PORTFOLIO

CBY - Horizontal Telescoping Hideaway 200 CFM to 1200 CFMThe 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.

CHY - Horizontal Hideaway 200 CFM to 1200 CFMThe 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.


Horizontal SeriesPORTFOLIO, Cont’d.

CXB - Horizontal Cabinet 200 CFM to 1200 CFMThe 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.

CPY - Horizontal Hideaway with Plenum 200 CFM to 1200 CFMThe 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.

NOTES: 1. All heaters are single stage and single phase. 2. Heaters over 48 Amps are subdivided and fused. 3. Electric Heating Capacities (BTUH) = Heater kW x 3413. 4. Electric Heater Amperage = (Heater kW x 1000)/Applied

Voltage) 5. Consult factory for 50 Hz applications. 6. High and medium speed only.

Electric Resistance HeatingElectric heaters are available on IEC Horizontal Series fan coil

units for the following applications.

Total Electric HeatTotal 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.

Individual room controls can be supplied for either manual

or automatic changeover.

Auxiliary Electric HeatAuxiliary electric heat is ideal for tempering room air

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.

ConstructionThe heater coils of high-grade resistance wire are supported

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

special applications and control sequences for electric heat.

For special applications, please consult the factory.

MOTOR DATA

Thermal Overload Protection and ETL ListingAll permanently lubricated split-capacitor motors furnished by IEC contain internal thermal-

overload 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.

Three-speed Fan ControlAll 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

performance is not required.

Low Voltage Control (24 V)A low voltage control is available with all of our control

schemes.

Condensate High Level SwitchThis 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.

Service SwitchesWe offer concealed service switches for use by maintenance

and service personnel to shut off the power while working

on the unit.

FusingWe offer incoming power fusing for all units as well as

blower motor and control sub-fusing for units that use

electric heat. The blower motor and control sub-fusing

(single power source wiring) is required when single source

power with electric heat is specified.

PIPING PACKAGES (TYPICAL)

Two-way Motorized Control ValveIn a two-way motorized control valve package, the motor

drives the valve open, and a spring returns the valve to a

normally closed position. No water flows with the unit off.

The standard supply connection from the coil will accept

a swaged copper fitting for field brazing. As an option, this

connection may be factory furnished with a union. When a

swage is necessary, it becomes part of the valve package.

The isolation, or ball, valve in the return piping is shipped

loose for field installation.

Two-way Motorized Control Valve with ChangeoverIn 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

a small amount of water to flow from the supply to the

return piping when the control valve is closed. The strap-

on 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.

Three-way Motorized Control ValveIn a three-way motorized control valve package, a diverting

valve controls water flow to the coil. When the unit is off,

water bypasses the coil and flows directly to the system

return. A balancing valve may be specified in the bypass line

to permit equal flow balancing.

NOTES: 1. Please note that project specifications for system 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. Factory-provided 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.
