Configurator HE-T-KW-CW Type H, A, E, N (see below) Cabinet Width 21 = 21” 24 = 24”* kW Size 10 = 9.6 kW 15 = 14.4 kW 20 = 19.2 kW* 25 = 24 kW* 30 = 28.8 kW* Type All models – ECM™ blower motor, setup selection of four cooling sizes, 50% continuous air (fan – on setting). High efficient air circulation at about 50-watt. H = Full WarmFlo capability with outdoor sensor. This provides warm air outlet temperature dial selection and supply air ramp up with the decrease of outdoor temperature.
Inlet Cabinets Factory optional cabinets can be configured with this Electric Furnace. Typically these are designed for upflow applications; however, the heat pump coil cabinet could be used in other positions. Side Entry, Filter Cabinet Return air can be ducted into either side, 15-⅜” x 19” cutout hole is provided with one filler plate. Easy access door for checking and changing filter. Adjustable rails are provided for standard 4” x 20” x 20” pleated filter.
General Comments Upflow/Downflow/Horizontal The arrangement of refrigerant coil, hydronics coil, and built-in electric elements need to follow specific air direction or airflow rules, but the orientation of this Electric Furnace is not critical. For upflow and horizontal standard air conditioning applications, the A-coil is mounted at the blower outlet with field provided plenum or manufacturer’s case coil. All models contain GE ECM™ Series 2.3 blower motors.
Installation Checkout Attached to this manual is a warranty certification and checkout procedure. This must be completed and returned for warranty coverage. This is the responsibility of the contractor or company which “sold the job” and is assuming responsibility to the end customer. Warranty Statement See the last page of this manual for detailed limited warranty coverage explanation. Application General The configurator, previous page, details several product types.

Installation Requirements 1. All installation work must be performed by trained, qualified contractors or technicians. Electro Industries, Inc., sponsors installation and service schools to assist the installer. Visit our web site at electromn.com for upcoming service schools. WARNING ALL ELECTRICAL WIRING MUST BE IN ACCORDANCE WITH NATIONAL ELECTRIC CODE AND LOCAL ELECTRIC CODES, ORDINANCES, AND REGULATIONS. WARNING OBSERVE ELECTRIC POLARITY AND WIRING COLORS.
Mechanical Installation Clearances and Accessibility Zero clearance is allowed on all sides for combustible materials. However, 36” should be allowed at the front for operation, maintenance, and service. To reduce the risk of rusting and appearance, do not install the unit directly on the ground or on a floor that is likely to be wet. In such environments the unit must be elevated by use of a sturdy non-porous material.
Whether this unit is sitting on or attached to an inlet cabinet, field designed inlet cabinet, or horizontal supports; verify proper support and mechanical strength is provided within the system installation. Rubber isolation pads should be used where possible to reduce sound and vibration transmission. WARNING WHEN HANGING THIS UNIT, THERE MUST BE UNDER SUPPORTS WHICH DISTRIBUTE THE HANGING CHAINS ACROSS THE SURFACE OF THIS UNIT, DO NOT SIMPLY DRILL A HOLE AND USE A COUPLE OF HANGING BOLTS.
Horizontal, Air Conditioning Similar to upflow above, the air conditioning coil is positioned at the blower outlet. Depending upon the coil type and drip pan it is positioned in a field constructed plenum as required. As horizontal, the return air would enter the blower end of the cabinet with a typical packaged 20” x 20” filter cabinet. Horizontal, Heat Pump As emphasized above, the heat pump coil must be at the blower inlet.
Electrical Installation WARNING TO AVOID THE RISK OF ELECTRIC SHOCK OR DEATH, WIRING TO THE UNIT MUST BE PROPERLY GROUNDED. FAILURE TO PROPERLY GROUND THE UNIT CAN RESULT IN A HAZARD LEADING TO PERSONAL INJURY OR DEATH. Line Voltage The nameplate and/or Installation and Operating Manual specification page provides kW rating and operating current requirements for each specific model. Select the proper wire size to comply with your type of wire routing and NEC field wiring requirements.
Cooling, Special Dehumidification The BK tab and the BK peg jumper provide the industry standard 12% blower speed reduction to “pull out” additional moisture from the air. Provide an external humidistat between BK and R and pull or permanently disconnect the BK jumper. With the BK terminal at 0 volts the 12% blower speed reduction is activated. Utility Load Control If applicable for your installation and your utility authorized electric rate, at the bottom of the control board is a blue wire jumper.
Electric Furnace Control – Inside View, Right Board Green, next to Fuse 24-volt power connected and fuse good. Red, next to W Call for electric heat, also represents the input signal (yellow wire) to the WarmFlo control board. Green, Cool Conventional H/C stat has an active Y function or heat pump stat reversing valve is in the cool mode (will depend upon proper setup with RV logic jumper). For 2-speed AC this LED is illuminating during high speed. Amber Represents action within ECM™ blower motor.
