Congratulations on your purchase of a quality product from the Davey range of
Pool and Spa Equipment. You are assured of many years of reliable and efficient
performance from your Davey PowerMaster backed by Davey's three year
guarantee.
Davey PowerMasters have been designed to circulate swimming pool and spa water
in conditions set out in the Australian Standard for swimming pool water quality (AS
3633) or equivalent. They should not be used for any other purpose without first
consulting your Davey Dealer or the Davey Customer Service Centre.
Davey design and build its own electric motors especially for its pumps. The
matched motor and "pumping end" are designed to provide the quietest operation
while delivering maximum water flow.
Davey's totally enclosed fan-cooled motor incorporates "autostart" overload
protection with a built-in automatic thermostat designed to protect the motor from
overheating.
Every Davey PowerMaster is thoroughly water tested against a number of flow,
pressure, voltage, current and mechanical performance parameters. Davey`s
advanced pump manufacturing technology provides reliable and efficient pumping
performance that lasts and lasts.
Location
The pump should be located as close to the water as practicable and mounted on
a firm base in a well drained position, high enough to prevent any flooding. It is the
installer's/owners responsibility to locate the pump such that the nameplate can be
easily read and it can readily accessed for service.
Weather Protection
It is recommended that the pump is protected from the weather. Enclosures should
be ventilated to prevent condensation build-up and allow a free flow of air for the fan
cooled motor.
Power Connection
Davey PowerMaster's are suitable for connection to a nominal 240 (for 415 volt refer
to page 7) volt 50Hz power supply and are equipped with a flex and 3 pin plug. If
a power outlet is not available within 3 metres of the pump, a 3 pin power point in
a safe, dry place, may need to be provided by an electrician. Extension cords are
unsafe around pools - and should be avoided. If the supply cord of this product is
damaged it must be replaced by the Dealer or manufacturer, with genuine Davey
spares.

Davey Water Products recommends that all installations are fitted with
earth leakage or residual current protection devices.
CAUTION: In the interest of safety, we advise that all brands and types of
pool pumps must be installed in accordance with AS3000 wiring rules or
equivalent.
This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience
and knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the
appliance.
If the pump and filter are located below pool water level, it is necessary
to fit isolating valves in the pipe between the pump and the skimmer box
and in the return pipe from the filter to the pool.
The fittings on this product are constructed of ABS. Some PVC jointing
compounds are incompatible with ABS. Check compound suitability
before use.
NOTE: PowerMaster Pool Pumps are fitted with an internal check valve to reduce
reverse flow of water through the pump.
Warning! Ensure that an electrical isolation switch is located with easy
access so that the pump can be switched off in an emergency.
Pipe Connection
A barrel union is provided for connecting to the piping from the pool.
The pumps are designed to accept the following PVC Pipes:
Model Inlet PVC
PM200/250 40mm pipe
or 50mm fitting
PM350 40mm pipe
or 50mm fitting
or 50mm pipe
PM450 50mm pipe
The use of any pipe smaller than those specified above is not recommended.
Suction piping should be free from all air leaks and any humps and hollows which
cause suction difficulties.
The discharge piping from the pump outlet should be connected to the inlet
connection on the swimming pool filter (usually at the filter control valve).
Barrel unions need to be hand tightened. No sealant, glues or silicones are
required.
