The thermostat(s) on the immersion heater(s) should be adjusted to trip at

60°C. This is the ideal temperature to prolong element life in hard water

areas. Scale on the sheath builds up more rapidly at temperatures above

this causing the element to overheat and premature failure can occur. Higher

temperatures without additional controls would result in scalding.

In addition to the thermostat the thermal cut-out will switch power off to the

element should the thermostat malfunction, causing an excessive rise in

water temperature. The thermal cut-out can be reset manually after the fault

has been corrected.
