Section 6 Sealed System
6-8
Evaporator and Suction Line Replacement
1. Disconnect electrical supply to unit.
2. Disassemble the product enough to get access to the
compressor (refer to Component Removal Section).
3. Attach an approved self tapping line tap valve to the
process tube. Connect refrigerant recovery system
to tap valve. Turn on recovery system, open the
line tap valve, and allow refrigerant to flow into an
approved tank.
4. Remove evaporator from its installation position.
5. Clean suction and capillary lines with abrasive cloth.
Connect lines to replacement evaporator and solder
joints.
6. Install evaporator assembly in air conditioner.
7. Install filter-drier between condenser outlet and the
capillary tube connection.
8. Evacuate and charge system using recommended
procedure described under Evacuating and
Recharging, then reassemble unit.
Condenser Replacement
1. Disconnect electrical supply to unit.
2. Disassemble the product enough to get access to the
compressor (refer to Component Removal Section).
3. Attach an approved self tapping line tap valve to the
process tube. Connect refrigerant recovery system
to tap valve. Turn on recovery system, open the
line tap valve, and allow refrigerant to flow into an
approved tank.
4. After refrigerant is completely recovered, disconnect
inlet and discharge lines from condenser.
5. Remove condenser.
6. Install replacement condenser.
7. Install filter-drier between condenser outlet and the
capillary tube connection.
8. Evacuate and charge system using recommended
procedure described under Evacuating and
Recharging, then reassemble unit.
Final Leak Test
1. With the refrigerator turned OFF leak test all
low-side system components.
2. Turn unit ON and run until the condenser is warm.
Leak test the high-side system components.
Air Conditioner Air Temperatures
Temperatures are affected by frost accumulation on the
evaporator, service load, ambient temperature, percent
of relative humidity, thermostat calibration (cut-in and
cut-out), and by compressor efficiency.
Line Voltage
It is essential to know the line voltage at the product.
A voltage reading should be taken at the instant the
compressor starts, and also while the compressor is
running. Line voltage fluctuation should not exceed 10%
plus or minus, from nominal rating. Low voltage will
cause overheating of the compressor motor windings,
resulting in compressor cycling on thermal overload, or
the compressor may fail to start. Inadequate line wire
size, and overloaded lines, are common reasons for low
voltage at the product.
