Section 2 — Installation

40kW Liquid-cooled Generators

•Spilled electrolyte is to be washed down with an acid-neutralizing agent. A common practice is to use a solution of one pound (500 grams) bicarbon- ate of soda to one gallon (4 liters) of water. The bicarbonate of soda solution is to be added until the evidence of reaction (foaming) has ceased. The resulting liquid is to be flushed with water and the area dried.

Lead acid batteries present a risk of fire because they generate hydrogen gas. The fol- lowing procedure are to be followed:

•DO NOT SMOKE when near batteries,

•DO NOT cause flame or spark in battery area, and

•Discharge static electricity from body before touch- ing batteries by first touching a grounded metal surface.

Servicing of batteries is to be performed or super- vised by personnel knowledgeable of batteries and the required precautions. Keep unauthorized person- nel away from batteries.

The recommended battery is Group 27F, 12V nega- tive ground, 700 CCA/90 AH minimum capacity. All batteries must be at 100 percent state-of-charge before they are installed on the generator.

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. Battery connections are shown on the wiring diagrams. Make sure all batter- ies are correctly connected and terminals are tight. Observe battery polarity when connecting batteries to the generator set.

NOTE:

Damage will result if the battery connections are made in reverse.

2.11 PREPARATION BEFORE START-UP

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

‹2.11.2 TRANSFER SWITCH

If this generator is used to supply power to any elec- trical system normally powered by an electric utility, the National Electrical Code requires that a transfer switch be installed. The transfer switch prevents elec- trical backfeed between two different electrical sys- tems (for additional information, see the applicable transfer switch manual for this unit). The transfer switch, as well as the generator and other standby components, must be properly located and mounted in strict compliance with applicable codes, standards and regulations.

‹2.11.3 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 “Specifications” (Section 1.10) for more information.

‹2.11.4 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 “Specifications” (Section 1.10) and “Engine Oil Recommendations” (Section 1.14).

NOTE:

This engine is shipped from the manufacturer with 5W-20 oil. This oil should be changed after 30 hours of operation.

The instructions in this section assume that the standby generator has been properly installed, serv- iced, 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) equip- ment.

‹2.11.1 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 quantities of engine fluids (oil, coolant, fuel, etc.) may result in an engine failure.

‹2.11.5 ENGINE COOLANT

Have the engine cooling system properly filled with the recommended coolant mixture. Check the system for leaks and other problems. See “Specifications” (Section 1.10) and “Coolant” (Section 1.15).

‹2.11.6 BELT TENSION

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 approximately 22 pounds (10 kg), applied midway between pulleys, deflects the belt about 3/8- to 5/8- inch (10 to 16 mm).

‹2.11.7 ELECTRICAL SYSTEM

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