Units shall be listed by a nationally recognized safety-testing laboratory or agency, such as Underwriter s Laboratory (UL) or Environmental Testing Laboratories (Intertek-ETL). The air handler units shall be designed and AI performance listed to operate with the Series geothermal split condensing units. Each unit shall be pallet mounted and shipped using dense cardboard corners/top and stretch wrap for easy shipping damage inspection. asing and abinet The cabinet shall be fabricated from heavy-gauge galvanized steel and polyester powder coat paint to withstand 000 hours of salt spray testing. The interior shall be insulated with / -thick, multi-density, cleanable aluminum foil coated glass fiber with edges sealed or tucked under flanges to prevent the introduction of glass fibers into the discharge air. ne large blower compartment access panel shall be provided and shall be removable with supply and return ductwork in place. The internal components layout shall provide for major service with the unit in-place for restricted access installations. The blower assembly access shall be slide-out serviceable via a works-in-a-drawer design. The cabinet shall be convertible to horizontal or downflow applications by reconfiguring the cabinet using only a nut driver. The unit shall be zero clearance approved on any of its surfaces. The cabinet shall be divided into two cubes to facilitate easy transport up attic ladders when needed. Standard-size MEV filters shall be provided with each unit. efrigeration ircuit All units shall provide a fin tube air-to-refrigerant heat exchanger of the A coil design. The finned tube e-coated coil shall be sized for low-face velocity and constructed of lanced aluminum fins bonded to rifled copper tubes in a staggered pattern. The coil shall include an integral corrosion resistant e-coated galvanized steel drain pan. Blower Motor and Assembly The blower shall be an oversized direct drive centrifugal type with a dynamically balanced wheel. The housing and wheel shall be designed for quiet low outlet velocity operation and of galvanized or galvalume steel construction. Tight blower housing geometry shall not be permitted. The blower housing shall be removable from the unit without disconnecting the supply air ductwork for servicing of the blower motor through a works-in-a-drawer design. The high efficiency blower motor shall be a variable speed EM type. The blower motor shall be isolated from the housing by rubber grommets. The motor shall be permanently lubricated ball bearings and have thermal overload protection. Electrical A solid state electronic control module shall be provided for the control of the blower and each stage of electric heat. Single or dual circuit line voltage terminal blocks shall be provided for the air handler power supply. Fuse protection shall be provided for the VA control transformer.
