following steps while the compressor is ON
and before disconnecting the manifold
gauge set:
S Backseat applicable discharge or manual
liquid line valve.
S Midseat manifold gauge set hand valves.
S Allow 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 bothhand valveson themanifoldgaugeset
and allow the pressure in the manifold gauge set to
bedrawndown to suction pressure.This enablesthe
liquid that condensed in the high side hose to be
returned to the system.
