1 TEHNIAL GUIDE SINGLE PIEE MODULAR AIR HANDLERS FOR USE WITH SPLIT SYSTEM OOLING & HEAT PUMP MODELS: FM BLOWERS 2-5 TON OILS OPTIONAL 1 & 3 ELETRI HEATERS Due to continuous product improvement, specifications are subject to change without notice. Visit us on the web at: ISO 9001 ertified Quality Management System DESRIPTION This unique modular system allows the flexibility to handle any application. These versatile coils and blowers may be used for upflow, down-flow, or horizontal left or right applications. They may be combined to function as a cooling only unit or with a heat pump including electric heat for 1 and 3 phase applications. The blower and electric heater could be used as stand alone electric furnaces. FEATURES Blowers - to match any air flow or voltage requirement. The compact size allows easy installation. Blowers are sized to deliver design air quantity both efficiently and quietly. The direct-drive, multi-speed blower motors provide a selection of air quantities to match any application. All models include a one-minute blower off delay as standard to enhance system efficiency ratings. The durable, pre-painted steel protects the unit against rust and corrosion. All models have 1 inch foil face fiber glass insulation, providing a thermal insulation value of R oils - Staggered rows of rifled copper tubes are mechanically expanded into enhanced surface aluminum fins to provide high heat transfer and long-lasting quality. The M multi-position coils may be used for upflow, downflow, and horizontal left or right applications. oil cabinets are insulated with 3/4" foil face insulation to prevent sweating. Thermal Expansion Valves - oils are ordered as Flex-coil unit without a factory installed mertering device. Flex-coil models allow for field installed R-22 or R-410A TXV s for added flexibility to meet refrigerant system choice. Electric Heaters - Both single and three phase electric heater models are available to match any requirement. All heaters include nickel-chromium elements with a 5-year limited warranty on 1 Ø heating elements and 1 year limited warranty on 3 Ø heating elements. Sequential operation is provided to control heaters in all models. ircuit breakers are used in 208/230 volt, single-phase heaters of 15 KW and larger. equipped with circuit breakers may be altered in the field to use multi-source power supply. Over-temperature limit switches provide protection from airflow loss with fusible link backup protection. NOTE: No heat kits are available for 115 Volt models. Accessories - A full line of matching accessories available for use with the blower and coils to allow any type application. LIMITATIONS These units must be wired and installed in accordance with all national and local safety codes. Voltage limits are as follows: BLOWER VOLTAGE VOLTAGE ODE NORL OPERATING VOLTAGE RANGE* / * Rated in accordance with ARI Standard 110, utilization range A. Air flow must be within the minimum and maximum limits approved for electric heat, evaporator coils and outdoor units. FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE

2 DIMENSIONS - (BLOWER WITH M OILS) NOTE: Power wiring may be brought into the unit through one of the knockouts in either the top or the left side panel. Multiple knockouts are provided to accommodate all of the electric heat and transformer accessories that are available. Use the knockouts that provide the best wire routing for the accessory being used.
