2 All other operations shouldbe performed by trained service working on the equipment, observe precautions in theliterature and on tags, stickers, and labels attached to all safety codes. Wear safety glasses and workgloves. Keep quenching cloth and fire extinguisher nearbywhen brazing. Use care in handling, rigging, and settingbulky these INSTRUCTIONS thoroughly and follow all warningsor cautions included in literature and attached to the local building codes and National Electrical Code(NEC) for special requirements. In Canada, refer to currenteditions of the Canadian Electrical Code, CSA Recognize safety information. This is the safety alertsymbol !!. When you see this symbol on the unit and ininstructions or manuals, be alert to the potential for these signal words: DANGER,WARNING, and CAUTION. These words are used with thesafety alert symbol.

3 DANGER identifies the most serioushazards which will result in severe personal injury or signifies hazards which could result in personalinjury or death. CAUTION is used to identify unsafepractices which may result in minor personal injury orproduct and property damage. NOTE is used to highlightsuggestions which will result in enhanced INSTALLATION ,reliability, or operation.!WARNINGELECTRICAL SHOCK HAZARDF ailure to follow this warning could result in personalinjury or installing, modifying, or servicing system, mainelectrical disconnect switch must be in the OFFposition. There may be more than 1 disconnect out and tag switch with a suitable warning !EQUIPMENT DAMAGE HAZARDF ailure to follow this caution may result in equipmentdamage or improper not bury more than 36 in.
