4 Installation
4.1 Site Assessment and Preparation
Proper component location and site preparation have a very important impact on
completing a successful installation. The major components and sources of power
needed for installation include the following items:
Generator set
Transfer switch
Electrical utility
Fuel source
Accessories (may be required under certain conditions)
Generator Set Installation Suggestions and Guidelines
Locate the generator set on stable ground, not subject to flooding. Generator
set should not be installed where significant water runoff from a roof or
downspouts is present. Sump pump discharge should be routed away from the
generator set.
Locate and orient the generator set such that prevailing winds will carry exhaust
gases and fuel leaks away from the house or occupied areas.
This unit is to be installed so that the risk of contact by people is minimized.
The generator set must be located far enough away from any intake openings
to the structure, including furnace intake vents, or other similar intakes, to
prevent exhausted air from entering the structure. This includes roof soffits
which are ventilated, as well as vertically-discharging AC units. Generator set
exhaust must be ventilated away from the structure.
Picking a Location
WARNING
Exhaust gas is deadly. Install the generator set outdoors only. Locate the
generator set away from doors, windows, and other openings to the house
and where exhaust gases will disperse away from the house or occupied
areas.
NOTICE
All parts of the generator set enclosure must be at least 60 inches (1524 mm)
from any openings in walls of structures that may be occupied.
