You will find the pump switch behind the pump on the side opposite the electrical wire.
Here are the programming options based on the two-speed programmable pump setting:
* Level 1 (single tone): Pump runs at high speed for 24 hours.
* Level 2 (2 tones): Pump runs on high speed for 18 hours, on low speed for 6 hours.
* Level 3 (3 tones): Pump runs on high speed for 12 hours, on low speed for 12 hours.
* Level 4 (4 tones): Pump runs on high speed for 6 hours, on low speed for 18 hours.
During the peak swimming season, we recommend programming at the pump to level 1 or 2.
