10.12 Separate control cabinet
For the "Flex" version, the control cabinet is delivered separately
for mounting on a wall or the floor. In this case, the controller
must be placed as close to the pump as possible and within view
of the pump set. The control cabinet must also be easily
accessible.
Fix the control cabinet to the wall with screws. Drill holes in the
wall according to the drawing on the back of the control cabinet.
11. Electrical connection
Check that the supply voltage and frequency correspond to the
values stated on the nameplate of the control cabinet.
12. Start-up
12.1 Preparations before start-up
1. Check that all screws are tight.
2. Check that all pipes and hoses are installed correctly.
3. Check all electrical connections.
4. Check that all fuses in the control cabinet are switched on.
5. Check the alignment of the coupling.
See section
10.5 Alignment
.
6. Check that all safety devices are installed.
7. Make sure that any storage tank and pump priming tank are
filled with water.
8. Set the pressure switches according to the instructions.
System pressure minus 0.5 bar can be used as a reference
value.
9. Fill the pump and suction pipe with water.
Unscrew the vent plug in the pump housing (pump with electric
motor), see fig. 28, or on the discharge side (pump with diesel
engine). Open the isolating valve on the suction side.
Fill water through the filling hole in the discharge pipe until
water runs out of the hole. Fit the plug and tighten it to 25 Nm
(1/2") or 30 Nm (3/8").

Caution
Warning
Make sure that water escaping from the pump or
pipework cannot damage the control cabinet.
The control cabinet is only intended to be
installed indoors and must not be exposed to
direct sunlight. Ensure sufficient ventilation for
the components in the control cabinet.
Warning
When drilling the holes, pay attention to electric
cables or water and gas pipework.
Warning
The electrical installation should be carried out
by an authorised person in accordance with local
regulations and the wiring diagram in the control
cabinet.
Warning
Switch off the power supply before making
connections.
Note
See installation and operating instructions for
the controller.
Warning
Start-up should be carried out by an authorised
person.
Warning
The control cabinet of the controller must remain
closed during start-up.
Caution
Do not start the pump until it has been filled with
water and vented.
Caution
The pump must not run against a closed valve as
this may cause an unacceptable temperature
increase or the formation of vapour.
Note
See also installation and operating instructions
for the controller.
Note
Pump set with Clarke diesel engine:
We recommend that you register the diesel
engine before start-up. Otherwise Clarke cannot
provide any warranty if the engine is faulty.
