Electrical preheater – KWL-EVH 360 W
1 .9

Functional description

The electrical preheater is used to increase the intake air temperature and it prevents the heat exchanger from freezing
at very low intake temperatures! The electrical preheater is controlled gradually to reduce energy consumption.
The electrical preheater is equipped with two safety temperature limiters. The preheater has a two-stage safety tem-
perature limiter (Auto reset = trigger temp. +60 °C) (manual reset = trigger temp. +110 °C). The first limiter resets itself
automatically, and it is necessary to isolate the unit from the mains power supply for around 5 minutes in order to reset
after the second stage is triggered.
