Installation & Operating Instructions
The Davey range of Submersible Sump Pumps are suitable for small to medium Dewatering (or recirculating)
applications. Vortex models are suitable for pumping small soft solids in fluid suspension. The multi impeller D42 & D53
models are designed for clean water only.
They are extremely quiet in operation which makes them ideal for applications within residential areas for sullage pits,
waterfalls and general drainage.
Other Ideal Applications are:
Lift Wells, Car Park Sumps, Basements, Cable Pits, etc.
This Submersible pump has been factory checked prior to delivery; however, please check for any damage during
transport. After Sales Service is available from Davey or Special Davey Authorised Service Dealers.
Suitable Fluids
This pump is designed to pump waste water, clean water and water containing mild pollutants at ambient temperatures. It
is
not suitable
for pumping flammable or corrosive fluids, nor fluids at elevated temperatures. If you are unsure as to the
suitability of the fluids, contact your Davey dealer for advice.
The multi impeller D42 & D53 are designed for clean water only.
Installation
This Davey pump is completely submersible up to 10 metres and should be placed on a solid flat surface (if not available, sit
the pump on timber or house bricks) in the vertical position. Pump should always be installed so that it will be clear of settled
silt or debris. It is recommended to fit the biggest diameter hose possible, to obtain the best flow from the pump. To remove
or lift the pump from deep wells or pits connect a rope to the handle during installation. Automatic versions should be placed
in a sump which has adequate dimensions so as not to restrict the movement of the float switch.
Automatic controlled pump units have float switches factory set to provide the correct high (ON) and low (OFF) liquid levels.
Motor Cooling
All models rely upon water flow around the motor shell for correct motor cooling. DC & RS models have a double case
which forces water around the motor. These models are therefore suitable to operate partially submerged.
All models other than the double case models are suitable for partially submerged operation only for short periods up to
10 minutes.
Where the pump (other than double case models) is required to operate for longer than 10 minutes partially submerged,
or where water flow over the motor may not be assured, it is advisable to direct a low flow (2-3lpm) cooling jet of water
over the motor shell (eg. when installed in large tanks or ponds).
Power Connection
A power connection point should be provided by a qualified electrician, in compliance with the requirements of AS 3000
(1991). Single phase models are rated for 220/250 Volts, 50Hz operation, and may be connected to a standard 10 amp
power outlet.
All single phase models have automatic reset thermal overload protection built in, ie. should overload on motor cause
thermal to open circuit and switch motor off, it will automatically reset and switch the motor on when the motor has cooled
down sufficiently, usually within a few minutes.
DO NOT:
Run the pump dry.
Attempt electrical repairs, unless qualified to do so.
Run the pump with the motor fully exposed for long periods.
Install the pump on soft or loose ground.
Operate the pump if the inlet is submersed by sand or debris.
Lift or carry the pump by the power cable.
This pump is not a slurry pump, it is not designed to pump hard solids (eg stones) nor fluids containing
excessive amounts of abrasive materials.
Not intended to be used for swimming pool. Note that these pumps may be used for the repair or maintenance
of swimming pools, but never with people present in the water.
NOTE:
If the cord is damaged, the appliance should be repaired by a qualified Davey Service Centre. The supply cord
must only be replaced by a suitably qualified person with a genuine Davey replacement supply cord.
