T
eam
Dear Owner:
ongratulations on your wise decision to make an AquaCal heat pump part of
your home. Since 1981, AquaCal has has been recognized as the worldwide
C
leader in the manufacture of swimming pool & spa heat pumps. Y our new heat
pump is not only a great investment, but
also the most cost efficient 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. Y ou 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-fr ee
operation.”

Heat Pump Options
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® heat exchanger tube is made from titanium, and is virtually impervious to
water chemistry damage.
Microprocessor 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. The microprosser controller also provides superior defrost control, and self diagnostics.
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. And, while all AquuaCal heat pumps are
known for their low operating noise levels, if yours is a SuperQuietTM model, it’s very
likely your heat pump will be quieter than any other item on the pool equipment pad.
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 v apor 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.

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 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: (727) 823-5642. 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 aid 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 ,
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, may want to also refer to:
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 Programming,
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 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 HEA T (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
SP A 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 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.

General Information:
The Call-Flex option automatically extends or overrides the run time of the water circulator pump,
and heater
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. 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
