INTRODUCTION Thank you for purchasing this model of the standby generator set product line by Generac Power Systems. Every effort was expended to make sure that the information and instructions in this manual are both accurate and current at the time the manual was writ- ten.
IMPORTANT SAFETY INSTRUCTIONS QUIETSOURCE™ Liquid-cooled 30 kW Generators SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe operation be copied and posted in potential hazard areas. Safety should be stressed to all operators, potential operators, and service and repair technicians for this equipment. SAVE THESE INSTRUCTIONS –...
• Inspect the generator regularly, and promptly repair or replace all worn, damaged or defective parts using only factory-approved parts. • Before performing any maintenance on the generator, disconnect its battery cables to prevent accidental start-up. Disconnect the cable from the battery post indicated by a NEGATIVE, NEG or (–) first.
Section 1 - General Information QUIETSOURCE™ Liquid-cooled 30 kW Generators GENERATOR This equipment is a liquid-cooled, engine-driven gen- erator set. The generator is designed to supply elec- trical power that operates critical electrical loads during utility power failure. The unit has been facto- ry-installed in a weather resistant, all aluminum enclosure and is intended for outdoor installation only.
GENERATOR FUEL SYSTEM The unit has been factory tested and adjusted using a natural gas fuel system. If propane (LP) gas is neces- sary. Refer to Section 1.11, Fuel Consumption. Fuel pressure for a natural gas set up should be five inches to 14 inches of water column (0.18 to 0.5 psi) at all load ranges.
Section 1 — General Information QUIETSOURCE™ Liquid-cooled 30 kW Generators Figure 1.6 - Low Coolant Level Sensor 1.7.4 OVERSPEED SHUTDOWN The engine control board receives AC frequency sig- nals from an engine run winding in the alternator. Should AC frequency exceed about 72 Hertz for three seconds or 75 Hertz instantaniously, the engine shuts down and the overspeed LED turns on.

Section 2 — Installation QUIETSOURCE™ Liquid-cooled 30 kW Generators NOTE: Port 1 is for NG only and Port 2 is for LP vapor only. No provision for dual fuel has been made. DANGER Serious injury or damage may occur if not configured properly.
Only qualified, competent installation contractors or electricians thoroughly familiar with applicable codes, standards and regulations should install this standby electric power system. The installation must comply strictly with all codes, standards and regula- tions pertaining to the installation. After the system has been installed, do nothing that might render the installation in noncompli- ance with such codes, standards and regulations.
Section 2 — Installation QUIETSOURCE™ Liquid-cooled 30 kW Generators Figure 2.1 – Basic Standby Electric System EMERGENCY CIRCUIT ISOLATION METHOD This prevents overloading the generator by keeping electrical loads below the wattage/amperage capacity of the generator. If the generator is powering only crit- ical loads, within the wattage/amperage capacity, dur- ing utility power outages, consider using the emer- gency circuit isolation method.
Setting switch two to OFF allows the control PCB to perform the ATS control functions. Control system interconnections consist of N1 and N2, and leads 23 and 194. Control system intercon- nection leads must be run in a conduit that is sepa- rate from the AC power leads.
Section 3 — Operation QUIETSOURCE™ Liquid-cooled 30 kW Generators When using maintenance-free batteries, it is not nec- essary to check the specific gravity or electrolyte level. Have these procedures performed at the intervals specified in Section 4, “Maintenance.” A negative ground system is used.
• The control board will NOT activate the transfer output. • The control board WILL monitor all engine condi- tions and shut down on all the faults listed in this document. Pos2 OFF — ATS Application • The control board will perform all of the automat- ic features listed in this document.
Section 3 — Operation QUIETSOURCE™ Liquid-cooled 30 kW Generators 3.2.6 SYSTEM READY LED The System Ready LED (green) has two main pro- poses. First, the LED will be ON when the AUTO/OFF/MANUAL switch is in the AUTO position, utility is present, and there are no system alarms. This ON state indicates the system is fully ready for automatic operation.
AUTOMATIC OPERATION To set the system for fully automatic operation, pro- ceed as follows: • Check that load circuits are connected to the utility power supply. • Set the AUTO/OFF/MANUAL switch to its AUTO position. • Set the generator main circuit breaker to its ON or CLOSED position.
Section 4 — Maintenance QUIETSOURCE™ Liquid-cooled 30 kW Generators COOLING SYSTEM Air intake and outlet openings in the generator com- partment must be open and unobstructed for contin- ued proper operation. This includes such obstruc- tions as high grass, weeds, brush, leaves and snow. Without sufficient cooling and ventilating air flow, the engine/generator quickly overheats, which causes it to shut down.
4.5.4 INSPECT COOLING SYSTEM • Inspect engine cooling system at least once each month. • Check hoses for damage, deterioration, leaks, etc. Correct any discrepancies found. • Check hose clamps for tightness. 4.5.5 CHECK ENGINE COOLANT LEVEL See “Checking Fluid Levels” in Section 4.4. 4.5.6 PERFORM VISUAL INSPECTION Complete a thorough visual inspection of the entire engine-generator monthly.
Section 4 — Maintenance QUIETSOURCE™ Liquid-cooled 30 kW Generators Figure 4.3 – Engine Air Cleaner See the “Service Schedule,” Section 6, for air cleaner maintenance. 4.5.12 SPARK PLUGS Reset the spark plug gap or replace the spark plugs as necessary. See Section 6. 1.
4.6.3 BATTERY MAINTENANCE The battery should be inspected per the “Service Schedule,” Section 6. The following procedure should be followed for inspection: 1. Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary. 2. Check the battery fluid level of unsealed batteries and, if necessary, fill with DISTILLED WATER ONLY.
Section 4 — Maintenance QUIETSOURCE™ Liquid-cooled 30 kW Generators SCHEDULED MAINTENANCE Following is a recommended maintenance schedule for Generac small standby and residential generator sets. The established intervals in the schedule are the maximum recommended when the unit is used in an average service application.
Maintenance Level 1 Tasks Recom- mended to be done monthly 1. Disable the unit from operating per the first page warning. 2. Check the engine oil level. Adjust as necessary. 3. Check the engine coolant level. Adjust as necessary. 4. Check the engine coolant thermal protection level.
Section 4 — Maintenance QUIETSOURCE™ Liquid-cooled 30 kW Generators Maintenance Level 1 Tasks Recom- mended to be done monthly 13. Initiate an automatic start and transfer of the unit to site load and exercise it for at least 1 hour looking for leaks, loose connections or components, and abnormal operating...
