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/ball valve. (The stop/ball valve will not work in its initial state fresh out of the factory (totally closed with cap on).)

Connect the gauge manifold valve and the vacuum pump to the service port of the stop/ball valve .

Run the vacuum pump. (Vacuumize for more than 15 minutes.)

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

Leave as it is for one or two minutes. Make sure the pointer of the gauge manifold valve remains in the same position. Confirm that the pressure gauge show-0.1MPa(-79cmHg)

Remove the gauge manifold valve quickly from the service port of the stop/ball valve.

After refrigerant pipes are connected and evacuated, fully open all stop/ball 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.
