6 COMMISSIONING
6.11
Isolate the booster set before pressure testing the system.
Over pressure could damage the pressure transducer and
diaphragm in the pressure vessel.
6.12
Each booster set is factory set to the required perameters
as per the agreed specification and per the operating
perameters set out elsewhere in this manual. We strongly
recommend that commissioning and service work is carried
out by the manufacturer’s personnel or appointed agents.
Please contact our technical sales department for information
on our commissioning and service contract packages.
6.13
System Flushing
The pipework system should be flushed out prior to the pump being
connected to ensure any contaminants/chemical residues and foreign
bodies are removed from elsewhere in the system.
6.14
Water supply:
Always ensure that water storage capacity is adequate to meet
the demand. Ensure the pump chambers are full of water before starting the
unit. Failure to do this could result in seal damage. To ensure dry running does
not occur the pumps must be primed as described in priming section below.
Do not run pump(s) dry
.
6.15
Priming:
Never operate the unit with inlet and/or outlet isolating valves
in the closed position. Damage will occur!
The pump’s must be primed (filled with
water) before starting.
(a) Turn on the service valves and vent/
prime pump head.
(a) Loosen priming plug on each pump
and allow an even flow of water this
may take a few seconds.
(b) Re-seal draining plug, nipping tight.
The pump is now ready to start.
6.16
Starting:
a) Ensure the pumps are vented and the water supply turned on.
b) Turn on the electrical supply at the isolator switch in the connection box.
c) The pump set will automatically start if the rA option (default setting) is selected.
If the pump set does not start press
button and the controller will start the
pumps.
