Davey Dynapond Pond Pump - Manual (Page 2)

Installation & operating Instructions
The Davey Dynapond Pumps are suitable for clean water for ponds, waterfalls, Koi tanks, fish farms, recirculating
applications etc.
They are extremely quiet in operation which makes them ideal for applications within residential areas.
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 Davey Authorised Service Dealers.
suitable Fluids
This pump is designed to pump clean pond water, which may contain limited amounts of soft solids up to 10mm
diameter. Water temperature must not exceed 35 o C. 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 application, contact your Davey dealer for
advice.
Installation
This Davey pump is completely submersible up to 3 metres and should be placed on a solid flat surface (if not
available, sit the pump on timber or house bricks) in either the vertical or horizontal 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 ponds, connect a rope to the handle during
installation.
strainer adjustment / removal
Your Dynapond Pump is fitted with a strainer with adjustable inlet hole size (see illustration 1). By rotating the strainer
slightly clockwise the hole size is reduced to 5mm, counter-clockwise increases the hole to 10mm.
The strainer can also be removed for cleaning. Turn the strainer to the central position as shown in the illustration 2,
allowing the four locking tabs in the centre of the strainer to be pushed outwards. The strainer can then be removed
to allow for cleaning and maintenance. DO NOT OPERATE THE PUMP WITHOUT THE STRAINER!
Motor cooling
Dynapond pumps rely upon water flow around the motor shell for correct motor cooling. Do not operate the pump
without flow through the pump.
Dynapond pumps are only suitable for fully submerged operation.
Power connection
A power connection point should be provided by a qualified electrician, in compliance with the requirements of
Australian/New Zealand wiring rules AS 3000 (2000). Dynapond models are rated for 220/250 Volts, 50Hz operation,
and may be connected to a standard 10 amp power outlet.
Dynapond 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 15 to 20 minutes.

Fault checks
a) Pump will not start:
 Check to ensure power is available and the outlet is switched ON.
 Blown fuse or tripped circuit breaker (replace/reset or call an electrician).
 If an extension lead is fitted, check connection.
 Impeller jammed - disconnect from power supply, and ensure impeller is free to rotate.
 Thermal cut-out switch has not reset (wait 15 to 20 minutes).
B) Pump runs, but does not pump water or pumps insufficient water:
 Pump not submerged.
 Strainer, impeller and/or discharge pipework blocked.
 Impeller damaged.
 Air lock in discharge pipework. Ensure pump is filled with water.
 Excessive back pressure or lift.
c) Pump will not stop:
 Must be switched off at the power supply.
D) Pump runs for short periods only (the overload protection has tripped):
 Some foreign body is clogging the impeller.
 The liquid temperature is too high.
 Pump operating in non submerged position.
 Electrical fault.
Do not run the pump dry as this will damage the seal and reduce the life of the pump.
The pump should be regularly checked. It might become necessary sometimes to clean the suction strainer, impeller
and/or discharge pipework.
With simple cleaning and regular examination this pump will give long and reliable service.
Do not:
run the pump dry.
Attempt electrical repairs, unless qualified to do so.
Run the pump with the motor fully or partially exposed.
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.
BeFore startIng tHe PuMP, VerIFY tHat:
- the electric circuit is equipped with an automatic residual current device rated at 30 ma with
correct earthing.
- the voltage and frequency shown on the technical nameplate of the pump correspond to the
data of the electric supply system.
- the power cable of the pump is not damaged.
- The electric connection must be done in a dry, safe place, free from possible flooding.
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.
under no circumstances may this pump be used in a swimming pool or spa bath.
WarnIng: When servicing or attending pump, always ensure power is switched off and lead un-
plugged. Electrical connections should be serviced only by qualified persons.

note:
1. Long extension leads should be avoided as they often have insufficient current carrying
capacity to run electric motors, hence they can cause substantial voltage drop and operating
problems.
2. Minimum voltage at the electric motor must not fall below 216 Volts for single phase, other-
wise motor damage may result which is not claimable under guarantee.
3. If the electrical fittings in your country make it necessary to remove the plug from the lead
fitted to the motor, care should be taken to ensure that the earth conductor green/yellow in
the lead is properly connected to a good earth. this work should be undertaken by a suitably
qualified person.
During servicing, use only approved, non-petrochemical based oring and gasket lubrication. If
unsure, consult your Davey dealer for advice.
note:
If fitting an extension lead a QUALIFIED ELECTRICIAN should be consulted to ensure correct rat-
ing is provided. Extension leads are not allowed for permanent installations.
