4-10 Fresh Water System
450 LXi Owner Manual
~ 4-10-2 ~ Rev. “C”
Drain tanks – Open the Cold Water Drain valve (as in Step 1), and allow the tank to drain completely.
Refi ll tanks – Close the Cold Water Drain valve and turn on the water supply to the municipal water inlet. Turn on the
Tank Fill switch and fi ll the tank completely. When the tank is full, turn off the Tank Fill switch, shut off the water supply
and disconnect the hose. Then replace the fi ll cap and turn on the water pump. When water fl ows from the opened
faucets, close them and open the other faucets until water fl ows. This fl ushes the system, removing trapped air from
piping and ensures that the fresh water supply is ready for use.

Repeat steps 6 and 7
until the chlorine smell and taste is no longer present at the faucets.
4-10.3.2 Water Filter Replacement
Depending upon the condition of the municipal water used, the fi lter media will degrade with use. The only practical way to
determine when replacement is required is to go by the sense of taste. It is recommended that the fi lter be changed after
prolonged storage.
4-10.3.3 Water Heater
With the Webasto system at operating temperature, the domestic water is automatically heated as it is being used. Open any
hot water faucet and a continuous supply of domestic hot water will be present within a few seconds. This is accomplished by
the Webasto’s domestic hot water zones, which are an integral part of the heating system. A mixer valve has been installed to
ensure that excessively hot water does not fl ow to the faucets.

4-10.3.4 Water Pump
The water pump is located in the road side luggage compartment (bay 3). The pump employs state-of-the-art electronics to
automatically control motor speed. The pump adjusts its speed as you open and close water fi xtures. If the pump has been
out of service for a period of time, it is advisable to open a faucet before turning them on. When water fl ows steadily from the
opened faucet, close the faucet and observe that the pump shuts off when the system becomes pressurized. (It may also
be necessary to bleed the air from the other faucets as well.) When the fresh water supply tank level is low or empty, shut
the pump off to prevent possible damage to the pump motor. In addition to integral motor overload protection; the pump
mechanism is also protected from damage by the presence of a fi lter at the water pump inlet. The fi lter should be cleaned
periodically.
Under normal usage, the water pump should require no periodic maintenance other than ensuring that the input water supply
is properly fi ltered of particles that could damage the pump mechanism. Pump failures can generally be tied to the plumbing
system or to electrical wiring. If a pump fails to operate properly, refer to the general troubleshooting guide.
4-10.3.5 Water Pump Switch
The central control switch, labeled water pump, for the water pump is in the bathroom.
The associated indicator is lit whenever power is being supplied to the pump. Turning ON the switch pressurizes the water
system, with the pump maintaining constant pressure. Continuous or erratic pump operation can indicate an empty water
tank, system leakage or air lock in the water lines. Switches enabling the water pump are located in the bathroom, in the
kitchen and in the roadside holding tank bay. These switches are labeled water pump.
CAUTION!!
Do not permit sanitizing or antifreeze solutions to enter water fi lter.
CAUTION!!
The mixer valve is not an anti-scald device. Always exercise reasonable caution when
using hot water.
CAUTION!!
Do not turn the Webasto’s unit off if the outside temperature is 32°F or lower when the
potable water system is not drained.
Note that detailed pump repairs and overhaul should be performed by a qualifi ed repair facility.
