To turn the water pump on or off:
• Momentarily press the water pump switch. The indicator lamp will
illuminate when the water pump is turned on.
CAUTION: Do not continue water pump operation if the
fresh water holding tank is empty. Damage to the water
pump or electrical supply system may result.
Use the following procedure to operate the water pump after
unhooking from the city water supply or after storage:
• Close all drain valves and low point drains.
• Fill the fresh water tank.
• Open the hot and cold water valves of each faucet.
• Turn the water pump on. Wait for the water lines and the hot water tank
to fill.
• Close each faucet when it delivers a steady stream of water
(cold water faucets first).
Vibration induced by road conditions can cause the plumbing or pump
hardware to loosen. Check for system components that are loose. Many
symptoms can be resolved by tightening the hardware. Check the following
items:
The water pump will not start or blows the fuse:
• Check the electrical connections, fuse or breaker, main switch
and ground connection.
• Check the electrical connections at the latching controller.
• Is voltage present at the pressure switch? Bypass the
pressure switch.
• Is the latching controller grounding the water pump?
• Check the charging system for correct voltage and good ground.
• Check for an open or grounded circuit or motor.
• Check for seized or locked diaphragm assembly (water frozen).
The water pump will not prime/sputters:
(No discharge/motor runs):
• Is the strainer clogged with debris?
• Is there water in the tank or has air collected in the hot
water heater?
• Is the inlet tubing/plumbing sucking in air at plumbing
connections (vacuum leak)?
• Check for proper voltage with the pump operating.
• Look for debris in the pump inlet/outlet valves or
dry/swollen valves.
• Check the pump housing for cracks or loose drive
assembly screws.
