The unit has superior field strength due to the relatively high amperage that it draws. The consequence is fairly rapid heating of the field coil. It is recommended that a single duty cycle be limited to 5 seconds on and 3 minutes off, or three 5 seconds cycles on and 10 minutes off. This unit is wired with a thermal protector. If the above duty cycles are not observed, the thermostat may open and the unit will not operate until it has cooled sufficiently. Features a 1 1/2" X 3" opening.
