SuperQuiet likely your heat pump will be quieter than any other item on the pool equipment pad. The cabinet, being made from resilient, UV-Protected ABS material, has superior fade resistance and can never rust or corrode. -
Page 7: How A Heat Pump Works
If one considers Absolute Zero (the point where all heat is absent) occurs at -459º Fahrenheit, it becomes evident outside air, even at the relative cool temperature of 55º Fahrenheit, still contains large amounts of heat energy. It is that abundant heat energy a heat pump captures and places into your pool or spa. -
Page 8: Safety Information
Likewise, excepting a few minor owner-capable maintenance items (explained later in this manual), repair and service of your heat pump must be performed only by experi- enced service personnel. Should you, the owner, suspect your heat pump is not per- forming properly, by referring to the section in this manual entitled: "Troubleshooting,"... - Page 9 Pool/Spa water per standards detailed later in this manual. CAUTION ! While your heat pump’s titanium-based heat exchanger provides nearly impervious protection against poor water chemistry, improper water chemistry may cause expensive damage to pump, filter, pool shell, etc. To avoid equipment damage, maintain Pool/Spa water per standards detailed later in this manual.

D. Use the UP / DOWN arrow keys to set the desired water temperature for the POOL water. E. If the heat pump will be used to heat a spa, use the POOL/SPA selector key to select SPA, then use the UP / DOWN arrow keys to set the desired water temperature for the SPA. An illuminated SPA indicator light, located on the left side of the display, will confirm the SPA control has been selected. - Page 11 Colder months require longer running times - generally eight to twelve hours/day. C. A heat pump can only operate when the filter pump is running. Therefore, it may be necessary–during cooler weather–to extend the water pump’s hours of daily operation.

Planned Maintenance Program, rinsing the air coil regularly, and keeping the base of the unit clear of leaves and debris is a necessity. Should you as the owner desire to perform the coil rinsing and other cosmetic care of the heat pump, please contact AquaCal Customer Support: 1-727-823-5642; request the document titled: “Appearance Care for Air-Source Heat Pumps: Approved Method for Home Owners.”... -
Page 19: 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. -

Page 21: Heating Tips
A “solar” blanket will significantly reduce your heating bills. Check with the installing dealer to see if your heat pump was sized to be used in conjunction with a blanket. Blanketed pools will typically lose only 3 - 4° of heat per night versus 8 - 10° overnight with an un-blanketed pool. Reductions of 40-60% on heating bills can be achieved by using blankets. -
Page 22: Calculating Initial Heating Time
At Start Up: Continuous Circulation Pump Operation Required When starting a heat pump for the first time, it must be permitted to operate, continuously, until the desired water temperature is attained. This may take several hours, to several days, depending upon the size of the pool or spa and weather conditions. -
Page 23: Seasonal Use & Shut Down
Typically, during light freeze conditions, circulating (moving) water will not freeze. In areas where freezing conditions are prevalent and sustained, the heat pump MUST be winter- ized; please refer to winterizing instructions, below, and on the following pages. -
Page 24: Winterizing Procedure
If so, remove plug, and allow water to drain out of the condensor. PLEASE NOTE - If your heat pump contains an exchanger other than what is shown above, call AquaCal AutoPilot for alternate winterizing instructions. -
Page 25: Aquacal Preventive Maintenance Program
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. -
Page 26: Troubleshooting (No Op, No Heat, Water From Unit)
If so, check to be sure that the circulating pump is operating and the filter is clean. There may also be a valve positioned incorrectly allowing water to bypass the heat pump. Be sure water is flowing through the heater. -

Refer to required clearance drawings below. • Allow five (5) feet of vertical clearance between the top of the heat pump and any roof overhang or other obstruction. This clearance prevents cold discharge air from recirculating back into the heat pump (recirculation will reduce the overall performance of the heat pump). -
Page 40: Irrigation, Rain Runoff, And Landscape Factors
Irrigation, Rainwater Runoff, and Landscape Features • Place the heat pump away from direct rain runoff from roofs. If roof slope directs runoff into the heater, a gutter or rain shield will be required on the roof edge above the heat pump. -

Water flow exceeding 70-GPM may damage titanium condenser; such damage will NOT be covered under the equipment warranty. Install a bypass check valve (AquaCal P.N.: 2556, or equal to Del Industries P.N.: CO-0103) whenever water flow rate may exceed 70-GPM. Contact AquaCal Technical Support (727-823-5642) for guidance regarding testing for water flow rate. - Page 43 Plumbing Requirements General Plumbing Schematics – Flow 30 to 70-GPM UMP WITH Water IN & OUT Connections- Typical (exact location varies by model) For proper operation, piping coming from the pump and filter MUST be connected to the "IN" port of the heater.

• Locate the equipment disconnect means within 3-feet of the heater’s electrical enclosure, or as close to the heater as possible. Always satisfy applicable codes and standards. • AquaCal heat pumps are designed for copper conductors, only. Never mount disconnect directly to heat pump. -
Page 45: Sizing The Electrical Service
Reference the Equipment Data Plate • All AquaCal 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. -
Page 46: Controls Configuration & Adjustments
Level-2 programming involves configuring the heat pump microprocessor for specific site character- istics. To explain: this programming is where the heat pump microprocessor is set to operate with, or without, an external “pool equipment” controller; where sensor calibrations are performed; and where changes to other factory default parameters are made. -
