VARIABLE SPEED CONTROL
The variable speed control
(fig.11)
can be
adjusted to select the optimum performance of
the pump to suit personal preferences.
COMMISSIONING
Before the first operation of the shower pump, it
is necessary to flush out any system debris from
the installation. This operation must be carried
out with the pump isolated from the electricity
supply, and with the pump feed pipework from
the cistern and cylinder directed to waste by
connecting a suitable length of hose.
Procedure
1
Ensure the isolating valves from the cistern
and cylinder are closed.
2
Turn on the mains water supply to the
storage cistern and allow the cylinder and
system to fill.
3
Open both isolating valves and flush
through thoroughly.
4
Allow water to flow to waste for two or
three minutes to ensure any installation
debris and air is completely flushed from
the system.
5
Check the system pipework for leaks.
6
Close both isolating valves. Remove the
waste hoses and connect the cistern supply
pipework and cylinder pipework to the
pump inlet flexible push-in connectors.
7
Remove the sprayhead from the mixer valve
hose and direct the hose to waste.
8
Open the mixer valve fully and then re-open
both isolating valves.
9
Allow water to flow under gravity from the
hose for a few minutes.
10
Stop the flow at the mixer valve.
11
Switch on the mains electricity supply to the
shower pump.
12
Open the mixer valve. The pump will
operate and water will flow. Allow water to
flow to waste for two or three minutes.
13
Check system pipework again for leaks.
14
Turn off the mixer valve – the pump will
switch off and the water will cease to flow.
Replace the sprayhead onto the shower
hose.
