Follow the instructions supplied by the vehicle manufacturer to check
the cooling water level. The water in the heating system must contain at
least 30 %, maximum 60% of a branded anti-freeze.
If you use pure water, if it overheats you may lose some of the cooling
water as a result of its low boiling point, and this will then have to be top-
ped up.
Additives in the heating system must not be aggressive to metal, plastic
or rubber and must not form any deposits.
The opening pressure in the vehicle's cooling system (generally speci-
fied on the coolant sealing cover) must be between 0.4 and 2.0 bar.
A temperature of 100 °C (storage temperature) must not be exceeded
in the vicinity of the control device (for example when completing pain-
ting work on the vehicle).
If this temperature is exceeded, the electronic systems may suffer per-
manent damage.
The heaters must only be operated with natural gas (CNG).
Due to the hardly audible combustion noise of the heater, particular care
is required when working near the device. In such cases the heater shall
be always protected against an inadvertent on-switching.
