Operation Section 3: Operation Site Prep Verification Generator Enclosure The generator must be installed so that airflow into and out of the generator is not impeded. Verify that all shrubs or tall grasses within 3 ft (0.91 m) of the intake and discharge louvers on the sides of the enclosure have been removed. Install the generator on high ground where water levels will not rise and endanger it. This unit should not operate in or be subjected to standing water.
Operation Intake Side Panel Removal 3. Lift the intake panel up and away from the generator. See Figure 3-2. The intake side panel (A) must be removed to access the battery compartment, fuel regulator, and sediment trap. NOTE: Always lift the intake side panel straight up before pulling away from enclosure. Do not pull the panel away from the enclosure before lifting up (D). 1. Raise the lid and remove the front panel. 2.
Operation Control Panel Interface Interface Menu Displays See Figure 3-5. The control panel interface (A) is located under the lid of the enclosure. Verify that both the left and right side locks are unlocked before attempting to lift the lid of the enclosure. Open the lid as directed in Opening the Lid. The LCD Panel Feature HOME page Default page that is displayed if no buttons are pressed for 60 seconds. Normally shows current status message and the current date and time.

Operation Setting the Exercise Timer This generator is equipped with a configurable exercise timer. Configuration can be performed directly at the control panel or though the Mobile Link™ application. There are two settings for the exercise timer: The exercise timer must be reset if the 7.5 amp fuse is removed.
Operation Manual Transfer Operation DANGER 7. Set the MLCB (generator disconnect) to ON (CLOSED). The standby power source now powers the loads. Electrocution. Do not manually transfer under load. Disconnect transfer switch from all power sources prior to manual transfer. Failure to do so will result in death or serious injury, and equipment damage. (000132) Prior to automatic operation, manually exercise the transfer switch to verify that there is no interference with proper operation of the mechanism.
Operation Transfer to Utility Power Source When utility power has been restored, transfer to utility source and shut down the generator. Proceed as follows to manually transfer to utility power and shut down the generator: 1. Set the MLCB (generator disconnect) to OFF (OPEN). 2. Run engine for two minutes at no-load to stabilize the internal temperature. 3. Press the control panel OFF button. The engine will shut down. 4. Verify that utility power supply to the transfer switch is turned off. 5.
Operation Cold Smart Start The Cold Smart Start feature is enabled at the factory, but can be disabled in the EDIT menu. The generator will monitor ambient temperature when Cold Smart Start is enabled. The warm-up delay will be adjusted based on prevailing conditions. If the ambient temperature is below a fixed temperature (based on model) upon startup in AUTO mode, the generator will warm up for 30 seconds. This allows the engine to warm before a load is applied.
