EMI Kit Installation
Turn off and disconnect all power prior to beginning installation. Failure
to do so could result in serious injury or death.
1. Turn off the oven and disconnect the power at its source. Remove the side
panel from the Combo Oven. Carefully note the wire markings (labels) on the
machine-side leads (extending into the machine from the terminal block) at the
main power terminal block and their connections. Disconnect these machine-
side leads from the terminal block. Put the leads through the middle of the
large toroid and wrap them once around its outside. Then pass them through
the middle of the toroid. Reconnect the leads to the terminal block.
Note: Some wiring harness tie wraps must be cut to be able to get the wires
through the toroid. Tie wraps may also be used to hold the harness tightly
together to pass through the toroid a second time. Such wraps are seen in the
picture of the CC10-E example at the right.
2. Install a Surge Suppressor Board for the type of Combo Oven.
Note: If your unit is already equipped with a surge suppressor board, skip to
Paragraph 3.
Part No. 098410 - for gas ovens – The board is screwed in to the space
provided on the right of the power block.
Part No. 098703
- 208/240 Volt electric ovens.
Part No. 098707
- 480 Volt electric ovens.
On electric ovens, the board mounts behind the power block, and in the same
holes.
3. Remove the boiler and air probe connectors from the Control Panel. Pass the
leads through the middle of the small toroid, wrap them once around the
outside, and pass them though the middle of the toroid again. Reconnect the
probes to the Control Panel.
4. Install the shorting jumpers to the four unused inputs on the Control Panel.
These four inputs are located near the air and boiler probe connectors.
