Pipe Connection - Davey Silensor Installations- Und Betriebsanweisungen

When the unit is connected and operating the phase balance should
be checked. This should be within 5% variation. "Rolling" the leads
may help to improve a small unbalance, but major phase unbalance
will usually be attributed to an input power unbalance. This must be
addressed before the pump is used.

Pipe Connection

A set of applicable (European or Australian) barrel unions are provided for connecting to the
piping from the pool.
The pumps are designed to accept the following PVC pipes by fitting the pipe to either the
inside or the outside of the union tail.
Model
SLS100-300
SLL150/200/2003F
SLL300/400

The use of any pipe smaller than those specified above is not recommended. Suction piping
should be free from all air leaks and any humps and hollows which cause suction difficulties.
The discharge piping from the pump outlet should be connected to the inlet connection on the
swimming pool filter (usually at the filter control valve).
Barrel unions need to be hand tightened. No sealant, glues or silicones
are required.
