EVACUATION PROCEDURES

Connect the refrigerant pipes (both the liquid and gas
pipes) between the indoor and the outdoor units.

Remove the service port  cap  of the stop valve on the

 side

 of

 the

outdoor unit gas pipe. (The stop

 valve

 will

 not

 work

 in

 its

 initial

state fresh out of the factory (totally closed with cap on).

Connect the gage manifold valve and the vacuum  pump  to  the service  port of the stop valve on
 the

 gas

  pipe side of the outdoor unit.

Run the vacuum pump for more than 15 minutes and at this time confirm that the pressure gage
 indicates -0.1 Mpa (-76 cmHg).

Check the vacuum with the gage manifold valve, then  close  the  gage  manifold valve, and stop the
vacuum pump.

Leave it as is for one or two minutes .Make sure the pointer of the gage manifold valve remains
 in the same position.

Remove the gage  manifold  valve quickly  from the  service port  of  the stop valve.

After refrigerant pipes are connected and evacuated, fully open all stop valves
on gas and liquid pipe sides.
Operating without fully opening lowers the performance and causes trouble.

Pipe length
7m maximum
No gas charge is
needed.

Pipe length
exceeding 7m
Charge the prescribed
amount of gas.

Tighten the cap to the service port to obtain the initial status.

Retighten the cap.
