1.
Clean the tubes for soldering.
2.
Remove the coil from the modulation valve.
3.
Properly position the modulation valve, the tube, and
the elbow between the evaporator outlet and the heat
exchanger inlet.
4.
Install the suction line assembly clamps.
5.
Solder the suction line assembly connections.
CAUTION: Use a heat sink or wrap the valve
with wet rags to prevent damaging the valve.
6.
Connect the Thermax-V expansion valve line to the
suction line.
7.
Pressurize the low side and test for leaks. If no leaks are
found, evacuate the low side.
8.
Clean suction tube to bright polished condition. Install
the feeler bulb clamps and feeler bulbs on the side of
the suction line in their former positions. The feeler
bulbs must make good contact with the suction line or
operation will be faulty. Wrap with insulating tape.
9.
Install the coil on the modulation valve and connect the
wires.
10. Install the fan module, the fan belt, and both idler pul-
leys. Tighten the fan belt to the proper tension, and
install the grille.
11. Open the refrigeration valves and place the unit in oper-

HOT GAS SOLENOID VALVE
Removal
1.
Recover the refrigerant charge.
2.
Disconnect the wires and remove the coil from the
valve.
3.
Unsolder the lines and remove the valve.
Installation
1.
Clean the tubes for soldering.
2.
Remove the coil and place the valve in position.
3.
Solder the inlet and outlet connections. After the valve
cools, install the coil and connect the wires.
4.
Pressurize the refrigeration system and test for leaks.
5.
If no leaks are found, evacuate the system.
6.
Recharge the unit with proper refrigerant and check the
compressor oil.
LIQUID LINE CHECK VALVE REPAIR
Removal
1.
Pump down the low side and then equalize pressure to
slightly positive.
