Section 2 — Installation

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.

OTHER PUBLISHED STANDARDS

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, you must not do anything that might render the installation in noncompliance with such codes, standards and regulations.

NOTE:

For more information about the installation of a stand- by system, you can order Engine-Generator Standby Electric Power Systems Installer’s Guide and Reference Manual (part #046622) from your Generac Authorized Service Dealer.

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, you may need to consider using a windbreak to pro- tect 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.
