Installation
1. Lift the compressor into the unit and install the mounting bolts.
2. Clean tubes for soldering. Solder discharge line to compressor.
3. Install the suction valve using a new gasket soaked in refrigerant oil.
4. Solder the liquid injection tube to injection fitting.
NOTE: Use a heat sink or wrap the injection fitting with wet rags before soldering the connection to prevent damage to the
O-ring in the fitting.
5. Pressurise the system and test for refrigerant leaks.
6. If no leaks are found, evacuate the system. Replace the compressor/electric motor belt and adjust the tension.
7. Charge the unit with refrigerant.
8. Operate the unit at least 30 minutes and then inspect the oil level in the compressor. Add or remove oil if necessary.
9. Check the refrigerant charge and add refrigerant if needed.
