Tudor - Installation & Operating Instructions - 85807 - June 2012 v1.00

 Operating 

Procedures

Water Temperature

Tudor water heaters are fully automatic, and may be left switched ON under 
the control of the variable thermostat. 

Nominal operating temperature can be varied from about 30°C to about 80°C.

Temperature should not be set to less than 60°C without due regard to 
regulations governing the storage temperature of hot water. 

Economy Setting

The economy setting “E” will maintain stored water temperature at 
approximately 60°C. At the “E” setting, the temperature control locates into a 
set position and a slight resistance will be felt when rotating the temperature 
control beyond that setting. This measure is to help ensure that higher 
temperatures are only selected deliberately.

Frost Protection

If the heater is located where ambient air temperature could fall below 5°C 
when the heater is not in use, the “anti freeze” setting on the temperature 
control will maintain stored water temperature over 5°C to prevent freezing 
and damage to the water heater.

The same protection does not extend to connecting pipework or fittings. 

Safety Cutout

Should the heater over-heat, a manually resettable safety cutout will 
automatically turn the heating element OFF. The cutout must be reset by a 
Service Provider or a licensed electrician. Users should never reset the cutout 
without qualified assistance.

Cleaning

Never use strong, corrosive or abrasive cleaning materials. Wipe clean the 
outer surfaces with a sponge or soft cloth using a mild soap and water. 
Domestic dish washing liquid detergent is most suitable.
