Important Do's and Don'ts
1. DO check the incoming mains water pressure. The preferred range of mains
pressure is 2 -3 bar.
2. DO check the flow rate of the incoming cold water main is adequate to meet
the maximum hot and cold water simultaneous demands.
3. DO check that all connections are in accordance with the labelling on the
thermal store.
4. DO NOT push home the 2 switches on the isolating terminal connectors and
switch on the electricity supply until you have checked that the appliance is
full of water i.e. there is water in the top up cistern.
5. DO check the water level is correctly set in the top up cistern when cold and
if fitted that there is no overflow when the appliance is up to temperature.
6. DO check that the sensors switch the immersion heaters off at the correct set
point i.e. approx 70°C.
7. DO insulate any exposed hot water pipework in the PulsaCoil cupboard.
8. If the ballvalve in the F & E cistern is permanently connected to the mains
cold water supply 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).
9. DO ensure the green light 'on/off' switch glows.
10.Once the appliance is filled and commissioned DO leave the electricity
switched on to the appliance to ensure the automatic pump run facility can
operate to prevent the pump sticking.
11. DO ensure that the functioning and control of the system is explained to the
occupant.
12.DON'T place any clothing or other combustible materials against or on top
of this appliance.
These instructions should be placed along with the component
manufacturers instructions in the pocket provided on the rear of the
front panel. The front panel should then be refitted.
