Do not install the outdoor unit in pits or air vents
Installing the pipes
Use suitable connecting pipes and equipment for
the refrigerant R410A.
Wrap all the refrigerant pipes and joints.
Tighten the connections using two wrenches wor-
king 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.

Condensation is produced and flows from the out-
door unit when the appliance is operating in the
heating mode. In order not to disturb neighbours
and to respect the environment,install a drain fitting
and a drain hose to channel the condensate water.
Install the drain fitting and rubber washer on the
