Power connection
A power connection point should be provided by a qualified electrician, in compliance with the requirements of AS 3000
(1991).
Single Phase
Single phase models are rated for 220/250 Volts, 50Hz operation, and up to 750 Watt may be connected to a standard 10
amp power outlet. 1500 Watt models may be connected to a 15 amp power outlet.
All models have automatic reset thermal overload protection built in, i.e. should overload on motor cause thermal to
open circuit and switch motor off, it will automatically reset and switch motor on when motor has cooled down sufficiently,
usually within a few minutes.
three Phase
Three phase models are rated for 380/440 Volts, 50Hz operation. all three phase models must be wired in by an
authorised electrician. If used in conjunction with a contactor we suggest the installation of correctly set additional quick
trip or M10 rated overloads.

1. Re-check the nameplate for the correct voltage and frequency
2. Check the wiring, power source and the capacity of the earth leakage protector and the insulation resistance of the
motor.
* Reference value of resistance = 20MΩ min.
3. When used with a generator, limit the number of appliances used on the generator at the same time.
Test run the pump for a short very period (1 second or less) to check direction of rotation. This can also be checked with
a phase rotation indicator.
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.
Power connection
connect lead to power supply designated on pump label. do not use long extension leads as they cause
substantial voltage drop, poor pump performance and may cause motor overload.
to avoid damage to the pump and any power leakage, which could result in electric shocks, please ensure that
the grounding has been properly installed and checked.
Incorrect voltage or frequency of the power source can lead to incorrect functioning of the pump, power leakage
or prove to be a fire hazard.
The reference no. of 20MΩ min is based on a new or recently refurbished pump unit.
never run the pump when hanging from a chain or cable, where the starting torque may cause the pump to move
and cause injury.
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.
