Section 2 — Installation

Guardian Liquid-cooled 40 kW Generator

2.8 PREPARATION BEFORE START-UP

‹ 2.8.5 BELT TENSION

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 safe- ty information in this manual, before attempting to oper- ate this (and related) equipment.

Check the engine fan belt tension and condition prior to placing the unit into service and at recommended intervals. Belt tension is correct when a force of approx- imately 22 pounds (10 kg), applied midway between pulleys, deflects the belt about 3/8- to 5/8-inch (10 to 16 mm).

‹2.8.1 PRIOR TO INITIAL START-UP

Prior to initially starting the generator, it must be

!properly prepared for use. Any attempt to crank or start the engine before it has been properly serviced with the recommended types and quanti- ties of engine fluids (oil, coolant, fuel, etc.) may result in an engine failure.

Before starting the generator for the first time, the installer must complete the following procedures. For follow-up maintenance information and/or service inter- vals, please refer to Section 4, “Maintenance.”

‹2.8.2 FUEL SYSTEM

Make sure the fuel supply system to the generator (a) delivers the correct fuel at the correct pressure and (b) is properly purged and leak tested according to code. No fuel leakage is permitted. See Section 1.8, “Specifications”, for more information.

‹2.8.6 ELECTRICAL SYSTEM

Make sure the generator is properly connected to an approved earth ground and/or ground rod.

Make sure the generator battery is fully charged, proper- ly installed and interconnected, and ready for use.

Check to ensure that there are no loose electrical con- nections. Restrain any loose wires to keep them clear of any moving generator set components.

‹2.8.7 RODENT PROTECTION

Make sure the four 3-inch diameter cap plugs (part # 0A8785) are properly installed in the tie-down holes in the side rails of the unit’s base frame (Figure 2.3). The cap plugs are shipped in a plastic bag located in the lower connection box. These plugs are needed to pre- vent rodents from accessing the interior of the genera- tor set. On acoustic units, cap plugs also are needed to stay within noise specification limits.

‹2.8.3 GENERATOR SET LUBRICATION

Check the engine crankcase oil level before operating and add oil to the proper level – the dipstick “FULL” mark. Never operate the engine with the oil level below the dipstick “ADD” mark. See Section 1.8, “Specifications” and Section 1.10, “Engine Oil Recommendations”.

NOTE:

This engine is shipped from the manufacturer with SAE 15W-40 oil. This oil should be changed after 30 hours of operation.

‹2.8.4 ENGINE COOLANT

Have the engine cooling system properly filled with the recommended coolant mixture. Check the system for leaks and other problems. See Section 1.8, “Specifications” and Section 1.11, “Coolant”.
