High Temperature Limit Removal
1. Ensure that the power is disconnected and that the
tank is drained.
2. Remove the two screws securing the bezel to the front
of the appliance. Keep the two screws in a safe place
since they will be required later. (See Diagram A)
3. Tilt the bezel down and disconnect the wire plug
connected to the controller. (See Diagram A)
4. Remove the Bezel from the appliance. Keep the bezel
in a safe place for reinstallation later.
5. Disconnect the wire harness from the high
temperature limit, temperature probe and circuit breaker. (See Diagram B)
6. Disconnect the remaining connection on the wire harness and remove the harness from the appliance.
7. Remove the high temperature limit from the appliance. (See Diagram B)
WARNING
The power supply must be disconnected
before servicing this appliance.
WARNING
Drain the appliance before performing
the following procedure.

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 holes. 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)
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)

on the bezel.
14. Reinstall the bezel and secure using the
two screws removed during disassembly.
15. Replace the schematic label located
inside the door with the new schematic
label.
16. Startup the appliance per the procedure
shown in its installation and operation
manual. Assure that the appliance is
operating properly.
