A pre-heater (from third parties) may be used; the
installer is entirely responsible for its installation and
operation. The parameters required when choosing the
pre-heater are as follows:
- airflow at minimum speed: 50 m3/h@100 Pa;
- airflow at maximum speed: 110 m3/h@100 Pa;
- maximum air temperature at inlet: 50°C;
- pre-heater minimum distance: 500 mm.
Level one thermostat cut-in threshold: 50°C.
Level two thermostat cut-in threshold: 70°C.
Maintenance/Cleaning
Before commencing any operation, make sure that the
appliance is disconnected from the power supply and
the blades have stopped turning. Dismantling and
assembly are special maintenance operations and must
be carried out by qualified personnel only.

Recommended maintenance intervals:
Filter inspection: every 50/60 days;
Filter replacement: from 4 to 6 months depending upon
the degree of pollution in the surrounding atmosphere
(dust, fumes etc).
NOTE
Failing to clean or replace filters has a significant effect
on the efficiency of the system with:
- increased loss of pressure in the air circulation system
and reduced airflow;
- subsequent drop in system performance and comfort
levels.
NOTE
During replacement procedures, pay attention to the
direction of the arrows on the filters (fig.5).
