If an open bottom is used, the engine-generator is
to be installed over non-combustible materials
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 regulations per-
taining 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 stand-
by system, order Engine-Generator Standby Electric
Power Systems Installer’s Guide and Reference
Manual (part #046622) from the Generac Authorized

GENERATOR LOCATION
Install the generator set, in its protective enclosure out-
doors, where adequate cooling and ventilating air
always is available. Consider these factors:
• Install the unit where air inlet and outlet openings
will not become obstructed by leaves, grass, snow,
etc. If prevailing winds will cause blowing or drifting,
consider using a windbreak to protect the unit.
Install the generator on high ground where water lev-
els will not rise and endanger it.
Allow sufficient room on all sides of the generator for
maintenance and servicing. A good rule is to allow 3
feet of space on all sides.
Where strong prevailing winds blow from one direc-
tion, face the generator air inlet openings into the pre-
vailing winds.
Install the generator as close as possible to the trans-
fer switch. This reduces the length of wiring and con-
duit.
Install the generator as close as possible to the fuel
supply, to reduce the length of piping. HOWEVER,
REMEMBER THAT LAWS OR CODES MAY REGU-
LATE THE DISTANCE.

Guardian Liquid-cooled 15 kW, 20 kW and 25 kW Generators
STANDBY GENERATOR INSTALLATION
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.
