WARNING!
Explosion hazard. DO NOT PUMP
GASOLINE, SOLVENTS, THINNERS OR
OTHER FLAMMABLE LIQUIDS WITH A FLASH POINT BELOW
100°F (37.8°C). Doing so may result in an explosion which
could cause personal injury, death or property damage.
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
personal injury, death or property damage.
MOUNTING
Jabsco pumps are self-priming and may be located above or be-
low 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 wa-
ter 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 grom mets 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 recommend-
ed instead of rigid piping at pump. If you choose to use rigid pip-
ing, 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
TM
” 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
TM
” screens.
WIRING
In an easily accessible location, install a switch to control electricity
to the pump. Turn the pump off when not used for extended peri-
ods or when the tank is empty.
The electrical circuit should be protected with an over current pro-
tection 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 standards,
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.
CAUTION: Motor case will get hot.
Prolonged con tact during operation may
cause a burn.
WARNING: DISCONNECT POWER TO
