PRECAUTIONS FOR REFRIGERANT CONNECTION
HA-18prose procedureWARNING
Gradually loosen discharge side hose fitting, and remove it after remaining pressure has been released.
CAUTION
When replacing or cleaning refrigerant cycle components, observe the following.
Do not leave compressor on its side or upside down for more than 10 minutes, as compressor oil will enter low pressure chamber.
IMPORTANT
When connecting tubes, always use a torque wrench.
After disconnecting tubes, plug all openings immediately to prevent entrance of dirt and moisture.
Always replace used O-rings.
When connecting tube, apply compressor oil to portions shown in illustration. Be careful not to apply oil to threaded portion.
O-ring must be closely attached to inflated portion of tube.
After inserting tube into union until O-ring is no longer visible, tighten nut to specified torque.
After connecting line, conduct leak test and make sure that there is no leakage from connections. When the gas leaking point is found, disconnect that line and replace the O-ring. Then tighten connections of seal seat to the specified torque.
