EH EH PB - S - HE - Light emitting diode - reen 0-0V elay coil Electric Heat ontactor Polarized connector Power block DIP package 0 position Heater element Breaker Dual Power Supply onnections If two separate circuits are used to supply power to the auxiliary heat kit, the Installer will need to verify that each leg of the auxiliary heat circuit breakers are wired from the power supply correctly in order for the electric heat kit to operate properly. This can be done by measuring the supply side voltage of the auxiliary heat circuit breakers. Put a voltmeter on the L side of ircuit Breaker ne and on the L side of ircuit Breaker Two. The voltmeter should read approximately 0 volts. If the meter reads high voltage, the auxiliary heat breakers need to be rewired so that breakers in the auxiliary heat kit match the wiring of the Disconnect Panel breakers. Meaning, L and L from one breaker in the disconnect panel must connect to L and L at one of the auxiliary heat circuit breakers and L and L from the other breaker in the disconnect panel must connect to L and L of the other auxiliary heat circuit breaker, making sure that the L and L from each disconnect breaker matches the L and L at each of the auxiliary heat breakers.

11 ontractor: - Tons 0Hz Engineering uide Specifications eneral The air handler shall provide vertical upflow, downflow, or horizontal configurations in one package. 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). 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-hydronic heat exchanger of the A coil design. The finned tube 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. and Assembly The blower shall be an oversized direct drive centrifugal type with a dynamically balanced wheel.
