INSTALLATION
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.
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.
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 QT50, QT70,
QT100 - QT150.
• 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.
