INSTALLATION
LIFTING
The basic blower is supplied with lifting lugs at each top corner of the unit. Attach lifting equipment only to
the lifting lugs.
LOCATION
Install the blower in well lit, clean and dry place with plenty of room for inspection and maintenance.
FOUNDATION
For permanent installations we recommend concrete foundations be provided, and the equipment should
be grouted to the concrete. It is necessary that a suitable base be used, such as a steel combination
base under blower and motor, or a separate sole plate under each. Before grouting, equipment must be
leveled, free of all strains, and anchored so no movement will occur during setting of grout. After grout
has completely hardened, a recheck is necessary to compensate for shrinkage, etc. If required, add
shims under blower feet after final tightening of foundation anchor bolts to remove strain from the blower
housing. Where jack screws or wedges are used during grouting, they must be backed off or removed
before final tightening of anchor bolts.
Where a concrete foundation is not feasible, care must be taken to insure that equipment is firmly
anchored to adequate structural members.
MOUNTING COFIGURATIONS
The blower flex-mounting design enables horizontal and vertical mounting configurations with top or
bottom hand, right or left hand shaft positioning. The units are discharge timed allowing rotation in only
one direction (refer to Figure 2-1, page 12 and Figure 2-2, page 13). If converting a blower from vertical
bottom hand drive to vertical top hand drive or vice versa, the oil slinger on each end must be moved to
the lower rotor.
