Notes:
The 2 external contactors must be approved components certified for 10,000 cycles of operation for
the contactor controlled by the thermostat and at least 30 for the contactor controlled by the
none self-resetting thermal cut-out.
Thermostat/Cut-out
All auxillary immersion heaters are fitted with a thermostat which is fitted in the centre of the
heater plate and a cut-out which is fitted to the side of the thermostat. These MUST be wired
in series with the operating coil circuit of the contactor (not supplied). See figures 4 below and
figures 5 & 6.
Maximum working temperature is 80°C/176°F. In very hard water areas limit to 60/65°C
(140/150°F)
For optimal working conditions the thermal cut-out should be set to 80°C (factory set, if the seal
is broken it may invalidate your warranty) and the thermostat should be set to 70°C max. If the
thermostat is set above 70°C there could be instances nuisance tripping of the thermal cut-out.
