Wrap with straps all refrigerant pipes
and joints.
Tighten connections using two keys
operated in opposite directions.
Vacuum pump
Humid air left inside the refrigerant circuit can cause com-
pressor malfunction. After having connected the indoor
and outdoor units, bleed the air and humidity from the
refrigerant circuit using a vacuum pump.
(1) Unscrew and remove the caps from the 2-way and 3-
way valves.
(2) Unscrew and remove the cap from the service valve.
(3) Connect the vacuum pump hose to the service valve.
(4) Operate the vacuum pump for 10-15 minutes until an
absolute vacuum of 10 mm Hg has been reached.
(5) With the vacuum pump still in operation, close the
low-pressure knob on the vacuum pump coupling.
Stop the vacuum pump.
(6) Open the 2-way valve by 1/4 turn and then close it
after 10 seconds. Check all the joints for leaks using
liquid soap or an electronic leak device.
(7) Turn the body of the 2-way and 3-way valves. Discon-
nect the vacuum pump hose.
(8) Replace and tighten all the caps on the valves.

Additional charge of refrigerant and oil
If the length of the connecting pipe is
increased by 10 m compared to the
standard length, add 5 ml of refrigerant
oil for every 5 m of pipe added.
Method for calculating the amount of
additional refrigerant charge (liquid pipe):
amount of additional refrigerant charge =
additional length of pipe liquid x amount
of additional refrigerant charge per meter.
