3. Slot-Type Internal Air Make-Up

Hoods provided with "Short-Cycle" type air make-up only are supplied with a slot which is designed to direct the air along the top of the hood and into the exhaust plenum inlet. The volume of air can be regulated through the use of a combination balancing damper and fire damper located on top of the air make-up plenum. [Refer to fig. 24]

G.Auto Wash

Plenum wash down is a feature of the Energy Aire Ventilator which eliminates the need to frequently clean the grease extraction area. The wash down cycle normally occurs immediately after the cooking period and does not occur while the fans are ON. A water/detergent mixture is sprayed from a series of nozzles to remove accumulated grease and grime which flows out through the drain. A vacuum breaker/check valve must be installed upstream of the detergent injection point [and a minimum of 6" higher than the ventilator inlet] to prevent detergent from backflowing into the building water supply. [Refer to fig. 14]. Hot water should be at 120οF and pressure must be between 20 psig and 40 psig flow. The duration of the wash down cycle is adjustable and will vary depending of length of cooking cycle, type of cooking equipment used, concentration of detergent, water pressure and temperature, among other considerations. See Sec. VI, b., "Setting the PAWS", for instructions.

**Note: See Page 28 cut sheet for detergent information.

H.Cold Water Mist [Optional]

To aid in extracting particulates from the exhausted air and to aid in cooling the exhaust, a cold water mist option is available. This is especially useful with charbroilers. Cold water mist is a fine spray within the

plenum area which runs whenever the fans are ON. This com- plements the baffle system on Energy Aire Systems and does not replace the wash down feature. Water pressure should be between 30-40 psig flow.

I.Lights

1.Surface Mounted - Incandescent

To replace the bulb unscrew the globe. Fixture will accept bulbs up to a maximum of 100 watts. Screw the bulb into the socket and then proceed to screw the globe tightly in position. Be sure that the inner silicone gasket is in place before installing the globe

2. Recessed - Incandescent

To replace the bulb, loosen screws which retain diffuser panel. Diffuser panel is attached to housing with a cable to prevent it from falling or becoming lost. Fixture will accept bulbs up to a maximum of 150 watts.

3. Recessed - Fluorescent

To replace bulbs, unscrew diffuser panel. The diffuser is attached to a housing with a cable to prevent it from falling or being lost. Two [2] bulbs are required for each fixture.

VIII. PERIODIC MAINTENANCE A.Baffle Filters

Filters should be removed and cleaned at least weekly, depending on hours of operation. Filters may be cleaned by soaking in a strong detergent solution, or running thru a dishwasher. When replacing, make sure filters and handles are running vertically, and filters are seated properly, refer to Sec. VII, A.1, pg. 15.

B.Modular Grease Extractors

Modules should be removed and cleaned at least weekly, depending on hours of operation. Modules may be cleaned with a brush and a strong detergent solution, or run thru the dishwasher. When replacing modules, make sure they are seated properly, refer to Sec. VII, B.1, pg. 16.

C.Grease Trough

Should be checked weekly for grease build up, and cleaned with strong detergent, if necessary.
