• Comply with national gas regulations.
• After installation work, make sure below before operation.
- Connection pipes are connected properly and no leakage.
- Packed valves are fully open.
Running compressor without open packed valves may cause abnormal high
pressure and parts failure.
Leakage at connection piping may suck air and make further high pressure

• During pump down work make sure below process.
- Don’t mix air into the refrigerant cycle.
- Stop the compressor before removing piping after packed valves are
fully closed.
