INSTALLING THE OUTDOOR UNIT

Location

Use bolts to secure the unit to a flat, solid floor.

When mounting the unit on a wall or the roof, make

sure the support is firmly secured so that it cannot

move in the event of intense vibrations or a strong

wind.

Do not install the outdoor unit in pits or air vents

Installing the pipes

Use suitable connecting pipes and equipment for the

refrigerant in the appliance (see rating plate).

The refrigerant pipes must not exceed the maximum

lengths given in the technical data table.

Lag all the refrigerant pipes and joints.

Tighten the connections using two wrenches working

in opposite directions.

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 conden-

sate 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.

Do not install the outdoor unit where it is exposed

to sunlight.

Ensure that the recommended space is left around

the appliance.
