3.1.b Water Flow Rates
CAUTION
- Failure to heed the following may result in equipment damage.
Maintain water flow rates as shown below. Please note, these specifications relate to the heat pump only.
Code-specified whole system turnover rates must be satisfied. Contact AquaCal AutoPilot Technical
Support for guidance regarding testing for water flow rates.

Stop water flow when refinishing or acid washing pool. Failure to follow these
instructions may damage equipment and voids heat pump warranty.
To avoid damage to equipment, monitor and maintain chemistry within
recommended levels.
