The system shall be filled, flushed and sterilised in
accordance with the requirements of BS 6700 and the
Model Water Byelaws.
The flow rate from each tap shall also be checked and a
suitable number of taps run simultaneously to check the
impact of this on the flow rate at individual taps.
We do recommend that flow restrictors are provided on
the branch to each tap/terminal fitting to ensure that the
available flow is shared evenly - see Appendix for details.
COMMISSIONING
THE APPLIANCE
The PulsaCoil III shall be filled with mains cold water
through the F and E cistern lid until the level is in line
with the swage mark provided in the cistern. The lid
shall be replaced.
Once the PulsaCoil III is filled with water the electrical
supplies can be switched on.
The control panel on the front of the appliance is provided
with two green indicator lights and a reset button as
follows:-

Green light No.1 is linked to the flow switch and should
be ‘on’ to show there is sufficient water in the F and E
cistern.
Green light No.2 is linked to the overheat thermostat and
should be ‘on’ to indicate the system is functioning
correctly.
The overheat button should be ‘pressed in’.
If this is the case the immersion heaters should be allowed
to bring the contents up to temperature. Check that the
thermostats do switch off at the correct temperature of
77
0
C. If not the seal can be broken and the setting
adjusted without affecting the warranty.
If the thermostats do not switch off the immersion heaters
at the correct temperature the overheat thermostat will
operate the overheat manual reset button. In this case
check and adjust the immersion heater thermostats or
replace if necessary and reset the overheat button.
Once the immersion heaters have switched off run a tap
and check that the temperature of the hot water is about
55
0
C. This temperature is factory set and is independent
of the store temperature and hot water flow rates.
a)
DO
check the incoming mains water pressure. The
preferred range of mains pressure is 2 – 3 bar.
b)
DO
check the flow rate of the incoming cold water
main is adequate to meet the maximum hot and cold
water simultaneous demands.
c)
DO
check that all connections are in accordance
with the labelling on the thermal store.
d)
DO
check the water level is correctly set in the F &
E cistern when cold and adjust if necessary.
e)
DO
ensure that the immersion heater thermostats
are set to 77
o
C.
f)
DO
insulate any exposed pipework in the PulsaCoil
cupboard.
g)
If provided
DO
plumb the overflow/warning pipe in a
20mm internal diameter pipe and ensure it discharges
in a conspicuous external position. Use a material
which is suitable for use with heating F & E cisterns
in accordance with BS 5449 (such as copper).
h)
DO
ensure the 2 green lights are ‘on’ and the manual
overheat reset button is pushed in.
