2.6 Electrical system
 Only allow qualified personnel to work on the electrical system.
 Prior to carrying out work on the electrical system, switch off all de-
vices and lights, disconnect the battery and disconnect the vehicle
from the mains.
 Only use original fuses with the stipulated values.
 Only replace defective fuses when the cause of the defect is known
and has been remedied.
 Never bridge or repair fuses.
2.7 Water system

Water left standing in the water tank or in the water pipes becomes
undrinkable after a short period. Therefore, before each use of the ve-
hicle, thoroughly clean the water pipes and the water tank. After each
use of the vehicle completely empty the water tank and the water
pipes.

In the case of lay-ups lasting more than a week disinfect the water
system before using the vehicle (see chapter 11).

If the vehicle is not used for several days or if it is not heated when there
is a risk of frost, empty the entire water system. Make sure that the 12 V
power supply on the panel is switched off. Otherwise, the water pump
will overheat and may get damaged. Leave the water taps on in central
position. Leave all drain cocks open. Frost damage to appliances, frost
damage to the vehicle and deposits in water-carrying components can
be avoided in this way.
