Features/Benefits
The 42BHE, BVE belt drive
fan coil units provide yearround comfort air
conditioning with central
station operating economy.
A variety of coil options
reduces first cost
Four, 6 or 8-row cooling coils combine
needed capacities with the most efficient heat transfer surface. For
4-pipe systems, select from two splitcoil options. Standard coils consist of
aluminum fins securely bonded to
1
/2-in. OD seamless copper tubes.
Each fin’s aluminum collar ensures accurate control of the fin spacing, while
completely covering the tubes to
lengthen coil life. All coils also feature
manual air vents, with optional automatic air vents available. Special coils
are also available with stainless steel
end sheets and bottom coil baffles. For
custom applications, special coils are
available with lower pressure drops.

INTERNAL FEATURES OF A 42BHE FAN COIL UNIT
A42-472TF
Fan wheels are designed to
provide low operating costs
The forward-curved, centrifugal,
double-inlet fans are statically and
dynamically balanced at the factory to
minimize transmission of vibration
to the building structure.
In addition, the blower is isolated
from the cabinet by rubber isolators,
and the blower is isolated from the duct
connections by foam.
All motors (single and three phase)
are UL (Underwriters Laboratories) listed or equivalent, factory wired, single
speed with thermal overload protection and are continuous duty rated.
Motors are supplied with permanently
lubricated bearings, class-B insulation
and are open drip-proof. The motor
mount has an adjustable platform for
easy belt adjustment. The motor is resilient mounted (up to 2 hp) or rigid
base mounted (3 to 5 hp) for vibration
free installation. Drives are pre-set at
the factory for the specific airflow at
static pressures as ordered. An adjustable pitch pulley allows cfm balancing
to meet system requirements.
connections for ducts is recommended.
One-in. duct collars on discharge and
on return are furnished standard. These
integral duct collars cut installation time
and labor expense.
Durable construction means
easy-to-maintain units
The 42BHE,BVE fan coil casings are
fabricated from heavy-gage galvanized
G90 steel, reinforced for maximum
rigidity and structural strength. Optional one-inch double wall construction,
perforated or solid lined, is also available. Removable side panels with toolless camlock fasteners allow easy access for servicing interior components.
One-inch matte surface, fiberglass
thermal/acoustical insulation lines the
fan coil cabinets to prevent sweating
and to muffle sound transmission. Premium anti-microbial fiberglass, foil
faced, and closed cell insulations are
also available to address IAQ (indoor
air quality) concerns.
The stainless steel, double-sloped
condensate drain pan is removable for
ease of cleaning, and all models include primary and secondary drain
connections to provide back up in case
the main connection is plugged.
Slide-in return-duct collar filter
makes it possible to remove and replace the filter without disturbing
return air ductwork. A standard 2 in.
and optional 4 in. filter rack allow different filter types, thickness, and efficiency to address IAQ requirements.
Complete factory assembly
minimizes on-the-jobsite costs
and problems
Compact, lightweight units are designed
for easy mounting. For horizontal units,
knockouts designed to accept
threaded rods are provided on the top
and bottom of each corner of the unit.

The 42BHE and 42BVE 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 eliminate the need to manually remove air from the system.
When wet, washers swell and seal the system.
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. Reheat operation
is standard. Preheat is available as an option for hydronic
coil. For DX/HW (hot water) coils, preheat position is
standard. Steam coils are available with a factory special
quote.
Controls — Factory-installed optional controls include
an interlocking disconnect switch, heater power fusing,
24-v Class 2 transformer (40-va), 8-pole control terminal
strip, auto reset temperature limit switch, airflow safety
switch, motor power fusing, motor control contactor, and a
24-v condensate overflow switch.
Electric heat — Total electric heat eliminates the requirement for a boiler. Heating and/or cooling may be available
on an individual basis throughout the year. Resistance
electric heat is available from 1.0 kW to 39.9 kW (refer to
electric heater data table for availability per unit) with
single-stage or multiple-stage, single power source.
Voltages:
• 115-v, 208-v, 230-v and 277-v single-phase 60 Hz
• 208-v, 230-v and 480-v three-phase 60 Hz
• 220-v single-phase 50 Hz
• 380-v three-phase 50 Hz
Electric heat is available with the following staging options
(3-phase staging is balanced).
• 1 to 12 kW 1 stage only — single phase
• 3 to 12 kW 1 or 2 stage only — single phase
• 1 to 39.9 kW 1 stage only — 3 phase
• 4 to 39.9 kW 1 or 2 stage only — 3 phase
• 12 to 39.9 kW 1, 2, or 3 stage — 3 phase
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. An auto
and manual thermal limit switch 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.
Insulation — Tuf-Skin™ II (1-in. thick) insulation is
standard. Also available is 1-in. closed cell, 1-in. epoxy
coated fiberglass edge sealed, or 1-in. foil-faced insulation.
Motors — A wide selection of standard motors provides
efficient operation in ducted applications with excellent
performance with up to 2.5 in. of total static pressure. All
standard motors contain internal thermal overload protection. The overload automatically resets when the temperature returns to a safe limit. These thermal overloads, when
coupled with the motor contactor, replace the need for a
motor starter. Available motor options include:
• 115-v, 208-v, 230-v and 277-v single-phase 60 Hz
• 208-v, 230-v and 460-v three-phase 60 Hz
• 220-v single-phase 50 Hz
• 380-v three-phase 50 Hz
• Open drip-proof motors
• External junction box
Field-installed accessories
Mixing boxes — Mixing boxes can be used when outside
air is required for ventilation. Pre-assembled at the factory
and shipped separately with base rails for field installation,
mixing boxes include a linkage kit consisting of two crankarms, 2 swivels and either a 25 in. long (for sizes 06-16) or
a 34 in. long (for sizes 20-40)

UNIT HAND
Application data
Multitude of applications
These units can be floor or ceiling mounted, are available
with a variety of options that can meet the design requirements, and provide a low cost solution for a multitude of
applications.
Standard horizontal and vertical blower coil applications — Where the application calls for cooling capac-
ities or external static pressures that can not be met with
standard or high performance direct drive fan coil units,
use a Carrier standard horizontal or vertical blower coil.
Outside air applications — With the availability of
larger capacities, a variety of optional coils, mixing boxes,
and the capability of delivering air through long duct runs,
the belt drive units are ideal for handling outside air. When
used as outside air units, the heating coil should be in the
preheat location (consult Carrier’s application engineering
group).
Large public areas — These units are ideal for applications with a large common area such as restaurants, airports, sports arenas, stadiums, private boxes, gymnasiums,
exercise areas, locker rooms, atriums and foyers, auditoriums, shopping malls, and casinos, to name a few.
Basic definitions
Unit hand — When facing the supply air outlet from the
front of the unit (air blowing in your face), your right hand
will be the right hand side of the unit and your left hand the
left hand side of the unit.
Vertical units are typically installed on a pad. Ensure
adequate pad height for proper trapping of the condensate
drain.
Acoustical considerations
With sound becoming more of a concern to design engineers, building owners, and occupants, proper consideration should be given to the selection and placement of
these units.
Whenever possible, avoid placing these units above an
occupied space. To further reduce the sound level, use
additional measures such as: using flexible duct connectors;
lining the main supply and return ducts with acoustical
absorption material; locating the return-air grilles as far
away from the unit as possible; and using three-phase
motors.
Operating limitations
The fan curves outline the airflow and static pressure range
where it is acceptable to run these units. Running the belt
drive units outside this range could lead to drastically
reduced bearing life and premature wheel failure. In cooling applications, this could also result in moisture carry
over. In addition, running the fan at its maximum fan speed
will increase the power requirements and generate higher
sound levels.
On units with electric heat, the minimum airflow shown
on the fan curve must be maintained to prevent excessive
discharge temperature and electric heat safety trips. For
leaving discharge air temperatures greater than 104 F
(40 C), contact the applications engineering group.
Seismic certification
An optional seismic structural upgrade is available. Carrier’s belt drive series fan coil units with the seismic structural upgrade option are independently tested and certified
in accordance with IBC-2009 and OSHPD ICC-ES-AS156 with SDS of 1.93.
Installation considerations
The belt drive units are typically either suspended above
the ceiling or installed in a closet or mechanical room.
Attention should be paid to having enough clearance
around the units for service and maintenance.
Horizontal units are generally suspended above the ceiling using hanger rods that go through the corner knockouts provided in the units. External vibration isolation and
flex connections for ducts are recommended.
Quality
Carrier's belt drive fan coil units are listed by Intertek Testing Services (ITS). ITS's C-ETL-US listing signifies that
Carrier's belt drive fan coil units have been examined by
ITS and comply with the minimum requirements of U.S.
and Canadian national product safety standard, UL 1995/
CSA C22.2 No. 236, and that the manufacturing site has
been audited. ITS's re-examination service includes periodic visits to the factory to ensure continued compliance
for all listed products.
Every unit is tested and inspected at the factory for trou-
ble-free start-up.

PIPING COMPONENTS
SYMBOL/SKETCH DESCRIPTION
MANUAL AIR VENT: Threaded brass needle valve
with screwdriver slot for adjustment.
Application — Body brazed into high point of heat-
ing and cooling coils for bleeding air from coil. Standard item on all hydronic coils (not used on steam
or DX coils). Should not be used in lieu of main system air vents.
AUTOMATIC AIR VENT: Nickel plated brass valve,
fiber-disc type, with positive shut-off ballcheck and
quick vent feature via knurled vent screw.
Application — Optional replacement for manual air
vent. Automatically passes minute quantities of air
through the fiber discs which expand upon contact
with water, completely sealing the valve. As air
accumulates, the fiber discs dry and shrink, repeating the cycle. Not recommended for removing large
quantities of air encountered during initial start-up
or subsequent draining and refilling. Should not be
used in lieu of main system air vents.
