Commissioning & Operation
.
DO NOT SWITCH ON THE HEATER UNTIL IT IS FILLED WITH WATER
Open the inlet control valve or tap to allow the tank to fill with water, the tank will be full
when water begins to run continuously from the spout or tap.
Close the inlet control valve or tap and switch on the electrical supply, adjusting the temperature
control to the required level.
The contents of the water vessel will be heated to the selected temperature.
NB.
During the heating cycle expansion will take place and water will drip from the spout
or tap. This will cease when the operating temperature has been reached, (approx 9
mins/+50°C for the 5L models, approx. 18 mins/+ 50°C for the 10L model).
Therefore always ensure that the spout outlet is positioned over the basin.
Hot water is drawn off by opening the inlet control valve or tap, this allows cold water to
enter the storage vessel as the heated water is displaced and is flowing out.
Safety Warning.
Under no circumstances is the water heater to be used if suspected of being frozen.
If water ceases to flow switch off the electrical supply immediately at the isolating switch.
It is then recommended that a qualified Plumber/Electrician checks the unit.
Any water can be drained via the cold inlet connection whilst in the original location.
To remove the outer case, prise off the temperature selector switch and release the screw
located beneath it.
Remove the four front cover securing screws at the top and bottom of the unit, the outer case
can now be lifted off.
Maintenance.
Very little maintenance is required, however it is recommended that the replacement of spare
parts is carried out by a relevant competent person ie. Plumber or Electrician for any more
