3 Assemblies and components
3.3
Heat exchanger
In the heat exchanger (1,
) the water flowing
through is heated by heating cartridges (6) arranged in it.
The cylindrically welded construction has a water inlet (2)
and a water outlet (3). The heater is integrated into the
cooling water circuit via these two connection ports.
In the water outlet (3) the control thermostat (4) is screwed
in. In the wall of the heat exchanger the temperature
limiter (5) is installed.
The plate at the front has receiving openings with threads
for the heating cartridges (6).
3.4
Heating cartridges
At the end of the rod-shaped, water-proof heating cart-
ridges (6,
) there is an external thread with a
hexagon for screwing in and the electrical cables are led
out.
ATTENTION:
The heating cartridges must always be screwed in
with a new gasket!
3.5
Control thermostat
The control thermostat (4,
) captures the coolant
temperature at the heat exchanger outlet.
