OUTDOOR UNIT INSTALLATION
1.
Fit the drainage outlet and drainage hose (only for models with a
heat pump).
Condensation will drip off the outdoor unit when the indoor unit
is operating in Heating mode. Fit a drainage outlet and a drainage
hose in order to drain the water effectively. Fit the drainage outlet
and rubber washer to the base plate of the outdoor unit (see fig.).
2.
Installing and fitting the outdoor unit
Bolt the unit to a level and solid base.
Ensure that the unit is mounted securely in order to prevent problems caused by strong wind and
vibrations.
3.
Connecting the outdoor unit pipes
Remove the covers of the two-way and three-way valve.
Close the pipes separately with the appropriate tightening moment.
4.
Outdoor unit cable connection (see previous page)
Purging the pipe system
Air and moisture that remain in the pipe system after installation can damage the compressor. After the
indoor and outdoor units have been connected, air and moisture must be removed with the aid of a vacuum
pump (see below).
