OPERATING INSTRUCTIONS
1. MOUNTING – Jabsco diaphragm pumps are self-priming and
should be located in a dry location above or below the fluid supply.
To vertically mount these units, it is best to do so with the motor on
top. This will prevent fluid dripping on the motor in the event of a
leak. PLACE PUMP ON A SOLID SURFACE AND SECURE WITH FOUR
MOUNTING SCREWS BEING CAREFUL NOT TO FULLY COMPRESS
THE RUBBER GROMMETS WHICH ACT AS SHOCK ABSORBERS.
2. PLUMBING – Port adaptors are supplied to fit 1/2" (13 mm) dia.
ID hose or 1/2-14 female straight pipe threads. Use Teflon* (PTFE)
type tape when threading straight pipe threads to tapered pipe
threads. Select two of the port adaptors supplied to match your
plumbing system. FLEXIBLE HOSE OR TUBING IS RECOMMENDED
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. NOTE: Intake hose should be at least 1/2" (13mm)
ID reinforced hose. A 40 mesh strainer should be installed at the
pump inlet to keep debris out of the pump. Avoid any kinks or fit-
tings which could cause excessive restrictions. Remember to peri-
odically clean "Pumpgard" screens.
WARNING
Explosion hazard. Do not pump gasoline,
solvents, thinners or other flammable
liquids. To do so can cause an explosion
resulting in injury or death.
3. WIRING DC MODELS – In an easily accessible location, install
an "on-off" switch (Jabsco 44960-Series) to control electricity to the
pump. Turn the pump off when not used for extended periods, or
when fluid supply is depleted.
The electrical circuit should be protected with an overcurrent pro-
tection device in the positive lead. See chart for proper size. The
pump circuit should not include any other electrical loads. The
open terminal on the pressure switch is positive. Black Wire from
the motor is negative, orange is positive.
Select wire size from chart. Use total length of wire from electrical
source to pump and return. Chart allows for 3% voltage drop. If in
doubt, use next larger wire size.

NOTE: If operating pressure exceeds 40 psi (2.8 bar), a pressure
relief valve should be installed in the system.
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.

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.
4. SELF-PRIMING – Pump is self-priming. Vertical dry lift capacity is
10 feet (3m) (wet) 5 ft (1.5m) (dry) min. Be sure suction piping is
airtight or pump will not self-prime.
5. RUNNING DRY – Pump can run dry indefinitely without damage.
6. CHEMICAL COMPATIBILITY – Fluids being pumped must be
compatible with the materials of construction. Consult factory for
Chemical Compatibility Guide. Pump should be flushed with clean
water or neutralizing solution after each use to prolong pump life.
7. PRESSURE – Maximum continuous duty discharge pressure is
15 psi.
8. TEMPERATURE – The maximum recommended fluid tempera-
ture is 130°F (54°C.) Minimum recommended fluid temperature
is 45°F (7°C).
