Davey 165S SHALLOW WELL PRESSURE PUMPS & SYSTEMS - Manual (Page 6)

to check for correct operation as automatic pressure system
Close all outlet taps except one which should be turned on to allow small flow. Pump should build up pressure until it switches
off automatically at the cut-out pressure setting of the pressure switch (standard setting 380kPa, refer Table for others).
Pressure should then fall slowly as water flows from the one outlet tap until pump switches on automatically at cut- in setting of
pressure switch (standard setting 260kPa).
pressure switch
The pressure switch fitted to your Pressure Pump is required to function only if your pump is to operate automatically, in
conjunction with a Davey Supercell Pressure Tank.

(if applicable)
The standard operating pressure and respective pressure switch setting for each Model is denoted by an asterisk (*) in the
Table below. Performances at pressures higher than standard are obtainable by fitting alternative shallow well jet kits, and for
these installations it is necessary to reset the pressure switch according to the Table below. Instructions for altering the pressure
switch setting are under the cover of the switch itself.

*Standard configuration. NB: ‘psi’ figures are an approximation of the kPa figures.
WarnIng: do not use hydrocarbon based or hydrocarbon propelled sprays around the electrical
components of this pump.
*NOTE: For protection, the Davey pump motor is fitted with an automatic reset thermal overload, constant
tripping of this overload indicates a problem e.g. low voltage at pump, excessive temperature (above 50°C)
in pump enclosure.
WarnIng: Automatic reset thermal overloads will allow the pump to restart without warning. Always
disconnect the pump motor from the electrical supply before maintenance or repairs.
IMportant: DO NOT USE petroleum based fluids or solvents (e.g. Oils, Kerosene, Turpentine, Thinners,
etc) on the plastic pump components or seal components.
Care should also be taken when servicing or disassembling pump to avoid possible injury from hot 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.
WARNING: When servicing or attending pump, always ensure power is switched off and lead unplugged.
Electrical connections should be serviced only by qualified persons.
power connections and wiring must be carried out by an authorised electrician.
