7 USE AND OPERATION
Use the electric heater just for heating air. For
example, use the electric heater for heating or
drying houses, buildings, site offices and
workshops. You can also use the electric
heater for speeding up drying processes of,
for example, paintwork and plasterwork.
Advice
The best and quickest drying result is
achieved when you install the electric heater
below and open a window above.

8 MAINTENANCE
Before starting the maintenance
activities, disconnect the power
supply.
Remove the rear panel from the electric
heater by unscrewing all screws.
Clean the inside of the electric heater with
compressed air. Make sure that the fan
blade is cleaned well.
Carefully loosen very persistent dirt with a
screwdriver. Make sure that everything is
removed, otherwise the ventilator can get
out of balance. This will cause vibrations
that will seriously affect the life span of the
bearings.
Never clean the inside with water.
Clean the housing with a moist cloth. After
that let the housing dry or wipe it dry. Place
the housing on the electric heater again.
Touch up any damage of the coating.
We constantly aim at improving our
