MAINTENANCE & OPERATION (continued)
Maintain Proper Water Flow
•It is important to operate and maintain the filter according to the manufacturer's specifications. As a filter gets dirty, the water flow to the heat pump is reduced. The higher the pressure on the filter gauge, the lower the flow rate.
•Similar to a dirty filter, large amounts of debris in the pump basket can reduce water flow. Keep basket free of debris.
•Check for improper valve settings. A partially closed valve after the filter, or a
•If the conditions listed above remain unresolved, the water flow through the heater may be reduced to a point where internal safety devices shut the heater off.
•Before calling for service, always check the filter, the pump basket, and water valve positions. If the problem persists, please call AquaCal Customer Support at:
Control Water Chemistry
•IMPORTANT! All AquaCal heat pumps are engineered for exceptional durability and reliability. And, this
•For the longevity of the entire pool/spa installation, and for the safety of bathers, it is strongly recommended the water chemistry be checked regularly and maintained within proper norms. Please see the table, below, for a complete listing of recommended water chemistry levels.

CAUTION- Pool/Spa Refinishing Operations
During pool refinishing or acid cleaning, the water flow through the heater must be shut off. Water flow to the heater must remain off until water chemistry is once again in balance and the water is clear in appearance. Failure to follow these instructions may void heater warranty.
