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.

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.
