FURNACE MAY BE INOPERABLE DUE TO DAMAGE TO THE INSULATION. Contact the
manufacturer if cleaning is required.
3.2 Service and Maintenance Access
Observe extreme caution when the furnace power is engaged while the access panels are
removed. Dangerous levels of AC and DC voltages will be present.
LOWER PANELS.
Gain access to the lower sections of the furnace by turning the quick release screws and
removing the panels. For convenience, lower panels can be hung from the slots in the upper panels during
service.
Make sure the EPO switches on lower electrical panels are pulled out if the furnace is to be energized while
these lower panels are off.
When the panel that houses the 3-Phase Disconnect Switch is removed, turn the switch to off to disengage
the switch and allow removal of the panel. Hang the lower panel from upper panel.
UPPER PANELS. Once the lower panels have been removed. The upper panels can be lifted and
removed. When replacing the upper panels carefully lower the top of the panel into the slot provided and

3.3 Daily Maintenance
Daily maintenance consists of a simple series of functional checks that will alert maintenance personnel to
any signs of developing problems. The importance of regularly checking the machine cannot be over
stressed to prevent not only damage to the machine, but also loss of productive time and product. Whenever
the furnace is started up the failure alarms should be checked for signs of trouble. An intermittent exhaust
failure indicates that something is wrong and that the alarm mechanism, system exhaust fan, and possibly
exhaust ductwork must be checked and corrected as necessary. Other alarm functions should be monitored,
such as the lamp failure indicator, to see if corrective action is required. As the machine is being started,
each control and switch should be briefly checked to ensure that all functions are working properly. Any
controls that do not respond as expected, or alarms that do not clear should be checked out and corrected
before putting the machine into operation.
