Section 2 — Installation

40kW Liquid-cooled Generators

If an open bottom is used, the engine-generator is to 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.

2.2GENERATOR LOCATION

Install the generator set, in its protective enclosure outdoors, where adequate cooling and ventilating air always is available. Consider these factors:

•Install the unit where air inlet and outlet open- ings 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 levels will not rise and endanger it.

•This genset must be installed on a level surface. The base frame must be level within 1/2 inch all around.

•Allow sufficient room on all sides of the generator for maintenance and servicing. A good rule is to allow five feet of space on all sides.

•Where strong prevailing winds blow from one direction, face the generator air inlet openings into the prevailing winds.

•Install the generator as close as possible to the transfer switch. This reduces the length of wiring and conduit.

•Install the generator as close as possible to the fuel supply, to reduce the length of piping.

HOWEVER, REMEMBER THAT LAWS OR CODES MAY REGULATE THE DISTANCE.

2.3GENERATOR MOUNTING AND

SUPPORT

Retain the generator compartment to a concrete slab with 1/4-inch masonry type anchor bolts. Be sure the bolts are long enough to retain the compartment. The slab should be at least six inches thick and should extend beyond the enclosure to a distance of at least three inches on all sides. See "Mounting Dimensions" for generator major dimensions.
