Weather Protection
It is recommended that the pump is protected from the weather.
Power Connection
Davey QB Series are suitable for connection to a nominal 240 volt 50Hz power supply and are
equipped with a flex lead and 3 pin plugor AMP plug to allow connectability to a Davey Spa
controller. If a power outlet is not available within 3 metres of the pump, a 3 pin power point
in a safe, dry place, may need to be provided by an electrician. Extension cords are unsafe
around pools or spas - and should be avoided. If the supply cord of this product is damaged it
must be replaced by the dealer or manufacturer, with genuine Davey spares.
Pipe Connection
A set of barrel unions are provided for connecting to the piping from the spa or pool.
The pumps are designed to accept 50mm PVC pipes by fitting the pipe to the inside of the
union tail.
The use of any pipe smaller than 50mm PVC pressure pipe not recommended. Suction piping
should be free from all air leaks and any humps and hollows which cause suction difficulties.
The suction and discharge pipe should have a constant gentle slope of at least 2% to facilitate
adequate purging of air.
If the pump and filter are located below pool water level, it is necessary to
fit isolating valves in the pipe between the pump and the skimmer box or
suction inlet and in the return pipe from the filter to the pool.
Warning! Ensure that an electrical isolation switch is located with easy
access so that the pump can be switched off in an emergency.
CAUTION:
In the interest of safety, we advise that all brands and types of spa pool
pumps must be installed in accordance with AS3000 wiring rules or equivalent
Davey Water Products recommends that all installations are fitted with
earth leakage or residual current protection devices.
This pump is not to be used by children or infirm persons and must not be
used as a toy by children.
Barrel unions need to be hand tightened. No sealant, glues or silicones
are required.
