PORTFOLIO
CHY - Horizontal Hideaway
200 CFM to 1200 CFM
The Horizontal Hideaway (CHY) fan coil unit is designed
specifically to meet the many varied requirements for a
ceiling hideaway installation. The low-silhouette styling of
the CHY makes this unit ideally suited for drop-ceiling and
over-closet applications. Standard CHY units are provided
with a galvanized finish.
CBY - Horizontal Telescoping Hideaway
200 CFM to 1200 CFM
The Horizontal Telescoping Hideaway (CBY) fan coil unit is
mounted fully-recessed for ceiling-recessed applications. The
CBY’s telescoping frame with hinged panel adapts to any
ceiling type and ensures exact alignment of the panel with
the ceiling. The hinged-bottom panel provides easy access
to all internal components. Standard CBY units are provided
with a galvanized finish on the cabinet and powder-coat
paint finish on the bottom-access panel.

CPY - Horizontal Hideaway with Plenum
200 CFM to 1200 CFM
The Horizontal Hideaway with Plenum (CPY) fan coil unit
provides the same basic features of the CHY plus a return
air plenum for above-ceiling mounting in closets, hallways
or bathroom areas. The CPY design enables the unit to be
adapted to installations requiring return air ducts or to be
used as a return-air plenum with a unit-mounted filter and
filter-rack assembly. CPY units are shipped from the factory
ready for installation with the plenum section in place. No
field fabrication is required. CPY units are designed with
interchangeable panels so that the unit may be modified on
site to accommodate a rear or bottom return. Standard CPY
units are provided with a galvanized finish.
CXB - Horizontal Cabinet
200 CFM to 1200 CFM
The Horizontal Cabinet (CXB) fan coil unit is designed
specifically for exposed mounting in hotels, motels,
hospitals, nursing homes, offices or other commercial
establishments. With the CXB, valuable floor space is not
required, and its slim, attractively-styled cabinet blends
with all types of decor. Since there is no requirement for
duct work or structure modifications, the CXB is ideal for
retrofit applications. Standard CXB units are provided with a
powder-coat paint finish.

FEATURES & BENEFITS
Application Fit
• Optional airflow configuration (front supply, bottom
• Multiple cabinet choices are available in 7 nominal
CFM sizes for application in a variety of room layouts.
o
Horizontal Cabinet units (CXB) with aesthetically
pleasing cabinetry offer capacities that are ideal for
air conditioning in dormitories, small apartments,
schools and many other applications. Front supply,
bottom or rear return are available.
o
Horizontal Telescoping Hideaway units with
painted access panel (CBY) allows smooth fit up
to plaster or sheet rock ceilings. Standard units
include bottom louvered return air with the filter
located in the access panel.
o
Horizontal Hideaway models (CHY) units are
installed above the ceiling with or without ducted
supply air and open “soffit” return with an optional
ceiling-mounted filter-grille.
o
Horizontal Hideaway models with plenum (CPY)
units are installed above the ceiling with or
without ducted supply air and ducted return air.
The return air filter is either mounted on the unit
plenum or installed in an optional ceiling filtergrille.
supply, rear return or bottom return) to meet certain
design limitations.
• Outside air connections are available to meet
ventilation requirements and reduce field labor (CXB/
CBY/CPY).
• Wide variety of factory assembled valve packages to
meet desired controls specifications.
• Optional condensate overflow switch to address latest
building codes where required.
• Wide variety of optional insulation materials are
available to address IAQ concerns.
Ease of Installation
• Factory assembled valve packages minimize piping
work at the job site (shipped loose for field mounting).
• Optional unit mounted controls, service switches and
fusing minimize the electrical work required on site.
• Units are tagged at the factory for clear identification
on job site.
• Opposite end connection units may minimize the
piping work on renovation jobs.
Ease of Service
Design Flexibility
• Easy to use ratings program to speed up project
design.
• Standard and high capacity hydronic coils and DX coils
are available to match the heating and cooling loads of
• All components are accessible by simply removing the
access panel.
• Filters can be replaced without tools or by opening the
bottom panels on exposed units.
• Blower assembly easily removed from the rear of coil
the space.
• Optional powder-paint finish colors and grille
selections will complement most décors (exposed
units).
• CXB and CBY units ordered with optional rear return
are constructed with a solid bottom panel.
• Customizable cabinetry makes these units ideal for
renovation jobs or where special sizes are required to
for service and cleaning.
Quality and Safety
• Every unit is tested and inspected at the factory for
trouble free start-up.
• ETL and CETL listed.
• AHRI certified.

Total electric heat eliminates the requirement for a boiler.
Heating and/or cooling may be available on an individual
basis throughout the year. Two-pipe chilled water is used
for cooling; and the electric heater is used for heating.
Auxiliary electric heat is ideal for tempering room air
208 V
between seasons and during the cooling season when
chilled water is being circulated. Individual room controls
are supplied to provide electric heat only when chilled water
is being circulated. During regular heating season, heating is
provided by hot water being circulated in the system.
by ceramic insulators on plated steel brackets. These heat

elements are suspended directly in front of the fan outlet
between the blower and the coil. High limit thermal cutouts
protect the heater in the event of air failure. There are many
240 V
277 V
special applications and control sequences for electric heat.
For special applications, please consult the factory.

MOTOR DATA
Thermal Overload Protection and ETL Listing
All permanently lubricated split-capacitor motors furnished by IEC contain internal thermaloverload protection. The overload automatically resets when the temperature returns to a
safe limit. Electronics Testing Laboratories, Inc. approves the motor and thermal overload
combination at locked rotor conditions only.

STANDARD FEATURES & OPTIONS, Cont’d.
As detailed in the table on page 27, we offer a control
for most of the customer needs. Additional controls and
devices are available to meet even the most demanding
operating logic.
Condensate High Level Switch
This switch shuts down the unit when the water level in the
drain pan reaches an unsafe level. Building code changes in
much of the country now require this type of device.
Three-speed Fan Control
All of our basic control schemes utilize a 2- or 3-speed
switch to modulate the cooling output, to maximize the
percentage of latent heat removal, and to further minimize
the sound level when maximum cooling or heating
Service Switches
We offer concealed service switches for use by maintenance
and service personnel to shut off the power while working
on the unit.

Two-way Motorized Control Valve with
Changeover
In a two-way motorized changeover control valve package,
the motor drives the valve open, and a spring returns the
valve to a normally closed position. No water flows through
the coil with the unit off. The aquastat bypass line allows
pressure, pressure drop limitations and flow rate
should be checked prior to selecting specific
components or the valve package size.
2. The supply and return piping connections of the
factory-provided valve package are either swaged for
field brazing (standard) or union fitted (optional) for
connection to the coil.
3. Consult IEC’s Valve Packages and Piping Components
manual or your local representative for detailed
piping and valve application information. Factoryprovided valve packages are assembled, brazed,
wired electrically and dry-fit to the coil connections
before shipping. Field brazing to the coil completes
the installation. Some applications dictate shipping
isolation valves loose.

return piping when the control valve is closed. The strapon aquastat senses whether the flowing water is cold or
hot and switches a contact closed to provide automatic
summer/winter changeover (ACO) for the system.
