PLUMBING & BATH FEATURES
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.
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 water line and 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:

All 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 manufactures brochure.
CITY WATER CONNECTIONS
When connecting your unit to city water, 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.
When connecting your unit to city water, use the water hose and connect to #1 in the above figure. While doing
so, make sure the blue handle is turned to CITY.
