pools will typically lose only 3 - 4 ° of heat per night versus 8 - 10 ° overnight in an unblanketed pool.
Reductions of 40 - 60% on heating bills can be achieved by using solar blankets.

Seasonal Shut Downs

During the swim season, even if the pool or spa is not in use, allow water to flow through the unit. This
eliminates the possibility of chlorine gas from your chlorinator accumulating inside the heat exchanger.
Freeze Protection / Extended Shut Downs
In Florida or other areas where freezing conditions are a rare occurrence and winterizing of pools is not
common, allow the filtration system to run continually through the freeze period. Water circulating
through the heat pump will not freeze under typical conditions.
In areas where freezing conditions are prevalent the heat pump should be disconnected from the pool
plumbing. Electric power to the unit should also be shut off. The water contained in the heater should
then be flushed with fresh water to remove all traces of sanitizers, then drained thoroughly.
NOTE: FAILURE TO PROPERLY WINTERIZE THE UNIT MAY DAMAGE IT AND WILL VOID THE
UNIT'S WARRANTY.
For more detailed information on winterizing your unit or ordering a Winterizing Kit, please call AquaCal
at 800-786-7751.

Water Treatment

All Aqua Cal heat pumps are equipped with an internal bypass that allows only the proper amount of
water to flow through the heat exchanger. It is recommended that a non-corrosive check valve and a
Hartford loop be installed between any chlorinator and the heat pump. (See drawing below)
Chlorinators must be installed downstream of the heat pump. The proper sequence of installation is: pool
pump - filter - heat pump - chlorinator (or other feeder device). Locating a chlorinator in any other
manner may compromise the warranty of your heat pump. Adding chemicals such as sanitizers or pH
controllers through the skimmer of your pool should be avoided. Not only can they damage the heat
pump but other pool or spa equipment such as pumps and filters as well.
Suction type sanitizers that utilize the vacuum created in the pool pump strainer to pull chemicals into
the water are safe to use when installed in accordance with the manufacturer's instructions. The
chemicals injected into the pool water before the pool pump are well dispersed by the time they go
through the heat pump and will not cause harm when operated as per the manufacturer's instructions.
Skimmer feeding of sanitizers and pH adjusting chemicals should always be avoided.
The acceptable water chemistry levels are outlined below. If you have any questions concerning how to
check for these levels consult your installer for instructions. Pool and spa water should be checked at
least once a week and meet N.S.P.I. / ANSI Standard 5 Appendix A specifications. A few key levels are
outlined below. For additional information, contact the National Spa and Pool Institute (N.S.P.I.) at 2111
