1. Remove the fan grilles and PCB cover. The product is factory set at 15 minutes
approx. The overrun period can be adjusted from 3-25 minutes by altering the pot
on the control PCB.
2. To REDUCE the operating time, use a small screwdriver to turn the pot ANTI-
CLOCKWISE.
3. To INCREASE the operating time, use a small screwdriver to turn the pot
CLOCKWISE.
4. Replace the PCB cover, impeller and fan covers.
