Torit Backward Inclined Fan, TBI-3 through 30
8
Fan with Inlet Spool Piece Mounted to
Clean Air Outlet with Adapter
The following instructions are for a TBI fan being
mounted to a Donaldson Torit dust collector that has a
side mount adapter.
1. Apply sealer, furnished in the installation hardware
kit, around the clean air outlet opening of the
collector. Sealer should be applied in a Figure 8 type
pattern around each bolt hole so that inlet is sealed
from both the outside and the inside of the bolt hole.
2. Bolt the TBI fan to the adapter by inserting the
bolts on the TBI inlet into the appropriate holes
of the adapter. Install the nuts that came with the
fan. Be sure to position the discharge to be free of
obstructions and locate so that the motor’s electrical
box will be positioned for wiring convenience.
3. Inspect the installation prior to starting the fan.
Check for any loose items or debris that could be
drawn into the fan or dislodged by the air discharged
from the fan outlet. Check the interior of the fan as
well. Turn the wheel by hand to check for binding.
4. Complete the electrical connections in accordance
with NEC code and state and local codes. “Bump”
the starter to make sure the motor is rotating in
the proper direction. (Standard TBIs are clockwise
rotation as viewed from the motor endbell.)
5. Apply sealer on the inlet spool piece and re-attach
the TBI fan to the inlet spool piece. Be sure to
position the discharge to be free of obstructions
and locate so that the motor’s electrical box will be
positioned for wiring convenience.
6. Inspect the installation prior to starting the fan.
Check for any loose items or debris that could be
drawn into the fan or dislodged by the air discharged
from the fan outlet. Check the interior of the fan as
well. Turn the wheel by hand to check for binding.
7. Complete the electrical connections in accordance
with NEC code and state and local codes. “Bump”
the starter to make sure the motor is rotating in
the proper direction. (Standard TBIs are clockwise
rotation as viewed from the motor endbell.)
Motor Drain Hole Orientation
(Side Mount Fans)
Motor drain holes must be oriented downward to prevent
water accumulation in the motor and extend motor life.
