The VFD controller is adjusted at the factory to the values displayed in the chart below.
All XLT Hoods are functionally tested at the factory. Operation is verified, and adjust-
ments are made to ensure proper operation. However, field conditions are sometimes different
than factory conditions.
It is necessary to have an authorized service technician verify operation
and make field adjustments if needed.
The following items must be checked and verified to meet the specifications and require-
ments stated in this manual prior to the hood being commissioned:
Correct fan rotation
Balanced make-up air
The Hood Initial Start-Up Checklist, found at the end of this manual, must be completed
(both sides) at time of installation, signed by the Customer and returned to XLT and the Author-
ized Distributor to initiate Warranty Policy.
If the Start-Up Checklist is not filled out completely
and returned to XLT, the Warranty will not be honored.
