Transportation Recommendations
Use a suitable cart or equipment to carry the generator
set, including wooden pallet, to the installation site. Place
cardboard between cart and generator set to prevent any
damage or scratches to generator set.
Do not lift, carry, or move generator set by grasping
the louvers. Doing so may bend or damage the sheet
metal.
Suitable Mounting Surface
Select non-combustible base type as desired or as
required by local laws or codes. The generator set is typ-
ically placed on pea gravel, crushed stone, a concrete
pad, or a preformed pad.
