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.
