• The pump is installed in a safe and dry environment
• The pump enclosure has adequate drainage in the event of leakage
• Any transport plugs are removed
• The pipe-work is correctly sealed and supported
• The pump is primed correctly
• The power supply is correctly connected

please contact your Davey dealer or the appropriate Davey office as listed on the
back of this document.
Congratulations on your purchase of a high quality, Australian built Davey pressure
system. All components have been designed and manufactured to give trouble free,
reliable operation.
Your new pressure system incorporates ‘Presscontrol’, electronic flow controller that
enables the use of a highly efficient pump design and offers the following benefits:–
1. Enables the pump to deliver a constant flow of water particularly at low flow
rates – reducing the inconvenience of pressure variation in showers etc.
2. Provides automatic “cut-out” protection should the pump run out of water.
3. Provides warning indications for critical system faults.
1. Discharge Outlet (1” BSPM)
2. Presscontrol Module
3. Suction Inlet (1 1 /

” BSPF)
4. Pump Body
5. Motor
6. Rotary Coupling
7. Priming Plug
NOTE:
For protection, the Davey ® pump motor is fitted with an automatic “over
temperature” cut-out. Constant tripping of this overload device indicates a
problem e.g. low voltage at pump, excessive ambient temperature (above
50°C) in pump enclosure.
Care should also be taken when servicing or disassembling pump to avoid
possible injury from pressurised water. Unplug pump, relieve pressure by
opening a tap on the discharge side of the pump and allow any hot water in
the pump to cool before attempting to dismantle.
During servicing, use only approved, non-petrochemical based oring and
gasket lubrication. If unsure, consult your Davey Dealer for advice.
WARNING: Do not use hydrocarbon based or hydrocarbon propelled
sprays around the electrical components of this pump.
Before installing your new pump, please read all instructions carefully as
failures caused by incorrect installation or operation are not covered by the
guarantee. Your Davey pressure system is designed to handle clean water.
The system should not be used for any other purpose without specific
referral to Davey. The use of the system to pump flammable, corrosive and
other materials of a hazardous nature is specifically excluded.
NOTE: Prior to installation remove the red transport plugs from the suction and/or discharge.
In accordance with AS 3350.2.41 we are obliged to inform you that this
pump is not to be used by children or infirm persons and must not be used
as a toy by children.
