current consuming appliances in the property (such as tumble dryer,
showers, cookers etc). A large domestic pool pump of 1 horsepower will
draw less than 1kW in a one hour period. The conclusion of the test should
prove that for example a 6kW heater and a ½ horsepower pump will draw
between 6.3-kW ~ 6.5-kW in one hour. It is impossible for an electric heater
to waste energy, if it is drawing power then that power will be turned into
heat that will be transferred to the water.
Trouble Shooting
HEATER WILL NOT SWITCH FROM STANDBY (AMBER LIGHT ) TO ON
(RED LIGHT)
In most cases this will be the result of one of the following points not
being met.
Possible cause 1: The set point temperature has been achieved. To confirm
increase the set point value by turning the temperature set point dial to a value
greater than the current water temperature.
Possible cause 2: The 'thermal safety cut out' has tripped.
Remedy: Remove button cover and press red button to re-set (see fig 7)
If a positive click is felt, the cause of the tripping must be investigated and
could be caused by a debris build-up or air pocket trapped inside the flow
tube of the heater.
