Upon receiving the equipment, check for both obvious and hidden damage. If damage is found, record all
necessary information on the bill of lading and file a claim with the final carrier. Check to be sure that all parts of
the shipment, including accessories, are accounted for.
STORAGE
If a kitchen hood must be stored prior to installation it must be protected from dirt and moisture. Indoor storage
is recommended. For outdoor storage, cover the hood with a tarp to keep it clean, dry, and protected from UV
(Ultra Violet) Radiation damage.
Improper storage which results in damage to the unit will void the warranty.
Hood weight is determined using a simple formula. Select the figures provided in columns A and B (see tables)
from the three respective categories—Hood Width, Filter Type and Hood Height—based on the hood received.
Total the three numbers in column A and the three numbers in column B. Place the sum for column A and the
sum for column B in the Hood Weight equation where shown and solve for the total Hood Weight.

NOTE: If you have a Back Supply
Plenum, this must be installed before
the hood. Please see page 8 now.
Prior to installation, check with local
authorities having jurisdiction on
clearances to combustible surfaces.
With the hood still inside its packing
crate, position the unit beneath its
installation location.
Carefully remove the packing crate.
Place some protective material on
the floor next to the crate to avoid
damaging the hood as it is tipped on its side (Fig. 1). Tip the hood carefully onto the protective
material. If you have filler panels, see Fig. 2 below. If you have integral filler panels, no additional
installation is needed.
