WATER HEAT EXCHANGER
The compressed hot gas releases its heat to the
pool water inside the heat exchanger. The ex-
changer is a tube within a tube construction, wa-
ter passing through the inner tube, and the hot
refrigerant passing through the outer tube. The
refrigerant is transformed into a liquid (con-
densed) state as it releases it's heat to the pool water. There-
fore, it is also referred to as a condenser coil. The alloy
exchanger is designed for maximum transfer surface area and
strength.

WATER PRESSURE SWITCH
When water starts flowing through the unit the
water pressure switch will activate and allow
the unit to run. When the circulation pump
timer stops the water flow, the wa-
ter pressure switch will shut the unit
off. When the pump restarts for the
next day, the pressure switch will
activate and allow the heater to run
again.

WATER FLOW & EXISTING WATER PUMP
To filter the pool water each day, the water pump will come
on & off according to the existing timer device. The heater
will only heat if there is water running through it and it op-
erates long enough.
Turning up the thermostat will start the unit.
When the pool water has been heated to the
thermostat setting, the unit will shut off. When
the pool water temperature loses one to two
degrees, the thermostat will activate the unit.
There are no temperature graduate numbers
printed on the thermostat face. To obtain an
exact temperature for a pool, turn the
t-stat 3/4's of the way up and then place a pool
type thermometer in the pool water itself. Once
the water has reached your target temperature
on the thermometer, turn the thermostat knob
backwards until the heater just shuts off. There-
fore your thermostat will be set at the thermom-
eter reading.
THERMOSTAT CONTROL & SETTINGS
FAN-AIR CIRCULATION
Once the t-stat is activated the fan will begin to turn. To
collect the heat from the air, the fan circulates warmer air
through the evaporator air coil at about 4200 cubic feet per
minute. The fan runs independently from the compressor.
The compressor will start within 5 to 7 minutes after the fan.

COMPRESSOR
Once the fan is running, the compressor will start
5 to 7 minutes later and is controlled by a time
delay device. The compressor pumps and com-
presses refrigerant gas. When gas is compressed
it gets very hot and intensifies the energy and
then is released to the pool water. This com-
pressed hot gas is pumped through the heat ex-
changer where it delivers heat to the pool water
passing through the same heat exchanger.
EVAPORATOR AIR COIL
The fan circulates the warmer outside air
through the evaporator air coil to collect any
available heat. The cooler refrigerant ab-
sorbs this heat. This evaporates the refriger-
ant into a gas. Therefore the compressor can
compress the gas to maximize the gained heat
from the air.

THERMOSTAT CONTROL & SETTINGS
FOR HEAT & COOL MODELS
For heating mode on these models, make sure
toggle is selected to heat and follow the pre-
vious instructions above. For cooling mode,
make sure toggle is selected to cool. Turning
down the thermostat counter clockwise will
start the unit running. When the pool water
has been cooled to the thermostat setting, the unit will shut
off. When the pool water temperature rises one to two de-
grees, the thermostat will activate the unit. There are no
temperature graduate numbers printed on the thermostat
face. To obtain an exact temperature, turn the t-stat all the
way down and then place a pool type thermometer in the
pool water itself. Once the water has reached your target
temperature on the thermometer, turn the thermostat knob
forwards until the heater just shuts off. Therefore your
thermostat will be set at the thermometer reading.
