OMMISSIONING
INSTALLATION
Open the incoming stop valve and fi ll the domestic mains cold and hot water systems
including the PulsaCoil A-Class appliance.
Check the water level in the top up cistern and if a ballvalve is fitted adjust if
necessary.
Check the whole of the domestic hot and cold distribution systems for leaks. Fully
fl ush and if necessary chlorinate the hot and cold water system in accordance with
the recommendations in the Water Regulations and BS 6700.
Please note that the whole of the domestic hot and cold water systems including the
appliance must be adequately fl ushed after chlorination. Failure to do this can cause
damage to the plate heat exchanger/immersion heaters etc. If there are any doubts
regarding this or the quality of the water being used to fi ll the PulsaCoil appliance an
inhibitor such as Fernox MBI or Sentinel X100 should be added to the appliance when
fi lling in line with the manufacturers instruction for these products.
Check that the top up tank is fi lled up to the water level shown on the label. If it is a
manual fi ll model, this is most important.
If a ballvalve is provided, turn down the servicing valve once the system is fi nally
fi lled to the point where the warning/overfl ow pipe will cope with the discharge
arising from a ballvalve failure.
If an overfl ow is not provided ensure the temporary fi lling hose is isolated and
removed from its connection to the cold water supply.
It is essential that all systems function properly for optimum performance.
To achieve this the fl ow rate from each tap should be checked and a suitable number
of taps run simultaneously to check the impact of this on the fl ow rate at individual
taps.
We recommend that fl ow regulators are provided for each tap/terminal fi tting
to ensure that the available fl ow is shared evenly - See Appendix A for further
details.
Commissioning the PulsaCoil Control System
Once the PulsaCoil A-Class is fi lled with water, check the on/off switch on the front is
in the off position. The electrical supplies can then be switched on and the switches
on the two isolating terminal connectors can be pushed home.
WARNING - Pushing home these switches will complete the electrical circuit to the
immersion heaters. DO NOT PUSH HOME THESE SWITCHES AND SWITCH ON THE
ELECTRICITY SUPPLY UNTIL YOU HAVE CHECKED THAT THERE IS WATER IN THE F
& E CISTERN. Failure to do this can result in dry fi ring and premature failure of the
immersion heaters, which will invalidate the warranty.
Put the on/off switch on the front control panel
to the on position to activate the appliance
control board. The switch will glow green when
in the on position.
If an off peak supply is not available the on-
peak boost immersion heater will need to be
switched on by pressing the black button. The
red light will change to permanently on.
It can be checked that the boost immersion
heater is drawing current by use of a clamp
meter on the live supply when boost is active
or by interrogating the printed circuit control
board in accordance with the instructions in the
fault fi nding section of this manual.
The sensor control set points are shown on
page 25 and can be checked on the 2 digit ACB
display.
The boost immersion heater can be switched
off by pressing again the black button.
If an off peak supply is available at the time
the appliance is switched on the appliance will
automatically switch on the off peak immersion
heater. Its operation can be checked in the
same way as described above for the on peak
immersion heater. When the off peak supply
is available the on peak immersion heater
operation can still be checked as described
above by switching off the off peak supply.
Note: If the on and off peak supplies have been
connected wrongly (“crossed”) at the appliance
it will not operate properly (it may charge if off
peak is available but will not carry out any other
operations)
If the appliances has been connected with the
polarity incorrect it will not operate at all.
See the fault fi nding section of the manual for
further details.
Run a tap and using a digital thermometer
check that the temperature of the hot water is
about 52°C. This temperature is factory set and is
independent of the store temperature assuming
the store is above 55°C and typical hot water
fl ow rates of 6-25l/min are being drawn.
This product is covered by the ‘Benchmark’
scheme and a separate commissioning/
service log book is included with this
product. This must be completed during
commissioning and left with the product
to meet the Warranty conditions offered by
