General Information
SITE PREPARATION AND GENERATOR
PLACEMENT
1. Locate the mounting area as close as possible to the transfer
switch and fuel supply.
Leave adequate room around the area for service access
(check local code), and place high enough to keep rising
water from reaching the generator.
Choose an open space that will provide adequate and
unobstructed airflow (see the "Location" section in the
Owner's Manual).
2. Place the unit so air vents won't become clogged with leaves,
grass, snow or debris. Make sure exhaust fumes will not enter
the building through eaves, windows, ventilation fans or other
air intakes.
Dig a rectangular area approximately five inches deep and
about six inches longer and wider than the footprint of the
generator. Cover with polyurethane film and fill with pea gravel
or crushed stone. Compact and level the stone. A concrete
pad can be poured if desired.

3. Inspect the generator for shipping damage and if necessary,
file a claim with the shipper.
Remove the bands holding the generator to the wooden pallet.
4. Make sure the lifting equipment to be used has sufficient
capacity to safely handle the weight of the generator.
Use nylon lifting straps and connect them to the lifting eyes
on each corner of the base frame to avoid damaging the
enclosure.
5. Set the generator onto the pad so that the gravel bed extends
beyond the generator on all sides.
Make sure the generator is level within ½ inch.
6. The engine generator is to be grounded in accordance with
the NEC and local electrical codes.
