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

Installation NOTE: If you have a Back Supply Fig. 1 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.

External Supply Plenum Installation The purpose of the external supply plenum is to provide make-up air to an exhaust hood to maintain the air balance in the space. The external supply plenum must be hung independent of the hood. Follow the instructions for hanging the following supply plenums: Horizontal, Air Curtain and Variable. See page 8 for Back Supply Plenum. If an external supply plenum is not provided, skip this section. Installation Instructions Support plenum from all hangers prov

Hanging the Hood with Back Supply Plenum Before hanging the hood according to the hood installation instructions, please check the following: 1. Make sure the back supply unit is properly secured, as described in steps 5 and 6, page 8. 2. Any filler panels should be attached to the hood before the hood installation. To hang the hood: 1. Lift the hood and position it so the top of the hood is even with the back supply (Fig. 13). This height should correspond to the UL hanging height of the

Duct Collar Installation Exhaust Ducts 1. If the exhaust duct has been factory mounted, skip this section. 2. The exhaust duct must be located within the shaded region of Fig. 20. Note dimensions. Dimension Y assumes a 3 in. (76.2 mm) integral airspace on the hood back. When no 3 in. (76.2 mm) integral airspace is present, Y=0 in. (0 mm). 3. Cut out appropriate size hole to match the duct collar provided. 4. The exhaust duct connection is to be a continuous liquid-tight weld. x HANGER BRACKE

Exhaust Air Balancing Baffles (EABB) This is a guide to assist in determining if multiple hoods on one fan can be balanced to have equal static pressure. For multiple hoods on one fan to achieve their designed exhaust flow, all of the hoods must have equal static pressure at their designed exhaust flow. The laws of physics force the static pressure for each branch of a duct system on one fan to always be equal. This will happen by the flow rate increasing in low static branches and decreasin

Balancing the Kitchen Exhaust System A. To determine the proper dining room air balance: 1. Refer to engineering drawings to determine total exhaust CFM from dining areas. (Exhaust fans, heating and air conditioning units, restrooms, etc.) 2. Determine the total CFM of make-up air supplied to dining area. 3. Subtract #1 from #2 above. If the result is a negative number, a negative pressure is present in the dining area. In this case, kitchen exhaust odors could be drawn from the kitchen to the

Measure the velocity of each location. A digital 2.75 in. (70 mm) rotating vane anemometer or equivalent Rotating Vane Anemometer is suggested. The center of the anemometer should be held 2 in. (50 mm) from the face of the filters as shown in Fig. 22. It is helpful 2 in. to make a bracket to keep the anemometer at the 2 in. (50 mm) Fig. 22 distance and parallel to the filter. Both squareness and distance are very important for accuracy. Calculate the average velocity for the filter.
