Fresh Water Tank
Water is drawn from the fresh water tank
(1) located beside the waste water tank (2)
in the left hand side luggage compartment.
Refill fresh water tank with potable drink-
ing water only. Tank volume is 9 gallons
(34 liters). On top of the tank is a hose (3)
that serves as a filler and a vent tube. In the
bottom of the tank is a drain valve (4), with
a hose attached, for draining the tank to the
outside.
It is not recommended to let water remain
unused in the tank for over 2 months.
Clean and refill as necessary.
CAUTION
USE POTABLE DRINKING WATER
ONLY. Verify with the supplier of any
water prior to filling the fresh water tank
that it is potable to avoid contamination
of the tank. In the event that non-potable
or contaminated water enters the fresh
water tank, it should be drained and the
tank should be cleaned out with a good
commercial cleaner/disinfectant. The
tank should also be tested for purity
prior to being used for drinking. It may
be necessary to replace the tank if it
cannot be cleaned properly.
CAUTION
Fresh water and waste water tanks must
be drained if the vehicle is not being
used and the outside temperature is be-
low freezing. Also drain the hose from
the pump to the faucet. Failure to drain
the system may result in component
damage due to water forming ice.
