INSTALLATION

THERMO-SENSORS

1. Using duct tape, attach the Over Limit thermo-sensor (marked with red) to the central area of

the upper-most heating element. Locate the sensor approximately 1-1/2 ft/450 mm from the

cord end of the heating element.

2. Using duct tape, attach the Maintenance thermo-sensor directly to the tank wall approximately

6 inches/150 mm from the bottom-most heating element.

CONTROL UNIT — ON TANK WALL

If the control unit is located on the tank itself, finish tightening the

strap so that the box is secured in place.

CONTROL UNIT — REMOTE LOCATION

If the control unit is located remotely from the tank, attach the con-

trol unit, using standard electrical practices, to any suitable surface,

pole, etc.

Note

Make sure that the strap does not cross any heating elements, power cords or thermo-

sensor leads.

Note

Standard lead lengths on the thermo-sensors and heating elements are 20 ft/6 m and

8 ft/2.5 m respectively. When locating the control unit, ensure that the thermo-sensor

wires and heating element power cords are not stretched taut and do not cross over

the heating elements.
