10.3.3 Waste water tank heater (special equipment)
The waste water tank may be heated and is insulated. The integrated frost
guard prevents waste water from freezing.
A switch (Fig. 207,1 or Fig. 208) on the front of the bench seat or bed may be
used to switch the frost guard on and off.
The frost guard begins to heat the waste water as soon as the water temper-
ature drops to approx. 5 °C. The frost guard ends the heating process when
the waste water reaches a temperature of approx. 10 °C.
10.4 Filling the water system
