Big Dipper Internal Strainer (IS) Models
The Big Dipper W-750-IS model is equipped with one (1) Push Button Digital
Time Controller while the W-1250-IS model is equipped with two (2) Push
Button Digital Time Controllers. The push button control is located under the
hinged lid of the motor enclosure on top of the lid of Big Dipper (See Digital
Timer Operation Instructions). The Big Dipper should only be plugged
into a properly grounded 3-prong 120 VAC or 230 VAC outlet. If pos-
sible, the power supply outlet for the Big Dipper should be connected to an
electrical circuit controlled by a ground fault circuit breaker.
One of the setting buttons should be illuminated to show the unit is pow-
ered. If none of the setting buttons are illuminated, the unit is not powered.
This Big Dipper unit is shipped from the Factory wired for Simultaneous
Operation. This means the Heater and Motor operate at the same time
under digital control. Continuous Heater Operation is where the Heater is
active at all times. To switch to alternative heating programming, please
contact a Thermaco representative for furher instructions.
Note: The Big Dipper unit will not operate when the lid is removed.
