·Mount the pump within 5 feet of the tank for best performance and pump life. The farther it

pulls the more work it dose, increasing vibration and noise, and reducing the output and pump

life. The lift may decrease as the pump is used.

· Mount pump in a space of at least 1 cubic foot for adequate ventilation to prevent

overheating.

·Pump may be mounted in any position.

·Mount pump for easy access for cleaning strainer, maintenance and service.

·Mount pump on a solid surface to prevent vibration and noise.

Typical Pump Installation

Installation & Maintenance Manual

Installation Preparation

The goal of installation is to provide a quite, easy-to-maintain installation with good flow and

low backpressure. This can be accomplished with the following guidelines:

Follow all marine/RV/agriculture safety guidelines if installing in a watercraft, including

waterproof connections.

· Mount on a solid surface in an accessible location for strainer cleaning and pump

maintenance.

·Use flexible high-pressure hose on the pump inlet and outlet. The pumps ports and strainer

should not be connected to plastic or rigid pipe, or the pump’s normal motion will transmit

through rigid plumbing causing noise, and possibly loosening or cracking components.

·Pump must use an adequate 40-mesh strainer.

·Use a minimum of 3/8” [9mm] Inner Diameter plumbing. Smaller ID plumbing can cause high

backpressure, cycling, low flow and noise.

·Pump is designed for intermittent duty only.

·Do not use these pumps for running a Reverse-Osmosis [RO] Filtration System. High pressure-

continuous duty usage will shorten the life of the pump and it not covered under warranty.

·Wire Size is 20 GA MINIMUM

·Minimum power requirement is a 10 Amp circuit.

· Reduce restrictions on inlet and outlet. This includes small inner diameter shut-off valves,

winterizing valves and elbows.

Installation of a strainer is required to prevent debris from entering the pump.

For noise and vibration reduction we recommend at least 5 inch [130mm] of flexible high-

pressure hose to both ports. The pump ports and strainer should not be connected to plastic or

rigid pipe. This hose should be anchored where it meets the hard plumbing to reduce plumbing

vibration.

Normal pump maintenance is all that is needed: Checking and cleaning of the strainer, normal

sanitizing and winterizing and occasionally checking all plumbing hardware and fittings for

tightness. Lack of sanitizing is the number one reason for premature pump failure and poor

performance over time. Lack of sanitizing will cause scale build-up on the diaphragm and valves.

· The pump works best on an individual filtered circuit, protected by the fuse or breaker

specified on the label.

·A switch is recommended and should be on the positive lead.

·Wire Size: Proper wire size is required for good pump operation. If the wire is too small, low

voltage will affect the pump performance and can create a fire hazard.

·SHUT OFF POWER TO THE PUMP WHEN RV OR BOAT OR YOUR EQUIPMENT IS UNATTENDED.

The pump operates normally up to factory set shut-off pressure. As a faucet is opened back up,

the pressure will drop, the switch will close and full flow is again obtained. Pump cycling [On-

Off-On] may occur if the faucet is not open enough to allow flow.

Lower voltage=lower flow, higher voltage=higher flow.

Remember your electrical safety: it is always best to shut power to the pump OFF when leaving

the RV or boat or your equipment unattended.

MAINTENANCE

Refer to the RV or watercraft or other equipment owner’ s manual for specific

winterizing instructions.

If water is allowed to freeze in the system, serious damage to the plumbing and the pump may

occur. Failure of this type will void the warranty. The best guarantee against damage is to

completely drain the pump. When used per manufactures recommendations non-toxic

antifreeze for potable is safe for use with this pump.

To drain the pump perform the following:

1. Drain the water tank. If the tank doesn’t have a drain valve, open all faucets allowing the

pump to operate until the tank is empty.

2. Open all the faucets (including the lowest valve or drain the plumbing), allow the pump to

purge the water from the plumbing, and then turn the pump OFF.

SANITIZING

Potable water systems require periodic maintenance to keep components working properly

and deliver a consistent flow of fresh water.

Sanitizing is recommended: prior to storing, after a period of storage, or any time the system is

opened or contaminated.

NOTE: Check your RV or Watercraft or other equipment Owner’s Manual for specific

instructions.

3. Using a pan to catch the remaining water, remove the plumbing at the pump’s inlet/outlet ports. Turn the pump ON, allowing it to operate until the water is expelled. Turn OFF power to the pump once the plumbing is emptied. Do not reconnect the pump plumbing. Make a note at tank filter as a reminder: “plumbing is disconnected’. 4. All faucets must be left open to guard against any damage. 5. Potable anti-freeze maybe poured down drains and toilets to protect p-traps and toilet seals.
