1. YOUR DAVEY SILENSOR
Congratulations on your purchase of a quality
product from the Davey range of Pool and Spa
Equipment. Davey Silensor pool pumps have been
designed to circulate swimming pool and spa water
in conditions set out in the Australian Standard for
swimming pool water quality (AS 3633), or local
equivalent. They should not be used for any other
purpose without first consulting your Davey retailer,
or the Davey Support Centre. For contact details,
please consult the back page of this manual.
Davey design and build its own electric motors
especially for its pumps. The matched motor and
"pumping end" are designed to provide the quietest
operation while delivering maximum water flow.
Davey's innovative water cooled motor incorporates
manual overload protection with a built-in automatic
thermostat designed to protect the motor from
overheating. This protection will also prevent 'dry
run' damage. Every Davey Silensor pool pump is
thoroughly tested against a number of pressure,
voltage, current and mechanical performance
parameters. Davey`s advanced pump manufacturing
technology provides reliable and efficient pumping
performance that lasts and lasts.
2. LOCATION
The pump should be located as close to the water
as practicable and mounted on a firm base in a
well drained position, high enough to prevent any
flooding. It is the installer's/owner's responsibility
to locate the pump such that the nameplate can be
easily read and the pump can be readily accessed
for service.

1. Do not install 90° elbows directly into pump inlet.
Elbows should be no closer than 250mm to the inlet.
2. Flooded suction systems should have gate valves
installed on suction and discharge pipes for
maintenance, however, the suction gate valve
should be no closer than 250mm from the inlet.
3. Use a check valve in the discharge line when
using this pump for any application where there is
significant height to the plumbing after the pump.
4. Be sure to install check valves when plumbing in
parallel with another pump. This helps prevent
reverse rotation of the impeller and motor.
