WHEN INLET CYLINDER IS EMPTY
The 750-SP1 will recover and recycle refrigerant from the Inlet Cylinder until it is empty. When all
of the refrigerant has been recovered and recycled, the COMPRESSOR-ON light will be off and
the 750-SP1 will automatically shut off.
Oil which has been removed from the refrigerant must be drained from the 750-SP1 as follows.
This procedure MUST be performed after emptying each Inlet Cylinder.
1. Set Main Switch to OFF.
2. Press and hold the Purge Button (Right side of machine) until the pressure on the Pressure
Gauge above the Purge Button drops one small graduation mark (approximately 5 PSIG).
3. SLOWLY open Oil Drain Valve (Lower left side on rear of machine) and drain any oil which
may have been removed from the refrigerant. A plastic cup is provided to collect the oil.
4. Close the Oil Drain Valve.
