Extended 10-year limited parts warranty when product is registered online within 90 days of purchase for replacement or closing for new home construction. Description This unique modular system provides the flexibility to handle any application. These versatile JMVT blowers can be used for upflow, downflow, or horizontal left, or right applications. They can be combined with cased coils to function as a cooling only unit or with a heat pump including electric heat for 208-230-1 and 208-230-3 phase applications. The JMVT blower and 8HK electric heater kits can be used as stand alone electric furnaces. Features Next generation high -efficiency blower - delivers increased airflow and reduced blower watts by 10%, using a variable speed ECM motor Variable speed operation - provides flexibility in application as well as upgraded system efficiency Next generation insulation and gasket design - reduces thermal transmission paths and reduces sweating Electric heat kit - 8HK field -installed series available for easy installation and service application Designed for easy installation and service - casing size of 20.5 in., smooth sides, and rigid construction provide ease of attic access and tight applications. Front facing components, slide out blower, laser cut knock outs, and integrated duct flanges shorten install time. Cabinet air leakage - less than 2% at 1 in. W.C. external static pressure when tested in accordance with ASHRAE Standard 193 Long lasting quality - structural components made of post - powder painted aluminum or galvanized steel to prevent corrosion FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE 6269412-YTG-A-0922 List of sections Nomenclature Description............................................1 Features..............................................1 Nomenclature..........................................2 Dimensions and duct connections ......................... 3 Technical data.........................................3 Power wiring..........................................11 Accessories..........................................11 Limitations...........................................12 Typical applications .................................... 13 Control wiring.........................................13 Airflow data...........................................14 Brand J J = JCI air handler Type M M = modular blower Motor type V V = multi variable speed ECM E = multi standard ECM P = multi PSC Stage T S = single stage capable T = two stage capable V = variable stage capable Cabinet width (in.)
