Pump Setup
Jabsco Utility Puppies can be mounted on any flat surface. Fit the
pump in a dry, well ventilated position where there is full access
for service. If installed in the vertical position, the motor must
be above the pump head. Use the rubber grommets provided to
minimize vibration. M6x25 screws, M6 nuts and M6 washers to
BS4320 form A are suggested. Do not over tighten the mounting
screws.
Dependent on model, ¾" BSP or NPT threaded hose connectors
should be used to connect 1" (25.4mm) inlet and outlet hoses.
Secure the hose to the fitting with stainless steel hose clamps.
Use spiral reinforced hose (with a smooth internal bore) that will
not collapse under suction, or ridged or semi ridged pipework.
The pipework must be compatible with the liquid being pumped.
Pipe runs should be kept as straight and short as possible. For BSP
models, Jabsco ¾" BSP thread fitting part number 23543-1200
with bonded washer SP1613-1415 can be used.
When considering longer pipe runs, ensure the overall pump
differential pressure is not exceeded due to pipe losses and static
heads. Ensure priming heights are within the pump capability
and included in pipe loss calculations. Keep the inlet pipe run
short, placing the pump as close to the feed fluid as is practicably
possible
Electrical Setup
ATTENTION
•
All electrical installation must be installed according to
national wiring rules. Ensure only the correct rated fuses are
fitted. Please refer to the Pump specification Table in section
5 for a suitable size fuse that must be fitted to ensure the
safety of product. Check the voltage on the pump data label
•
Wire the pump to a DC source of correct voltage and
adequate amperage capacity
•
Make all electrical connections in dry locations. Connections
in humid environments should be sealed to prevent
corrosion.
•
Protect the circuit with a correctly sized fuse or circuit breaker
in the positive (+) lead as close as possible to the power
source. Select the correct cable size from the chart above.
Inadequate voltage at the terminals when the pump is
running (less than 10% below rated voltage at full load) due
to partially discharged batteries or insufficient cable size
may result in blowing fuses, failure to start or poor pump
performance.
•
The pump may be switched manually, via a relay or automat-
ically via a float switch. Only use switching gear of adequate
power rating and position after the fuse.
•
Connections made should use insulated spade and blade
connectors or equivalent robust connection capable of
handling the fuse rated current.

ATTENTION
Connecting wire lengths may be extended beyond the standard
recommendations above. The following considerations should
be made by qualified personnel when selecting suitable wire
diameter
•
Voltage drops occur over long wire runs. Ensure these
voltage drops do not exceed the recommended 10% from
rated voltage drop.
•
As a guideline, the voltage drop E, at load, in volts may be
calculated by the following formula:
Where S is the cross-sectional area of the conductor in square
millimetres; I is the load, in amperes; L is the length, in metres, of
the conductor from the positive power source to the pump motor
and back to the negative source connection.
6. PRODUCT OPERATION
Permitted Fluids
ATTENTION
DO NOT USE WITH LIQUIDS WITH A FLASH POINT
BELOW 100°F (37°C) OR USE WHERE FLAMMABLE
VAPORS ARE PRESENT.
•
Ensure operating conditions are in line with section 3 before
initial and primed starting of pump.
Initial Start-Up
•
Complete the installation.
•
Check the inlet pipework is in contact with fluid to be
pumped
•
Do not run the pump dry for more than 30 seconds
•
Do not operate any switches with wet hands
Primed Start-Up
•
Check the inlet pipework is in contact with fluid to be
pumped
•
Do not operate any switches with wet hands
•
With flooded pump head, run dry duration is 20 minutes
(2000 model) and 10 minutes (3000 model) Do not exceed
these durations
Storage and Cleaning
•
Should viscous or potentially aggressive fluids be pumped,
it is recommended the pump be cleaned internally after
each use.
•
If the pump needs to be removed for storage purposes, it
must be stored in a cleansed condition in a cool dry location.
•
If storage is for longer than 3 months, a suggestion is to
remove the impeller. This will prevent a set being taken and
improve performance at startup
•
If storage is over a year, using a new impeller will guarantee
specified performance.
•
Pump units have been designed to meet IP55 standards and
can be pressure washed. Care should nevertheless be taken
to prevent wetting exposed electrical connections
