Cleaning, Troubleshooting, Control Operation

Caution: External Surface Temperatures

The unit's external surface temperatures will be hot. Use caution when touching these areas to avoid injury.

Warning: Severe Burns - Ceramic Heaters

The white ceramic heaters operate at high temperatures. Do not touch elements after power is applied to the elements. Incorporated into the front surface of the element is a red color changing decal. As the element reaches a predetermined temperature, the decal will change from red to black. The decal will remain black until the element falls below the transition temperature where it will then return to its original red color. However, the element even if red will still be extremely hot. This color changing feature is used ONLY for determining if element is operating properly.

5.The deflector curtains located at the entrance and exit of the unit are used to contain the heat inside the unit, as well as keep any forced drafts from entering the unit. These curtains aid in efficient operation of the heaters and can be adjusted to increase or decrease the entrance and exit height. These curtains should be adjusted to the minimum height required above the conveyor for the product you are heating.

Control Operation

This oven has 2 heating zones, 1 on top, and one in the bottom. The top zone (Top Heat) is used to control all 5 ceramic emitters. The bottom zone (Bottom Heat) is used to control the bottom element.

6. CLEANING

Insure the appliance has been turned off and has had sufficient time for all surfaces to cool down before

cleaning. Use only mild soap and water to clean this appliance. Appliance cleaning should be performed daily.

NOTE: DO NOT USE ABRASIVE PADS OR CLEANING SOLUTIONS ON THIS APPLIANCE.

Daily Cleaning

Remove the crumb pans and wipe out debris with a damp rag and mild soap solution.

Remove the deflector panels located at the entrance and exit of the oven tunnel. Wipe down the area

under the deflector panels, and the deflector panels, with a damp rag and mild soap. Reinstall the

deflector panels by reversing the procedure used to remove them.

Using a damp rag with mild soap and water, wipe down the exterior surfaces of the appliance.

Using a damp rag with mild soap solution, wipe down all areas of the conveyor. DO NOT ATTEMPT TO

CLEAN THE UPPER WHITE CERAMIC, OR LOWER METAL HEATERS.

When units are in the stacked configuration, it is still necessary to clean between the units. Using a

damp rag with mild soap and water, wipe down the tops and undersides of all units. Ensure there are no

foreign objects between the units that could catch fire.

Using a damp rag with mild soap and water, wipe the surfaces of the stacking spacers on all four

corners.

7. TROUBLESHOOTING

Always ask and check the following:

Not getting power:

1.Is the unit connected to a live power source of the proper voltage?

2.Check the rating label. Is the unit connected to the correct power source?

3.Check the circuit breaker.

4.If the above checks out, and you still have problems, call your local service agent.
