Front Entrance Box Modification

1. Inspect the front entrance box to see if it has the hole pattern required to install the new high temperature
limit. Proceed to the following steps only if the front entrance box does
NOT include the hole pattern shown. (See Diagram C)

2. Drill two 7/32” holes and one 5/16” hole in the front entrance box in the
outlined locations. (See Diagram D) Diagram D is shown actual size

and therefore can be used as a template for locating hole centers.

3. Remove all burrs and sharp edges from the drilled h oles. Remove any
metal shavings created from the drilling operation.

High Temperature Limit Subassembly

1. Attach high temperature limit wiring to the
new high temperature limit.
(See Diagram E)

2. Fold over the flaps on the high temperature
limit to cover the wiring connections.
(See Diagram E)

3. Attach the high temperature limit to the
bracket using two 6-32 screws.
(See Diagram E)

Installation

1. Apply silicone sealant to the reducer
bushing. Install the bushing into the hi-limit
coupling. (See Diagram F)

C) Bracket D) 6-32 Screws

Diagram E

2. Insert the high temperature Limit bulb into the tank through the hi-limit coupling. (See Diagram F)

3. Secure the bulb to the heating element using two bulb clamps, 10-24 screws and wing nuts. The clamp
should be located 2 to 3 inches from the front of the tank. (See Diagram F)

4. Insert the Teflon seal into the reducer bushing. (See Diagram F)

5. Apply silicone sealant to the high temperature limit bulkhead fitting and install the fitting into the reducer
bushing. (See Diagram F)

6. Adjust how much of the capillary is inside the tank until it travels a short, smooth and kink free path inside the
tank. Assure that the capillary does NOT come in contact with the element at any point.

7. Tighten the compression screw on the bulkhead fitting until the capillary is secure. (See Diagram F)

8. Fill the cook tank with water and inspect the tank coupling
connections to assure that they are leak free.

9. Drain the water from the tank before p ro cee ding.

10. Attach the high temperature limit subassembly to the front entrance
box using two 10-24 self tapping screws. (See Diagram G)

11. Connect the DVI jumper to the connector with orange and violet/white
wires on the new front entrance box wiring. (See Diagram H)

12. Connect the new front entrance box wiring to the components in the
