PRODUCT APPLICATION

Versatile Unit Arrangement OptionsOne of the unique traits of the Modular Hi-Rise fan coil

system is the versatile unit arrangements possible with this

factory-assembled, integrated package. When selecting the

best unit design configuration for your specific single- or

multi-story building, you are afforded the luxury of choosing

from numerous unit arrangement options which achieve

maximum efficiency while conserving floor space and

reducing installation costs.

Modular Hi-Rise fan coils are designed to be unobtrusive in

the room and, thus, are often positioned in a corner, along a

perimeter wall, as part of a partition separating two areas, or

as a stand-alone unit in the exposed configuration. Modular

Hi-Rise fan coils can be specified with up to three side-

discharge openings as well as a top discharge for ducted

applications.

Below are a few of the many arrangement possibilities of the

Modular Hi-Rise fan coil system.

movement by the internal piping structure is not intended

to replace necessary expansion compensation devices

that the consulting engineer may deem advisable for the

external riser system. External riser expansion/contraction

compensation and anchoring are the responsibility of the

consulting engineer and the installing contractor.

Riser Material, Sizing and InsulationBecause Modular Hi-Rise units are furnished with

field or factory installed risers, the riser type, size

and length, and insulation for each unit must

be determined based on the position of the

unit in the building. The chilled and hot water

risers and condensate drain are available in a

variety of diameters from 3/4" through 2-1/2".

See Mechanical Specifications section. All factory

furnished risers and riser extensions, including

condensate drains, are insulated for the full riser

length to eliminate the need for field furnished

insulation. Other materials to accommodate

such critical specifications as riser expansion and

between-the-floor fire proofing must be field

furnished and installed by others. Consult the

factory for special Applications.

Riser sizing is normally based on the water flow

requirements of each unit and the units above and

below the unit in the riser column depending on

the type of system being used. A common design

criteria is to select the risers to limit water velocity

at four to seven feet per second. Using this method,

risers may be reduced in size as the water flow

reduces from floor to floor. Uniform riser sizing may

be used on shorter buildings where the additional

riser expense would likely be offset by a greater

savings in unit handling expense on the job.

Riser ExpansionIEC’s Modular Hi-Rise units are built to

accommodate modest expansion of the external risers.

Standard unit construction, including internal expansion

loops, allows for a maximum of ±3/4-inch of external riser

expansion/contraction. This only allows for expansion

between the unit and the riser. This allowance for the

Modular Hi-Rise SeriesELECTRIC HEATING

Electric heaters are available on IEC Modular Hi-Rise 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.

ConstructionHeater coils of high-grade resistance wire are supported by

ceramic insulators on plated steel brackets. These heating

elements are located at the discharge area of the motor/

blower. High limit thermal cutouts protect the unit in the

event of airflow loss. There are many special applications

and control sequences for electric heat. For special

applications please consult the factory.

STANDARD FEATURES AND OPTIONS, Cont’d.

As detailed in the table below, we offer a control for most of our customer’s needs. Additional controls and devices are available to meet even the most demanding operating logic.

3-speed Fan ControlAll of our basic control schemes utilize a 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)An optional low voltage control is available with all of our control schemes.

Condensate Overflow SwitchThis optional switch shuts down the unit when the water level in the drain pan reaches an unsafe level. Building code changes in much of our country may require this type of device.

Service SwitchesWe offer optional service switches for use by maintenance and service personnel.

FusingWe offer optional incoming power fusing as well as blower motor and control sub-fusing for units that use electric heat.

Return Air/Access Panel ApplicationControl Mounting Options Panel

1. Surface mounted controls: This requires a a tile ring mounted above the return air panel and quick-connect plug wiring on the thermostat. After the drywall/sheetrock has been applied to the cabinet, the thermostat plug will be attached to a matching plug in the unit and the thermostat will be fastened to the tile ring. (Not available for MXY models)

Specifications:Frame and blades are 6063 extruded aluminum alloy with 200-

R1 satin anodized finish. The frame has a typical wall thickness

of .050" and is separated from the blades with injection-molded

nylon bushings. This method of assembly minimizes corrosion

and vibration. The frame mounting holes are dimpled, allowing

for a counter-sunk fastener head appearance.

All blades are airfoil in design, individually adjustable and

spaced 3/4" on center. At the outer edge of the frame is a

specially engineered channel which retains an extruded

flexible vinyl bulb gasket that produces a positive air seal

at the mounting surface, minimizing smudging.

An optional opposed blade damper is screwdriver-

operated through the face of the unit and has the same

extruded aluminum construction and injection-molded

nylon bushings.

The unit achieves an effective area of 80% with the blades

set at a 0° pattern, thus eliminating high velocity and

pressure drop at the grille face. Wider deflection with

reduced throw may be achieved at the 22° and 45° blade

settings with slightly increased sound levels.

Suitable for sidewall application. Available in clear

anodized, white or a variety of custom colors. Contact the

factory for available optional colors and color chart.
