QUICK START & STOP
his 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. If uncertain about any instructions given herein, AquaCal Customer Support (800-786-7751) should
be contacted for additional information.

Start Up
Set pump controls to allow for temporary, continuous operation.
With pump OFF, position water valves to heat the POOL or SPA.
Rotate both thermostats counterclockwise to lowest temperature setting.
Depending on valve settings (per #2, above), position the POOL/OFF/SPA toggle switch to point at
either the POOL or SPA thermostat knob.
5. Ensure power is supplied to the heater, then start the water pump; the POWER and FLOW lights
should now both be lit. Permit the water pump to operate for five (5) minutes before proceeding
How to Operate the Controls - Pool or Spa
1. Turn the selected pool or spa thermostat dial clockwise to its highest setting.
2. The heat pump will start and begin to heat the pool or spa.
NOTE: The heat pump has a time delay so if it shuts down for any reason, it will not
restart for approximately five (5) minutes.
3. The typical spa may take several hours to initially heat up, while a pool may take several days. Heating
time will depend on the volume of water, water temperature, and the climatic conditions at the time of
start-up. (Also see Calculating Initial Heating Time.)
4. When the pool or spa reaches the desired temperature, slowly rotate the thermostat knob
counterclockwise until the heat pump (just) stops. The thermostat is now set to automatically
maintain this temperature.
Time Clock Programming
Once the heat pump has brought the pool or spa up to temperature, it will be necessary to reset the pump
controls. Be sure to allow enough running time for the heat pump to replace lost heat. This time will vary
depending upon the time of year. Colder months require longer running times—usually eight to twelve hours.
Manual Switching From Pool to Spa
NOTE: It is best to stop the pump while repositioning valves.
1. Open spa valves and close pool valves.
2. With the spa filter pump running for at least five minutes, move the POOL/OFF/SPA toggle switch
from the Pool Setting to the Spa Setting.
3. Turn the Spa thermostat clockwise until it stops (104 F).
4. The typical spa may take several hours to initially heat up. Heating time all depends on the volume of
water, water temperature and the climatic conditions at the time of start-up.
5. When the spa reaches the desired temperature (104 F is maximum), slowly rotate the thermostat
knob counterclockwise until the heat pump (just) stops. The spa thermostat is now set to
automatically maintain this temperature any time the spa thermostat has been selected.
To Stop the Heat Pump
The unit can be stopped by switching off the electrical supply or by setting the desired temperature lower
than the actual water temperature.

Refrigerant Circuit Performance Charts
Use of Charts- Information for the Technician:
The charts are intended for use by trained and qualified air-conditioning and refrigeration technicians only.
The charts are compiled specifically for evaluation and diagnostic purposes, and are NOT designed for use
as charging charts. To apply the chart data to actual conditions: gather the operating pressures, suction tube
superheat & liquid line subcooling values, water temperature change through the heater, and the total unit
amps. Locate a chart that most closely represents current actual conditions. Readings obtained that differ
from the charts in excess of 10% (+ or -), may indicate a problem within the mechanical refrigeration
system. Reference: Troubleshooting Refrigerant Circuit Problems, following the charts. Some interpolation
between charts will be necessary should actual conditions not align reasonably well with the charts. Should
refrigerant circuit readings appear normal, but not the Water DT value, the likely cause will be water flow
above or below 45 GPM. (TropiCal refrigerant circuits will perform acceptably with condenser water flow
between 20 to 70 GPM.)

Guide: Troubleshooting Refrigerant Circuit Problems
Refrigerant Circuit Service Only by Qualified, EPA Certified Technician
WARNING !
Failure to heed the following may result in permanent injury or
death.
Heater contains refrigerant under high pressure. Repairs to the refrigerant circuit must not be
attempted by untrained and/or unqualified individuals. Service must be performed only by qualified
HVAC technicians. Recover Refrigerant to relieve pressure before opening system.
NOTE: These guidelines are for use only by experienced, EPA certified, HVAC technicians, and
were developed specifically for use with AquaCal heat pumps, and for use with Refrigerant Circuit
Performance Charts contained earlier in this manual.
Possible Conditions:
Unit Overcharged:
• Head pressure will be above normal;
• Suction pressure will be normal or slightly high (high, only if grossly overcharged);
• Unit amperage will be somewhat high;
• Liquid Sub-Cooling will be higher than normal;
• Superheat will be normal to low (low, only if grossly overcharged).
Explanation: Excess liquid refrigerant backs up in the condenser (into discharge line if grossly
overcharged). Elevated head pressure & high liquid sub-cooling, with near-normal suction pressure and
superheat, will be present. Unless grossly overcharged, the TXV will hold back the overcharge, maintaining
near normal suction pressure and superheat.
Unit Undercharged:
• Head pressure will be below normal;
• Suction pressure will be slightly low, to very low (depending on degree of undercharge);
• Amperage will be low;
• Liquid Sub-Cooling will be very low or nonexistent;
• Superheat will be higher than normal.
Explanation: A full column of liquid may not be consistently present at the TXV inlet. This condition results
in low suction pressure with higher than normal superheat. The liquid sub-cooling will be low, as will be the
head pressure.
TXV Stuck Closed:
• Head pressure will be excessive;
• Suction pressure will be lower than normal;
• Amperage will be high;
• Liquid Sub-Cooling will be higher than normal;
• Superheat will be higher than normal;
• Distributor lines may be frosted, iced, or very cold to touch.
Explanation: The flow of refrigerant is (mostly) stopped at the TXV. This results in a low suction reading
with high superheat. As liquid refrigerant “backs up” in the condenser, there is less room for high-pressure
vapor coming from the compressor. Therefore, head pressure increases above normal (TropiCal models do
not have sufficient space on the high-side to store the entire charge). With little refrigerant flowing, more
heat is being removed in the condenser than is being added at the evaporator- result: higher than normal
liquid sub-cooling.
13
TXV Stuck Open:
• Head pressure will be slightly to moderately low;
• Suction pressure will be slightly high to very high;
• Amperage (not a reliable indicator of this condition);
• Liquid Sub-Cooling will be lower than normal;
• Superheat will be minimal or nonexistent;
• Suction line, and possibly a large portion of compressor, will be very cold and possibly “sweating”.
Explanation: Refrigerant is flowing through the system too quickly; enough heat cannot be added in the
evaporator to boil off all the liquid refrigerant. The main effect is to flood the suction line and compressor
with liquid refrigerant. The primary indicator of this condition is little or no suction line superheat. Also, as
the TXV is not holding back the required amount of refrigerant, there may be flash gas (high-pressure
vapor) present in the liquid line; this is indicated by reduced liquid sub-cooling.
Insufficient Condenser Water Flow:
• Head pressure will moderately high to very high;
• Suction pressure my be normal to slightly high;
• Amperage will be higher than normal;
• Liquid Sub-Cooling will be absent; the liquid line will be very warm or even hot to touch. When combined
with high condenser water DT (see next bullet item), this condition is a prime indicator of insufficient
condenser water flow;
• Condenser entering-leaving water temperature difference (water DT) will be higher than normal… This
condition is a prime indicator of insufficient condenser water flow;
• Superheat will be high-normal to high.
Explanation: Heat is not being removed in the condenser in quantities sufficient to produce appreciable
amounts of liquid refrigerant. With no liquid seal occurring in the condenser, the liquid line–in essence–
becomes an extended discharge line. Keys to diagnosis: very warm to hot liquid line, and a high condenser
water Delta-T.
INSTALLATION
Placement of Heater
Indoor Installation
Every indoor installation is unique, therefore, there are no specific guidelines for this type of installation. For
assistance, please contact AquaCal’s Engineering or Technical department at (800) 786-7751; they will assist
you with your specific needs.
Outdoor Installation
Service and Operational Clearances:
u Refer to recommended clearance drawings following this section. Allow 24" clearance between the heat
collection surfaces and walls, fences, shrubs, or other objects. The heat pump requires large volumes of air
moving over the heat collector.
u Allow 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 evaporator
coils (recirculation would reduce the overall performance of the heat Pump).
u Provide at least 30” open area in front of the main access panel. The electrical panel will need to
be accessed during installation and service, so avoid any plumbing obstructions that will restrict
easy access.
14
Code Required Clearances:
u 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 rain runoff from the roof. A gutter or rain shield may 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 plant shrubs or
bushes directly adjacent to heat pumps. Doing so will prevent proper air circulation into the unit, and may inhibit
access to the heater when service is needed. Consult drawings above for proper clearances.
Equipment Pad Requirements
The equipment pad should be constructed to provide adequate drainage and support to the base of the heat
pump (see Table below). The pad should be essentially level with just enough pitch to drain condensate and
any other water away from the heater.

Anchoring Heater to Pad
Follow all relevant local, state, or national requirements regarding wind load anchoring (use huricane anchoring
kit, part #STK0010). As necessary, contact AquaCal Technical Support, 800-786-7751, for assistance in
determining best method of compliance.
15
Plumbing Requirements
Overview:
When planning plumbing system layout, reference the plumbing schematics following this section as a guide to the
sequence of equipment, valves, fittings, etc. The plumbing configurations for typical installations are diagrammed.
In operation, it is imperative the heat pump receive water flow within the minimum-maximum ranges specified for
the particular heat pump. Should the system installation under consideration not closely match any of the schematics,
contact AquaCal Technical Support for advice and guidance: (800) 786-7751.
Parts and Materials:
Industry technology changes much too rapidly for AquaCal to specify, with exactness, any items outside and
beyond the heat pump. What is specified is that the heat pump must be installed in accordance with all applicable
local, state, or national codes & standards.
Connection to Heat Pump:
All TropiCal heat pumps come equipped with 2" PVC, plumbing unions. Connection to site plumbing is made via
PVC solvent cement to the female slip socket of the plumbing unions.
Ability to Winterize:
In regions where hard winters are typical, the unions mentioned above allow for easy disconnection/reconnecting
of the heater from the plumbing system. Caution: do not defeat the function of the unions–use no glue on the
threaded portion of the unions.
Maximum Operating Pressure: 50 PSI
Minimum/Maximum Water Flow Rates:
All TropiCal models are designed to operate successfully between flow rates of 20 to 70 gallons-per-minute
(GPM) . Design the plumbing system to maintain at least 20 GPM flow through the heater; the heat pump will not
operate correctly, nor reliably, with less than 20 GPM of water flow supplied. If water flow rates through the
heater will exceed 70 GPM, a spring-check bypass valve will be required; generally speaking, most residential
pools and spas will not require a bypass unless a pump of 2 HP or larger is used (for bypass valve details, see
information and plumbing schematic, following).
External Bypass Check Valve Requirement
For installations where flow rates exceed 70 gpm an additional spring bypass check valve must be installed.
NOTE:
Use of the wrong size check valve may compromise the heat pump’s efficiency, reliability, and may
void the factory warranty. For models T135, T115 & T65, a 5 lb. Spring check valve is required.
(AquaCal Part #2556.)

Water IN & OUT Connections
For proper operation and maximum efficiency, piping coming from the pump and filter MUST be connected to the
"IN" port of the heater. Likewise, connect piping returning to the pool/spa to the "OUT" port of the heater. See
drawing below.
Electrical Requirements
WARNING!
Failure to heed the following may result in permanent injury
or death.
Installation made by unqualified persons can result in hazards to the installer and others. The information
contained in this Electrical Installation section is intended for use by qualified electrical installation technicians,
familiar with electrical service industry safety standards and methods. Electrical installation to be performed
by qualified individuals only.
General Information:
u When possible, locate the equipment disconnect means within arm's reach of the heater's
electrical enclosure or as close as possible to the heater. Always satisfy applicable codes and
standards.
u All AquaCal heat pumps are designed for copper conductors, only. In sizing power wiring, be
especially aware of up-sizing requirements required due to wiring distances. Always satisfy
applicable codes and standards.
u Multiple heaters installed at same site generally require special sequencing controls (AquaCal part
#ASC-(number of heaters)); if yours is a multi-heater installation, contact AquaCal Technical Support
for assistance (800-786-7751).
u Electrical installation should be by licensed electrician only.
u Connecting External Controllers: See document entitled “Connecting External Controllers to
AquaCal Heat Pumps”. These instructions are shipped inside heater accompanying the electrical
schematic.
18

Overview of Controls
(Please refer to control panel diagram on previous page.)
POOL/OFF/SPA Toggle Switch:
With the toggle switch in the OFF (O) position, the heater will be prevented from operating (however, there may
be power to the unit; see "Power Light On", below). With the toggle switch positioned toward the SPA or POOL
thermostat knob, and with the following conditions met: 1) water pump in operation, 2) water flowing through
the heater, and, 3) electrical power to the heater, the heater will run anytime the water temperature drops below
the thermostat setting.
Note-Heater Can Start with Thermostats Set to Minimum:
With proper water flow and electrical power supplied to the heater, and either the POOL
or SPA thermostat selected and set to minimum, the heater will run any time the water
temperature falls below 60º F. To prevent the heater from operating at water temperatures
below 60º F, position the POOL/OFF/SPA toggle switch to the middle, OFF position.
Power Light On:
Indicates electrical power is supplied to the heater. The heat pump will start if the selected
(POOL or SPA) thermostat calls for heat, and there is proper water flow through the heater.
Power Light Off:
Indicates proper electrical power is not getting to the heater. If attempting to operate the heater,
ensure any disconnect switches, or circuit breakers, are switched to the ON position.
Flow Light On:
Indicates sufficient water flow to permit the heat pump to operate. The heat pump will start
upon a call for heat from the selected POOL or SPA thermostat.
Initial Start-Up and Basic Operation
(Please refer to "Overview of Controls", above, before continuing.)
1. Lower Thermostat Settings-Set P/O/S Toggle Switch to OFF:
u Turn both thermostat knobs counterclockwise to lowest settings.
u Position the POOL/OFF/SPA toggle switch to "OFF".
2. Establish Water Flow and Electrical Power to the Heat Pump:
u Position the water valves to heat either the pool or the spa.
u Ensure any heat pump-related disconnect switches, or circuit breakers, are switched to the ON
position.
u Start the pool or spa pump (depending of which body of water is to be heated), permitting the
pump to operate for a few minutes before going on to next step. This wait is necessary to clear
any air that may exist in the water piping.
u The heat pump will not start without water flowing through it. At this point, the power and flow lights
should be illuminated.
3. Select POOL or SPA-Raise Associated Thermostat:
u Position the POOL/OFF/SPA toggle towards the POOL or SPA thermostat knob (depending
on which body of water you are preparing to heat).
u Turn the selected pool or spa thermostat dial clockwise to its highest setting. As soon as the
thermostat setting is above the temperature of the water, the heat pump will begin to operate.
21
Note-Five (5) Minute Time Delay Function:
The heater controls contain a solid-state time delay module. This time delay feature prevents
damage to the compressor should electrical power be repeatedly interrupted, or if the heat
pump were to come under any other circumstances leading to an on-off-on-off cycling condition. If the heater has water flow and electrical power supplied, but the heater does not immediately start upon turning the thermostat to its highest setting, wait five (5) minutes; the time
delay module may be preventing the heater from operating. Likewise, once the heater is
running, if the thermostat is turned back below the present water temperature, the heat pump
will shut off. Subsequently, the heater cannot restart for approximately five (5) minutes, no
matter how far the thermostat is turned back up.
4. Ensure Uninterrupted Pump Operation During Initial Warm-Up:
u Permit your pool or spa circulation pump to run continuously until the desired water temperature is
reached. (with a pool, this may take several days.)
u Continuous pump operation will likely require temporarily resetting (or removing completely)
the trippers on the time clock, thus allowing nonstop operation. When an external electronic
controller operates pumps and valves, follow the controller manufacturer's instructions to
ensure temporary, uninterrupted pump operation.
u Throughout the warm-up period, keep the selected pool or spa thermostat dial set clockwise
to its highest setting.
5. Desired Water Temp. Reached-Set Thermostat to Maintain:
u Once the desired water temperature has been achieved, rotate the thermostat knob very slowly
counterclockwise until the unit (just) shuts off.
u The heater will automatically maintain your pool or spa at the selected temperature.
6. Return Pump Timer Controls to Normal Settings:
u Reset pump timer controls for normal daily hours of operation.
u During cooler or cold weather conditions, it may become necessary to extend the daily hours
of pump operation; doing so will help the heater to keep up with increased heat losses.
u Also see next topic: "Heating Tips”
Heating Tips
Pool/Spa Blankets
A solar blanket will significantly reduce your heating bills. You should check with the installing dealer to see if
your heat pump was sized to be used in conjunction with a solar blanket or without one. 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 solar blankets.
WARNING !
Failure to heed the following may result in permanent injury or
death.
Improperly used, Pool-Spa solar blankets can become a drowning risk to people and pets. Solar blankets
are not safety covers. They are not designed to support the weight of a person or pet. Never enter a
pool until the solar cover is completely removed (under no circumstances should anyone swim under the
blanket). Follow all safety recommendations of the blanket manufacturer.
22
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.
TropiCal model heat pumps come 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 AquaCal Universal Heater Control (AquaCal
part #0097TS). This will save you from having to change the thermostat switch each time you change from pool
to spa and back again. For details, contact your installing dealer.
Spa Heating
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 POOL thermostat can bet used as a set-back control: 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 set-back method. This method will result in
reduced warm up periods over full-cold start ups.
Heating in Cooler Weather (Defrost Cycle)
When air temperatures drop below 50º F, your heat pump may go into a defrost cycle. The defrost cycle is
initiated by a sensor on the evaporator (air coil). When the evaporator temperatures fall to a point where ice
begins to form on the fins, the heat pump will shut down. The heat pump will remain in the defrost mode until the
evaporator coil temperature rises. In the event the air temperatures are below 40º F, the heat pump will remain
in the defrost mode until temperatures rise above the 40º mark. The length of time the heat pump is in the defrost
mode is dependent upon the air temperature: the warmer the air temperature, the shorter the defrost cycle; the
colder the air temperature, the longer the defrost cycle.
The need to defrost, is a very good reason why you should operate your heat pump only during the warmest part
of the day. Late night and early morning is usually the coolest time of the day, and least efficient for heat pump
operation.
Calculating Initial Heating Time
The initial time it takes to get your pool warm depends on several factors. First you will need to determine how
many gallons of water are in your pool. If you know this, you can compute the pounds of water in the pool and
the BTU's necessary to heat the pool to the desired temperature. Secondly, you need to know the approximate
BTU output of your heat pump at the ambient air temperature. Finally, you will need to determine the temperature at which you plan to maintain your pool or spa.
Sounds complicated, but it's not! You can use the following worksheet to calculate approximately how long it will
take your heater to bring your pool up to temperature. Keep in mind that the time will vary somewhat due to
weather conditions during the period that the heater is in use.
23
Volume of Pool (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) ___________4 BTU Output of Heater = ______ Hrs. of Operation
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.
When you start up your new AquaCal Heat Pump for the first time to heat your pool, you must allow the unit to
run continuously until the desired temperature is reached. This may take from several hours to several days
depending upon the time of the year and the outside conditions. If you utilize a time clock or similar device to
control the operating time of your pool system, you should temporarily override the device and allow it to run the
pool or spa pump until the water reaches the desired temperature.
Your heat pump is a maintainer of heat and is sized to overcome the heat loss during the coldest period in which
you are trying to heat. Once your pool is up to temperature, the time clock can be reset. The time your system
has to run may need to be extended during the colder months when heat loss is at its greatest.
Since air is generally at its warmest during the day time, it is best to operate your heat pump during the daytime
when there is more heat to transfer. So keep this in mind when you are trying to heat your pool.
NOTE: An optional Call Flex time clock manager (AquaCal part #0030S) can free you from having to
change the settings on your time clock as the heat loss increases or decreases. Contact your installing
dealer for details.

General Maintenance
u You should have your heat pump inspected and maintained on an annual basis by a qualified pool
heat pump specialist. Additionally, if your heat pump is located on the beach, or at a sea wall where
salt spray and sand can affect the unit, more frequent service may be necessary. For Service Plan
information, please see: Planned Maintenance Program, above, and then contact AquaCal Customer
Support at: 800-786-7751.
u While annual maintenance is recommended to maintain your warranty, if you choose not to
participate in the Planned Maintenance Program, rinsing the air coil regularly, and keeping the base
of the unit clear of leaves and debris is a must.
25
WARNING !
Failure to heed the following may result in permanent injury or
death.
POSSIBLE ELECTRIC SHOCK HAZARD . . . Should you decide to wash the unit via water hose,
disconnect all power to the pool equipment pad- including, but not limited to: The heat pump, water pump,
and any and all other electrical equipment. Do NOT sprag water directly into electrical components. Do
NOT restore electrical power until such time as all water has dried completely.
CAUTION !
Failure to heed the following may result in damage to equipment.
Do not use a pressure cleaner to wash heat pump . . . . Damage to evaporator fins, as well as other
components, will result.
u Control Irrigation: In regions were wells are used for irrigation, water quality is sometimes less than
poor, and water spray can damage heater components. Regardless of water quality, it is
recommended that sprinklers be directed away from the heat pump.
u Prevent rain water run-off, from roofs, 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.
u Drainage: Your heat pump may produce abundant condensation under certain conditions; this is
considered normal operation. Accordingly, keep the drain holes at the base of the heat pump free
of grass, weeds, dirt, or other obstructions, allowing for free and complete drainage around the
heater.
u If the heat pump is located under trees, where leaves fall and accumulate in the bottom of the heat
pump, a qualified technician should periodically remove accumulated leaves.
Maintaining Proper Water Flow
u 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.
u Similar to a dirty filter, large amounts of debris in the pump basket can reduce water flow. Keep
basket free of debris.
u 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 the heater.
u If the conditions listed above remain unresolved, the water flow through the heater may be reduced to a
point where internal safety devices shut the heater off. Before calling for service, always check the filter,
the pump basket, and water valve positions. If the problem persists, call AquaCal Customer Support
at: (800) 786-7751.
NOTE: During pool refinishing or acid washing, the water flow through the pool heater must be shut off
until the process is completed, and the pool chemistry is once again in balance.
26
Maintaining Proper Clearances Around Heater
u For maximum efficiency, proper air flow clearances around heater must be maintained.
u It is important to keep the area around your heat pump clear of items such as shrubs and bushes, lawn
furniture, chemicals containers, etc. These items can prevent air from circulating properly through the
heater, and will result in inefficient operation or damage to components inside the heat pump. 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.
u 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.
u Please see: Installation, Service, and Operational Clearances, for specific spacing requirements.
SEASONAL USE & SHUT DOWN
During the Swim Season
u During the swim season, even if the pool or spa is not in use, allow water to flow through the heater.
u This eliminates the need to reposition valves when you do wish to heat your pool or spa.
Freeze protection / Extended shut downs
u In areas where freezing conditions are a rare occurrence, allow the filtration system to run continuously
through the freeze period. Typically, during light freeze conditions, circulating water
will not freeze.
u In areas where freezing conditions are prevalent, please refer to winterizing instructions following this
section.
Winterizing (Hard Freeze Conditions)
CAUTION !
Failure to heed the following may result in damage to equipment
and/or property.
Failure to properly winterize unit may result in freeze damage to the heat pump. Freeze damage is not
covered under the unit warranty.
CAUTION !
Failure to heed the following can result in damage to equipment
and/or property.
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.
27
Winterizing Procedure:
1. Disconnect all electrical power to the heater; turn OFF circulating pump.
2. At the two (2) water connection unions, disconnect the plumbing to the heater (removal is
counterclockwise).
3. Locate the drain plug at lower, right-hand, front corner of heater. (See Figures 1 & 2, below.)
4. Using a 5/8", box-end wrench, remove the drain plug (removal is counterclockwise).
5. 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.
6. 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.
7. Next Season: to ready the heat pump for use, simply retighten plumbing connection unions.
Hand-tight is generally sufficient.

TROUBLESHOOTING
Common Troubleshooting Issues
Heat Pump Not Running
Is the power light lit?
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 flow light lit?
If not , 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, and have you tried turning the selected thermostat to 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 unit should start after an
approximate 5-minute delay. If the heat pump still fails to start, and the unit is not in defrost (defrost
light lit), contact AquaCal Customer Support: 800-786-7751.
Heat Pump Running but Not Heating
Is the air blowing out of the top of the unit noticeably cooler than the surrounding air?
(A 9°F to 12°F difference is typical.) If not, call AquaCal for service at 800-786-7751.
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 long are you running your circulating pump each day?
Cooler weather conditions, or heating to a higher temperature, may necessitate running the heat
pump for a longer period of time. A pool blanket can be useful in permitting shorter run times,
in turn leading to substantial energy cost savings.
What is the air temperature?
Your heat pump may be in the defrost mode if air temperatures are below 50°F. The defrost
light will be lit if the unit is defrosting. If air temperatures are not cold, but the defrost light is
still illuminated, 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 off your heat pump, leaving the pool pump running. In a couple of hours there should be a
marked reduction in the amount of water around the bottom of the heat pump. If the water appears
to be drying up, the water is probably harmless condensate.
Or, as an alternate method to check for a water leak, you can test the water draining out the
base for the presence of the sanitizer you are using in your pool or spa. Use your water test kit,
or a test strip, to 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: If you are using an ionizer or ozone generator to produce sanitizer, this test method will not be
effective.
