1 TEHNIL GUIDE MODELS: MV MODULR VRIBLE SPEED IR HNDLERS FOR USE WITH SPLIT SYSTEM OOLING & HET PUMP FM BLOWERS 3-5 TON OILS OPTIONL 1 & 3 ELETRI HETERS Due to continuous product improvement, specifications are subject to change without notice. Visit us on the web at: dditional rating information can be found 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, downflow, 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. FETURES Blowers - s 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 motors provide a selection of air quantities to match any application. ll 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. ll models have 1 inch foil face fiber glass insulation, providing a thermal insulation value of R-4.2. 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-410 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. ll 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. s 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. ommunication - These models may be connected as part of a communciations system using a 4-wire connection bus. ccessories - full line of matching accessories available for use with the blower and coils to allow any type application. LIMITTIONS These units must be wired and installed in accordance with all national and local safety codes. Voltage limits are as follows: IR HNDLER VOLTGE NORML OPERTING VOLTGE RNGE* 208/ * Rated in accordance with RI Standard 110, utilization range. ir flow must be within the minimum and maximum limits approved for electric heat, evaporator coils and outdoor units.
