(2) Refrigerant Charging Hose
The charging hoses are classified into three colors. Each
charging hose must be handled as follows :
• The air conditioner manufacture recommends that the blue hose
(6) is used for the LO pressure side (suction side), the green
hose (5) for refrigeration side (center connecting port) and the red
hose (3) for
HI pressure side (discharged side).
(When connecting)
• Push the quick disconnect adaptor (4) into the charging valve,
and push on part A until a click is heard.
NOTE
Q
• When connecting, push carefully so the pipe does not bend.
• When connecting the quick disconnect connector, should
the sleeve (7) move before the quick link connector can be
connected to the charging valve, move the quick sleeve to
its original position and try again.
• When some refrigerant remains in the charging hose at the
time of connections, it may be difficult to connect the quick
link connector. In this case, perform the operation after
removing any residual pressure in the hose. (Remove the
residual pressure by pushing the pusher (8).)
(When reassembling)
• While holding on to part A of the quick disconnect adaptor, slide
part B up.
NOTE
Q
• After removing the adaptor, ensure to cap the quick
disconnect adaptor service valve.
