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 chromi-
umhydroxide (“green slime”) forms and will
cause overheating. Engines that have been
operated with a chromate base rust inhibitor
must be chemically cleaned before adding ethyl-
ene glycol base anti-freeze. Using any high sili-
cate anti-freeze boosters or additives will also
cause overheating. 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 Sections 2.5 and 2.6.
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
an engineered transfer switch, if necessary.
The standard prepackaged transfer switch does not
have sensing or controlling circuit boards. Instead,
the generator control console houses a “Printed
Circuit Board Assembly”, which controls all phases
of operation, including engine start up and load
transfer.
2.1 STANDBY GENERATOR
INSTALLATION
Connecting this generator to an electrical sys-
tem normally supplied by an electric utility
shall be by means of a transfer switch, so as to
isolate the electric system from the utility distri-
bution 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-genera-
tor must be installed over non-combustible
materials and should be located such that com-
bustible materials are not capable of accumu-
lating 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 regula-
tions.
NOTE:
For more information about the installation of a
standby system contact a dealer.
