14.1 Introduction
All the LAIKA-models are equipped with a water system
expressly conceived to grant a high comfort and a
suitable safety level.
Here below you will find some useful advice that will
allow you to avoid damages to the system, especially in
case of very low temperatures:
• do not use in any case abrasive or acid products to
clean the pipes;
• to keep the water pump functioning properly, period-
ically clean the filter;
• in case of frost, the system must be completely
emptied (please also read “Maintenance – Inactivity
of the vehicle”). It is very important to be sure that no
water still remains in the final part of the system, in
the taps of the sink and in the lavatory.
14.2 Water Pump
The pump takes water from the selected tank (standard
or additional, if installed). The water goes through a
filter located in the pump inlet and is then sent into the
system, flowing inside antifreeze polybuthylene pipes to
reach the taps. The pump is fitted with a pressure
switch and it works each time a water tap is turned on.
Refer to the producer’s handbook for further infor-
mation on the pump.
Vehicles equipped with additional fresh water
tank (optional)
Vehicles equipped with additional fresh water tank are
provided with a tap, usually installed next to the pump,
to select the tank (standard or extra).
