MAINTENANCE
7.1 Cleaning: Clean the oven interior and remove and clean shelves on a regular
basis. Use a disinfectant that is suitable for your application. DO NOT USE
chlorine-based bleaches or abrasives, as this will damage the stainless steel
interior. DO NOT USE spray cleaners that might leak through openings and cracks
and get on electrical parts or that may contain solvents that will harm the coatings. A
similar periodic cleaning is recommended. Use care when cleaning the door gasket
to prevent damage which could impair the positive door seal.
WARNING: Never clean the unit with alcohol or flammable cleaners with the unit
connected to the electrical supply. Always disconnect the unit form the electrical
service when cleaning and assure all volatile or flammable cleaners are
evaporated and dry before reattaching the unit to the power supply.
7.2 Storage: To prepare the unit for storage, remove all shelves and shelf clips, dry
the chamber completely and disconnect the power supply. Be certain that the
door is positively locked in the closed position. See Section 3.3, Lifting/Handling,
for proper transport procedures.
7.3 No maintenance is required on the electrical components. If the unit fails to
operate as specified, please see the Troubleshooting guide, Section 8.0, before
calling for service.
7.4 Preventative Maintenance Recommendations:
• Clean the oven interior and shelves whenever they get stained or dirty.
• Inspect the door gasket, making sure it is in good condition, and that the
door seals snugly against its mullion.
• Level the oven, using its adjustable feet.
•
If you suspect that air flow across the work space has decreased, have the
blower wheel cleaned. It is possible for the blower to get dirty if the oven is
used with dirty, lint-laden loads.
• Test the Overtemp Thermotstat (OTP). Run the oven at some usual
temperature. Stabilize. Turn the OTP safety thermostat to a temperature
lower than that on the main temperature controller. Make sure the OTP light
comes on, and that oven temperature decreases.
