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 New Icebreaker Heat Pump ThermoLink Heat Exchanger The heart of your heat pump is the patented ThermoLink heat ex- changer. The primary cause of premature heat pump demise is the failure of the heat exchanger. Ordinary heat exchangers are made from a cupron- ickel alloy.
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.

WARNING ! 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. WARNING ! Heater contains refrigerant under high pressure. Repairs to the refrigerant circuit must not be attempted by untrained and/or unqualified individuals.
If uncertain about any instructions given herein, AquaCal Customer Support (800-786-7751) should be contacted for additional information. Note: The terms “Heat Pump” and “Heater” are used synonymously.
Every indoor installation is unique; therefore, there are no specific guidelines for this type of installation. If considering an indoor installation, you are strongly urged to contact AquaCal Engineering or Technical departments (800-786-7751) for assistance prior to proceeding.
AquaCal Technical Support for advice and guidance: (800) 786-7751. Parts and Materials: Industry technology changes much too rapidly for AquaCal to specify, with exactness, any items outside and beyond the heat pump. What is specified is that the heater must be installed in accordance with all applicable local, state, or national codes &...

Failure to heed the following may result in damage to equipment. Use of an incorrect bypass valve may compromise the heat pump’s efficiency, reliability, and may void the factory warranty. When using a bypass valve, order and install only an AquaCal PN: 2556 spring- check bypass valve.

Plumbing Schematics–Flow 70-GPM and Below (continued) Water IN & OUT Connections: For proper operation and maximum efficiency, piping coming from the pump and filter MUST be connected to the "IN" port of the heater. Likewise, connect piping returning to the pool/spa to the "OUT" port of the heater. See drawing below.
♦ In sizing power wiring, be especially aware of up-sizing requirements necessary due to wiring distances. Always satisfy applicable codes and standards. ♦ Multiple heaters installed at same site generally require special sequencing controls (AquaCal P.N.: ASC-(+number of heaters)); if yours is a multi-heater installation, contact AquaCal Technical Support (800-786-7751) for application assistance.

(Please refer to control panel diagram on previous page.) POOL/OFF/SPA (P/O/S) Toggle Switch and Sequence of Operation With the toggle switch in the OFF (O) position, the heater will be prevented from operating (however, there may be power to the unit; see "Power Light On", below). With the toggle switch positioned toward the SPA or POOL thermostat knob, with HEAT selected, and with the following conditions met: 1) water pump in operation, with water flowing through the heater, and, 2) electrical power to the heater, the heater will run if the water temperature drops below the thermostat setting.
Page 19
3. Select POOL or SPA & HEAT or COOL, Raise or Lower Associated Thermostat: ♦ Position the POOL/OFF/SPA toggle towards the POOL or SPA thermostat knob (depending on which body of water you are preparing to heat or cool). ♦ For Heating, move HEAT/COOL toggle to HEAT, then turn the selected pool or spa thermostat dial clockwise to its highest setting.
Your system can be automated with the addition of an optional AquaCal Universal Heater Controller (AquaCal part #0097TS). Using this option will save you from having to change the thermostat switch each time you change from pool to spa and back again. For details, contact your installing dealer.
Hrs. of Operation at 60º F O.A. When you start your AquaCal heat pump for the first time, the heat pump must be permitted to operate, continuously, until the desired water temperature is attained. This may take several hours, to several days, depending upon the time of the year and weather conditions.
> Check Water Temperature Change Through Condenser We recommend all AquaCal heat pump owners take advantage of this annual service starting one year after the installation of the unit. You will be surprised at the minimal cost of this service– the service is very reasonably priced for what is included.
Additionally, if the heat pump is located on the beach, or at a sea wall where salt spray and sand can become detrimental factors, more frequent service may be necessary. For service plan information, please see: Planned Maintenance Program, on previous page, and then contact AquaCal Customer Support at: 800- 786-7751.
♦ 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.
SEASONAL USE & SHUT DOWN (CONTINUED): Winterizing (Hard Freeze Conditions) WARNING ! To avoid injury from rotating equipment (fan blade), disconnect electrical power from heat pump before proceeding with INTERNAL DRAIN winterizing process. CAUTION ! Failure to properly winterize heat pump may result in serious equipment damage. Freeze damage is not covered under the heat pump warranty.

Winterizing a Heat Pump Equipped with an Internal Drain Figure 1 On the side Winterizing a Heat Pump Equipped with an External Drain 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 counterclockwise). 3.

Winterizing a Heat Pump Equipped with an External Drain CAUTION ! While the plumbing connections are in the winterized condition (not fully tightened), it is imperative pool/ spa water not be circulated through the heat pump. Loss of water through loose plumbing connections may result in damage to circulating pump, pool-spa structure, and/or other equipment.

Defrost System: Description and Troubleshooting Heat wave and AeroTemp Icebreaker models incorporate an active, time and temperature, hot-gas defrost system. Basically stated, when an evaporator coil thermostat senses a significant icing condition, the control circuit reverses the flow of refrigerant, sending hot refrigerant vapor to the outdoor coil. The effect is a rapid melting of ice and frost, and a quick return to the normal heating mode.
