IMPORTANT SAFETY INSTRUCTIONS Bryant 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 operators and potential operators of this equipment. ! ! WARNING: ! GENERAL HAZARDS ! ! The engine exhaust from this product contains chemicals known to the state of California to cause cancer, birth defects or other reproductive harm.
IMPORTANT SAFETY INSTRUCTIONS Bryant Air-cooled 7 kW, 12 kW and 15 kW Generators 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 operation. Avoid contact with bare wires, terminals, connections, etc., while the unit is running.

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 voltage is not connected to the unit or if it is below 168 volts AC, then the system set light will flash rapidly.
Section 1 — General Information Bryant Air-cooled 7 kW, 12 kW and 15 kW Generators 1.11 THE BATTERY If the AUTO/OFF/MANUAL switch is not set to its OFF position, the generator can crank and start as soon as the battery cables are connected. If the utility power supply is not turned off, sparking can occur at the battery posts and cause an explosion. 1.10 BATTERY INSTALLATION Fill the battery with the proper electrolyte fluid if necessary and have the battery fully charged before installing it.
Section 2 — Operation Bryant Air-cooled 7 kW, 12 kW and 15 kW Generators Be sure the utility power supply is turned off and the 7.5A and 15A fuses are removed from the generator control panel, or sparking may occur at the battery posts as the cables are attached and cause an explosion. Servicing of the battery is to be performed or supervised by personnel knowledgeable of batteries and the required precautions. Keep unauthorized personnel away from batteries. 12. Drain the oil and remove the oil filter.
Section 2 — Operation Bryant Air-cooled 7 kW, 12 kW and 15 kW Generators 2.3 AUTOMATIC TRANSFER OPERATION To select automatic operation, do the following: 1. Make sure the transfer switch main contacts are set to their UTILITY position, i.e., loads connected to the utility power source (Figure 2.2). 2. Be sure that normal UTILITY power source voltage is available to transfer switch terminal lugs N1 and N2. 3. Set the generator’s AUTO/OFF/MANUAL switch to AUTO. 4.
Section 2 — Operation Bryant Air-cooled 7 kW, 12 kW and 15 kW Generators 2.5 MANUAL TRANSFER OPERATION 2.5.1 TRANSFER TO GENERATOR POWER SOURCE To start the generator and activate the transfer switch manually, proceed as follows: 1. Set the generator’s AUTO/OFF/MANUAL switch to OFF. 2. Set the generator’s main circuit breaker to its OFF (or open) position. 3. Turn OFF the utility power supply to the transfer switch using the means provided (such as a utility main line circuit breaker).
Section 2 — Operation Bryant Air-cooled 7 kW, 12 kW and 15 kW Generators NOTE: The exerciser will only work in the AUTO mode and will not work unless this procedure is performed. The exerciser will need to be reset every time the 12-volt battery is disconnected and then reconnected. ! The exerciser WILL NOT work if dip switch 2 on the controller printed circuit board (Remote Not Auto) is ON. NOTE: 2.7.
