Controller Location
Cable Lengths and Sizes

The controller should be out of reach of small
children.

Avoid locations where the controller may become
hot (near the oven or radiant heater).

Avoid locations in direct sunlight. The digital
display may be difficult to read in direct sunlight.

Avoid locations where the temperature controller
could be splashed with liquids.

Do not install in locations where it can be
adjusted by the public.
Models have their controller built into the front
panel. Additional controllers can be installed.
The cable for the temperature controller should be a
non-polarized two-core cable with a minimum gauge
of 22 AWG. The maximum cable length from each
controller to the water heater depends on the total
number of wired controllers connected to the water
heater.

temperature controllers with the power on. Although
the controller is a low voltage device, there is 120 volt
potential next to the temperature controller
connections inside the unit.
Do not connect the temperature controller to the
120VAC terminals provided for the optional solenoid
drain valves.
