11 Riser Material, Sizing and Insulation Because 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 /4" through 2-/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 Expansion MAIMUM WATER TEMPERATURE IFFERENCES (ºF) IEC 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 ±/4-inch of external riser expansion/contraction. This only allows for expansion between the unit and the riser. This allowance for the THERMAL EPANSION OF COPPER RISERS EPANSION (INCHES PER FOOT) 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.

38 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. -speed Fan Control All of our basic control schemes utilize a -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 (24V) An optional low voltage control is available with all of our control schemes. Thermostats Condensate Float Switch This 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 Switches We offer optional service switches for use by maintenance and service personnel. Fusing We offer optional incoming power fusing as well as blower motor and control sub-fusing for units that use electric heat.

The frame has a typical wall thickness of.00" 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 /4" on center. At the outer edge of the frame is a Continued on next page.

42 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 screwdriveroperated 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 4 blade settings with slightly increased sound levels. Suitable for sidewall application.
