Water Pump
The water pump is self-priming and totally automatic, operating on demand whenever water is required.
The water pump is used to pressurize the freshwater system when the unit is not connected to city water.
The switches (Figure 11-5) to this pump may be located in the bathroom, or sanitation-service compartment
(Figure 11-6). To start the pump, follow these instructions:
1.
Fill or partially fill the fresh water supply tank.
2.
Open the kitchen and bathroom faucets.
3.
Turn the water pump switch "on" and allow the water to fill the water line and
the hot water heater.
4.
Close each faucet after it delivers a steady stream of water (close the cold-water faucet first).
Leave the hot-water faucets "on" until they also deliver a steady stream of water.
This procedure will assure that the water heater is filled with water.
5.
The water pump should stop running once all faucets are closed.
6.
The water pump is now ready for automatic operation. The pump will run when a
faucet is open and stop when a faucet is closed.
7.
Never allow the pump to run for long periods of time without water being present
in the supply tank, as doing so may cause physical damage or blow fuses.
If water does not flow when a faucet is turned "on" while using the demand
system, use the following troubleshooting chart:

SITUATION

Pump not running
All of the water should be drained from the freshwater system when the unit is not in use for extended periods.
For more detailed information regarding the water pump, one should refer to the water pump manufacturer's
brochure in your Allegro Owner's Information Package.
City Water Connection
When connecting your unit to city water, be certain to use the water hose manufactured and labeled for potable water
service--this will assure that the hose selected for use will not alter the taste of the water. To connect the city water
supply to the vehicle, connect one end of the hose to the city water supply; this connection will usually be to a faucet or
valve similar to your garden hose valve at home.
