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)
