SECTION 2 - START-UP & OPERATION (CONTINUED)
Innergy Tech®
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 loosened 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 positioning
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 leakage 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 electrical
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 direction. If the
wheel is turning backward, reverse the motor rotation.
