Refrigeration Service Operations 11-4
Condenser Coil
Removal
1. Recover the refrigerant charge.
2. Drain engine coolant from the expansion tank.
• SL and SLe: Unbolt and remove coolant expansion tank from condenser coil frame. Unsolder tank breather tube.
• SLX (with copper tube and fin): Drain all coolant. Remove coolant hoses from radiator portion of the coil.
3. Unsolder the refrigerant line connections.
4. Unbolt and remove the condenser coil.
NOTE: For Micro Channel Coil, please follow points 1, 2 and 4 above. (Radiator can be left in for this one)
Installation
1. Clean the refrigerant tubes for soldering.
2. Place the condenser coil in the unit and install the mounting hardware.
3. Solder the refrigerant line connections.
4. Change drier.
5. SLX copper tube and fin condenser - refit coolant hoses to radiator portion of coil.
6. Pressurise the refrigeration system and test for leaks. If no leaks are found, evacuate the system.
7. Fill tank half way with 50/50 antifreeze of correct specification for the system.
• SL and SLe: Install clamps on the condenser inlet line. Install engine coolant expansion tank. Solder tank breather tube.
8. After evacuation, charge the unit with refrigerant.
9. Operate unit and check compressor oil level and refrigerant charge.
• Check and add correct coolant solution to fill the cooling system to the top of the filler neck if required. Make sure there
are no low spots in the vent tube that will trap air in the expansion tank.
• SLX, SLXe and SLXi , make sure that tank is half full
• SLX copper tube and fin: Refill cooling system (refer to correct system refill procedure in Engine Maintenance Chapter of
this manual)
Discharge Vibrasorber
Removal
1. Recover the refrigerant charge.
2. Heat the connections on the vibrasorber until the vibrasorber can be removed.
CAUTION: Use a heat sink or wrap the vibrasorber with wet rags to protect the vibrasorber.
Installation
1. Prepare the vibrasorber and tubing fittings by cleaning thoroughly.
2. Solder the vibrasorber connections.
3. Change drier
CAUTION: Use a heat sink or wrap the vibrasorber with wet rags to protect the vibrasorber.
4. Pressurise the system and test for leaks. If no leaks are found, evacuate the system.
5. Charge the unit with correct refrigerant and check the compressor oil level.
NOTE: SLX, SLXe and SLXi => refer to correct refrigerant charging procedure
Suction Vibrasorber
NOTE: If there ia a possibility that the unit has been in a vacuum owing to a leak to the vibraabsorber, the refrigerant must
be recovered.
Removal
1. Pump down the low side and equalise pressure to 0 psig, (0 bar g).
2. Unsolder the suction vibrasorber from the suction service valve. Unsolder the connection to the accumulator and remove from
the unit.
