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.

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.

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.

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.
