Page 4: Inlet Cabinets
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”... -
Page 5: General Comments
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. The special Electro Industries interface board allows hookup for heat/cool conventional or basic heat pump room thermostat. Blower speed setup and WarmFlo sensor control are separate for cooling and heating (unique). -

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.

Page 9: Mechanical Installation
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. - Page 10 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...
- Page 11 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.

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. -

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. - Page 14 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).
