“You can rest assured

knowing your new heat

pump is of the highest quality and efficiency,

Moreover, should you decide you would like AquaCal to provide regular inspection and maintenance of your heat pump— which we do recommend—you will find AquaCal’s factory-trained service staff is the largest and most-qualified in the pool & spa heat pump industry .

and is designed and

built to provide years

of trouble-fr ee

operation.”

Import ant 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.

Scroll Compressor

50% fewer moving parts than standard piston-type compressors. This equates to much improved reliability and improved efficiency. Scroll compressors are also much quieter in operation than piston-type compressors.

Digital Controller

Digitally-based microprocessor, controls water temperature to within 1º Fahrenheit of set point. Controller also permits user to predefine different pool and spa water temperatures, and to prevent tampering by locking out controls via a pass code.

Heat & Cool Capability*

heat pumps offer unique advantages over passive defrost models. Please

Hot Gas Defrost*

Your Icebreaker® heat pump is uniquely equipped for active defrost. Active defrost involves directing hot refrigerant gas to the heat collector, melting accumulated ice away in a matter of a few minutes—then right back to heating. Standard heat pumps may remain “off in defrost” for extended periods during very cold weather. Because of its ability to continue to operate even during freezing weather, your Icebreaker extends the swimming season longer than any other heat pump.

Corrosion-Proof Cabinet

The cabinet, being made from resilient, UV-Protected ABS material, can never rust, fade or corrode. You can expect the cabinet to retain a like-new appearance with only an occasional wash down and—if so desired—a quick waxing.

HOW A HEA T PUMP WORKS

THE FOLLOWING EXPLANATION IS PROVIDED TO HELP YOU IN UNDERSTANDING

WHA T

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. Rather, heat pumps simply transfer heat from the outside air into the water.

If one considers absolute “0”–the point where all heat is absent–occurs at 459º F ahrenheit below zero, 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.

SAFETY INFORMA TION

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. W arr anties ma y 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 "CA UTION" signals promote avoiding damage to equipment.

Getting Started

HEATING- QUICK ST ART & 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. Herein, the terms: Heat Pump, Heater, and Unit are used synonymously.

These instructions are intended for local control of a heat pump, independent of an external controller. Owners: if your installation includes an external controller, contact your installing dealer for operational instructions.

These are instructions to quick-start in the HEATING mode...Owners of Heat-Cool units, in order to utilize all features of their heater, will cert ainly want to also refer to: ning on page-14 of this manual.

1. Verify Electrical Power is Present at Heater:

A . Ensure that the unit has electrical power connected; the heater controller display should

be illuminated;

B. If the display is blank, be certain the electrical breaker, and heater disconnect, are

switched to “ON”;

C. For now, leave the water circulation pump OFF.

Owner Level Programming, begin-

2. Set the Heater Controls (Refer to Control Panel Layout, Pg-12): OWNER- If heater is connected to a Call-Flex controller, also see Call-Flex programming

located in INST ALLER- Is heater connected to an external controller? See:

beginning on page-31 this manual. A. The owner settings can be set without water flowing. Once the heater has electrical power

connected, with water not flowing, the display should read FLO;

B. Press the MODE button until the HEAT (HEA) indication displays. This action will enable

the remaining programming keys;

C. Using the POOL / SPA selector key, select the POOL mode. The chosen mode will be

verified by an illuminated indicator light, located on the left side of the display , showing that the POOL control has been selected (If heating just a spa, using the DOWN arrow

key, lower the POOL temperature until OFF is displayed; then proceed to Step-E. ). 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 (If heating just a POOL, using the DOWN arrow key, lower the SPA temperature until

OFF is displayed.); F. The heat pump controls are now set to maintain the desired water temperature for the

POOL and/or SPA.

Owner Level Programming, beginning on page-14 of this manual.

Dealer-Specific Instructions,

(Quick-Start & Stop Continued Next Page)

HEATING-QUICK START & STOP (continued):

3. To Begin Heating:

A . Verify MODE is set to: HEAT ; then, depending on which body of water is to be heated, use the

POOL / SPA selector key to select POOL or SPA ;

B. Position external water valves appropriately to flow water to & from the body of water and

through the heater;

C. Start the water pump...Within 4-minutes, depending on the status of the controller’s internal

time delay , the heater will st art. The selected body of water will be brought to temperature and maintained per the setting determined previously in: “Set the Heater Controls”;

D. In operation, whenever the actual (displayed) water temperature falls below the desired set

point, after an initial time delay of 4-minutes, the unit will begin heating .

NOTE: THE HEAT CONTROLLER INCORPORATES AN ANTI-SHORT CYCLE TIME DELAY. SHOULD OPERATION BE

INTERRUPTED

4. Program Filter Pump Run Time:

Most pool/spa systems utilize a timer or multifunction controller to manage filter pump run times.” If your system incorporates such a device, follow the instructions below:

A . It will be necessary to allow the filter pump to run continuously until the water has reached the

desired temperature. If a timer controls the pool filter pump, it will be necessary to override the timer to allow 24-hr. operation.

B. Once the desired temperature has been obtained (2-4 days), reset the pump control device.

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. The increased run time is necessary in order to keep up with increased, weather-related heat losses.

, RESTART WILL BE DELAYED BY APPROXIMATELY 4-MINUTES.

5. Continuous Usage and Water Around Heater:

Condensation... After the heat pump has been operating for some time, water may be observed surrounding the heater. The moisture seen is condensation produced as a by-product of transferring heat from the air into the pool or spa water. Quantities of 6-8 gallons of water produced per hour are common if the air humidity is high. Conversely , a low humidity condition may result in no condensation being produced. (To troubleshoot, see page-26, “W ater Coming from the Heat Pump.”)

6. To Stop the Heat Pump:

A. Select: OFF via the MODE selector. This method of shut down preserves the controller

settings;

B. An interruption of water flow–such as when a pump timer is in control–will, also, cease heat

pump operation.

OF THE NORMAL OPERATION OF THE HEATER:

FLO.....No Water Flow Detected. This code appears whenever the circulating

pump is off, or when the heater is not receiving correct water flow.

OFF..... System is Off. This code appears whenever heater has been turned off

via the mode selector button, or when the temperature set point has been lowered below 45

CFI...... Celsius/Fahrenheit Selection. This is a programming entry point to select

in which format the water temperature will be displayed.

ULC.....User Lock Code. This is a programming entry point; when activated,

steps to the next menu level: ELC.

ELC.....Enter Lock Code. This a programming entry point; permits end user to

select a secret code, thereby limiting access to the owner settings.

CFO.....Call Flex Options. This is a programming entry point; when used in

conjunction with a AquaCal Call/Flex add on kit, permits the use of CALL or FLEX options.

FS....... Heater in Defrost Mode. This code appears as a normal display during

periods of lower air temperatures. Two possibilities follow: Heat-Only Units: Fan continues to run and compressor is off. Compressor

will restart when air coil temperature rises to approximately 38°F. Heat-Cooling (reversing) Units (Applicable in Heat Mode Only): if a

defrost cycle is necessary, the unit’s reversing valve will be activated. While the reversing valve is activated, the fan operation will be suspended to permit maximum heating of the air-coil. The reverse-cycle will continue until the air-coil reaches a set temperature, or until 4-Minutes has elapsed. Upon completion of the defrost cycle, the reversing valve will be deactivated; normal fan and heating operation will resume. During hot-gas defrost cycles, the compressor will not deactivate; rather, it will continue in operation throughout the sequence.

LOC.....This is a Service Entry Point (not intended for use by the owner). The

[LOC] code permits service personal to enter a factory code for access to adjustable calibration and site-dependant setup parameters. Service adjustments are available to authorized installation and service personnel, only.

Start Up & Setting Operating Controls

Owner-Level Programming Instructions (Complete)

Covered within this section are features and settings typically accessed first by the installer, and then remaining accessible by the end user (owner). These features reside at the Level-1 access point within the microprocessor.

1. Applying Power to The Controller:

A . When power is first applied, the controller performs a lamp test and the display will read

[888]. Following [888] the software version will display briefly;

B. The control will then display the actual water temperature, provided the circulating pump is

operating, and adequate water is flowing through the heater;

C. If the pool-circulating pump is off, the control will display: [FLO]. This code message

indicates no (or insufficient) water is being circulated through the heat pump.

2. Starting the Heat Pump:

A. Once electrical power is supplied to the heat pump, sufficient water is circulating, and the

heater controller has successfully completed its self-test, the heater is ready to operate;

B. The heat pump is shipped with the controller [MODE] function set to “OFF”. There are two

ways to switch the heat pump OFF: button is “OFF”. below the minimum temperature setting (45 “OFF”. To switch the unit ON, first use the mode button to select the HEAT mode— for Heat Only models—or, if the heat pump is a Heat and Cool model, use the mode button to select one of the following modes: HEA T, COOL, or ACH (Auto-changer over). In the [OFF] mode, the actual water temperature will be displayed as long as the circulating pump is operational and correct water flow is present. In the event water is not circulating through the heat pump (or flow is insufficient), the controller will display the [FLO] (No Water Flow) code message.

C. Using the UP ARROW key, increase the desired temperature until it exceeds the value of the

actual temperature displayed. (Note: See # “8,” later in this section, if “000” is displayed upon pressing either the up or down arrow keys.) Once the desired temperature has been entered, the display will read the actual temperature and the heat pump will start to operate. Both the compressor and the fan must be operating before the “Heating” LED will illuminate.

(Note: When MODE function is OFF, the current water temperature will be displayed; no functions, values, or programming will be available for adjustment.)

3. Turning The Heat Pump Off:

Method 1: using the [MODE] key, depress the key until the display reads “OFF” The heater will shut off and remain off until the [MODE] key is used the select an operational mode. This is the preferred method for shutting off the heat pump.

9. Selecting Call-Flex Pump Options [CFO]:

General Information:

The Call-Flex option automatically adjusts the run time of the water circulator pump, and heater, based upon changing weather conditions. Without Call-Flex, as weather conditions grow progressively cooler during winter months, or when unusually cold weather occurs, the run duration of the circulator pump may require manual adjustments to permit the heater to maintain or reattain desired water temperature (the water pump must be running in order for the heater to operate). Likewise, without Call-Flex, one must remember to reset the pump run controls following the cold weather event. The Call-Flex option greatly reduces the need for seasonal, manually-made, pump run time adjustments. Call-Flex is a dealer-installed option that does come with every heater; if unsure, check with the installing dealer to determine if a call-flex kit was part of the original installation. If Call-Flex was not part of the installation, and you would like

to have Call-Flex added, your dealer can do so...contact the installing dealer . If the installation is equipped with the Call-Flex option, the following steps are used to control the

Call-Flex features: A. Simultaneously depress and hold the [UP ARROW] and [DOWN ARROW] keys until the

display shows “CF1”. Depress the [POOL/SPA] key three times to scroll the display to [CFO].

B. With the [CFO] (Call-Flex Options) code displayed, use the Up or Down keys to select “0” to

disable the Call Flex Options, “1” to enable the Call Option, or “2” to enable the Flex Option. Not pressing any buttons for 15-seconds will allow the controller to save the selection and return to the normal operating mode. Pressing the {POOL/SPA] key will also save the selection, and will step the controller to the next menu parameter: [LOC] (Service Lock Code).
