PRO Split System Fan Coil Unit
The PRO Split System fan coil unit meets its rated capacities for total BTU/H and CFM at design room
conditions and external static pressures. The fan coil unit is capable of rated CFM against the static
pressure imposed by recommended ductwork. The fan is a motorized impeller type, statically and
dynamically balanced, and uses permanently lubricated direct drive motors requiring no maintenance.
The PRO Split System fan coil section operates as air passes through the cooling coil and is cooled by
the refrigerant inside the coil. This causes any excess humidity in the air to condense and be captured
in the drain pan and piped outside the unit. Air then enters the fan where it is pressurized and
discharged out of the unit through one of five openings. Optional heating coils are located between the
cooling coil and the fan. These coils heat the air to prevent low temperatures in the wine room.
All exterior framing of the PRO Split System is powder coated 0.063 inch gauge aluminum to prevent
rust and corrosion. All coils are aluminum tubes, aluminum fins to protect against premature corrosion.
The unit uses an external drain to remove excess moisture and not reintroduce it into the room or
ambient space. Removable, multiple access doors are provided to facilitate cleaning and maintenance,
duct connections, and access to components and wiring. The fan coil has at least five discharge outlets
to facilitate custom installations.
Each unit is provided with a 24 volt terminal strip for connection to most standard 24 volt thermostats
or humidistats. A thermostat is not provided as standard equipment.
Electrical Controls
The main electrical control components are located on a separate panel accessible through a side door panel or by
removal of the on/off panel from the system chassis. All wiring is in accordance with the NEC. Wires are
numbered and color coded to match the wiring diagrams.
Electric power is supplied by a single factory-furnished cord and plug.
Condensing Unit
Compressors are rotary, self-lubricating, permanently sealed, hermetic reciprocating-type compressors,
with internal overload protection and capacitor start. They include a minimum of 20 months
manufacturer's warranty and an optional five-year warranty. Compressors are mounted on rubber-in-
shear isolators to reduce noise and vibration. Additional features include a liquid line filter drier, Head
Master Controls, a liquid line receiver, refrigerant sight glass, manual reset high pressure switch and
auto reset low pressure switch. Each unit is housed in a painted aluminum enclosure suitable for
outdoor installation. The outdoor enclosure has an integral fan for air movement across the condenser
coil, pre-drilled penetrations for electrical connections and external king valves for ease of refrigerant
piping connections.
IMPORTANT
The air exhaust from the condensing unit is hot and will be 25 to 35 degrees F above the entering
temperature. The condensing units are rated for a maximum temperature of 115 degrees F. The
condensing units should be installed in a well-ventilated area to ensure proper air flow across the
condenser coil and to limit short cycling.
