REASSEMBLY POINTS
Because this is an outdoor product where the
control of water is important, the following steps
for assembly must be followed.
1. The closed cell foam gasket must seal the hex
shaped pan to the inside of the plastic housing
(see Figure 8). The seal is to be completely
even in the corners of joined parts.
2. The tubular heating element rubber sealing
washers must be against the top surface of the
steel pan and under the brass flat washers as
shown in Figure 9. Nuts on opposite side of pan
must be tightened 1/2 turn past finger tight.
3. Apply a SMALL drop of thread locking seal-
ant (rated to 300° F, such as Loctite Thread
Locker Blue) to each of the thermal reset
switch mounting screws (see Figure 10).
Torque screws to 6 to 9 inch-pounds.
4. The tip switch cover must isolate tip switch
from metal base as shown in Figure 11.
5. To complete grounding of heater, all ground
wires must be fixed with screws as originally
assembled by the manufacturer. Additionally,
internal tooth washers must be against the steel
pan and under nuts as shown in Figure 12, for
the tubular heating element.
6. No wires should be seen through openings in
bottom of heater (see Figure 13).
