4.2 REPLACING THE CATALYTIC CARTRIDGE

1. Turn off power to the converter and allow to cool. IT IS VERY IMPORTANT

THAT THE CONVERTER BE COOL BEFORE ATTEMPTING ANY

DISASSEMBLY OR REPAIRS.

CAUTION VERY HOT

Will cause severe burns – disassembly while hot will

damage other converter components. Allow sufficient

time to cool.

2. Remove the chassis cover of the M501 NH

, remove the aluminum cover over

the oven, remove the two U-shaped hold down clamps.

3. Disconnect the 1) stainless steel and 2) PTFE tubes from the converter

cartridge.

4. Loosen the nut holding the cartridge assembly in the U-shaped angle bracket

mounted on the chassis floor.

5. Gently lift and tilt the converter assembly out of the U-shaped bracket and

slide the assembly out of the oven.

6. Loosen the ¼” SS tube fitting nearest the hold-down bracket; this fitting holds

the central tube in the converter. Replace the tube that is part of KIT000193.

7. Re-assemble the converter by doing the above steps in reverse order.
