SPECIFICATIONS
Motor: Permanent Magnet, Ball Bearing Totally Enclosed. CE Models are fully suppressed.
Pump: Three chamber diaphragm design Self-priming up to 9 feet suction lift; Pump able to run dry without damage

OPERATION
With pump switch off and battery fully charged, fill water tank, open all faucets, then turn pump switch on. Water will begin to flow. When the water is free of air, turn faucets off. Remember, you are filling the water heater and the toilet and shower lines. When all valves are shut-off, pump will stop. Should pump fail to stop, turn switch off and see the trouble shooting guide. CAUTION - Pump surface will get hot to the touch if operated for extended periods of time under pressurized conditions.

INSTALLATION
STEP 1
Remove shipping plugs from pump ports. Some water from factory testing may spill out.
STEP 2
Connect fittings supplied with the pump to the RV’s plumbing. Use 1/2’ I.D. Flexible hose (preferably braided or reinforced) to reduce vibration through the plumbing system as shown on Fig. 1. Use hose clamps on the slip-on barb hose connectors.
STEP 3
Slide rubber mounts fully into 4 mounting tracks.
STEP 4
Mount pump vertically, with pump head down or horizontally in an accessible location. If mounting vertically, motor up, attach motor mounts first then pump head mounts, while supporting weight of pump.
STEP 5
Install inlet A and discharge B port connectors. Firmly push slide clips C forward to lock port connectors in place.
STEP 6
Install a Flojet strainer in an accessible location (for inspection and cleaning) between the tank and pump inlet. This strainer or equivalent is required for pump warranty to be valid.

WIRING
STEP 1
Use 14 gauge stranded wire to 20’, 12 gauge to 50’, from power source.
STEP 2
Use a 10-15 amp rated on-off switch on the (+) positive (red) motor lead.
STEP 3
Install a 10 amp fuse protection on the positive lead.

Note: To help reduce noise and vibration of the pump through the system use flexible lines on the inlet and outlet of the pump as shown above. Be sure to use lines rated to not collapse under pump vacuum.


TROUBLESHOOTING

WARNING: BEFORE SERVICING PUMP, TURN OFF PUMP AND DRAIN WATER FROM SYSTEM!! AUTOMATIC WATER SYSTEM PUMP SERVICE PARTS

Failure to Prime - Motor operates, but no pump discharge
• Restricted intake or discharge line
• Air leak in intake line
• Debris in pump
• Punctured pump diaphragm (pump leaks)
• Crack in pump housing

Motor falls to turn on
• Loose wiring connection
• Pump circuit has no power
• Blown fuse
• Pressure switch failure
• Defective motor

Pulsating Flow
• Restricted pump delivery. Check discharge lines, fittings
and valves for clogging or under-sizing

Pump Fails to Turn Off After All Fixtures Are Closed
• Empty water tank
• Insufficient voltage to pump (low battery)
• Punctured pump diaphragm (pump leaks)
• Discharge line leak
• Defective pressure switch

Low Flow and Pressure
• Air leak at pump intake
• Accumulation of debris inside pump and plumbing
• Worn pump bearing (excessive noise)
• Punctured pump diaphragm (pump leaks)
• Defective motor

SYSTEM CARE AND MAINTENANCE
Allowing water to freeze in the system may result in damage to the pump and plumbing system.
Non-Toxic antifreeze for potable water may be used with Flojet pumps.
Follow Vehicle manufacturers recommendations instructions for their specific winterizing and drainage procedures.

WARNING: DO NOT use automotive antifreeze to winterize potable water systems. These solutions are highly toxic and may cause serious injury or death if ingested.

1. Drain the water tank. Open tank drain valve and plumbing drain valves if applicable. You may use the pump to drain the tank by opening all the faucets in the system. Allow the pump to operate until the tank is empty. Do not operate the pump more than 15 minutes continuously.
2. Open all faucets and flush the toilet to purge all the water from the pump and the plumbing system. Run the pump until no water is coming through the faucets.Turn power to the pump off. Be sure that all the water from the drain lines are drained.
3. Remove quick connect inlet and outlet fittings from the pump and turn the pump on to pump out remaining water from the pump head. Be sure to have a catch pan or a rag under the pump to prevent water from spilling on to the RV. Turn the pump off once the plumbing is empty. Leave the fittings disconnected from the pump until the system is ready to be used again. Make a note on your tank filler that the plumbing is not connected.
4. Be sure that all faucets are left open to protect against damage to the plumbing

SANITIZING
Portable water systems require periodic maintenance to deliver a consistent flow of fresh water. Depending on use and the environment the system is subject to, sanitizing is recommended prior to storing and before using the water system after a period of storage. Systems with new components, or ones that have been subjected to contamination, should also be disinfected as follows:

NOTE: The sanitizing procedure is in conformance with the approved procedures of RVIA ANSI A119.2 and the US Public Health Service.
1. Use of the following methods to determine the amount of common household bleach needed to sanitize the tank.
1. A) Multiply “gallons of tank capacity” by 0.13; the result is the ounces of bleach needed to sanitize the tank.
1. B) Multiply “Liters of tank capacity” by 1.0; the result is the milliliters of bleach needed to sanitize the tank.
2. Mix into solution the proper amount of bleach within a container of water
3. Pour the solution (water/bleach) into the tank and fill the tank with potable water.
4. Open ALL faucets (hot and cold) allowing the water to run until the distinct odor of chlorine is detected.
5. The standard solution must have four (4) hours of contact time to disinfect completely. Doubling the solution concentration allows for contact time of one (1) hour.
6. When the contact time is completed, drain the tank. Refill with potable water and purge the plumbing of all sanitizing solution.
