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
