2.2
COMMISSIONING
The unit should only be commissioned by a competent person;
A competent person is someone who is technically
competent and familiar with safety practices and the hazards involved
.
2.2.1
READ GENERAL SAFETY INFORMATION 0.0, WARNINGS 0.1 and CAUTIONS 0.2, 0.3 & 0.4. plus the
additional warnings and cautions 1.1 & 1.2
2.2.2
This pumpset has been tested in the factory prior to delivery. However, it is impossible to simulate the
actual on‐site conditions, especially if they are unusual. Therefore we can (if required)
commissioned
the pumpset
, make any necessary adjustments and leave the set in operational order. Please see
contact information at the end of this manual.
2.2.3
Should you wish to commission the pumpset yourself, then please follow the instructions below: You
must ensure that;
2.2.3.1
the equipment has been correctly installed;
2.2.3.2
a written scheme of examination has been obtained where required under the Pressure Systems
Safety Regulations;
2.2.3.3
any necessary chlorination or other treatment has been completed;
2.2.3.4
the system pipework has been thoroughly flushed prior to final connection of the pumpset to ensure
any contaminants/chemical residues and foreign particles have been completely removed;
2.2.3.5
an adequate water supply (1 to 3Bar) and permanent electricity supply (230vac 1 phase 50Hz 6 Amp)
are available;
2.2.3.6
the pipework etc in the building being served by the pumpset is capable of accepting the generated
pressures.
2.2.4
with the power and water OFF, check tightness of all mechanical and electrical connections, to ensure
they have not loosened during transit.
2.2.5
with the pumpset switched off (IS1) and the motor circuit breaker switched off (CB1), close the
discharge isolating valve.
2.2.6
close the mains water inlet isolating valve, check and clean the strainer, re‐install strainer ensuring it is
leak free.
2.2.7
check the control vessel air charge is correct (1.3Bar) when there is no pressure on the discharge.
2.2.8
check and clean pump suction strainer/inlet filter (See Fig 2.1)
2.2.9
slowly open mains water inlet valve, switch on unit to allow solenoid valve to open and fill the mains
water break tank.
2.2.10
ensure the pump is primed (filled with water) before starting otherwise the pump seal will be
damaged and cause it to leak (see fig 1.1a).
2.2.11
once the pump is fully primed, switch the pump motor circuit breaker (CB1) on and allow the pump to
pressurise against the closed discharge valve. The pump should stop when closed valve pressure has
been achieved (plus a short run on time).
2.2.12
ensure all system outlets are closed, SLOWLY open the pumpset discharge valve to allow the pump to
pressurise the system pipework. Check for leaks and repair them.
2.2.13
open and close each system outlet in turn allowing water to flow from each outlet until all the air is
purged. As each outlet is opened and closed the pump should start and stop (stops after a short time
delay).
2.2.14
if any outlet on the system is opened and closed this should cause the pump to start and stop and the
breaktank to refill as necessary. If this is so then the pumpset is working normally.
2.2.15
check for normal operation and that no leaks are present, check all isolation valves on the pumpset
are open and all covers are fixed in place before leaving the installation unattended.
