Receiving and Handling

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 Weights

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.

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.

Hood Installation Overview

If a Back Supply Plenum is provided, install first. Before raising hood, insert 1/2 in. (12.7 mm) diameter threaded rod (by others) into hanger brackets on hood top. Check the engineering drawings or UL label located on the inside of the hood for proper hood height above finished floor. Install filler panels if needed. Raise and hang hood from adequate roof or ceiling supports and secure mounting flange to the wall using lag bolts, or fasten to the Back Supply Plenum if provided. All hanger brackets must be used and the hood must be properly supported while lifting to prevent damage or distortion to the hood. The hood must be hung level to operate properly. After hood is secured, make the exhaust duct connections. The fire system distributer must be contacted at this time. After the fire system has been installed, mount the enclosures, then the supply plenums. If a Horizontal Supply Plenum is provided, it should be installed according to the external supply plenum installation section found on page 7. The hood and accessories are now installed. Finally, make the electrical connections from switches to fans and complete the fire system circuits as required by the job specification.

Rear Filler Panel Installation Instructions

Rear filler panels may be shipped loose for field installaton or are integral to the hood. If fillers are integral to hood, skip this section.

1. Uncrate the hood and lay it on the floor with protective material between the hood and the floor.

2. Bolt the filler panels together with 5/16 in. bolts from the hardware package.

3. Position the filler panels on the hood, and tackweld them to the hood back.

4. To allow for ease of cleaning, caulk the external seams with NSF Approved silicone caulk (GE SCS1009, or its equivalent). The caulk is not provided.
