
Any attempt to crank or start the engine before
it has been properly serviced with the recom-
mended oil may result in an engine failure.
1.14 COOLANT RECOMMENDATIONS
Use a mixture of half low silicate ethylene glycol base
anti-freeze and half deionized water. Cooling system
capacity is about 8 U.S. quarts (7.6 liters). Use only
deionized water and only low silicate anti-freeze. If
desired, add a high quality rust inhibitor to the rec-
ommended coolant mixture. When adding coolant,
always add the recommended 50-50 mixture.

Do not use any chromate base rust inhibitor
with ethylene glycol base anti-freeze or chro-
miumhydroxide (“green slime”) forms and will
cause overheating. Engines that have been oper-
ated with a chromate base rust inhibitor must be
chemically cleaned before adding ethylene glycol
base anti-freeze. Using any high silicate anti-
freeze boosters or additives will also cause over-
heating. DO NOT use any soluble oil inhibitor for
this equipment.
1.15 BEFORE INSTALLATION
Before installing this equipment, check the ratings
of both the generator and the transfer switch. Read
“Emergency Isolation Method” and “Total Circuit
Isolation Method” in the installation manual (Part No.
079699).
The generator’s rated wattage/amperage capacity
must be adequate to handle all electrical loads that
the unit will power. It may be necessary to group the
critical (essential) loads together and wire them into
a separate “emergency” distribution panel.
This generator can be installed in conjunction with a
“GTS” type transfer switch, if necessary (see Section
2.9).
The standard prepackaged transfer switch (ATS
mode) does not have sensing or controlling circuit
boards. Instead, the generator control console hous-
es a “Printed Circuit Board Assembly”, which con-
trols all phases of operation, including engine start
up and load transfer.
2.1 STANDBY GENERATOR
INSTALLATION
DANGER

Connecting this generator to an electrical system
normally supplied by an electric utility shall be
by means of a transfer switch, so as to isolate
the electric system from the utility distribution
system when the generator is operating. Failure
to isolate the electric system by these means
will result in damage to the generator and may
also result in injury or death to utility workers
due to backfeed of electrical energy.

If an open bottom is used, the engine-generator
must be installed over non-combustible materi-
als and should be located such that combustible
materials are not capable of accumulating under
the generator set.
Only qualified, competent installation contractors
or electricians thoroughly familiar with applicable
codes, standards and regulations should install this
standby electric power system. The installation must
comply strictly with all codes, standards and regula-
tions pertaining to the installation.

After the system has been installed, do nothing
that might render the installation in noncompli-
ance with such codes, standards and regulations.
NOTE:
For more information about the installation of a
standby system contact an Authorized Service
Dealer.
