Do not allow the pump to run when the fresh water supply tank is empty.
Continued operation with a dry tank may open an electrical circuit and/or
damage the water pump.
To start pump after unhooking city water supply or first time use
proceed as follows:
• Fill the fresh water tank.
• Open all valves and faucets except the drain valves. This includes hot
and cold water valves, all faucets and the shower.
• 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 simply tightening the hardware. Check the
following items along with other particulars of the system.
The water pump will not start/blows the circuit:
• Check the electrical connections, fuse, breaker, main switch and ground
connection.
• Is the motor hot? The thermal breaker may have triggered. It will reset
when cool.
• Is the voltage present at the switch? Bypass the pressure switch.
• Does the pump operate?
• Check the charging system for correct voltage and check the pump for
the proper ground connection.
• Look 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.
