The distance from the sheet metal casing of the air heater to wood or other combustible

9.1.1 Heating coil electric, (ELEE) in unit, (ESET-VK) in duct
The air heater is adapted for assembly in duct systems and requires separate connection.
The air flow direction through the air heater must correspond with the direction arrow on the
air heater.
The heater can be connected in horizontal or vertical ducts with the connection box to the
side.
The distance from the air heater to duct elbows, dampers, filters or the like, should be at least
the distance corresponding to the diagonal measurement of the heater (from corner to corner
in the heater’s duct section). If the distance is smaller, the air stream through the heater can
become uneven and the overheat protection can be tripped.
The air heater is insulated according to the applicable rules for ventilation ducts/ventilation
units and with non-combustible insulating material. The type plate and warning plate must
be fully visible and the cover must be possible to open. The air heater must be accessible for
replacement and servicing.

The trim heater is integrated into EcoCooler and ThermoCooler HP and is normally already
fitted on delivery. It can be lifted out to facilitate cleaning and maintenance. See instruction in
