IMPORTANT SAFETY INSTRUCTIONS Guardian Liquid-cooled 40 kW Generator ! 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 and potential operators of this equipment. ! ! SAVE THESE INSTRUCTIONS – This manual contains important instructions that should be followed during installation and maintenance of the generator and batteries.
Important Safety Instructions Guardian Liquid-cooled 40 kW Generator • 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. Reconnect that cable last. • Never use the generator or any of its parts as a step.
Section 1 — General Information Guardian Liquid-cooled 40 kW Generator 1.1 UNPACKING/INSPECTION After unpacking, carefully inspect the contents for damage. • This standby generator set has been factory installed in an all-weather, metal enclosure that is intended exclusively for outdoor installation. If this generator is used to power electrical load circuits normally powered by a utility power source, code requires to install a transfer switch.
Section 1 — General Information Guardian Liquid-cooled 40 kW Generator 1.6 MAIN CIRCUIT BREAKER The generator’s main circuit breaker is included with the unit as shipped from the factory. The breaker for each unit is described as follows: 1.
Section 1 — General Information Guardian Liquid-cooled 40 kW Generator 1.8.2 GENERATOR AND LOAD COMPATIBILITY The generator must be fully compatible with the rated voltage, number of phases and frequency of the connected electrical loads. The generator, connected electrical devices, or both, can be damaged if voltage, number of phases and frequency are not compatible.
Section 1 — General Information Guardian Liquid-cooled 40 kW Generator 1.10 ENGINE OIL RECOMMENDATIONS The unit has been filled with 15W-40 engine oil at the factory. Use a high-quality detergent oil classified “For Service CC, SD, SE or SF.” Detergent oils keep the engine cleaner and reduce carbon deposits.
Section 2 — Installation Guardian Liquid-cooled 40 kW Generator STANDBY GENERATOR INSTALLATION DANGER Connecting this generator to an electrical system normally supplied by an electric utility shall be by means of a transfer switch (such as the Generac “Pre-packaged” type transfer switch), so as to isolate the electric system from the utility distribution system when the generator is operating.
Section 2 — Installation Guardian Liquid-cooled 40 kW Generator Figure 2.1 – Basic Standby Electric System DANGER Do not connect the ground wire to any pipe that carries a flammable or explosive substance – FIRE or an EXPLOSION may result. Proper grounding helps protect personnel against electrical shock in the event of a ground fault condition in the generator or in connected electrical devices. In addition, grounding helps dissipate static electricity that often builds up in ungrounded devices.
Section 2 — Installation Guardian Liquid-cooled 40 kW Generator 2.7 BATTERY INSTALLATION 2.7.1 VENTED BATTERIES DANGER ! Standby generators installed with automatic transfer switches will crank and start automatically when NORMAL (UTILITY) source voltage is removed or is below an acceptable preset level.
Section 2 — Installation Guardian Liquid-cooled 40 kW Generator 2.8 PREPARATION BEFORE START-UP The instructions in this section assume that the standby generator has been properly installed, serviced, tested, adjusted and otherwise prepared for use by a competent, qualified installation contractor. Be sure to read the “Safety Rules” on Pages 2 and 3, as well as all other safety information in this manual, before attempting to operate this (and related) equipment. 2.8.
Section 3 — Operation Guardian Liquid-cooled 40 kW Generator 3.1 CONTROL CONSOLE COMPONENTS The components of a liquid-cooled generator control console (Figure 3.1) are as follows: Figure 3.1 – Control Console 3.1.5 HOURMETER This indicates the time the engine-generator has operated, in hours and tenths of hours. Use the hourmeter along with the periodic maintenance schedule for the generator set. 3.1.6 AUTO/OFF/MANUAL SWITCH See Section 3.2. 3.1.
Section 3 — Operation Guardian Liquid-cooled 40 kW Generator 3.2.2 “OFF” POSITION This switch position shuts down the engine. This position also prevents operation. 3.2.3 “MANUAL” POSITION Set the switch to MANUAL to crank and start the engine. Transfer to standby power will not automatically occur unless there is a utility failure. ! 3.3 With the switch set to AUTO, the engine may crank and start at any time without warning.
Section 4 — Maintenance Guardian Liquid-cooled 40 kW Generator NOTE: Figure 3.2 – Engine Block Heater OUTLET If the battery terminals are disconnected or the control panel fuse is removed, the exercise timer needs to be reset for automatic exercise operation. Figure 3.3 – “Set Exercise” Switch on Control Panel INLET Refer to applicable wiring diagram(s) and electrical schematic(s) at the back of this manual for wiring connections. 3.
Section 4 — Maintenance Guardian Liquid-cooled 40 kW Generator 4.2 CHANGING THE ENGINE OIL AND FILTER 4.2.1 ENGINE OIL RECOMMENDATIONS Use oil of API Service Class SG, SH or SJ. The recommended oil grade for the engine is SAE 15W-40. 5. Apply a light coating of clean engine oil to the seal of new oil filter. Install the filter and tighten by hand only. DO NOT OVERTIGHTEN. 6. Remove the oil fill cap (Figure 4.1). Add the recommended oil (see Section 4.2.1). DO NOT FILL ABOVE THE DIPSTICK “FULL” MARK.
Section 4 — Maintenance Guardian Liquid-cooled 40 kW Generator 4.4 SPARK PLUGS Reset the spark plug gap or replace the spark plugs as necessary. See Section 4.12. 1. Clean the area around the base of the spark plugs to keep dirt and debris out of the engine. Clean the plugs by scraping using a wire brush. Do not “blast” the spark plugs to clean. 2. Remove the spark plugs and check the condition. Replace the spark plugs if worn or if reuse is questionable. See the “Service Schedule,” Section 4.
Section 4 — Maintenance Guardian Liquid-cooled 40 kW Generator 4.7 OVERLOAD PROTECTION FOR ENGINE DC ELECTRICAL SYSTEM Engine cranking, start-up and running are controlled by a solid-state engine controller circuit board. Battery voltage is delivered to that circuit board via a 15-amp fuse. These overcurrent protection devices will open if the circuit is overloaded.
Section 4 — Maintenance Guardian Liquid-cooled 40 kW Generator 4.11 OUT OF SERVICE PROCEDURE 4.11.2 RETURN TO SERVICE 4.11.1 REMOVAL FROM SERVICE To return the unit to service after storage, proceed as follows: If the generator cannot exercise every seven days, and it is to be out of service longer than 90 days, prepare the generator for storage as follows: 1. Verify that UTILITY power is turned off to the transfer switch and that the AUTO/OFF/MANUAL switch is set to OFF. 2.
Section 4 — Maintenance Guardian Liquid-cooled 40 kW Generator 4.12 SERVICE SCHEDULE ATTENTION: It is recommended that all service work be performed by the nearest Generac/Guardian Authorized Dealer. SYSTEM/COMPONENT X = Action R = Replace/Adjust as Needed * = Notify Dealer if Repair is Needed.
