Be careful during any maintenance operation; you could get injured by
some metal parts; use protective gloves.
The units do not require any particular maintenance operation: only
the periodical cleaning of the air filter should be carried out.
It is necessary to carry out a running in period of 100 hours in order to
eliminate all mechanical friction.
The starting up must be carried out at the maximum speed.
For good operation of the units follow the instructions below:

! do not pour liquids into the unit;
! do not introduce metal parts through the air outlet grill.

Each time the machine is turned on after being idle for a long
period, ensure there is no air in the heat exchanger.
Before using the unit for air conditioning, check that:
! condensate drainage is performed correctly:
! the heat exchanger fins are not obstructed by deposits of dirt.
If necessary clean the fins with low pressure compressed air
or steam without damaging the fins.
