ELECTRIC PREHEATER 19
As an option, the ventilation unit can be implemented with an electric
preheater. Types
LE(H)
are already equipped with an electric preheating
element as standard. This ensures that the heat exchanger does not freeze up
at low outdoor temperatures. As a result, the ventilation unit will continue to
function optimally in freezing temperatures.
MOUNTING AND ELECTRICAL CONNECTION OF THE PREHEATER
An internal location is provided for the preheater, see picture below. In this
way the preheater will warm up the air from outdoors, if necessary, in order to
prevent the heat exchanger from freezing up.
• Remove the filter flap
• Unscrew the door panel
The cable of the electric preheater must be brought through the slot provided
for this to the circuit board and connected according to the following electrical
diagram.
The electric preheater manual can be consulted for a detailed installation.
