7.1 Resetting High Limit Switch
Occasionally, the high temperature limit shut off device may
trip the reset. This occurs when water temperature exceeds
190 °F. The shut off device may also trigger from a power
outage or electrical storm.
To reach the thermostat:
▶ Disconnect power cord (or shut off circuit breaker - model
ES8) and remove the front cover.
▶ Firmly press reset button [B] with the tip of a ball point pen
or similar object.
Fig. 13
A click indicates the reset was tripped.
▶Reconnect power.
IMPORTANT: Check the operation of the thermostat:
▶ Turn temperature dial from high to low.
If the red light does not go off on low setting:
▶ Turn off power supply and call a service person to replace
the thermostat.
If the red light does go off the thermostat is working well:
▶ Place dial setting to desired setting.
▶ Replace cover plate.
A lower setting is more economical and
reduces the risk of scalding.
CAUTION:
Call a technician if the high limit needs to be
reset frequently.
