AVI HOOD INITIAL START-UP

All AVI 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. These variables make it necessary to have an authorized service techni-

cian verify operation and make field adjustments if needed. The following items must be checked

and verified to meet the specifications and requirements stated in this manual prior to the hood be-

ing commissioned:

 Correct fan rotation.

 Balanced make-up air.

The Initial Start-Up Checklist must be completed at time of installation, signed by the Cus-

tomer and returned to XLT Ovens to initiate Warranty Policy.
