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 their piston-type counterparts.
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*
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 the hot summer months. For cooler climates,
Icebreaker® heat pumps offer unique advantages over passive defrost models. Please
read more below...
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.
*Icebreaker
®
Models Only
PLEASE READ FURTHER TO BECOME FAMILIAR WITH ALL THE FEATURES, THE
SAFE OPERATION, AND THE CARE OF YOUR NEW HEAT PUMP.
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. 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
Note:
If unsuccessful using the following instructions, see: "Programming an HP7 Controller," attached following this Manual.
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 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 inst allation includes an external controller, cont act your installing dealer
for operational 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.
INST ALLER- Is heater connected to an external controller? If so, see external controller
information located on pages 44 and 47 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 SP A 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 SP A.
10
(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 external water valves appropriately to flow water to & from the body of water and
through the heater.
C. Start the water pump; the fan will st art, and within 4-minutes (depending on the status of the
controller’s internal 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.
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.
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.
, RESTARTWILLBEDELAYEDBYAPPROXIMATELY 4-MINUTES.
5. Continuous Usage and Water Around Heater:
Condensation... Af ter 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 without water flow,
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:
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”. Second Method- The thermostat set point can be lowered to a position
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: 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:
A.
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.
First Method- One of the functions of the [MODE]
B. Method 2: using the DOWN key, press the key until the desired water temperature reaches
45oF (minimum setting); then, press the DOWN key one more time, causing the display to
read “OFF”. This method is typically used in conjunction with 2-wire external controllers;
these controllers are equipped with their own thermostats.
A . Press the [POOL/SPA] key to toggle between the pool and the spa temperature set points.
B. The pool/spa LED indicator lights, located to the left of the temperature display, will confirm
the selected set point.
5. Changing The Pool Temperature Set Point:
A . Using the [POOL/SPA] key , select the POOL temperature set point. The pool set point
indicator light will confirm the selection.

7. Selecting Between
F and oC:
A. Simultaneously press and hold both the [UP ARROW] and [DOWN ARROW] keys until
[CF1] (Celsius / Fahrenheit) code appears.
B. With the [CF1] code displayed, pressing the [UP ARROW] or [DOWN ARROW] keys will
change the selection code to either “0” or “1”. Select “1” for Fahrenheit temperature display ,
or “0” for Celsius temperature display. Once the desired temperature display mode has
been selected,
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 step to the next menu parameter: [ULC] (User Lock Code).
8. User Lock Code Option [ULC]:
This Option Explained:
Heat pumps are shipped from the factory with the [ULC] option disabled. Enabling the [ULC]
function permits the heat pump owner to restrict access to the unit’s controls. With the [ULC]
function enabled, unless the correct ULC code number is entered, changes to Level-1
programming are not possible. (I.e.: Altering temperature set points, Pool/Spa selection, C/F
display changes, etc., will not be possible). The [ULC] option can be thought of as an electronic
lockable cover for the controls.
1) Press either the UP or DOWN ARROW keys; if “LOC” is momentarily displayed flowed
by “0”, the ULC feature is enabled. If “0” displays proceed to “6)” of this section;
otherwise, see number “2,” below.
2) Simultaneously press and hold both the [UP ARROW] and [DOWN ARROW] keys until
[CF1] (Celsius / Fahrenheit) code appears.
3) Press the [POOL/SPA] key once to display [ULC].
4) With [ULC] displayed, pressing either the Up or Down Arrow key will display either “1” or
“0”. Selecting “0” will allow the keypad to remain unlocked. Selecting “1” will enable the
User Lock Code option. Then to enter a lock code number, press the [POOL/SPA] key
once to display [ELC] (Enter Lock Code).
5) With [ELC] displayed, use the Up or Down arrow keys to select a lock code. The code
can be any number from “00” to “99”. The factory set lock code is “0”. 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: [CFO] (Call Flex Options).
6) Once the ULC option has been enabled, pressing any key will momentarily display
“LOC” followed by “0” (prompting the entry of the correct lock code number). To gain
access to the controller:
a. Using the [UP ARROW] key, scroll to the correct lock code number, then;
b. Press the [POOL/SPA] key… Current water temperature will be displayed… Control
setting can now be viewed or changed as desired.
c. After a period of approximately four (4) minutes, during which time no buttons have
been pressed, the controller will automatically return to the locked mode. Provided
ULC selection is set to “1,” the controller will always fail-safe in the locked mode.
d. Without knowledge of the correct lock code, and with the ULC enabled, control
adjustments will
place. The lock code may be changed any number of times by following the
instructions detailed in this section.
B. De-Activating the User Lock Code [ULC] function:
1) Following the instructions detailed previously at: “8, 6)”, press any key and enter the
user lock code number; then press the [POOL/SPA] key.
2) Immediately following the entry of the user lock code, simultaneously press and hold the
[UP ARROW] and [DOWN ARROW] keys until the code [CF1] appears on the display.
3) Then, use the [POOL/SPA] key to scroll to the [ULC] message; press the [DOWN
ARROW] key to change the display to “0”. This will disable the User lock function.
not be possible. Be certain to record your lock code in a safe
C. User Lock Code is Activated, but Pass Number is Not Known (“Back Door Entry”):
Note: Should the ULC option be enabled, and a lock code number other than the factory
default (0) be installed but is unknown, the following procedure may be followed to regain
controller programming access:
1) Simultaneously press and hold the [POOL/SPA] and [UP ARROW] keys until the display
shows “888”. This operation will reset the controller to the factory default settings.
2) When reset to the factory default settings the user lock code [ULC] is deactivated and
the user lock code number [ELC] is reset to “0.”
3) In addition, all other settings are returned to the factory defaults. If an external controller
is in use, contact AquaCal Technical Support Group (800-786-7751); ask for assistance
with re-configuring the controller for use with an external controller.
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 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. Pressing the {POOL/SPA] key will also save the
selection, and will step the controller to the next menu parameter: [LOC] (Service Lock
Code).

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 amount s of debris in the pump basket can reduce water flow. Keep
basket free of debris.
•Check for improper valve settings. A partially closed valve after the filter , or a full-open byp ass
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
•IMPORT ANT! 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.
7.4 – 7.6 ppm in pools, 7.2 – 7.8 ppm in spas
80 – 140 ppm in pools, 80 – 120 ppm in spas
200 – 400 ppm in pools and spas
1,000 – 2,000 ppm in pools,
1,500 ppm above start-up TDS in spas
CAUTION- Pool/Spa Refinishing Operations
During pool refinishing or acid cleaning, the water flow through the heater must be shut off. Water
flow to the heater must remain off until water chemistry is once again in balance and the water is
clear in appearance. Failure to follow these instructions may void heater warranty .

& 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 lock 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
W ARNING !
injury or death.
Improperly used, Pool-Sp a 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 maint ained at set point.
Y our 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 heated 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
specifications table in this manual). 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.
Pool Volume (Length X Wid th 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.
22
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.
Important !!!
Information Critical to the
Survival of Your Heater
Follows...
Freeze Protection & Extended Shut Down:
In areas where freezing conditions are a rare occurrence, allow the filtration
system to run continuously throughout the freeze period. T ypically , during light
freeze conditions, circulating (moving) water will not freeze.
In areas where freezing conditions are prevalent and sustained, the heat pump

Winterizing for Hard Freeze Conditions:
CAUTION !
Failure to properly winterize heat pump may result in serious equipment damage. Freeze
damage is not covered under the heat pump warranty .
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.

MAINTENANCE
& OPERATION (continued)
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-3 (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.

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 heater should start after an
approximate five (5) minute delay . If the heat pump still fails to st art, and the unit is not in defrost
(defrost display code is: “FS”), contact AquaCal Customer Support: 800-786-7751.
Also see page 52...
“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?
(A 9°F to 12°F dif ference 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 air outside 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.
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.
Or, as an alternate method, 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.
NOTE: The water test method will not be effective if an ionizer or ozone generator is being used to
produce the sanitizing agent.
CAUTION! If after testing, a water leak is suspected, immediately shut OFF the water pump and
contact AquaCal Customer Support: 800-786-7751.

Placement of Heater
-Indoor Installation-
Indoor installations can be problematic, and for that reason are discouraged. However, if no viable
alternative exists, indoor installations may be successfully accomplished provided very exacting criteria is addressed. 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 the
AquaCal Engineering department (800-786-7751) for assistance prior to proceeding.
-Outdoor Installation-
Service and Operational Clearances:
•To operate correctly, heat pumps require large volumes of air moving over the heat collector.
allow adequate clearance between the heat pump and walls, fences, shrubs, or other objects.
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 would reduce the overall performance of the heat pump).
•The access panel requires removal during installation and service. Do not place plumbing, or
other items, closer than 30” from the front of the heater.
Code Required Clearances:
In addition to the previously stated clearance requirements, follow all applicable local, state, and national
requirements relative to spacing from other objects or equipment.

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.
•Relocate or adjust irrigation to avoid water spray directly onto the heat pump.
•Do not locate the heat pump directly adjacent to plants, shrubs, or bushes. Doing so will prevent
proper air circulation into the unit, and may inhibit access to the heater when service is needed.
•Consult drawings on previous page (Required Installation Clearances) for proper spacing to
other objects.
Equipment Mounting Pad Requirements
•
The equipment pad shall be constructed of concrete, pressure treated wood, or other material
intended for the use.
•The equipment pad shall meet all requirements of authorities having code-related jurisdiction.
•The pad shall be elevated and placed to provide adequate drainage and support to the base of
the heat pump. The pad should be essentially level with just enough pitch to drain condensate
and any other water away from the heater.
•The pad shall extend–in all directions–(at least) 3" beyond the base of the heat pump.
•Under
no circumstances shall the heater be installed directly onto the earth.
Anchoring Heater to Pad
•Follow all relevant local, state, or national requirements regarding wind load anchoring.
•When anchoring is required, use AquaCal optional Hurricane Anchoring Kits.
- AquaCal anchoring kit s satisfy , completely , the very stringent Florida Building Code
Section 301.13: Wind Anchoring Requirement s.
-Contact AquaCal Parts Group (800-785-7751) to obtain the correct anchoring kit for the

Microprocessor Mode Jumper Positioning
Mode Jumper Explained
The HP7R microprocessor is designed to operate as a Heat-Only or a Heating & Cooling controller.
The selection between the two choices is made through the positioning of a mode jumper contained
on the microprocessor board. The position of the jumper is set at the factory, and is dependant upon
the design of the heater being controlled. Heaters designed to heat only, have the microprocessor
mode jumper set in the heat-only mode; heaters capable of both heating and cooling (reversing), have
their microprocessor mode jumper set to permit control of both heating and cooling.
Important: The position of the mode jumper must match the capabilities of the heat pump. Simply
placing the mode jumper to the heating and cooling position, with a heater designed to heat only , will
not make a heat-only heater heat & cool. In fact, a mis-positioned mode jumper will cause heater
control difficulties.
Verifying the Mode Jumper Position is Correct
1. Apply electrical power to the heater .
2. Review the available modes by repeatedly pressing the [MODE] key:
A.
Heat-Only Models: the [MODE] key functions should appear as: [OFF] and [HEA].
B.
Heat-Cool Models (Icebreakers): the [MODE] key functions should appear as: [OFF], [HEA],
[COO], and [AHC].
3. If the modes do not display correctly for the heater being serviced, the mode selector jumper,
located on the microprocessor PC board, is likely placed in the wrong position. To correct this
condition, the jumper will need to be repositioned. See repositioning instructions, below.
Repositioning the Mode Jumper
Use this procedure if [MODE] key functions indicate jumper positioning is incorrect. The mode
jumper is located on the microprocessor controller board, within the heater’s electrical enclosure.

1. To access the jumper, disconnect electrical power and remove the heater front entry panel; then,
remove the metal cover from heater electrical enclosure. For layout details of the PC control
board, see figures on next page.
2. Locate the mode jumper in the upper right hand corner of the PC control board; per the figures
on the following page, identify the correct location for the jumper. If the jumper is found to be
incorrectly positioned, gently disengage the jumper by pulling it directly away from the control
board.

3. Correctly reposition the jumper , leaving one pin uncovered.
(2) pins: one always being the middle pin, and the other the correct pin for the features of the
heat pump.
The microprocessor controller monitors the heater’s air-coil temperature, minimizing air-coil freezeup during cooler weather conditions. If the controller senses air-coil temperatures conductive to making ice, the heater’s compressor operation is interrupted while the fan is allowed to continue in operation.
With the compressor off, the air-coil begins to warm to the surrounding air temperature. When air-coil
temperatures rise above approximately 38
In the event air temperatures remain below approximately 38
the air temperature rises above 38oF. The unit will not heat the water as long as the compressor
remains off.
During defrost cycles, when the controller has stopped compressor operation, the display will read:
[FS].
DEFROST CYCLE (HEAT & COOL UNITS):
The microprocessor controller, in conjunction with the defrost sensor , constantly monitors the heater’s
evaporator (air-coil) temperature. Should the controller sense ice or frost has formed on the evaporator, suf ficient in amount as to af fect the heater’s performance, an active defrost cycle (more below) is
initiated. Before initiating a defrost command, the controller defrost logic looks at both the air-coil
temperature, and the length of time the coil has remained at an ice-making temperature.
Active defrost involves using hot refrigerant gas, from the compressor, to rapidly remove ice or frost
from the evaporator coil. In practice, during a hot gas defrost cycle, valving, internal within the refrigerant system, reverses the flow of the refrigerant; this reversal of flow temporarily makes the air-coil the
condenser. During hot gas defrost, the air-coil warms very quickly, and accumulated ice and frost is
rapidly melted. Under most conditions the evaporator will be completely cleared in under 5-minutes.
HEAT & COOL DEFROST SEQUENCE DETAILS:
•When the controller senses air-coil temperatures conductive to making ice, the unit will enter a
50-minute defrost delay (counting) period.
o
F, the compressor is restarted and heating resumes.
o
F, the compressor will remain off until
•During the counting period, the fan and compressor will continue to operate, and the water will
continue to be heated. During the counting period it is normal to see a moderate amount of frost
and ice formation on the air coil.
•If, after the 50-minute counting period, the controller senses a need to defrost:
1. The refrigerant circuit reversing valve will be activated, changing the flow of hot refrigerant
gas from the pool water heat exchanger to the air-coil.
2. Fan operation will be suspended, permitting maximum heating of the air-coil.
3. The reverse cycle will continue until either:
A . The air-coil attains a predetermined temperature (indicative of total defrost), or;
B. Until 5-minutes have elapsed (regardless of total defrost having occurred).
•During hot gas defrost cycles, the compressor will not deactivate; rather, the compressor will
continue operation throughout the sequence. Upon completion of the defrost cycle (as
terminated per “A” or “B,” above), the reversing valve will be deactivated, fan operation will
recommence, and water heating will resume.

Water Flow (Pressure) Switch Adjustment
Occasionally, plumbing system design features will create a situation whereas the heater will abnormally cycle on the water flow circuit. This situation will be evident if the circulator pump is operating,
the filter is clean, and all water valves are set to flow water through the heater– but the error code:
“FLO” remains displayed (or displays intermittently). In these rare instances where the factory water

CONTINUOUS USAGE AND WATER AROUND UNIT
o If you have followed the directions up to this point, you should be on your way to
enjoying a warm pool or hot spa.
o After the heat pump has been running for some time, you may see water present
around the heater. This water is condensation produced as a by-product of
transferring heat from the air to your pool or spa. If the humidity is high, water
quantities of 6-8 gallons per hour are not uncommon. Conversely, a lowhumidity condition may result in no condensation being produced.
REQUIRED HOURS OF POOL PUMP OPERATION
S
OME POOL SYSTEMS UTILIZE A TIMER TO CONTROL THE POOL FILTER PUMP ON A TIME-OF-DAY
BASIS
. I
F YOUR POOL SYSTEM INCORPORATES A TIMER, USE THE FOLLOWING INSTRUCTIONS
o It will be necessary to allow your pool circulator pump to run continuously until
the pool has reached the desired temperature.
o If a timer controls your pump, it will be necessary to override the timer to
temporarily allow for 24-hr. pump operation.
o Once the desired temperature has been obtained (this may take up to four days),
you should reset your pump time clock for normal operating hours.
REMEMBER … THE HEAT PUMP CAN ONLY OPERATE WHEN THE CIRCULATOR
PUMP IS RUNNING. THEREFORE, IN ORDER TO KEEP UP WITH INCREASED HEAT
LOSS DURING COOLER WEATHER
DAILY HOURS OF OPERATION
, IT MAY BE NECESSARY TO EXTEND THE PUMP’S

:
TO SHUT THE UNIT OFF
o The unit can be stopped by switching off the electrical supply or by setting the
desired temperature lower than the actual water temperature.
o The unit will display “OFF” if the desired water temperature is set below 60°F.
