4.Using acetone, clean the oven floor where the new wave guide cover will sit.

5.Apply a 1/8” diameter bead of high temperature RTV (included with Item 29) along the outside edge of the wave guide cover flanges.

N O T E : It is important to use the correct high temperature RTV as supplied by TurboChef.

6.Place the new wave guide cover in place. Secure with the fourteen (14) screws provided with Item 29.

7.Wait 15 minutes for RTV to cure.

8.Warm oven to set temperature and re-check the tightness of screws. Tighten if necessary.

W A R N I N G : Inside of oven and IR element are HOT! Use extreme caution during step 8.

WAVE GUIDE REPLACEMENT

1. Remove the wave guide cover. See WAVE GUIDE

COVER REPLACEMENT on page 29.

2.Remove the right side panel and frame support (Item 32).

3.If replacing the front wave guide, use the NGC- 3016 kit. If replacing the rear wave guide, use the NGC-3017 kit.

4.Remove the two (2) right and left-most screws (Item 30) that secure the wave guide to the oven floor.

5.The wave guide should now be loose enough to easily slide out from the right side of the oven.

N O T E : Be careful to not damage the insulation when removing the wave guide.

6.Install the new wave guide using the mounting screws provided with the kit (Item 34 if rear wave guide, Item 37 if front).

C A U T I O N : Do not pinch insulation between the wave guide and oven bottom.

7.Reinstall the wave guide cover.

8.Reinstall the side panel and apply power to the oven.

HIGH VOLTAGE AND FILAMENT TRANSFORMER

REPLACEMENT

Wiring the High-Voltage Transformers

The proper reinstallation of the high-voltage and fil- ament transformers is critical. Upon removing a high-voltage transformer, make sure to note where each wire was installed. Refer to the oven schemat- ics (pages 55-63) detailing the proper wiring. Specifically, T1 and T2 are located in the top-right corner of the schematics.

As shown in the schematics, transformers are installed mirror opposite and wired 180º out-of- phase. It is essential for longevity that the high-volt- age transformers remain 180º out-of-phase. This can be checked by placing a volt meter across terminals T1-1and T2-1.

With the Microwave System energized, the volt meter will read the incoming voltage (different readings for

different countries). If the meter reads 0 VAC, the
