Fill the gap at the site
Make sure to seal-off the space around
areas where the wires and refrigerant
pipes enter the unit to ensure that small
animals, rainwater, or snow cannot enter
the unit through such openings and cause
damage to the unit.
Caution:
Make sure to seal-off the openings for the pipe and wire retrieval.
•
Small animals, rainwater, or snow entering through the openings may
cause damage to the device.
•
After evacuation and refrigerant charging, ensure that the handle is fully open.
If operating with the valve closed, abnormal pressure will be imparted to the
high- or low-pressure side of the refrigerant circuit, giving damage to the com-
pressor, four-way valve, etc.
•
Determine the amount of additional refrigerant charge by using the formula,
and charge refrigerant additionally through the service port after completing
piping connection work.
•
After completing work, tighten the service port and cap securely so as not to
generate any gas leakage. (Refer to the table on the below for appropriate
tightening torque.)

Caution:
•
Keep the valve closed until refrigerant charging to the pipes to be added
on site has been completed. Opening the valve before charging the re-
frigerant may cause damage to the unit.
•
Do not use a leak detection additive.
