HEAT PUMP OPTIONS
ThermoLink
®
Heat Exchanger (AT110 Model only)
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.
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 like-new appearance with only an occasional wash down and—if so desired—a
quick waxing.

TROUBLESHOOTING
(Also see page 5 for Program Codes)
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, have you tried selecting a higher temperature setting, and have you
chosen the correct “Mode” of operation?
If not, the actual water temperature may be above that of the selected thermo-
stat. Raise the desired water temperature above the actual water temperature;
the fan should start, and after approximately four (4) minutes, the “Heating”
light should illuminate. If the heat pump still fails to start, and the unit is not
in defrost (heat-only unit defrost display code is: “FS”), contact Aquatherm

Heat Pump Running... but is it Heating?
Is the air blowing out of the top of the unit noticeably cooler than the
surrounding air?
(With heating indicator light illuminated, a 9°F to 12°F difference is typical.)
If not, contact Aquatherm for service at: 239-482-0606. 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 lead-
ing to substantial energy cost savings.
What is the outside air temperature?
The heat pump may be in the defrost mode if air temperatures are below 50°F.
With Heat-Only models, if the heater is in defrost, the code: ”FS” will be
displayed. If air temperatures are not cold, but the heater remains in defrost,
contact Aquatherm at 239-482-0606.
