INSTRUCTION MANUAL & WARRANTY EXTERNAL CONSTANT PRESSURE
PUMPS
APPLICATION: CONSTANT PRESSURE PUMPS are fit for purpose when installed correctly according to these instructions;
For pumping of Clean Fresh Water at a temperature of +5°C to +40°C to: Garden Taps, Houses, Sheds, Cabins, Pressure Boosting,
Clean Water Transfer, suitable Rain-to-Mains Systems (370Watt and greater motor size) and for no other use. They must not be used
in hazardous locations or for liquids other than clean water, or for continuous operation.
DANGER: DO NOT INSTALL ANY PUMP if the premises does not have a Safety Switch (RCD)
IMPORTANT:
Ensure the pump is the right size for your application, before you install it. A pump that is under-sized is not faulty, and is
not covered by warranty. Ensure the right size piping is used, small pipes reduce performance and cause the pump to use more power!
See below for further information, and refer to the information on the box and/or label on the pump for the performance data. If in
doubt consult with your dealer or a pump technician to ensure your pump is sized to suit your needs.
PERFORMANCE DATA
Refer to the information on the box.
NOTES: Performance data quoted is generally from test data, and can vary, and does not take into account factors in the installation
such as loss of pressure and flow due to pipework & pipe-fittings & valves. Product depicted on the box and referred to in this
document, and other diagrammatic instructions, may differ from the product supplied, due to design changes or improvements.
***Be aware that the Amps and Wattage will vary according to the load on the motor, the figures stated are approximate.
INSTALLATION GUIDELINES
Please read and follow the instructions including the diagrammatic instructions. Warranty is voided if the instructions are not followed.
1a.
IMPORTANT MANDATORY REQUIREMENTS FOR ALL INSTALLATIONS:
Before installing or servicing disconnect from the power
supply. All pumps must be installed using barrel-union connections to facilitate easy servicing or replacement. Ball-valves or gate-
valves must be fitted on the suction, and the discharge, and the Town-water backup supply where fitted. A Y-Strainer or Pre-filter must
be installed on the suction to prevent particles entering the pump. Remove all swarf from the tank after cutting openings etc – swarf in
the pump voids warranty. All instructions are conditions of warranty; all warranty is void if instructions are not followed.
It is recommended to install a Check-Valve in the discharge pipework, however DO NOT install the check valve directly on the discharge
of the Pressure Controller, as this may cause it to malfunction, install the Check-Valve further down the pipe, before the first point of
discharge.
1b.
IRRIGATION USE - MANDATORY REQUIREMENTS FOR ALL INSTALLATIONS:
For any installation of these pumps that is supplying
irrigation, you must fit an 18L or larger pressure tank. Air pressure must be set at 70% of maximum pump pressure. Tank is simply fitted
to the discharge pipework with a “tee”, anywhere between the pump and the first point of discharge.
2. POSITION
Do not position the pump where it could take in solids or sludge. This pump is not to be used as your sole water supply.
For critical applications where loss of water supply could cause serious consequences, use a DUAL PUMP System so you have a second
water supply or use a TOWN-WATER BACK-UP SYSTEM. This pump is not designed for Fire Fighting purposes.
3. PROTECT FROM THE WEATHER:
The pump must be protected from the weather, by way of a plastic pump cover or skillion roof
cover, or similar. However the installer must ensure that there is adequate ventilation so the pump does not overheat.
4. IMPORTANT re INSTALLATION:
This pump MUST NOT be installed in any manner that if it were to leak that it would cause damage
or loss to property or persons. It MUST be installed in a well-ventilated and drained area. All warranty is void if this condition is not
heeded and no liability can be accepted in the case of damage or loss caused by failing to comply with this condition. If the pump
leaks, the water must be able to drain away from the pump and not cause damage.
DANGER!!!!
If water pools around the pump (from any source of water) it will cause a dangerous electrical hazard.
5. BASE must be LEVEL
Fix the pump in place through the footplate using suitable fasteners, on a stable, level surface – the base must
NOT be sloping even slightly – ensure it is level.
6. IMPORTANT NOTE re PUMP NOISE:
Avoid installing pumps near bedrooms or neighbours bedrooms. Particularly JET pumps, due
to their self-priming design they typically make more noise than a MULTISTAGE Pump. This is a feature of the pump design, it is not a
fault, and is not a cause for warranty claims, as it is not a product fault. If noise is likely to cause problems, we recommend that you use
a MULTISTAGE Pump, and install the pump AWAY from bedrooms.
