5.3. Final check and test run

5.3.1.

Final check

Before switching on the unit, read the following recommendations:
When the complete installation and all necessary settings have
been carried out, be sure that all panels of the unit are closed. If
this is not the case, inserting your hand through the remaining
openings can cause serious injury due to electrical and hot parts
inside the unit.
The service panel of the switch box may only be opened by a
licensed electrician for maintenance purposes.
DANGER
Never leave the unit unattended during installation or
servicing. When the service panel is removed live parts
can be easily touched by accident.
INFORMATION
Note that during the first running period of the unit,
required power input may be higher than stated on the
nameplate of the unit. This phenomenon originates from
the compressor that needs elapse of a 48 hours run in
period before reaching smooth operation and stable power
consumption.
