IMPORTANT FEATURES OF YOUR NEW HEAT PUMP
ThermoLink Heat Exchanger:
The heart of your heat pump is the patented ThermoLink heat exchanger. The primary 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. Once the heat exchanger fails, the heat pump is ruined. The ThermoLink heat exchanger tube is made from titanium, and is virtually impervious to water-chemistry damage.
Electronic
Controller:
State-of-the-art, solid-state electronic controller, maintains water temperature within 1ºF of set point. Controller also permits user to predefine different Pool and Spa water temperature set points.
Corrosion-Resistant Cabinet:
Hybrid design utilizes the best features of finished aluminum and resilient ABS plastic. The base, being ABS material, will never rust or corrode. The remainder of the cabinet is constructed from sturdy, marine-grade, powder-coated aluminum.
PLEASE SPEND A FEW MINUTES READING FURTHER TO BECOME FAMILIAR WITH ALL THE FEATURES, THE SAFE OPERATION, AND THE CARE OF YOUR NEW HEAT PUMP.

SAFETY INFORMATION
Used and maintained properly, your heat pump will provide year-upon-year of safe and economical service.
However, as with any mechanical or electrical device, to get the most from your heat pump–while insuring personal safety for you and others–certain operational and maintenance factors must be observed.
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 experienced service personnel. Should you, the owner, suspect your heat pump is not performing properly, by referring to the section in this manual entitled: "Troubleshooting", you will be able to determine if a call for service is required. 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. Warranties may be voided if the heater has been used, maintained, or repaired improperly.
In addition to possible voiding of warranties: unapproved installation methods, nonstandard modifications, poor or incorrect maintenance, service by unqualified personnel, or improper use of this unit, may result in personal injury
and/or property damage. For personal safety and to avoid damage to equipment, it is important that safety instructions displayed on the heat pump, and within this manual, are read, understood, and followed.
Throughout this manual the following two safety signals are placed where particular care is required. Please note "WARNING" relates to personal safety, while "CAUTION" signals promote avoiding damage to equipment.

QUICK START & STOP
This brief information is provided as an aide to installers, service personnel, and owners. The intent of this section is to provide rapid access to (only) very basic operational information. Individuals who will be routinely using, installing, maintaining and servicing this heat pump are strongly encouraged to read this entire manual. If uncertain about any instructions given herein, AquaCal Customer Support (800-786-7751) should
be contacted for additional information.
Start Up
1.Set pump controls to allow for temporary, continuous operation.
2.With pump OFF, position water valves to heat the POOL or SPA.
3.Rotate both thermostats counterclockwise to lowest temperature setting.
4.Depending on valve settings (per #2, above), position the POOL/OFF/SPA toggle switch to point at either the POOL or SPA thermostat knob.
5.Ensure power is supplied to the heater, then start the water pump; the POWER and FLOW lights should now both be lit. Permit the water pump to operate for five (5) minutes before proceeding
How to Operate the Controls - Pool or Spa
1.Turn the selected pool or spa thermostat dial clockwise to its highest setting.
2.The heat pump will start and begin to heat the pool or spa.
NOTE: The heat pump has a time delay so if it shuts down for any reason, it will not restart for approximately five (5) minutes.
3.The typical spa may take several hours to initially heat up, while a pool may take several days. Heating time will depend on the volume of water, water temperature, and the climatic conditions at the time of start-up. (Also see Calculating Initial Heating Time.)
4.When the pool or spa reaches the desired temperature, slowly rotate the thermostat knob counterclockwise until the heat pump (just) stops. The thermostat is now set to automatically maintain this temperature.
Time Clock Programming
Once the heat pump has brought the pool or spa up to temperature, it will be necessary to reset the pump controls. Be sure to allow enough running time for the heat pump to replace lost heat. This time will vary depending upon the time of year. Colder months require longer running times—usually eight to twelve hours.
Manual Switching From Pool to Spa
NOTE: It is best to stop the pump while repositioning valves.
1.Open spa valves and close pool valves.
2.With the spa filter pump running for at least five minutes, move the POOL/OFF/SPA toggle switch from the Pool Setting to the Spa Setting.
3.Turn the Spa thermostat clockwise until it stops (104 F).
4.The typical spa may take several hours to initially heat up. Heating time all depends on the volume of water, water temperature and the climatic conditions at the time of start-up.
5.When the spa reaches the desired temperature (104 F is maximum), slowly rotate the thermostat knob counterclockwise until the heat pump (just) stops. The spa thermostat is now set to automatically maintain this temperature any time the spa thermostat has been selected.
To Stop the Heat Pump
The unit can be stopped by switching off the electrical supply or by setting the desired temperature lower than the actual water temperature.

Refrigerant Circuit Performance Charts
Use of ChartsInformation for the Technician:
The charts are intended for use by trained and qualified air-conditioning and refrigeration technicians only. The charts are compiled specifically for evaluation and diagnostic purposes, and are NOT designed for use as charging charts. To apply the chart data to actual conditions: gather the operating pressures, suction tube superheat & liquid line subcooling values, water temperature change through the heater, and the total unit amps. Locate a chart that most closely represents current actual conditions. Readings obtained that differ from the charts in excess of 10% (+ or -), may indicate a problem within the mechanical refrigeration system. Reference: Troubleshooting Refrigerant Circuit Problems, following the charts. Some interpolation between charts will be necessary should actual conditions not align reasonably well with the charts. Should refrigerant circuit readings appear normal, but not the Water DT value, the likely cause will be water flow above or below 45 GPM. (TropiCal refrigerant circuits will perform acceptably with condenser water flow between 20 to 70 GPM.)
