRESSOR SPECIAL  
TROUBLESHOOTING AND SERVICE  
Basically, troubleshooting and servicing rotary compres-  
sors is the same as on the reciprocating compressor with  
only a few exceptions.  
1. Because of the spinning motion of the rotary, the  
mounts are critical. If vibration is present, check the  
mounts carefully.  
11. Break vacuum by charging system from the high side  
with the correct amount of refrigerant specied. This  
will prevent boiling the oil out of the crankcase.  
2. The electrical terminals on the rotary are in a differ-  
ent order than the reciprocating compressors. The  
terminal markings are on the cover gasket. Use your  
wiring diagram to insure correct connections.  
NOTE: If the entire charge will not enter the high  
side, allow the remainder to enter the low side in  
small increments while operating the unit.  
REFRIGERANT CHARGE  
12. Restart unit several times after allowing pressures  
to stabilize. Pinch off process tubes, cut and solder  
the ends. Remove pinch off tool, and leak check the  
process tube ends.  
1. The refrigerant charge is extremely critical. Mea-  
sure charge carefully - as exact as possible to the  
nameplate charge.  
2. The correct method for charging the rotary is to  
introduce liquid refrigerant into the high side of the  
system with the unit off. Then start compressor and  
enter the balance of the charge, gas only, into the  
low side.  
SPECIAL PROCEDURE IN THE CASE OF MOTOR  
COMPRESSOR BURNOUT  
1. Recover all refrigerant and oil from the system.  
2. Remove compressor, capillary tube and lter drier  
The introduction of liquid into the low side, without  
the use of a capillary tube, will cause damage to  
the discharge valve of the rotary compressor.  
from the system.  
3. Flush evaporator condenser and all connecting  
tubing with dry nitrogen or equivalent, to remove  
all contamination from system. Inspect suction and  
discharge line for carbon deposits. Remove and  
clean if necessary.  
NOTE: All inoperative compressors returned to  
Friedrich must have all lines properly plugged with  
the plugs from the replacement compressor.  
4. Reassemble the system, including new drier strainer  
and capillary tube.  
5. Proceed with processing as outlined under hermetic  
component replacement.
