Routine maintenance is required annually or semi-annually, depending upon annual usage.

1. Clean the unit air intake ﬁ 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 ﬁ 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 ﬁ n pack. Use a sweeping up and down motion in the direction of the vertical aluminum ﬁ 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 electr ical tests. Use an air conditioning or refrigeration ther mometer to chec k room, outdoo r 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.

REFRIGERATION SYSTEM SEQUENCE OF OPERATION

A good understanding of the basic operation of the refrigeration system is essential for the service technician. Without this understanding, accurate troubleshooting of refrigeration system problems will be more difﬁ cult and time consu ming, if not (in some cases) entirely impossible. The refrigeration system uses four basic principles (laws) in its operation they are as follows:

1. “ Heat always flows from a warmer body to a cooler body . ”

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.”

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 pres sure 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) T emperature .

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 ﬁ nned surface facilitates the transfer of heat from the refr igerant to the relatively cooler outdoor air.

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 ﬁ 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.

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 ﬂ ow across the evaporator coil .

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, howev er, the refrigerant must be totally evaporated (changed) to a gas before leav ing the evaporator coil .

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.

Refrigerant System Components

When a sufﬁ cient 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 ﬂ ow across the condenser coil.

The RAC design determines at exactly w hat 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.

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.

The liquid refrigerant next enters the metering device. The

metering device is a capillary tube. The pur pose of the metering device is to “meter” (i.e. control or measure ) the quantity of refrigerant entering the evaporator coil.

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.

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 INSTALLA TION OF A SUCTION LINE DRIER.

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

EQUIPMENT REQUIRED:

1. Voltmeter

2. Ammeter

3. Ohmmeter

4. Vacuum Pump (capable of 200 microns or less vacuum.)

5. Acetylene Welder

6. Electronic Halogen Leak Detector (G.E. T ype H-6 or equivalent.)

7. Accurate refrigerant charge measuring device such as:

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)

EQUIPMENT MUST BE CAPABLE OF:

HERMETIC COMPONENT REPLACEMENT

The following procedure applies when replacing components in the sealed refrigeration circuit or repairing refrigerant leaks. (Compressor, condenser, evaporator, capillary tube, refrigerant leaks, etc.)

1. Recover the refrigerant from the system at the process 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. Cut the process tube below pinch off on the suction side of the compressor.

3. Connect the line from the nitrogen tank to the suction process tube.

4. Drift dry nitrogen through the system and unsolder the more distant connection ﬁ rst. (Filter drier, high side process tube, etc.)

5. Replace inoperative component, and always install a new ﬁ 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.

1. Evacuation from both the high side and low side of the system simultaneously.

2. Introducing refrigerant charge into high side of the system.

3. Accurately weighing the refrigerant charge actually introduced into the system.

4. Facilities for ﬂ owing nitrogen through refrigeration tubing during all brazing processes.

7. Leak test complete system with electric halogen leak detector, correcting any leaks found.

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.)

10. Evacuate system to maximum absolute holding pressure 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 refrigerant, and proceed with evacuation of a pressure of 200 microns or less.

1 1. Break vacuum by charging system from the high side

with the correct amount of refrigerant speciﬁ ed. This will prevent boiling the oil out of the crankcase.

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.

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.

SPECIAL PROCEDURE IN THE CASE OF MOTOR COMPRESSOR BURNOUT

1. Recover all refrigerant and oil from the system.

2. Remove compressor, capillary tube and ﬁ lter drier 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.

ROTARY COMPRESSOR SPECIAL TROUBLESHOOTING AND SERVICE

Basically, troubleshooting and servicing rotary compressors 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.

2. The electrical terminals on the rotary are in a different order than the reciprocating compressors. The terminal markings are on the cover gasket. Use your wiring diagram to insure correct connections.

REFRIGERANT CHARGE

1. The refrigerant charge is extremely critical. Measure 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.

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.

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.
