General Service

Use care when disconnecting or connecting refrigerant lines; always use a back-up wrench and be careful not to over-tighten any connection. Over-tightening will result inline and flare seat distortion and a system leak.

When making pressure checks on systems having service valves, be sure valve is in the intermediate position. If turned in too far, the hose connection will be closed, a position used for isolating the compressor. When closing the gauge port, do not over-tighten the valve or damage to the seat will result.

After disconnecting gauge lines, check the valve areas to be sure service valves are correctly seated and Schrader valves, if used, are not leaking.
