3.1 USE THE APPLIANCE FOR THE FIRST TIME
Before switching the appliance on please familiarise your-
self on how to isolate the appliance from the electricity, gas
and water supplies. If in doubt contact your installer.
3.2 USE THE MODE SELECTOR SWITCH
Turn the mode selector switch to the OFF position, switch on
the electrical supply to the appliance. The green LED should
be flashing, you may now switch the boiler selector switch
to the ON position.
3.3 RE-PRESSURING THE SYSTEM
The system will need re-pressurising if the red LED is
illuminated and the pressure gauge is reading below 0.4bar.
Locate the filling valve and if necessary connect the loop (fig.
2) slowly open the valve until you hear the water entering the
appliance. The red LED will go out first. Go on with re-
pressuring until the pressure shown on the manometer is
between 1 & 1.5 bar (fig. 3). The appliance must not be
operated until the system has been re-pressurised. If in
doubt contact your installer.
3.4 SHUT DOWN THE SYSTEM FOR SHORT PERIODS
The system can be shut down for short periods by simply
turning the mode selector to the OFF position. It is also
advisable to turn off the main water supply to the house.
3.5 SHUT DOWN THE SYSTEM FOR LONG PERIODS
If the house is to be left unoccupied for any length of time -
especially during the winter - the system should be thor-
oughly drained of all water. The gas should be turned off at
the meter and the main water supply should be turned off at
the stopcock. If necessary contact your installer for further
advice.
3.6 CARE FOR THE APPLIANCE
To clean the outer casing use only a clean damp cloth. Do not
use any scourers or abrasive cleaners.
