Welcome Dear Owner: ongratulations on your wise decision to make an AquaCal heat pump part of your home. Since 1981, AquaCal has maintained the worldwide lead in the manufacture of swimming pool & spa heat pumps. Your new heat pump is not only a great investment, but also the most cost effective method available for heating pools and spas.
Important Features of Your The heart of your heat pump is the patented ThermoLink cause of premature heat pump demise is the failure of the heat exchanger. Ordinary heat exchangers are made from a cupronickel alloy. This cupronickel material is susceptible to attack from the sanitizers used in pools and spas, and from other related water chemistry conditions.
HOW A HEAT PUMP WORKS HE FOLLOWING EXPLANATION IS PROVIDED TO HELP YOU IN UNDERSTANDING … WHAT TO EXPECT FROM YOUR HEAT PUMP A Heat Pump Does Not Make Heat… Heat pumps are so extraordinarily efficient because they do not need to produce heat in order to warm pool or spa water.
Your installer can be one source of service, or AquaCal Customer Support personnel stand ready to assist you at: (800) 786-7751. For questions concerning installation, modifications, operation, service and upkeep, please contact your installer or AquaCal Customer Support.
Heat pumps contain no owner-repairable components. Repairs must not be attempted by untrained and/or unqualified individuals. If service is deemed necessary, contact installing dealer or AquaCal Customer Support at (800) 786-7751. Refrigerant Circuit Service Only by Qualified, EPA Certified Technician WARNING ! Heater contains refrigerant under pressure.

MAINTENANCE & OPERATION The time it takes to initially warm your pool or spa depends on several factors. First, determine how many gallons of water are to be heated. Knowing this, you can then compute the equivalent pounds of water involved, and the BTU's necessary to heat the volume of water to the desired temperature.
MAINTENANCE & OPERATION 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.
MAINTENANCE & OPERATION Winterizing Procedure: 1. Disconnect all electrical power to the heater; turn OFF circulating pump. 2. At the two (2) connection unions, disconnect the plumbing to the heater (removal is counter- clockwise). 3. Locate the hand drain plug at lower, front corner of heater. See Figure-3 (position may vary between models).
Just as you would have yearly service performed on your air-conditioning system, regular inspection and maintenance of your AquaCal heat pump will insure highest operating efficiencies. A regularly maintained heater will protect your investment, and will potentially extend the useful life of your heat pump far beyond the warranty period.
Is the air blowing out of the top of the unit noticeably cooler than the surrounding air? (A 9°F to 12°F difference is typical.) If not, contact AquaCal for service at: 800-786-7751. But first, be sure all air coil surfaces are free from obstructions– low roof overhangs, landscaping, walls, fences, etc., can restrict air flow.

- AquaCal anchoring kits satisfy, completely, the very stringent Florida Building Code Section 301.13: Wind Anchoring Requirements. -Contact AquaCal Parts Group (800-785-7751) to obtain the correct anchoring kit for the heater being installed. - Please have the heater model number ready when contacting AquaCal Parts Group.
Maximum Operating Pressure: 50-PSI Minimum - Maximum Water Flow Rates • All AquaCal 100, 120, and 155 models are designed to operate successfully at flow rates of 20- to-70 gallons-per-minute (GPM). • Design the plumbing system to maintain at least 20-GPM flow through the heater; the heat pump will not operate correctly, nor reliably, with less than 20-GPM of water flow supplied.

Always satisfy applicable codes and standards. • Multiple heaters installed at same site generally require special sequencing controls (an “ASC” controller will be required). If yours is a multi-heater installation, contact AquaCal Technical Support Group (800-786-7751) for application assistance.
Reference the Equipment Data Plate • AquaCal 100, 120, and 155 model heat pumps have two (2) identical data plates affixed: one can be found outside the unit, on right front corner; the second data plate is located behind the front access panel, on the electrical enclosure cover.
Generally speaking, the installer’s main focus within Level-2 programming will be in configuring for external controller compatibility. And, unless instructed to do otherwise by the AquaCal Technical Support Group, the installer should not adjust sensor calibration or dead-band values.

Then, if after working through site-related issues the heater is still not functioning correctly, the Service Representative will offer to set up a service visit. As necessary, please Contact AquaCal Customer Support Group (800- 786-7751).
Controls Configuration & Adjustments... Microprocessor Mode Jumper Positioning The HP7R microprocessor is designed to operate as a Heat-Only or a Heating & Cooling controller. The selection between the two choices is made through the positioning of a mode jumper contained on the microprocessor board.
Controls Configuration & Adjustments... Defrost Systems- Described DEFROST CYCLE (HEAT ONLY UNITS): The microprocessor controller monitors the heater’s air-coil temperature, minimizing air-coil freeze- up during cooler weather conditions. If the controller senses air-coil temperatures conductive to mak- ing ice, the heater’s compressor operation is interrupted while the fan is allowed to continue in opera- tion.
