3.0 General
Warning: Hot surfaces are present during and after operation. Areas are marked by appropriate labels
as noted above. Do not touch them or serious burns may result.
Caution: The preheater will heat up to and maintain the set temperature as long as the power switch is
in the on position.
Warning: Electrical shock hazards exist inside the Preheater. Access this area only by an experienced
technician and only after removing power and air connections.
Keep the equipment clean of debris and flux deposits with appropriate cleaners. Do not allow liquid to
flow into the interior of the electrical enclosure thru and of the openings.
Do not scrub the heater plate with any abrasive material or device. Damage to the surface can result.
Clean the bearing rails and oil with a light machine oil as required to prevent sticking of the rail movement
and rusting of the rails.
