Original Instructions (English)
WARNING
– Risk of Electric Shock
If thermostats are supplied with the heater, they are for pilot duty use only. Consult
specific product wiring diagram supplied with the heater for the allowable wiring of
thermostats.
Thermostats should not be relied upon to remove electrical power for maintenance.
The use of a disconnect switch or circuit breaker is highly recommended and will
allow the isolation of the heater when maintenance is required
.
WARNING
– Risk of Electric Shock
The Mains / Line voltage applied to the heater must always be equal to or less than
the voltage ra
ting marked on the heater’s nameplate.
Some heaters are supplied as dual voltage (e.g. 240V / 480V) units and hence the
User needs to check the wiring diagram supplied with the heater to ensure that the
heater is wired correctly for their supply voltage. In most cases (unless specified by
User) the heater as received will be wired for the higher operating voltage.
