START-UP

1. For heaters with a tamper-proof thermostat, to set
temperature, disconnect the power and remove the socket
head cap screw. Set the thermostat to the desired room
temperature with a screw driver and replace cap screw.
2. For heaters with an externally adjustable thermostat, set
thermostat to desired temperature by adjusting the dial.
NOTE: The thermostat temperature range is 0ºF – 100ºF
(-18 ºC– 40ºC) with an operating differential of 5ºF – 7ºF
(3 ºC– 4ºC).
NOTE: High ambient thermostat temperature range is 0ºF–158ºF
(-18ºC–70ºC) with an operating differential of 5ºF – 7ºF
(3 ºC– 4ºC).
3. Install the terminal box cover and tighten securely.
4. Check to ensure that all plugs, screws, and covers are
securely in place.

MAINTENANCE

1. Periodically inspect the heater installation to ensure that all
connections, fittings, plugs, screws, covers, etc. are tight
and free of corrosion.
2. Check that the reflector baffles (if required) have not moved
upwards or downwards in relation to the heat sink.
3. Check the extrusions of the heater for dust and debris.
A blast of compressed air is recommended for cleaning
the heat sink. If air is not available, disconnect the power
supply to the heater and when cool, wipe it down with
a damp cloth or soft brush. Remove wire guards prior
to cleaning.
WARNING. Disconnect power from the heater before
performing any maintenance. Failure to do so can result
in property damage, injury, or death.
WARNING
CAUTION. Do not use water to clean heater.

models.
4. The heat sink is anodized or painted black to ensure that
the maximum area code temperature is not exceeded.
After an extended period of use or in extremely harsh
environments the anodization/paint may wear away
leaving bare surfaces. For continued safe operation, these
surfaces must be repainted. When repainting use only
black high temperature resistant paint.
5. Except for thermostat replacement, field repair of the
heater shall not be normally undertaken. In the event that
the heater must be repaired, contact the factory for a
return authorization number.
