Water Pump Operation
Your King Aire has a fully self-contained fresh water system with a fresh water storage tank, and
a “demand” style 12 volt DC electric water pump. This pump is designed to build pressure in the
fresh water plumbing in your coach, operating only when there is a demand for water on the
system. When any water pump switch is turned on, the water pump will come and build pressure
in the system, and will shut off as soon as the system is correctly pressurized. When a faucet is
opened, the pump will turn on and operate as necessary to maintain the preset pressure in the
system.
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 fresh water system when the unit is not
connected to city water. The switches to this pump may be located in the bathroom, on the
monitor panel, and in the water works compartment. 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 first). Leave
the hot water faucets on until they also deliver a steady stream of water. This will ensure that
the water heater is filled with water.
5.
The water pump should stop running once all faucets are closed.
6.
The pump is now ready for automatic operation. The pump will run when a faucet is opened
and stop when a faucet is closed.
7.
Never allow the pump to run for long periods of time without water in the supply tank. Pump
damage or blown fuses may result.
All of the water should be drained from the fresh water system when the unit
is not in use for more than one week. For more detailed information regarding the water pump,
refer to the water pump manufacturer’ s brochure in your Owner’ s Information Package.
