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 well-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.
5.BASE
Fix the pump in place through the footplate using suitable fasteners, on a stable, level surface – must NOT be sloping even slightly.
6. IMPORTANT re PUMP NOISE:
DO NOT install near bedrooms or neighbours bedrooms. These are TURBINE pumps and due to their design
they typically make more noise than a JET or 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.
7. (a) PIPE SIZE AND TYPE:
Install the pump as near the water supply as possible to reduce the length of suction pipe. We recommend heavy
duty flexible suction hose for the inlet (Suction Pipe) but whatever pipe is used it must be no less than 25mm Internal Diameter (30mm is
better), and heavy-duty pressure hose or similar for the outlet, we recommend 25mm Internal Diameter for the delivery pipework for the best
performance, 19mm Internal Diameter minimum for the discharge. Use as few bends as possible, every bend reduces performance.
7. (b) MORE INFO RE PIPE SIZE:
Pressure of the water at the discharge (taps etc) is affected by the pipe size. The SMALLER your pipes, the
LOWER the pressure will be at discharge. Example: 13mm ID pipe over 20 metres at 30Lpm will reduce pressure at discharge by 240kPa
(2.4bar) - whereas if 25mm ID pipe is used for 20 meters at 30Lpm it only reduces pressure by a miniscule 10kPa. Smaller pipe also means that
more power will be used as the pump has to work harder to overcome the extra back-pressure from small pipes. A small short-term saving (in
the cost of the pipes) will become a long-term liability.
8.SEAL JOINTS
Ensure all fittings and joints are watertight and airtight, especially in suction-lift applications.
9. INSTALLATION AND ELECTRICAL WIRING
must adhere to state and local codes and must be completed before priming the pump. These
pumps come with an earthed power plug and all electrical installations must be earthed. Any Electrical work must be performed by a licenced
Electrician. The installation must also comply with applicable Plumbing Regulations; it is the installers responsibility to ensure compliance.
10. IMPORTANT re SAFETY SWITCH (RCD);
(a) The Pump must be connected to a suitable power circuit with an integral RCD (safety switch) having a rated residual operating current not
exceeding 30mA, in the circuit breaker. Disconnect the pump from power supply when people are in the water, or when servicing or repairing
the pump. All warranty is void if this instruction is not followed. Note: Plugging into existing outlets may cause low voltage supply to the
motor, causing blown fuses, tripping of motor overload, or burnt out motor, which will not be covered by the Warranty.
(b) Surge Protection - We recommend that a surge protector is used to protect the electronics of this pump, as damage due to power surges is
not covered by the Warranty.
11. MAINS PRESSURE BOOSTING
The DT42 Pump is not recommended for this type of application. It is a specialized type of application, and
must be completed by a Qualified Plumber or Pump Technician who is competent and licenced to perform this type of installation.
12. VOLTAGE
of power supply must match the voltage of the pump – refer to the nameplate on the pump. Do not run on generator power
from low quality/old generators. If you only have generator power, you may need to have the Pressure Controller removed and replaced with
a Pressure Tank and Switch, at additional cost. The Pressure Controller will be damaged by the voltage fluctuations caused by power supplied
by low quality generators. High quality “Sine-Wave” generators are usually acceptable but we cannot guarantee this, as we have no control
over the generator that you use, it is your responsibility to ensure the generator used is fit for the purpose.
13. WARNING:
these pumps are not designed for, and must not be installed in locations classified as hazardous.
14. THE FOLLOWING MAY CAUSE SEVERE DAMAGE TO THE PUMP AND WILL VOID WARRANTY;
(a) Using an extension cord to power the pump.
(b) Cutting the earth pin off the plug or using an adapter fitting or double adapter.
(c) Working on the pump while connected to the power supply.
(d) Removing motor housing, or dissembling the pump housing, except by a qualified technician
(e) Pumping chemicals or corrosive liquids or flammable liquids.
(f) Pumping hot liquids (Exceeding 40° Centigrade)
(g) Using a generator for power supply - see 12
(h) Operations that involve frequent starting. This will lead to premature failure of the capacitor. We recommend that if the pump is regularly
starting more often than 10 times per hour, you should add a pressure tank into the system. Occasional frequent starting is not a problem, but
constant (most of the day) frequent starting is a problem. Note that if the pump starts and stops more than 7 times within 2 minutes, it may
switch itself off and you will need to press the restart button to reactivate it.
15. PUMP PRIMING AND START UP
(a) Dry operation will destroy the pump seals and is not covered by warranty.
(b) Remove the pressure controller by loosening the barrel union, (or use the priming plug at the front of the wet-end, near the inlet, but that
is slower) and completely fill the pump chamber with water before starting.
(c) Turn the pump on, if water does not flow, turn it off and repeat step 15(b) again, and if it is suction-lift the entire suction pipe may need to
be pre-primed (refer to 16. For further information re suction lift)
(d) If it still does not pump water, check the intake and discharge pipework is free from airlocks, or any other obstructions and refer to the
TROUBLESHOOTING guide.
