Fry Warmer Installation

Below is a list of tools and material that will be used during installation:

• DOW CORNING RTV sealant 732

• Handheld Drill (12 VDC)

• 9/64” drill bit (for metal)

High Voltage. Remove power from the KFC® K46HS Heated Storage Table. This unit may
have more than one disconnect switch. Failure to do this will result in death or serious
injury.

1. DISCONNECT POWER TO THE TABLE.

2. Remove screws holding control panel into place. Carefully pull the control panel away from the unit to
obtain access to the wiring.

3. Depending on whether the Right Side well or the Left Side well is to be disabled, remove the power wires
from the back of the power switch for that well. This would be wires #1 and #2 for the Left Side or wires
#5 and #6 for the Right Side. Using the male connectors provided (F0243), cap these wires individually
creating a dead end on each wire.

4. Replace control panel into unit and install screws.

5. Restore power to the table.

6. Remove the strainer from the drain in which the KFW will be mounted.
