Start-Up Procedure
1. Make sure all bearing bolts and set screws are
tight. A special seal lacquer is factory applied.
This is a visual aid that will warn you if the pillow
block bolts or the bearings set screws have loos-
ened over time or during transport. A seal without
cracks is the indication that bolts and screws have
not loosened.
2. Be sure to use all lifting eye bolts when position-
ing energy recovery wheel into unit or ducting
location, and that weight is evenly distributed. If
the eye bolts need to be removed, bolts or plugs
should replace them in order to avoid any air leak-
age from these holes (required with top, bottom
and side galvanized plate option only).
3. Grease both pillow block bearings on the wheel,
using a NLGI grade 2 consistency, mineral oil
lithium or lithium complex base grease.
4. Before start-up, make sure the wheel turns by
hand and does not bind. All contact between the
seals and media should be verified and the seals
adjusted if needed.
5. Visually inspect the wheel to ensure it is centered
and does not tilt. If there is any indication of a
problem, call Innergy tech at 1-800-203-9015.
6. Does the power supply match the supply required
by the electrical equipment? If not, the electrical
equipment or the power supply must be changed.
The wheel identification tag located near the elec-
trical input gives the proper voltage to use.
Check the drive motor by bump starting it. Check the
wheel rotation to ensure it is turning in the correct di-
rection. If the wheel is turning backward, reverse the
motor rotation.
