Maintenance Instructions
1.
Introduction
Proper maintenance contributes not only to the service life and efficiency of the oven but also to a safe workplace. In addition to performing as-needed repairs to the oven, it is important that qualified personnel perform scheduled maintenance. Qualified personnel include hired contractors and trained maintenance personnel.

Scheduled Maintenance
The recommended scheduled maintenance has been broken down into weekly, monthly, semiannual and periodic needs. Outside of the daily checklist addressed in the operation instructions, there is no daily recommended scheduled maintenance for the oven. Operators are instructed to notify their managers if any maintenance concerns arise during daily operation.
2.1 Weekly Checklist
The following items require regular weekly maintenance:
2.1.1 Weekly Maintenance for Gas and Electric Ovens
1. Inspect belts for fatigue and proper tension. Replace fatigued belts. Adjust belts if they are squealing or touching the belt guard.
2. Inspect thermocouples and lead wires for shorts or loose connections. Repair or replace as necessary.
3. Check setting and operation of temperature control. Program, adjust or replace as necessary.
4.
Test alarms for proper signal. Repair or replace as necessary.
2.1.2 Additional Weekly Maintenance Required for Gas Type Ovens
In addition to the items above, gas heated ovens require attention to the following items on a weekly basis:
1. Inspect burners for proper flame (see the Eclipse flow diagram). Adjust for proper high fire setting as necessary. 2. Check gas pressure switches for proper settings. The oven, as originally manufactured, was set up for a 5 PSI supply pressure.
3. Inspect all motor valves and control valves for free smooth action. Adjust or replace as necessary.
