Safety
The Model 4555 Heater is designed for safe operation. Nevertheless, installation,
maintenance, and operation of the heater can be dangerous for a careless operator or
maintenance person. For your safety and the safety of others, read the instructions in this
manual and follow these warnings to help prevent accident or injury.
Due to high voltages present in typical Model 4555 installations there is danger of
electrical shock when installing, operation, or servicing the heater. Exercise extreme
caution when handling or working with these high voltages.
All applicable local and national electrical codes should be followed to ensure proper
installation and operation of the Model 4555. A safe electrical ground must also be
provided and properly installed on the heater before attempting to operate the unit.
WARNING!
Power lines and any other affiliated heater circuitry (i.e., blowers, thermostat, etc.)
must be disconnected prior to any servicing issue including lamp installation and
change out.
The Model 4555 heater should never be operated with the end covers of the heater
removed.
The presence of open load-to-ground must be verified after lamp installation into the
Model 4555 and before system power is applied.
Certain areas of the Model 4555 heater may exceed 500° F (260° C) while the heater is in
operation. Exercise extreme care when working in close proximity to an operating heater.
WARNING!
NEVER place any part of the body under or near any part of the heater while power is
applied.
Always allow the heater to cool sufficiently (at least 5 minutes with the blower operating,
longer if the blower is not operating) before servicing any part of the heater, including
lamps or adjacent parts.
CAUTION! Continuous exposure to high-intensity infrared radiation at close
proximity could be harmful to eyes or skin. Although infrared lamps emit negligible ultra
violet electromagnetic radiation, harmful burns can still result if an operator is in close
contact with lamps being operated at high intensity.
Because of the brilliant light emitted by infrared lamps at full intensity, it is recommended
that eyes be shielded from the glare if observing the lamps for an extended period of time.
Use suitable shaded lenses or dark glasses.
