Installing the pipes

Install the drain fitting and the drain hose (for model with heat pump only)

Condensation is produced and flows from the outdoor 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 outdoor unit chassis

and connect a drain hose to it as shown in the figure.

Use suitable connecting pipes and equipment for the refrigerant R410a.

The connecting pipes must not exceed the maximum lengths 10 m.

Wrap all the refrigerant pipes and joints.

Tighten the connections using two wrenches working in opposite directions.

INSTALLATION DIMENSION DIAGRAM

• Contact service centre before installation to avoid the malfunction due to unprofessional installation.

• When picking up and moving the units, you must be guided by trained and qualified person.

• Ensure that the recommended space is left around the appliance.

compressor malfunction. After having connected the indoor and

outdoor units, bleed the air and humidity from the refrigerant

circuit using a vacuum pump.

valves.

Unscrew and remove the cap from the service valve.

Operate the vacuum pump for 10-15 minutes until an

absolute vacuum of 10 mm Hg has been reached.

With the vacuum pump still in operation, close the low-

pressure knob on the vacuum pump coupling. Stop the

vacuum pump.

Open the 2-way valve by 1/4 turn and then close it after
