Davey HM Series Electric Pumps - Manual (Page 3)

Choosing a Site
Choose a site with a firm base as close to the water
source as possible with correct power supply. Make sure
your pump is always connected to an adequate, reliable
source of clean water.
Housing your Davey Pump
To protect your pump from the weather, make
sure the pump house is both water proof, frost
free and has adequate ventilation.
The pump should be mounted on a firm base
allowing for drainage, to avoid damage to
flooring etc., that over time may occur from
leaking pipe joints or pump seals. Do not mount
the pump vertically. Never place flammable
materials on or near your pump.
Power Connection
Single Phase
The single phase models which are supplied with a 10 amp plug may be plugged
into a standard 10amp outlet. Model with the special 15 amp power plug may only
be used with the appropriate 15 amp 220/250V power outlet (15 amp power outlets
are usually specially provided by an electrician).
Always ensure that the earth conductor in the lead is connected to a good earth.
All single phase Models have automatic re-set thermal overload protection built
in, i.e. should overload on motor cause thermal to open circuit and switch motor
off, it will automatically re-set and switch motor on when motor has cooled down
sufficiently, usually within a few minutes.
The electrical connections and checks must be made by a qualified
electrician and comply with applicable local standards. Poor installation
or poor power supply may even result in electrical fires!
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.
NOTE:
1. Ensure motor is connected to power supply specified on nameplate.
2. Avoid long extension leads as they can cause substantial voltage drop
and operating problems.
3. Although the Davey electric motor is specifically engineered to perform
on a range of power supply voltages, malfunctions or failure caused by
adverse voltage supply conditions are not covered under guarantee.
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.

*NOTE “MOTOR PROTECTION DEVICE” :
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: When servicing or attending pump, always ensure power is
switched off and lead unplugged. Electrical connections should be serviced
only by qualified persons.
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.
WARNING: Do not use hydrocarbon based or hydrocarbon propelled
sprays around the electrical components of this pump.
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.
IMPORTANT:
DO NOT USE petroleum based fluids or solvents (e.g. Oils, Kerosene,
Turpentine, Thinners, etc) on the plastic pump components or seal
components.
