ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONSPROCEDUREElectrostatic discharge can affect electronic components.Take precautions during furnace installation and servicing toprotect the furnace electronic control. Precautions will pre-vent electrostatic discharges from personnel and hand toolswhich are held during the procedure. These precautions willhelp to avoid exposing the control to electrostatic dischargeby putting the furnace, the control, and the person at the sameelectrostatic potential.1. Disconnect all power to the furnace. DO NOT TOUCH THECONTROL OR ANY WIRE CONNECTED TO THE CON-TROL PRIOR TO DISCHARGING YOUR BODY’S ELEC-TROSTATIC CHARGE TO GROUND.2. Firmly touch a clean, unpainted, metal surface of the furnacechassis which is close to the control. Tools held in a person’shand during grounding will be satisfactorily discharged.3. After touching the chassis you may proceed to service thecontrol or connecting wires as long as you do nothing thatrecharges your body with static electricity (For example: DONOT move or shuffle your feet, DO NOT touch ungroundedobjects, etc.).4. If you touch ungrounded objects (recharge your body withstatic electricity), firmly touch furnace again before touchingcontrol or wires.5. Use this procedure for installed and uninstalled (ungrounded)furnaces.6. Before removing a new control from its container, dischargeyour body’s electrostatic charge to ground to protect thecontrol from damage. If the control is to be installed in afurnace, follow items 1 through 5 before bringing the controlor yourself into contact with the furnace. Put all used ANDnew controls into containers before touching ungroundedobjects.7. An ESD service kit (available from commercial sources) mayalso be used to prevent ESD damage.INTRODUCTIONThe models 58UHV and 58UXV Series 110 or 120 Furnaces areavailable in sizes 60,000 through 117,000 Btuh input capacities.These furnaces use variable-speed motors manufactured by Gen-eral Electric (GE) and known as ICM2+ motors. They areintegrated control motors, which include a pre-programmed micro-processor-based control to precisely control the selected airflowrates. The motor will be referred to as ICM2+ in the rest of thisdocument.Table 1—Dimensions (In.)UNIT SIZE A D E FLUE COLLAR SHIP.

For airflow requirements above 1800 CFM, see Air Delivery table in Product Data literature for specificuse of single side inlets. The use of both side inlets, a combination of 1 side and the bottom, or thebottom only will ensure adequate return air openings for airflow requirements above 1800 CFM.NOTES:5 3⁄8†5 13⁄16†2 3⁄8†2 11⁄16†1†2 1⁄16† 19†13⁄16†7⁄8-IN.
