FILTERPUMPOPERATION
NOTE: Some systems utilize a timer to control filter pump run
time. If a timer is present, follow instructions below:
TOSTOPTHEHEATER
Select: OFF via the MODE selector. This method of shut down
preserves the controller settings; an interruption of water flow–
such as when a pump timer is in control–will also stop heat
pumpoperation.
1. Verify Electrical Power is Present at Heater:
3. To Begin Heating:
–
GETTING STARTED
–
These instructions are intended for local control of a
heat pump, independent of an external controller.
OWNERS: if your installation includes an external controller, con-
tact your installing dealer, and/or the controller manufacturer, for
operational instructions.
2. Set the Heater Controls:
A. Make certain the heater has electrical power connected; the
controllerdisplayshouldbeilluminated.
B. If the display is blank, be certain the electrical breaker, and
heater disconnect, are switched to ON.
C. For now, leavethewatercirculationpumpOFF.
OWNER- If heater is connected to a Call-Flex controller, also
see: “Call-Flex Programming,” located within the “Owner Level
Programming”sectionoftheheatermanual.
INSTALLER-Is heater connectedtoan external controller?Ifso,
setupprogrammingisnecessary.See:“ControlsConfiguration,”
located within the “Level-2 Programming” section of the heater
manual.
(Setting SPA, continued) An illuminated SPAindicator light,
located on the left side of the display, will confirm the SPA
control has been selected. Use the UP / DOWN arrow keys
to set the desired water temperature for the SPA. If heating
only a POOL, using the DOWN arrow key, lower the SPA
temperature until OFF is displayed.
The heat pump controls are now set to maintain the desired
watertemperatureforthePOOLand/or SPA.

daily run time. This will enable the heater to keep up with in-
creased heat losses.
The filter pump will need to run continuously until the water

NORMALUSAGE
Aftertheheatpumphas been running forsometime,watermay
be seen around the unit. This is condensation produced as a
normalby-productoftransferringheatfrom the air to the poolor
spa.Quantitiesof6-8gallons per hour arenotuncommonwhen
the humidity is high. Water from heater seems excessive? See
“Water Coming From Heat Pump” later in this guide.
VERY IMPORTANT NOTE!! Waterchemistry…Yourheat pump
hasbeenengineeredfordurabilityandreliability;however,pro-
longed exposure to unbalanced water chemistry will result in
prematurefailureandservice requirements.
Keep chlorine in the 1-3 PPM range- If bromine is being used,
2.0 to 4.0 PPM.; pH between 7.4 and 7.6; Alkalinity, 80-100
PPM;hardness125PPM (or more).Exactneedswilldepend on
the type of pool surface; check with your pool service expert.

MAINTENANCE &WINTERIZING
Your heat pump should be serviced annually by aqualifiedpool
heatpumpspecialist.Ifyourheatpumpislocatedonthebeach
or a sea wall, where salt spray and sand gets in or on the unit,
morefrequentmaintenancewillbenecessary.ContactCustomer
Supportfordetails (727-823-5642).
Provideproperairflowtothe heat pump. Keepthesidesandtop
oftheheatpumpfreeofobstructions.
ControlIrrigation:wherewells areusedforirrigation,water qual-
ity can be poor. Heat pump components can be damaged by
wellwater;regardlessofwaterquality, itisrecommendedsprin-
klers be directed away from the heat pump.
Drainage...aspreviouslystated,your heat pump,undervarious
conditions, will produce large quantities of condensation. Keep
the drain holes, located at the base of the heat pump, free of
grassandweeds.
If your heater is located under trees, leaves may fall and accu-
mulatein thebottomoftheheatpump.Accumulateddebrisshould
beremovedbyaqualified technician.
VERY IMPORTANT NOTE!! In areas where hard freeze condi-
tions occur, proper winterizing of the heat pump is critical. For
detailed instructions on winterizing, refer to “Winterizing” in the
heatermanualoratwww.aquacal.com.
Inareaswherelightfreezingconditionsoccur–lastinglessthan
four(4)hours–keep thewaterpump operating.Flowingwater will
not freeze under limited, light freeze conditions.

HeatPumpRunningbutisitHeating?
Isthedisplayilluminated?Ifnot,checktoseeif the main break-
er (located at the power supply panel) has tripped, or if the unit
disconnect switch (located near the heat pump) is off. Reset
breakers and switches to ON. In order to begin operation, the
heater’s control display must be illuminated.
Does the display read “FLO”? If so, check to be sure the circu-
latingpumpisoperatingandthewaterfilter is clean. There may
also be a valve positioned incorrectly allowing water to bypass
the heat pump.
Does the display read “OFF”? If so, depress the MODE button
until“HEA”displays.If still “OFF,” thedesiredwatertemperature
is set below 45°F. Raise the desired water temperature above
the actual water temperature; the heater should start within 3-4
minutes.

Be sure all air coil surfaces are free from obstructions; low roof
overhangs,landscaping,walls,fences,etc.canrestrictairflow.
The heat pump needs unrestricted airflow to operate at peak
efficiency.
Howlongareyourunning the water circulatingpumpeachday?
Cooler climatic conditions, or heating to a higher than typical
temperature,maynecessitaterunning the heat pumpforalong-
er period of time.Apool blanket may be necessary to allow for
shorter run times...not to mention significant heating cost sav-
ings.
What is the air temperature? Your heat pump may be in the
defrostmodeifairtemperatures are much below50°F.The digi-
tal display will read “FS” if the unit is defrosting or air tempera-
turesaretocoldfornormalheatpumpoperation.
Istheairblowingout of the topoftheheaternoticeably cooler (9
to 12° is typical) than the surrounding air? If not (after having
checked the three items above), call Customer Support: 727-

Shuttheheatpump off, leavingthepoolpump running. Inacou-
ple of hours, there should be a marked reduction in the amount
of water seen around the bottom of the heat pump.
Ifyoubelievethe heat pump isleaking,checkthe water draining
from the heater for the presence of the sanitizer being used in
the pool or spa. Using your chemical test kit, check a sample of
the water for chlorine or bromine. If the sample tests positive,
callforservice at: 727-823-5642.Ifthe test isnegative,the water
is probably harmless condensate. If using an ionizer or ozone
generator as a sanitizing means, the chemical test method will
notbeeffectiveindeterminingwaterleaks.
CAUTION !!! If testing indicates a water leak is present (water
does not dry up with the pump OFF, or there is an indicationof
sanitizer in the sample taken from around the heater), immedi-
ately shut off the water pump and contact your installing dealer
orCustomerSupportforservice.Permitting the system to oper-
ate with a water leak present may damage equipment and the
pool/spastructure
