USING THE UNIT
COMMISSIONING
ALL JOINTS MUST BE TESTED AS THEY CAN LOOSEN IN TRANSIT.
The blending valve is set to maximum. See manufacturer’s leaflet if
adjustment is required.
The immersion heaters are rated at 3kW each, and should be set at 75
o
C
There is a thermal cut out on the thermostat. This may trip from time to
time and need to be re-set. Use only approved replacements.
The expansion vessel is charged at 3 bar and acts as a shock arrestor to
prevent water hammer and takes up expansion in the internal heat exchanger.
Thermal store units normally provide years of trouble free life, however they
should be serviced periodically. Advance recommends a service at least
every two years. It is important that the store temperature is maintained.
It is critical that the water level is checked if the unit doesn’t have the cold
service connected to the ballcock. About 50 mm depth in the cold section
is required. The transparent vent pipe acts as a sight glass to check water
level without removing the top. Simply open the valve on the flexible hose
to re-fill the unit.
Do not allow water levels to drop below the immersion heater as it will fail
if switched on in air.
Please note that if you are using one immersion heater only, it
must
be the
lower one otherwise performance will be compromised.
