Charging Process - Whirlpool R600A Service Manual

case) to the extraction valve (the other end should be
tightly connected to the one-way valve attached to
charging case).
Sealed System Evacuation
Due to the narrow charging tolerances associated with
R600a refrigerant, it is necessary to draw a deep vacuum of
at least 28" of vacuum to ensure proper evacuation. Oil in
the vacuum pump should be changed frequently to ensure
the ability to draw a deep vacuum.
¾ For evacuation connect both sides Low and high -
Connect a hose to gauge manifolds side port and the
opposite end to the upper brass-T.
¾ Connect an additional charge hose to a Gauge manifold
lower male port and the other hose end to the 2nd
quick disconnect adapter. Unclip and thread the quick
disconnect adapter cap onto the high side charge port,
DO NOT CONNECT QUICK DISCONNECT TO THE ADAPTER
CAP THAT IS ON THE PRODUCT AT THIS TIME.
