manual abstract
It enables users of pressure fryers and deep fryers to operate their fryer in a location without an externally-exhausted ventilation hood and wall-mounted fire suppression system. The exhaust hood is designed to accommodate fryers which hold up to a maximum of 85 pounds of oil (470 square inch vat area) and are supplied with 24 kW of power. Interconnection to the hood’s contactor box provides fire suppression interlock switching of the fryer’s power input. The three-stage filtration system removes oil particles, steam and condensation, and most cooking odors from the exhaust air. The ANSUL® Fire Suppression System actuates automatically if the temperature below the hood exceeds 165°F (74°C), or can be manually triggered by the operator. In either case, fryer operation will be disabled. A damper at the blower outlet will close automatically to restrict air flow to the fire. Safety interlocks disable operation of the fryer if (a) the fire suppression system is not charged and cocked; (b) one or more filters are missing or incorrectly installed; and (c) the exhaust blowers are not operating. Indicator lights aid troubleshooting by pinpointing open interlock switches. Hobart exhaust hoods are produced with quality workmanship and material. Proper installation, usage and maintenance of your exhaust hood will result in many years of satisfactory performance. It is suggested that you thoroughly read this entire manual and carefully follow all of the instructions provided. INSTALLATION Before installing, verify that the electrical service agrees with the specifications on the rating plate located on the left side of the hood by the ANSUL® manual pull. If the supply and equipment requirements do not agree, do not proceed with the installation. Contact Hobart Corporation immediately. UNPACKING Immediately after unpacking, check for possible shipping damage. If the exhaust hood is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery. Carefully unpack exhaust hood and place in a work-accessible area as near to its final installed position as possible. © HOBART CORPORATION, 2000 – 3 – Locate and identify the following components: 1.

Fig. 1 shows the long, welded pins (3 on the right and 3 on the left) against which the filters rest. Directly behind the pins on the left side are three shorter filter actuator switch pins which push in and out. Each filter must be placed so that it pushes its filter actuator switch pin in or your appliance will not operate. – 4 – Remove the plastic cover from the Charcoal Filter.
