8. Operation

8.1 General

  The appliance stores water at the temperature set 

on the internal adjustable thermostat. This can be 

set to give temperatures in the range 10°C to 70°C. 

The factory set temperature is set at 54°C.

  The temperature control is underneath the cover, 

please see figure 9, page 15 on how to remove.

  Turn the adjustment knob clockwise to set hotter, 

or counterclockwise to set cooler.

  In hard water areas it is advised that the maximum 

temperature is restricted to prevent build up of 

scale. 

  To avoid risk of freezing when the heater is not 

in use for long periods during the winter months, 

do not switch off the electrical supply and set the 

thermostat to its minimum position. N.B. This will 

not protect other system pipework.

  The indicator light will be illuminated when the 

appliance is heating.

  To ensure the appliance continues to operate at 

its optimum performance it should be periodically 

maintained in accordance with the instructions 

given under the section headed MAINTENANCE.

WARNING

  DO NOT bypass the thermal cut-out in 

any circumstances.
