Installation, Preparation before start-up, Initial inspection for genset startup – LG 30kW User Manual
Refer to the separate “Installation Guide” 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”.
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
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” for
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”.
This engine is shipped from the manufacturer
with “break-in” oil. This oil should be changed
after 30 hours of operation.
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.
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.
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).
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
Battery charger must be connected to 120 VAC, 15
amp circuit to operate.
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 GENSET
Inspect for the following.
• Freight Damage.
• Manuals present.
• Fluid Levels (Oil, coolant, battery, Gear Drive).
• Correct fuel piping.
• 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.
