Seasonal USE & Shut Down, During the Swim Season

Maintaining 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. Apartially closed valve after the filter, or a full-open bypass around the heater, will cause insufficient water flow through the heater.

♦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, call AquaCal Customer Support at: (800) 786-7751.

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.

Maintaining Proper Clearances Around Heater

♦For maximum efficiency, proper air flow clearances around heater must be maintained.

♦It is important to keep the area immediately adjacent to the heat pump clear of items such as shrubs and bushes, lawn furniture, chemicals containers, etc. These items can prevent air from circulating fully through the heater, and will result in inefficient operation or damage to components inside the heat

pump. In addition, do not place objects on top of the heat pump; doing so will block the air from exiting the heater, and will result in damage to the compressor and fan motor.

♦Proper clearances are also necessary in order to access the working parts of your heater. A heater that is easy to "get to," will be a heater that is easy to maintain; service and maintenance personnel will thank you for keeping the area around your heater unobstructed.

♦Please see: Service, and Operational Clearances, located within the Installation section of this manual, for specific clearance requirements.

SEASONAL USE & SHUT DOWN

During the Swim Season

♦During the swim season, even if the pool or spa is not in use, allow water to flow through the heater. Doing so eliminates the need to reposition valves when you do wish to heat the pool or spa.

♦During periods where heating or cooling is not desired, leave POOL/OFF/SPAtoggle switch in the OFF position.

Freeze protection / Extended Shut Down

♦In areas where freezing conditions are a rare occurrence, allow the filtration system to run continuously through the freeze period. Typically, during light freeze conditions, circulating water will not freeze.

♦In areas where freezing conditions are prevalent, please refer to winterizing instructions following this section.
