9.) PREVENTIVE MAINTENANCE
CAUTION:
Maintenance should only be performed by trained personnel.
WARNING:
Prior to performing maintenance to the oven or the controls,
the main power must be disconnected. Prior to maintaining this
equipment, read the applicable MSDS at the back of the manual.
General Oven Maintenance
LIGHT
1.
Inspect and verify all electrical connections for tightness. Due to thermal
expansion during the heat- up/cool-down cycles electrical connection may
become loosened.
2.
Inspect the heating elements. Do not allow build up of foreign material on
the element. Oil should be cleaned off of any part of the oven prior to
heating. Use caution not to displace the heating elements as the wire may
be brittle and break easily.
3.
If oven has a door, verify that the door safety switch is operating and
cutting the power to the heaters once the door is opened.
4.
Check all hardware fasteners to ensure that they are tight.
5.
Inspect the tip of the thermocouple for excessive heat deterioration.
General Control Cabinet Maintenance
1. Verify that all electrical connections are tight.
2. If applicable, clean the cabinet cooling fan filter.
3. Check all cabinet to oven interconnection wiring.
4. If applicable, check to ensure that all signal lamps light.
REPLACEMENT PARTS
It
is recommended that you obtain replacement parts from Thermcraft Inc. to insure that
system safeguards are not compromised. Variations in component specifications could
cause the equipment to be unsafe.
ELEMENTS HEATING
The elements should last more than three (3) years unless overheated due to restricted
air flow or a malfunction of the control system. No other maintenance is required.
