The 42BHC, BVC belt drive
fan coil units provide year-
round comfort air
conditioning with central
station operating economy.
42BHC UNIT
A variety of coil options
reduces first cost
Four, 6 or 8-row cooling coils combine
needed capacities with the most effi-
cient heat transfer surface. For
4-pipe systems, select either of two
split-coil options. Coils consist of alu-
minum fins securely bonded to 1/2-in.
OD seamless copper tubes. Each fin’s
aluminum collar ensures accurate con-
trol of the fin spacing, while complete-
ly covering the tubes to lengthen coil
life. All coils also feature manual air
vents, with automatic air vent available
as an option.

†Field-installed accessory.
Heater coils are constructed of high-grade resistance
wire that is supported by ceramic insulators on plated steel
brackets. These heat elements are suspended directly in
front of the outlet after the blower and the coil. High limit
thermal cutouts protect the heater in the event of air
failure.
Filters — Two in. pleated filters are standard. One-in.
pleated, two 1-in. throwaway, or 2-in. MERV (minimum
efficiency reporting value) 11 filters with 2-in. pleated
pre-filter are available. The 2-in. MERV 11 filters with 2-in.
pleated pre-filter include a filter rack.
The 42BHC and 42BVC fan coil units are designed to
offer maximum flexibility in an application, accessibility for
service, quiet operation and durability.
Factory-installed options
Automatic air vents — Automatic air vents have fiber-
washers, which allow air in the pipes to pass through,
automatically bleeding the system. The fiber washers elimi-
nate the need to manually remove air from the system.
When wet, washers swell and seal the system.
Insulation — Tuf-Skin™ II (1-in. thick) insulation is
standard. Units are available with ¾-in. closed cell, 1-in.
Tuf-Skin Rx™ edge sealed, or 1-in. foil-faced insulation.
Coils — Coils are available in a choice of two-pipe system
with 4-row cooling/heating or four-pipe system with 4, 6
or 8-row cooling and 1 or 2 row heating.
Motors — A wide selection of standard motors provides
efficient operation in ducted applications with excellent
performance with up to 2 inches of total static pressure.
Reheat operation is standard. Preheat is available as an
option.

a 84 in. long (for sizes 20-40) rod for field installation of an
actuator.
• Motor control contactor
• 24 v condensate overflow switch
Electric heat — Total electric heat eliminates the require-
ment for a boiler. Heating and/or cooling may be available
on an individual basis throughout the year. Resistance

TOTAL WEIGHT UNIT CORRECTION FACTOR (lb)
Corner weights on pages 12 and 13 are for 8-row water filled coils. For a different number of rows, total unit weight
can be determined by the following procedure:
• Identify the number of rows and the size of the unit.
• Determine the total weight of the unit from the Corner Weight tables.
• From the table below, identify the correction factor (for size of unit and number of rows) and subtract this from the
total weight.

with water, completely sealing the valve. As air
accumulates, the fiber discs dry and shrink, repeat-
ing the cycle. Not recommended for removing large
quantities of air encountered during initial start-up
or subsequent draining and refilling. Should not be

Selection procedure
This selection procedure provides a guide to determine
unit performance of the 42BHC, BVC units. Capacity
tables (in Performance Data) are based on nominal cfm.
Correction factors are provided for other operating condi-
tions as explained in the following selection example.
For applications outside the range provided in this
catalog, please consult the factory.
FORMULAS:
TC = TCb x Ct x Et
SC = SCb x Cs x Es
Where:
Cs = Sensible Airflow Correction Factor
Ct = Total Airflow Correction Factor
Es = Sensible Elevation Correction Factor
Et = Total Elevation Correction Factor
SC = Sensible Capacity
SC = SCb x Cs x Es
= 34.2 x .96 x 1.00
= 32.83 MBtuh
a) Calculate water pressure drop (or refer to the Water
Pressure Drop for Cv Factor and Water Flow Rate
table on page 33). From the Cv Factor by Coil and
Unit Size table on page 32, find the Cv value for
unit size 16 with four rows.
Cv = 7.2
P = [GPM/(0.658 x Cv)]2
= [7.0/(0.658 x 7.2)]2
= 2.18 feet of H2O
b) For selections other than those listed here, please
contact the factory.
IV Determine motor.
To determine motor and drive selection requirements
and obtain the cfm for a specific application, the
total static pressure (TSP) for that application must be
determined.
The TSP is the sum of the internal static pressure
(ISP) and the external static pressure (ESP) measured in
inches of water column. Internal static pressure is the
sum of the static resistance of the unit’s components
— the cabinet, coil and filter. The ESP is the static
resistance of the unit’s external components, including,
but not limited to, ductwork, grilles and additional
filtration. For non-ducted applications, the ESP is
0 in. wg.
After the TSP has been calculated (see the following
example), use the motor horsepower table on pages 30
and 31 to determine actual horsepower (hp) for the belt
drive unit. Horsepower offerings are limited to 1/4, 1/3,
1/2, 3/4, 1, 11/2, 2, 3 and 5.
The standard selection is the nearest offering above
the actual hp shown in the table.
SCb = Base Sensible Capacity from Base Cooling Capaci-
ties by gpm charts
TC = Total Capacity
TCb = Base Total Capacity from Base Cooling Capacities
by gpm charts
EXAMPLE:
I Rate unit performance.
To rate the performance at sea level for a 42BHC16
unit with a four-row coil at 80 F/67 F EAT, 45 F EWT,
7 gpm water flow, and 1500 cfm:
a) Enter the Base Cooling Capacities by Gpm, 4-Row
Capacity Units table at 80 F/67 F EAT and
45 F EWT.
b) Locate the appropriate row for unit size 16 and
7 gpm.
Record the tabulated base performance.
TCb = 42.0 MBtuh
SCb = 34.2 MBtuh
Using the TSP of the table, match the unit size with
the cfm row to determine the correct motor for the
specific application. Drive sheaves and the required
belt assembly will be provided to meet specific design
requirements. Drive sheaves are set at the factory.
Calculate the hp and drive selection required to deliv-
er 1500 cfm on a 42BHC16 unit equipped with a
4-row hydronic cooling coil and a 2-in. pleated filter in
a ducted application at .38 in. ESP, including duct and
grille losses.
∆T = 12.0 F
c) Divide CFM Actual by CFM Nominal to determine
Cfm Ratio.
Cfm Ratio = 1500/1600 =.9375
II Select CFM correction factors.
Select the Cfm correction factors, Ct and Cs, from the
Airflow Correction Factors table. (Interpolation may be
required.)
Ct = .9625
Cs = .96
Select the elevation correction factors, Et and Es, from
the Elevation Correction Factors table. (No correction
necessary in this example, unit is at sea level.)
Et = 1.00
Es = 1.00
Using the Component Static Resistance table on
page 32, the ISP is calculated as follows:
Cabinet
4-row Wet Coil
2-in. Pleated Filter
ISP
ESP
TSP
.09-in. wg
.30-in. wg
.12-in. wg
.51-in. wg
.38-in. wg
.89-in. wg
III Calculate actual performance.
TC = TCb x Ct x Et
= 42.0 x .9625 x 1.00
= 40.42 MBtuh

Hydronic coil pressure drop — All of the factory’s hy-
dronic coils have a coefficient of velocity (Cv) resistance
factor assigned to assist in a more accurate determination
of water pressure drop (see Cv Factor by Coil and Unit Size
table below).
Coil pressure drop (ft wg):
∆P = (GPM2/Cv2 ) x 2.31
or
∆P = [GPM/(0.658 x Cv)]2
or
Calculating pressure drop:
Refer to the Water Pressure Drop for Cv Factor and
Water Flow Rate table. See example on page 22.
The Cv factor is equal to the flow rate of water in gpm
through a piping component when the pressure drop
through the component is 1.0 pounds per square inch
(psi), or 2.31 ft wg.
∆P (ft wg) = ∆P (psi) x 2.31
Use the Cv factor from the Cv Factor by Coil and Unit
Size table to determine the water coil pressure drop.
