Pipe Connection; Starting The Pump - Davey SILENSOR SLS100 Installations- Und Bedienanleitung

8. Carefully fit wiring and terminal block back in to the capacitor housing, ensuring that all wires are housed
so that the rear cover doesn't pinch the wires when fitted
9. Replace rear pump cover and fasten with nut and washer.
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 Inlet PVC
SLS100-300 1.5" pipe
or 2" fitting
SLL150/200 1.5" pipe
or 2" fitting
or 2" pipe
SLL300/400 2" pipe
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.

Starting the Pump

To operate efficiently and prevent pump damage there must be a free flow of water to and from the pump.
Before starting ensure that:
- all pipework is correctly sealed.
- the pool/spa water level is at the correct height.
- that all appropriate valves are open and there is nothing preventing the flow of water through the system.
1. First prime the pump by removing the strainer basket lid and filling the strainer basket area with water.
Replace the lid, ensuring that it seals on the large oring.
2. Connect to the power supply and switch on.
3. Allow the pump to run, so that any air trapped may be expelled.
4. If prime is not established within approximately two minutes, as evidenced by a strong flow of water,
switch off the pump and repeat the procedure. Continued evidence of air under the strainer basket lid
indicates an air leak in the suction piping which should be rectified to avoid pump damage.
