  • Page 4: Safety Rules

    IMPORTANT SAFETY INSTRUCTIONS Air-cooled 7 kW, 12 kW and 15 kW Generators  SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe operation be copied and posted near the unit’s installation site. Safety should be stressed to all opera- tors and potential operators of this equipment.

  • Page 5: Standards Index

     ELECTRICAL HAZARDS • All generators covered by this manual produce dangerous electrical voltages and can cause fatal electrical shock. Utility power delivers extremely high and dangerous voltages to the transfer switch as does the standby generator when it is in opera- tion.

  • Page 6: Section 1 - General Information

    Section 1 — General Information Air-cooled 7 kW, 12 kW and 15 kW Generators DANGER  Only qualified electricians or contractors should attempt such installations, which must comply strictly with applicable codes, standards and regulations. UNPACKING/INSPECTION After unpacking, carefully inspect the contents for damage.

    SYSTEM SET LED The “System Set” LED is lit when all of the following conditions are true: 1. The AUTO/OFF/MANUAL switch is set to the AUTO position. 2. The utility voltage being supplied to the unit is being sensed by the PCB. If the utility sense volt- age is not connected to the unit or if it is below 168 volts AC, then the system set light will flash rapidly.

     Lead-acid batteries present a risk of fire because they generate hydrogen gas. The following procedures are to be followed: • DO NOT SMOKE when near the battery; • DO NOT cause flame or spark in battery area; and • Discharge static electricity from body before touch- ing the battery by first touching a grounded metal surface.

  • Page 24: Attention After Submersion

    Section 4 — Maintenance Air-cooled 7 kW, 12 kW and 15 kW Generators  The exhaust from this product gets extremely hot and remains hot after shutdown. High grass, weeds, brush, leaves, etc. must remain clear of the exhaust. Such materials may ignite and burn from the heat of the exhaust system.
