2. Solder the vibrasorber connections.
3. Pressurize the system and test for leaks. If no leaks
are found, evacuate the system.
4. Charge the unit with the proper refrigerant and
check the compressor oil level.
In-Line Condenser Check Valve
This unit uses an in-line condenser check valve. The in-
line check valve is not repairable and must be replaced
if it fails. A heat sink must be used on the in-line check
valve when it is being soldered in place to prevent
damage to the neoprene seal.

Condenser Check Valve
Replacement
Removal
1. Recover the refrigerant charge.
2. Place a heat sink on the check valve.
3. Unsolder the lines and remove the check valve.
Installation
N No otte e:: A heat sink must be used on the in-line check
valve when it is being soldered in place to
prevent damage to the neoprene seal.
1. Clean the tubes for soldering.
2. Place the check valve in position. The arrow on the
valve body indicates the direction of refrigerant
flow through the valve.
3. Place a heat sink on the check valve.
4. Solder the inlet and outlet connections.
5. Pressurize the refrigeration system and test for
leaks.
6. If no leaks are found, evacuate the system.
7. Recharge the unit with proper refrigerant and
check the compressor oil.
Bypass Check Valve
Removal
1. Pump down the low side and equalize the pressure
to slightly positive.
2. Close the bypass service valve.
3. Unsolder the bypass check valve line from the
bypass check valve. Use a heat sink on the bypass
check valve.
4. Unsolder and remove the bypass check valve from
the receiver tank. Use a heat sink on the bypass
check valve.
Installation
1. Solder the bypass check valve onto the receiver
tank. Use a heat sink on the bypass check valve.
2. Solder the bypass check valve line to the bypass
check valve. Use a heat sink on the bypass check
valve.
3. Pressurize the low side and test for leaks. If no
leaks are found, evacuate the system.
4. Open the suction service valve and the bypass
service valve and place the unit in operation.
Receiver Tank
Removal
1. Recover the refrigerant charge.
2. Unsolder the inlet, outlet, and bypass check valve
lines from the receiver tank. Use a heat sink on the
bypass check valve.
3. Unsolder and remove the bypass check valve from
the receiver tank. Use a heat sink on the bypass
check valve.
4. Remove the high pressure relief valve from the
receiver tank.
5. Unbolt the mounting brackets and remove the
receiver tank from the unit.
Installation
1. Install the high pressure relief valve in the receiver
