Refrigeration Service Operations
86
Installation
1. Place the evaporator coil in the evaporator
housing and install the mounting bolts.
2. Solder the hot gas line and suction line
connections to the evaporator coil.
NOTE: Replace any other refrigeration tubes
that were removed.
3. Solder the distributor to the expansion valve.
4. Replace and connect the sensors.
5. Pressurize the low side and test for leaks. If no
leaks are found, evacuate the low side.
6. Clean the suction line to a bright polished
condition. Install the feeler bulb on the side of
the suction line in its former position. The
feeler bulb must make good contact with the
suction line or operation will be faulty. Wrap
with insulating tape.
7. Replace the upper and lower evaporator
access panels.
8. Open the refrigeration valves and place the
unit in operation. Check the refrigerant charge
and compressor oil. Add as required.
Accumulator
Removal
1. Pump down the low side and equalize the
pressure to slightly positive.
2. Unsolder the inlet and outlet suction lines
from the accumulator.
3. Unbolt and remove the accumulator from the
unit.
Installation
1. Place the accumulator in the unit and tighten
the mounting bolts and nuts.
2. Solder the inlet and outlet suction lines to the
accumulator.
3. Pressurize the low side and test for refrigerant
leaks. If no leaks are found, evacuate the low
side.
4. Open the refrigeration valves and place the
unit in operation. Check the refrigerant charge
and the compressor oil, and add as required.
Suction Vibrasorber
Removal
1. Pump down the low side and equalize the
pressure to slightly positive.
2. Unsolder the suction vibrasorber from the
suction service valve.
3. Unsolder the connection to the accumulator
and remove the vibrasorber from the unit.
Installation
1. Prepare the suction vibrasorber and tube
fittings for soldering by cleaning thoroughly.
2. Solder the vibrasorber to the suction service
valve.
3. Solder the suction hose connection to the
accumulator.
4. Pressurize the low side and check for leaks. If
no leaks are found, evacuate the system.
5. Open the refrigeration valves and place the
unit in operation. Check the refrigerant charge
and the compressor oil, and add as required.
CAUTION: Use a heat sink or wrap
vibrasorber with wet rags to prevent
damaging the vibrasorber.
