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 ll 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 owing out.

Under no circumstances is the water heater to be used if suspected of being frozen.
If water ceases to ow switch off the electrical supply immediately at the isolating switch.
It is then recommended that a qualied Plumber/Electrician checks the unit.
Any water can be drained via the cold inlet connection whilst in the original location.
