Standby Generator Sets

Installation

INSTALLATION

‹PRIOR TO INITIAL START-UP

Refer to the separate “Installation Guide QT Product Line” supplied with the unit.

PREPARATION BEFORE START-UP

The instructions in this section assume that the standby generator has been properly installed, ser- viced, tested, adjusted and otherwise prepared for use by a competent, qualified installation contractor. Be sure to read the “Safety Rules”, as well as all other safety information in this manual, before attempting to operate this (and related) equipment.

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 the “Maintenance” section and the “Service Schedule”.

‹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.

‹FUEL SYSTEM

Make sure the fuel supply system to the genera- tor (a) delivers the correct fuel at the correct pres- sure and (b) is properly purged and leak tested according to code. No fuel leakage is permitted. See “Specifications” for more information.

‹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” and “Engine Oil Recommendations”.

NOTE:

This engine is shipped from the manufacturer with “break-in” oil. This oil should be changed after 30 hours of operation.

Check the oil level in the generator gearbox (if so equipped) prior to initial use and at the intervals indicated by the “Service Schedule.” The recom- mended oil is SAE 90 gear lubricant.

Also, if the engine is equipped with a mechanical gov- ernor, make sure the governor is properly lubricated with clean engine oil.

8-1

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.

‹ENGINE COOLANT

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

‹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).

‹ELECTRICAL SYSTEM

Make sure the generator is properly connected to an approved earth ground.

Make sure the generator battery is fully charged, properly 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.

INITIAL INSPECTION FOR QT GENSET STARTUP

Inspect for the following.

•Freight Damage.

•Manuals present.

•Fluid Levels (Oil, coolant, battery, Gear Drive).

•Correct fuel piping.

•Correct muffler installation for external applica- tion.

•Adequate air flow, clearances and ventilation per installation drawings and applicable codes.

•Correct AC and DC wire size, connections and grounding. Control and communication wiring to/ from the transfer switch must be run in a separate conduit from the AC power leads.

•Battery charger connection to 120 VAC.

•Communication wires connected between transfer switch and generator (HTS only).

•Unit secured to pad.
