Vacuuming
Air and humidity left inside the refrigerant
circuit can cause compressor malfunction.
After having connected the indoor
and outdoor units, remove the air
and humidity from the refrigerant
Circuit by using a vacuum pump.
Note Only persons or companies qualified
and experienced in the installation, service
and repair of refrigerant products should
be permitted to do so. The purchaser must
Ensure that the person and/or company
who is to install, service or repair this
Air conditioner has qualifications

from the connected pipe and cooling unit.
If this is not done, the discharge pressure
will rise abnormally and may damage the
refrigerating-cycle unit.

pipe side service valve.
Fully open the LO knob of the manifold
valve and energize both solenoid valves.
Run the vacuum pump.

Remove the valve cap from the spindle
of the service valve.
