CAUTION
1. Use the pressure indicating function
of the controller to check the working
pressure as much as possible
instead of using the gauge manifold
in order to prevent foreign particles
or moisture from mixing into the
refrigerant system.
2. Do not use any of the pressure gauge,
gauge manifold, charge hose and
charging cylinder which have been
used for CFC12 in order to prevent
refrigerant or refrigerant oil of a
different kind from mixing.
Use the exclusive tools for HFC
134a.
The service port of quick joint type is
provided to make improved handling.
