A subbase may be used to increase the
unit height and aid in leveling the unit.
The subbase is shipped separately for
field installation. Slots and leveling
screws are provided on the subbase.
1. Remove the leveling legs provided
with the unit. See Figure 16.
2. Set the unit on the subbase and
fasten with 4-3/8” x 16’ x 1-1/2”
hex head cap screws.
NOTE: Hex
screws provided by installer. Pre-
drilled slots in the subbase flange
will line up with the weld nuts in
the bottom of the unit.
3. The bottom of the subbase has weld
nuts in four slots. Place the leveling
legs in those slots and level the unit.
