APPLICATIONS

The PAR-MAX Automatic Water System Pump is

designed for self-contained boats and RV’s with multiple

fixture water systems. The system operates auto-

matically. When a fixture is opened, the pump instantly

begins operation to provide a smooth constant flow from

tank to faucet. Closing the faucet automatically discon-

tinues pump operation.

The Deluxe model 31630-Series has a corrosion

resistant coated motor for extra protection in harsh

environment applications.

INSTALLATION

MOUNTING

The PAR-MAX pumps are self-priming and may be locat-

ed above or below the fresh water tank in a dry location.

To vertically mount these units, it is best to do so with the

motor on top. This will prevent water dripping on motor

in the event of a leak. Place pump on a solid surface

and secure with four mounting screws (not included)

being careful not to compress the rubber grommets

which act as shock absorbers.

PLUMBING

Select two of the port adaptors supplied to match your

plumbing system. Flexible potable water hose or PEX

tubing is recommended instead of rigid piping at

pump. If you choose to use rigid piping, provide a short

length of hose between pipe and the pump to avoid

noise and vibration. Use clamps at both ends of hose to

prevent air leaks into the water line. NOTE: Intake hose

must be minimum 1/2" (13 mm) ID reinforced hose. Main

distribution line from pump outlet should also be 1/2" (13

mm) ID with branch and individual supply lines to outlets

no smaller than 3/8" (10 mm). A Jabsco “Pumpgard” in

line strainer should be installed between pump and tank

to keep debris out of pump and system. Fresh water tank

must be vented. Avoid any kinks or fittings which could

cause excessive restrictions. Remember to periodically

clean faucet and “Pumpgard” screens.

WIRING

In an easily accessible location, install a switch (Jabsco

44960-Series) to control electricity to the pump. Turn the

pump off when not used for extended periods or when

the tank is empty.

The electrical circuit should be protected with an over-

current protection device in the positive lead. See chart

for proper size. The pump circuit should not include any

other electrical loads. The free lead at the pressure

switch is positive. Black wire from the motor is negative.

Select wire size from chart below. Use total length of wire

from the battery to pump and return. Chart allows for 3%

voltage drop. If in doubt, use next larger wire size.

If you are not familiar with applicable electrical stan-

dards, have the unit installed by a qualified electrician.

After installation, check the voltage at the pump motor.

Voltage should be checked when pump is operating. Full

voltage must be available at the pump motor at all times.

OPERATION

1. Check level of water in tank.

2. Open all faucets hot and cold.

3. Switch on power to pump and wait for hot water tank

and water lines to fill.

4. Close each faucet as flow becomes steady and free of

air (close cold water faucet first). Pump should shut off

soon after closing last faucet.

5. Pump is now ready for automatic operations. It will

start when faucet is opened and stop when faucet is

closed.

6. If pump will be inoperative for a considerable length of

time, turn off circuit to pump and bleed system by

opening faucet.

Explosion hazard. Do not pump

gasoline, solvents, thinners or other

flammable liquids. To do so can

cause an explosion resulting in injury

or death.

WARNING

!Fire hazard. Wiring must comply with

applicable electrical standards and

include a properly sized fuse or circuit

breaker. Improper wiring can cause a

fire resulting in injury or death.

ACCESSORIES

SNAP-IN PORT SYSTEM

WINTERIZING YOUR WATER SYSTEM

To winterize, it is not necessary to drain the water from

the entire water system. Blowing into the lines to remove

the water from your water system is not satisfactory due

to the check valve mechanism built into the pump.

Follow these steps to remove all water from your water

system:

1. Drain water by opening tank drain, or open a fixture to

allow pump to operate until tank is dry.

2. Open the lowest outlet in water system to drain lines.

3. To remove any remaining water (about a cup), remove

outlet hose on pump and activate pump. To blow out

lines, attach air nozzle where outlet hose was

removed. Make sure all fixtures are open before starting.

4. Your water system is now winterized. Don’t forget to

reattach the outlet hose to pump and close all fixtures.

PAR-MAX pumps have thermal overload protected motors. The motor will automatically shut off as

temperature rises due to an overload condition. If the motor shuts off in this manner, close all nozzles, faucets or

valves. After a cooling off period, the pump will automatically re-start.

DO NOT USE AUTOMOTIVE TYPE ANTI-FREEZE. IT IS POISONOUS. USE OF THIS TYPE ANTI-

FREEZE WILL CAUSE SERIOUS INTERNAL INJURY OR DEATH.
