CAUTION
To prevent trapping liquid refrigerant in the service valve after charging, perform the following steps while the compressor is ON and before disconnecting the manifold gauge set:
SBackseat applicable discharge or manual liquid line valve.
SMidseat manifold gauge set hand valves.
SAllow the gauge set to pull down to suction pressure.
b. Removing the Manifold Gauge Set
1.While the compressor is still ON, backseat the discharge service valve.
2.Midseat both hand valves on the manifold gauge set and allow the pressure in the manifold gauge set to be drawn down to suction pressure. This enables the liquid that condensed in the high side hose to be returned to the system.
3.Backseat the suction service valve. Backseat both field service couplings, and remove the couplings from the service ports.
4.Install both service valve stem caps and service port caps
