This fan coil unit provides the flexibility for installation in any
upflow or horizontal application. These versatile models may
be used for split-system cooling or heat pump operation.
Compact cabinets along with return air options in both the
upflow and horizontal positions allow this unit to fit into tight
spaces such as attics, crawl spaces, and closets.
NOTE: For matching condensing units and performance
data, refer to condenser technical guides.

FEATURES
CABINET -The compact and sturdy cabinet is protected with
a durable, attractive finish to prevent rust. The cabinet is also
insulated to prevent cabinet sweating. F*FP and F*FV models have 3/4 inch insulation.
BLOWERS - Blowers are sized to circulate air both quietly
and efficiently. The direct-drive, multi-speed motors provide a
selection of air volume to match any application. Motor
speeds may be selected via quick connect terminal at the
motor. Slide-out blower/motor assemblies provide for easy
servicing.
COILS - Using the latest in heat transfer technology, the rifled
tube coil/aluminum fin coils produce high performance ratings
and provide long lasting quality. The coils are capable of bottom return air in the upflow position, and right or left end
return air in the horizontal position.
FACTORY INSTALLED TXV - Air handler models F*FP and
F*FV have factory installed TXV metering device.
ELECTRIC HEATERS - Models providing up to 25kw of heat
are available as field installed accessories. Electric heaters
are available in both single and three phase.
EASY INSTALLATION - These fan coil units are designed to
provide the lowest total installation cost. Accessible color
coded control wiring, top and side power wiring knockouts,
easy to install drain connections and electric heaters all combine to minimize installed cost on every job.
CONTROL BOARD - The control board is equipped with low
voltage terminal strips for easy installation. The control board
is also equipped with plug-in receptacles for the auxiliary
heaters.

2. Fan only CFM = 63% of high speed cooling.
3. Low speed cooling used only with two stage outdoor units.
(Speed is preset to 65% of high speed).
4. Dehumidification speed is 85% of cooling speed.
5. When operating in both heat pump and electric heat modes, the CFM will
be whichever is greater.
6. CFM indicator light flashes once for every 100 CFM (i.e., 12 Flashes is

Normal
The normal setting provides a 30-second ramp-up from zero
airflow to full capacity and a 30-second ramp-down from full
capacity back to zero airflow. Whenever there is a change in
airflow mode, such as a call for cooling or a change from low
heat to high heat, the motor will take 30 seconds to ramp
from one speed to the other.
Humid
The humid setting is best-suited for installations where the
humidity is frequently very high during cooling season, such
as in the southern part of the country. On a call for cooling,
the blower will ramp up to 50% of full capacity and will stay
there for two minutes, then will ramp up to 82% of full capacity and will stay there for five minutes, and then will ramp up
to full capacity, wh ere it will stay until the wall thermostat is
satisfied. In every case, it will take the motor 30 seconds to
ramp from one speed to another.
Dry
The dry setting is best suited to parts of the country where
excessive humidity is not generally a problem, where the
summer months are usually dry. On a call for cooling the
motor will ramp up to full capacity and will stay there until the
thermostat is satisfied. At the end of the cooling cycle, the
blower will ramp down to 50% of full capacity where it will stay
for 60 seconds. Then it will ramp down to zero. In every case,
it will take the motor 30 seconds to ramp from one speed to
another.
Temperate
The temperate setting is best suited for most of the country,
where neither excessive humidity nor extremely dry conditions are the norm. On a call for cooling, the motor will ramp
up to 63% of full capacity and will stay there for 90 seconds,
then will ramp up to full capacity. At the end of the cooling
cycle, the motor will ramp down to 63% of full capacity and
will stay there for 30 seconds, then will ramp down to zero. In
every case, it will take the motor 30 seconds to ramp from
one speed to another.
