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. For example, your heat pump is up to 400% more efficient than gas, and, when compared to electric resistance heat, your heat pump is nearly 600% more effective. You can rest assured your new heat pump is of the highest quality and efficiency, and is designed and built to provide years of trouble-free operation.

Moreover, should you ever require help in using or maintaining your heat pump, you will find AquaCal’s customer and technical support staff to be the largest, most qualified, and—of utmost importance—the most easily accessed customer service team in the pool & spa heat pump industry.

“You can rest assured

knowing your new heat

pump is of the highest quality and efficiency,

and is designed and

built to provide years

of trouble-free

operation.”

Important Features of Your

New Heat Pump

ThermoLink® Heat Exchanger

The heart of your heat pump is the patented ThermoLink® heat exchanger. One of the primary causes 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 water chemistry damage.

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 their piston-type counterparts. And, while all AquuaCal heat pumps are known for their low operating noise levels, if yours is a SuperQuiet likely your heat pump will be quieter than any other item on the pool equipment pad.

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.

Corrosion-Proof Cabinet

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

Heat & Cool Capability*

Puts you in full control, year round... Warms your pool or spa with the reliability and efficiency of our other heat pumps, but, with the flip of a switch, can also cool your pool or spa to refreshing temperatures during hot summer months. For cooler climates, Heat & Cool heat pumps offer unique advantages over passive defrost models. Please read more below...

Hot Gas Defrost*

Hot gas defrost heat pumps are uniquely equipped for an active defrost cycle. Active defrost involves directing hot refrigerant vapor to the heat collector, melting accumulated ice away in a matter of a few minutes... then right back to heating. Standard defrost heat pumps may remain “off in defrost” for extended periods during very cold weather. Because of their ability to continue to operate–even during freezing weather–hot gas defrost models extend the swimming season longer than any standard-defrost heat pump.

These features available in Icebreaker®and SuperQuietTM Models Only.

PLEASE READ FURTHER TO BECOME FAMILIAR WITH ALL THE FEATURES, THE SAFE

OPERATION, AND THE CARE OF YOUR NEW HEAT PUMP.

HOW A HEAT PUMP WORKS

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

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.

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 voiding the manufacturer’s warranty... unapproved installation methods, nonstandard modifications, poor or incorrect maintenance, service by unqualified personnel, or improper use of the heater may result in personal injury and/or property damage. For personal safety, and to avoid damage to equipment, follow all safety instructions displayed on the heat pump and within this manual.

Getting Started

HEATING- 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 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, or the external controller manufacturer, for external controller operating instructions.

These instructions are for quick-starting in the HEATING mode... Owners of Heat-Cool units, in order to utilize all features of their heater, will certainly want to also refer to: ming, beginning 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 Program-

2. Set the Heater Controls (Refer to Control Panel Layout, Pg-12):

OWNER- If heater is connected to a Call-Flex controller, also see “Selecting Call-Flex Pump Options,” located on page-17 of this manual.

INSTALLER- Is heater connected to an external controller? If so, see external controller information located on pages 41 and 44 of this manual.

A. The user/owner settings can be made 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. An illuminated POOL indicator

light, located on the left side of the display, will confirm the POOL control has been selected. If heating only 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. An illuminated SPA indicator light, located on the left side of the display, will confirm the SPA control has been selected. If heating only 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.

(Quick-Start & Stop Continued Next Page)

HEATING-QUICK START & STOP (continued):

3. To Begin Heating:

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

use the POOL / SPA selector key to select POOL or SPA.

B. Position water valves to flow water from the pool or spa, through the heater, and back to the

pool or spa.

C. Start the water pump; the fan will start, and after 4-minute time delay the unit will begin

heating. 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 HEATER 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 (1-4 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.

, COMPRESSOR 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 normal 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. (If water around unit seems excessive, to troubleshoot, see page-26, “Water 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 halt heat

pump operation.

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 (the owner). These features reside at the Level-1 access point within the microprocessor. Note: if preferred, all programming may be performed with waiting to start the water pump as the last step in the set up and run process.

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. MODE Controls Explained, and Starting the Heat Pump:

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 (45oF); this action will cause the display to read “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: HEAT, 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, press 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 not come with every heater; if unsure, check with the installing dealer to determine if a call-flex kit was part of the original installation.

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 press and hold the [UP ARROW] and [DOWN ARROW] keys until the

display shows “CF1”. Press 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.

MAINTENANCE

& OPERATION (continued)

Maintain 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.

• Similar to a dirty filter, large amounts of debris in the pump and skimmer baskets can reduce water flow. Keep baskets free of debris.

• Check for improper valve settings. A partially closed valve after the filter, or a full-open bypass around the heater, will cause insufficient water flow through heater.

• If the conditions listed above remain unresolved, the water flow through the heater may be reduced to a point where internal safety devices (i.e.: “HP” or “HP5”) shut the heater off.

• Before calling for service, always check the filter, the pump basket, and water valve positions. If the problem persists, please call AquaCal Customer Support at: (800)786-7751.

Control Water Chemistry

• IMPORTANT! Your heat pump is engineered for exceptional durability and reliability. And, this

unit’s heat exchanger—being equipped with titanium tubing—will be nearly impervious to water chemistry damage. However, other components of the heater, and the remainder of the pool/spa equipment in general, may be susceptible to damage from prolonged exposure to unbalanced water chemistry. Likewise, bathers may be exposed to health risks if water chemistry is not properly maintained.

• For the longevity of the entire pool/spa installation, and for the safety of bathers, it is strongly

recommended the water chemistry be checked regularly and maintained within proper norms. Please see the table, below, for a complete listing of recommended water chemistry levels.

& OPERATION (continued)

Control Irrigation and Storm Run Off

• Control Irrigation: In regions were wells are used for irrigation, water quality is sometimes poor, and water spray can damage heater components. Regardless of water quality, it is important that irrigation be directed away from the heat pump.

• Prevent rain water runoff from pouring directly into the heater. The heater is designed to withstand normal rainfall, but solid streams of water from roof drip-lines may eventually damage heat pump components.

• If the heat pump resides beneath a roof edge, to promote heat pump longevity, a rain leader (gutter), or rain shield, will be necessary.

Maintain Proper Clearances Around Heater

• For maximum efficiency, proper air flow clearances around heater must be maintained.

• It is important to keep the area immediately adjacent to the heat pump clear of items such as

shrubs and bushes, lawn furniture, chemicals containers, etc. These items can prevent air from circulating fully through the heater, and will result in inefficient operation or damage to the heat pump.

• In addition, do not place objects on top of the heat pump; doing so will block the air from exiting

the heater, and will result in damage to the compressor and fan motor.

• Proper clearances are also necessary in order to access the working parts of your heater. A

heater that is easy to "get to," will be a heater that is easy to maintain; service and maintenance personnel will thank you for keeping the area around your heater unobstructed.

• Please see diagrams, below, for specific clearance requirements.

Heating Tips

Heating in Cooler Weather...

Late night and early morning, generally being the coolest times of the day, are least efficient for heating. For most efficient heating operation, heat pumps should be timed to operate during the warmest, daylight portions of the day. Conversely, if cooling a pool, it is best to run the equipment at night. Please set water pump and heat pump controls accordingly.

Pool/Spa Blankets...

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. (Idea...Contact AquaCal Customer Support (800-786-7751) to learn about Liquid Blanket innovations.)

Failure to heed the following may result in permanent

WARNING !

injury or death.

Improperly used, Pool-Spa blankets can become a drowning risk to people and pets. Blankets are not safety covers. They are not designed to support the weight of a person or pet. Never enter a pool until the blanket is completely removed (under no circumstances should anyone swim under the blanket). Follow all safety recommendations of the blanket manufacturer.

Pool and Spa Combination Heating...

Everything stated for heating a pool applies for heating a spa—only the volume of water being heated is different. Your heat pump comes equipped with two thermostats. One thermostat is for the pool and the other is for the spa. Simply position the pool and spa isolation valves as directed by your installer; select the appropriate thermostat (pool or spa), whichever you are heating, and with electrical power and water flow supplied to the heater, the water will be maintained at set point.

Your system can be automated with the addition of an optional Using this option will save you from having to change the thermostat selector switch each time you change from pool-to-spa and back again. Or, add a Universal Heater Controller (P.N. 0097TS) and gain not only automatic thermostat switching, but also automated spa/pool water valve operation. For details, contact the installer, the distributing dealer, or AquaCal Customer Support (800-786-7751).

External Flow Switch Kit (P.N. 0040S).

Spa Heating & Spa Setback Option...

Air blowing into your spa, while it is being brought to temperature, will very often neutralize or partially counteract the heat being put into the spa by the heater; this added heat loss equates to increased time to bring your spa to desired temperature. When heating a spa, be sure to turn off the air blower. Air induced through the spa jets should also be eliminated, during warm-up, whenever possible.

If your heater is being used to only heat a spa, the simply set the pool control at a point 10-15º F below desired spa heat temperature and select the pool thermostat. This method allows the spa–when not in use–to be held at a heated temperature, but somewhat lower than normal spa-use temperature. One would want to blanket the spa if using this setback method. Using spa setback will result in reduced warm up periods over full, cold starts.

POOL thermostat can be used as a setback control:

MAINTENANCE

& OPERATION (continued)

Calculating Initial Heating Time

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.

Next, find the approximate BTU output of your heat pump at the current ambient air temperature; see product literature at: www.aquacal.com, or contact AquaCal Customer Support (800-786-7751).

Finally, decide upon the temperature at which you plan to maintain your pool or spa.

The following work sheet can be used to calculate approximately how long it will take your heater to bring your pool or spa up to temperature. Keep in mind heating times will vary somewhat due to weather conditions during the period that the heater is in use; use of a pool blanket can dramatically improve heat up and heat maintenance performance.

Pool Volume (Length X Width X Average Depth) = _________ Pool Cubic Feet

X Gallons per cubic ft.(7.5) = _________ Pool Gallonage

X Pounds per Gallon (8.3) = _________ Pounds of Water

How many degrees do you want to raise the temperature of the pool?

# of Degrees _________ X Pounds of Water (per above) = __________ BTU’s Required

BTU’s Required (per above) ________

Optional Cold Weather Adjustment Factor:

Hrs. of Operation (per above) ______ X 1.25 (60º F outside air (O.A.) Temperature Factor) =

______Hrs. of Operation at 60º F O.A.

÷ BTU Output of Heater = ______ Hrs. of Operation

At Start Up: Continuous Circulator 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.

If a time clock or similar device controls the operating times of the water circulating pump, temporarily override the water pump controller, allowing for 24-hour, continuous water pump operation.

Once the body of water has reached the desired temperature, the water pump controller can be reset.

MAINTENANCE

& OPERATION (continued)

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.

• During periods when heating or cooling is not desired, leave heater controls in the OFF position.

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 counterclockwise).

3. Locate the hand drain plug at lower, front corner of heater. See figure below. (position may vary between models). Remove plug.

4. Permit all of the water to drain out of the condenser and then replace the plug; thread the plug in clockwise until just snug, then apply an additional 1/8 turn.

5. To prevent insects and vermin from entering the plumbing during the winterized period, partially reconnect the two (2) plumbing connection unions: couple each union one or two threads; this will permit condensation to drain, but will prevent most insects and animals from entering the plumbing circuit.

Next Season: To ready the heat pump for use, simply retighten plumbing connection unions.

6. Hand-tight is generally sufficient.

TROUBLESHOOTING

Heat Pump Fails to Operate...

Is the display illuminated?

If not, ensure the main breaker (located at the power supply panel) and the disconnect switch (located near the heat pump) are both turned ON.

Is the code “FLO” displayed?

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.

Is the Pool or Spa thermostat selected for the correct body of water to be heated, and have you tried selecting a higher temperature setting?

If not, the actual water temperature may be above that of the selected thermostat. Raise the desired water temperature above the actual water temperature; the fan should start, and after approximately four (4) minutes, the “Heating” light should illuminate. If the heat pump still fails to start, and the unit is not in defrost (heat-only unit defrost display code is: “FS”), contact AquaCal Customer Support: 800-786-7751.

Also see page 51...

“Error Codes”

Heat Pump Running... but is it Heating?

Is the air blowing out of the top of the unit noticeably cooler than the surrounding air?

(With heating indicator light illuminated, 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. The heat pump needs good airflow to operate at peak efficiency.

How many hours/day does the circulating pump operate?

Cooler weather conditions, or heating to a higher than normal temperature, may necessitate running the heat pump for a longer period of time. Was the heater sized considering the use of a pool blanket (check with installing dealer)? A blanket can be useful in permitting shorter run times, in turn leading to substantial energy cost savings.

What is the outside air temperature?

The heat pump may be in the defrost mode if air temperatures are below 50°F. With Heat-Only models, if the heater is in defrost, the code: ”FS” will be displayed. If air temperatures are not cold, but the heater remains in defrost, contact AquaCal Customer Support at: 800-786-7751.

Water Coming from the Heat Pump...

Is it a leak or just condensation from normal operation? Here's how to find out.

Test the water draining out the heater base for the presence of the sanitizer being used in the pool or spa. Using a water test kit, or a test strip, check a sample of the water for chlorine or bromine. If the sample tests positive for sanitizer, call AquaCal for service at: 800-786-7751. If the test is negative, the water is probably harmless condensate.

Or, as an alternate method, shut the heat pump off, leaving the circulation pump running. Within a few hours, there should be a marked reduction in the amount of water seen around the bottom of the heat pump. If the water appears to be drying up, the water is probably harmless condensate, indicative of normal operation.

NOTE: The water test method will
