3. Remove the condenser coil mounting bolts.
Remove the mounting clamps from the
condenser inlet line.
4. Unsolder the inlet line and liquid line
connections. Lift the coil from the unit.
Installation
1. Clean the fittings for soldering.
2. Place the coil in the unit and install the
mounting bolts.
3. Solder the inlet line and liquid line
connections.
4. Pressurize the refrigeration system and test for
leaks. If no leaks are found, evacuate the
system.
5. Install the clamps on the condenser inlet line.
6. Install the engine coolant expansion tank and
refill half way with engine coolant.
7. Recharge the unit with proper refrigerant and
check the compressor oil.
Discharge Vibrasorber
Removal
1. Recover the refrigerant charge.
2. Heat the connections on the vibrasorber until
the vibrasorber can be removed.
Installation
1. Prepare the vibrasorber and tubing fittings by
cleaning thoroughly.
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 Check Valves
This unit uses some in-line check valves. An
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.
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
NOTE: 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.
CAUTION: Use a heat sink, P/N 204-584
or wrap the vibrasorber with wet rags to
prevent damaging the vibrasorber.
