WIRING THE CONTROL
SET UP AND RUNNING INSTRUCTIONS
1. Install the control in a well ventilated area where the ambient temperature
does not exceed 40°C.
2. Ensure the control is securely mounted.
3. Route cables through the knock out holes at the bottom of the unit and
ensure electrical connections are correct.
4. Switch on the mains supply. Switch on the speed controller.
5. Rotate the control knob from an anti-clockwise position to a clockwise
position and check the fan accelerates to fill speed.
6. Minimum Speed - The minimum speed is preset and does not normally
need adjusting. If this is necessary firstly ensure the control knob is set to
minimum (filly anti-clockwise) then open the lid to access the
potentiometer (MIN). Adjust as required. Beware of setting too low a value
which could cause a stall condition on the fan.
