Safety
The Model 5420 Power Controller 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.
There is a danger of electrical shock when servicing this power controller or the attached
heating unit. Always disconnect the power cord when servicing the power controller or
the heating unit. Never operate the 5420 power controller with the cover removed or with
the heating unit cover removed. The covers have been design to protect the operator
from the high voltage present inside the unit.
WARNING!
Always disconnect the power cord when servicing the power controller or the
connected heater.
WARNING!
NEVER operate the power controller with the cover removed or the heater cover
removed.
The heating unit connected to the 5420 also requires special safety precautions. Parts of
the various heating units may exceed 500°F (260°C). Contact with the lamps, reflector, or
metal parts near the lamps can cause severe burns.
INFRARED RADIATION - 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.
