DUAL CIRCUIT INDICATOR:
The amp draw of the two circuits of the E-TES SD 120 Volt unit requires that the two power cords be plugged into
separate outlets. To assist you in determining if the cords are plugged into separate circuits, The E-TES SD 120
Volt unit is now equipped with a dual circuit indicator.
With both power cords plugged into outlets, connected to the E-TES SD 120 Volt unit and the GFCI’s reset, turn
E-TES SD unit power switch to the ON position. Observe Dual Circuit indicator light next to rocker switch. If
green light is ON, cords are on separate circuits and you can proceed with set-up. If light is OFF both cords are on
the same circuit and one cord must be moved, one cord is not supplying power. Display will light, Power & Heating
lights may turn ON if Cord #1 has power even if Cord #2 is disconnected. Both cords must be connected and
Dual circuit indicator light must be ON for proper heater operation.
When cords are on separate circuits and green Dual Circuit indicator light is on proceed with set-up.
Improper wiring of electrical outlets can prevent the indicator light from turning on. Using an overloaded circuit
may cause the circuit breaker to blow even if both cords are on separate circuits.
An AC128 SureTest Circuit Analyzer can be used to test the outlet wiring and existing load to reduce the chances of
the circuit breakers tripping during E-TES SD operation.

With Cord #2 disconnected or connected to a dead outlet, as
long as there is power to Cord #1 and Cord #1 is connected to
the E-TES SD 120 Volt unit, the LED display and the POWER
& HEATING indicator lights will still function, but the heater
will only operate at one half of its rated heating capacity.
