Carrier 58HDX Electrostatic Discharge Esd Precautions, General, Fire / Explosion Hazard

58HDX

!WARNING

FIRE / EXPLOSION HAZARD

Failure to follow this warning could cause personal injury, death, or property damage.

Never store anything on, near, or in contact with the furnace, such as:

1.Spray or aerosol cans, rags, brooms, dust mops, vacuum cleaners, or other cleaning tools.

2.Soap powders, bleaches, waxes or other cleaning compounds, plastic or plastic containers, gasoline, kerosene, cigarette lighter fluid, dry cleaning fluids, or other volatile fluids.

3.Paint thinners and other painting compounds, paper bags, or other paper products.

Installing and servicing heating equipment can be hazardous due to gas and electrical components. Only trained and qualified service agency personnel should install, repair, or service heating equipment. Untrained personnel can perform basic maintenance functions described in User’s Information Manual such as cleaning and replacing air filters. All other

ELECTROSTATIC DISCHARGE (ESD)

PRECAUTIONS

!CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution may damage furnace components.

Electrostatic discharge can affect electronic components. Take precautions during furnace installation and servicing to protect the furnace electronic control. Precautions will prevent electrostatic discharges from personnel and hand tools which are held during the procedure. These precautions will help to avoid exposing the control to electrostatic discharge by putting the furnace, the control, and the person at the same electrostatic potential.

AIRFLOW

operations must be performed by trained and qualified service agency personnel. When working on heating equipment, observe precautions in the literature, on tags, and on labels attached to or shipped with the unit and other safety precautions that may apply.

Follow all safety codes including the National Fuel Gas Code (NFGC) NFPA 54-2006/ANSI Z223.1-2006 in the USA; National Standard of Canada, Natural Gas and Propane Installation Code CSA B149.1 (NSCNGPIC) in Canada; and the Installation Standards, Warm Air Heating and Air Conditioning Systems (NFPA 90B) ANSI/NFPA 90B. Wear safety glasses and work gloves. Have a fire extinguisher available during start-up and adjustment procedures and service calls.

ELECTRICAL SHOCK AND UNIT DAMAGE HAZARD

Failure to follow this caution may result in personal injury or damage to furnace.

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.

GENERAL

This furnace van be installed as a direct vent (2-pipe) or non-direct vent (1-pipe)condensing gas furnace. These instructions are written as if the furnace is installed in an upflow application. An upflow furnace application is where the blower is located below the combustion and controls section of the furnace, and conditioned air is discharged upward. Since this furnace can be installed in any of the 4 positions shown in Fig. 1, you may need to revise your orientation to component location accordingly.

Fig. 1 - Multipoise Orientations

1.Disconnect all power to the furnace. DO NOT TOUCH THE CONTROL OR ANY WIRE CONNECTED TO THE CONTROL PRIOR TO DISCHARGING YOUR BODY’S ELECTROSTATIC CHARGE TO GROUND.

2.Firmly touch a clean, unpainted, metal surface of the furnace chassis which is close to the control. Tools held in a person’s hand during grounding will be satisfactorily discharged.

3.After touching the chassis you may proceed to service the control or connecting wires as long as you do nothing that recharges your body with static electricity (for example; DO NOT move or shuffle your feet, DO NOT touch ungrounded objects, etc.).

4.If you touch ungrounded objects (recharge your body with static electricity), firmly touch furnace again before touching control or wires.

5.Use this procedure for installed and uninstalled (ungrounded) furnaces.

6.Before removing a new control from its container, discharge your body’s electrostatic charge to ground to protect the control from damage. If the control is to be installed in a furnace, follow items 1 through 5 before bringing the control or yourself into contact with the furnace. Put all used AND new controls into containers before touching ungrounded objects.
