Computer fan-coil selection program
To provide optimal fan coil unit selection, McQuay International
provides McQuayTools™ and SelectTools™ for Fan Coil for
computer fan coil selection capability . These computer programs
aid in the selection of the most economical unit size and coil
option to meet the specification. The program capabilities include
hot and chilled water, hot and chilled water with glycol, electric
heat, supplemental steam heat, and unit external static pressure.
To operate the McQuayTools and SelectTools software the user
needs a computer using Windows® 2000 or higher. McQuay will
provide the software to run McQuayTools and SelectTools for
Fan Coil.
Contact your nearest McQuay representative for a copy of

Coils
Standard and optional high capacity cooling coils are available
with manual air vents for all unit sizes. Optional water heating
and steam coils are available for 4-pipe systems. Field installed
automatic air vents are optional for water cooling coils.
Coils are constructed of seamless copper tubes with headers and aluminum fins. Full depth collars, drawn in the fin stock,
provide accurate control of fin spacing and completely cover
the copper tubes to lengthen coil life. Tubes are mechanically
expanded into the fins for a permanent primary to secondary
surface bond, assuring maximum heat transfer efficiency.
The vertical position of the coil assures rapid condensate
drainage to provide even airflow and full rated capacity at all
conditions.
Motors
Tap wound, three-speed, permanent split capacitor motors are
standard for TSH and TSC units. Motors have sleeve bearings
with oilers, inherent thermal overload protection and automatic
reset. Motors are resiliently mounted to assure quiet, vibrationfree operation and are easily removed.
Fan Wheels
All fan wheels are forward curved, double width, double inlet,
centrifugal type and are statically and dynamically balanced
for smooth, quiet operation.
Fan Housings
Split design fan housings allow quick service of fans and
motors.
Fan Deck
Heavy-gauge continuous galvanized steel rigidly supports
motors, fan assembly, and fan housings as a single unit. The
fan deck is self-locking to the basic chassis and is easily removed for service.
Casing and Cabinet
All units are constructed of heavy gauge steel for long life and
durability. TSC units and optional trim flange ceiling frames are
finished with an electrostatically applied, baked-on Antique Ivory
paint.
Single Power Location
All electrical components of the TSH and TSC units are factory
wired to an electric raceway accessible from the bottom of the
unit. All field wiring connections can be made at the electrical
raceway. Electric heaters, depending on amperage, may require more than one field circuit, all of which can be brought to
the raceway.
Speed Controller
A three-speed switch with off position is available for all sizes.
The speed switch must be field mounted in a 2 x 4 x 2
electrical box by others.

Controls Systems
A wide variety of two- and four-pipe control systems are available with wall mounted thermostats or combination thermostat/speed switches (see page 10).
Drain Pans
The galvanized steel drain pan with copper connection is insulated on the external surface with fire rated closed cell foam.
The drain pan extends under the entire coil and coil connections. An optional galvanized steel secondary drain pan provides complete condensate drainage from valve package
components.
Filter
TSC units have as standard a 1" throwaway filter. The filter is
easily removable through the bottom access panel. For TSH
units a filter is supplied only with the optional return
air plenum.
