ROUTINE MAINTENANCE

NOTE: Units are to be inspected and serviced by qualifi ed service personnel only.

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 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.

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 consuming,
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 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 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 refrigerant 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, however, the refrigerant must
be totally evaporated (changed) to a gas before leaving
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 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.

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 purpose 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.

SEALED REFRIGERATION SYSTEM REPAIRS

IMPORTANT

ANY SEALED SYSTEM REPAIRS TO COOL-ONLY
MODELS REQUIRE THE INSTALLATION OF A
LI QU ID LINE DR IER. ALSO, A NY SE AL ED SYSTE M
REPAIRS TO HEAT PUMP MODELS REQUIRE THE
INSTALLATION 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. Type 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.)

12

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.

11. 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.
