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.

INSTALLATION
STEP 1
Determine the distance from the power source to the pump
and then double the measurement. Wire gauge installation is
determined on the entire run length, to the pump and back.
STEP 2
Connect to power supply lead (red)(+) to the positive (+)
terminal on the battery or through a properly installed fuse /
circuit breaker panel. Then run the length of wire to the pump,
connecting the red wire through a switch appropriately rated
to the pump’s current requirements.
STEP 3
Route the wire so as not to create hazards in operation of the
engine, movement of steering components or human traffic.
WIRING (Fig. 3)
-
STEP I
Remove shipping plugs from pump ports. There may be slight
amount of water that drains out of the pump as all pumps are
tested at the factory before shipment.
STEP 2
A direction arrow can be found on the pump head to indicate
direction of flow. Connect the appropriate sized hose to one of
the supplied fittings and then connect the hose to the water
supply tank outlet. To reduce vibration use 1/2” (13 mm)
braided or reinforced flexible hose on the inlet and outlet of the
pump as shown on Fig.1. Use hose clamps on the slip-on barb
connectors.

STEP 4
Connect the red lead to the red lead on the pump housing located
pressure switch.
STEP 5
Connect the black lead from the pump to the ground or negative
power side (-) of the vessel.
STEP 6
Turn the system off when not in use for extended periods of time or
when the water supply tank is empty.
STEP 7
After installation, check 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 for proper pump operation and pump
motor life.
Motor case could get hot during
extended operation. Prolonged contact with skin may
cause a burn.
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.
STEP 3
Slide rubber mounts fully into 4 mounting tracks.
STEP 4
Mount pump horizontally in an accessible location or vertically with
pumphead down. Support weight of the pump and attach
pumphead mounts first then motor mounts second.
STEP 5 (Fig. 2)
Install inlet A and discharge B port connectors. Firmly push slide
clips C forward to lock port connectors in place.
STEP 6 (Fig. 4)
Install a PumpgardTM strainer in an accessible location (for
inspection and cleaning) between the tank and pump inlet in order to
protect valves from debris.
IF YOU ARE NOT FAMILIAR WITH APPLICABLE ELECTRICAL STANDARDS, HAVE THE UNIT INSTALLED BY A QUALIFIED
ELECTRICIAN.
Suggested wiring information is given as a reference. For proper information, please reference USCG regulations for marine applications
and wiring gauges, connectors and fuse protection.

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 Jabsco pumps. Follow manufacturer’s
recommendations. Refer to boat or equipment manufacturer’s
instructions for their specific winterizing and drainage
procedures. Do not use automotive antifreeze to winterize
potable water systems . These solutions are highly toxic and
may cause serious injury or death if ingested.
Winterizing
2. Open all faucets and purge the water from the plumbing
system. Turn off power to the pump. Be sure that all the water
from the drain lines is 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 onto the boat. 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.
1. Drain the water tank. Open tank drain valve. 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.

PROBLEM SOLUTION
Pulsation Flow - Pump cycles on and off Restricted pump delivery. Check dischrage lines, fittings and valves for
undersizing or clogging. Clean screens in faucets. Some filters or purifiers
are highly restrictive. Filters/purifiers with high pressure drop may require
a separate line and/or the installation of an accumulator tank in the
system.
Failure to Prime - Motor operates, but no pump discharge Restricted intake or dscharge line
Air leak in intake line
Punctured pump diaphragm
Debris under flapper valves
Crack in pump housing
Pump fails to turn off after all fixtures are closed Empty water tank
Punctured pump diaphragm
Discharge line leak
Defective pressure switch
Insufficient voltage to pump
Debris under flapper valves
Low flow and pressure Air leak at pump intake
Accumulation of debris inside pump and plumbing
Worn pump bearing (excessive noise)
Punctured pump diaphragm
Defective motor
Motor fails to turn on Loose wiring connection
Pump circuit has no power

Sanitizing
WARNING: BEFORE SERVICING PUMP, TURN OFF PUMP AND DRAIN WATER FROM SYSTEM!!
TROUBLESHOOTING
www.jabsco.com
Potable water systems require periodic maintenance to deliver a consistent flow of fresh water. Depending on use and the
environment the system is subjected 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 the US Public Health Service.)
1. Use the following methods to determine the amount of common household bleach needed to sanitize the tank:
A. Multiply “gallons of tank capacity” by 0.13; the result is the ounces of bleach needed to sanitize the tank
(30 gallons X .13 = 3.9 oz bleach).
B. Use the number of liters of tank capacity to determine the number of mililiters of bleach needed to sanitize the tank
(120 liters of tank capacity = 120 mililiters of bleach).
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 door of chlorine is detected.
5. The standard solution must have four (4) hours of contact time to disinfect completly. 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.
