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 elimi-
nate 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 require-
ment 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 protec-
tion. The overload automatically resets when the tempera-
ture 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 crank-
arms, 2 swivels and either a 25 in. long (for sizes 06-16) or
a 34 in. long (for sizes 20-40)
tion of an actuator.
