SPECIFICATIONS (Continued):
■HOSE AND REEL: (Optional) A spring loaded self coiling hose reel with 40 feet of high pressure hose with quick opening valve spray nozzle, conveniently mounted under table, used for table clean up or scraping dishes at soiled table section.
■BLOWER-DRYER (Optional Equipment)
DESIGN: To promote rapid drying of tableware and trays by forced circulation of high velocity heated air through the unloading section of Hobart FastRack automatic dishwashing system. Unit is built in straight section only. Blower-dryer covers 5 foot, 6 inches length of straight section to provide adequate drying area.
Heavy-duty squirrel cage type industrial fan draws room air through two 22" x 21" steam heated finned-type heat exchangers and large area ducting. (Optional electri- cally heated unit also available.) Heated air directed downward to drying area through rectangular orifice covering full width of conveyor. Baffles below conveyor redirect air upward within drying area.
Any object which will pass through the machine will be handled at the dryer area without necessity of readjusting blower orifice upward or downward.
CONSTRUCTION: All sheet metal construction is
16 gauge stainless steel, heliarc-welded and bolted. Large sliding inspection door provides access to dryer section at rectangular orifice area. Vent is 4" x 22" inside dimension and contains a locking type control damper. Vent stack rises at entrance end of dryer chamber for connection to dishroom exhaust stack. Motor mounted to permit “V” belt adjustment.
Stainless steel wrap-around encloses entire external component assembly, consisting of both steam coils, vent stack, motor and blower. Adds approximately 211⁄2" to height of machine.
STEAM COILS: Two double row heavy-duty high efficiency finned tube type heat exchangers set in tan- dem. Copper tubes and aluminum fins with galvanized steel frame. 11⁄2" female I.P.S. brass steam connection and 3⁄4" I.P.S. brass condensate return connection for each coil. Steam requirements are 110 pounds per hour at 20 P.S.I. or about 4.5 boiler H.P. Maximum allowable steam pressure is 25 P.S.I.
ELECTRIC HEAT: 12 - 3500 watt Incoloy electric heaters are used for a total of 42 KW heating capacity. Thermostatic control and separate over temperature protection are standard. Electrical specifications are 208/60/3, 240/60/3, and 480/60/3.
BLOWER: Industrial fan-type with squirrel cage-type wheel. Wheel shaft supported by two heavy-duty ball bearings. Housing of welded construction throughout.
2 H.P. Blower “V” belt driven, delivering 1384 CFM at 2200 FPM velocity. Exhaust requirement is 1200 to 1400 CFM.
Motor: 2 H.P. grease packed ball bearings, splash- proof enclosure, ventilated design. Furnished only in three-phase electrical specifications of the basic C-Line-A Model in 200-240/60 and 400-480/60. Above 250 volts, the controller circuit operates on reduced voltage supplied by the transformer on the dishwasher.
■PREWASH TEMPERATURE CONTROL: Control of prewash tank temperature is accomplished by adding cold water automatically through jet-type fill with suds trap and airbreak or vacuum breaker. The control components are installed on the prewash unit and consists of a thermostat, easy-open line strainer and solenoid valve. Prewash temperature control is required on units with RS or PW prewash when a Blower-Dryer is specified.
■AUXILIARY VENTING: An extended hood with a 4" x 16" vent opening can be mounted on the entrance or exit end of the warewasher. If a prewash in the curve is specified, a 4" x 16" vent opening is standard equipment but can be covered if desired.
■VAPOR CONDENSER OPTION: Eliminates the need of overhead watertight ducting and performs the neces- sary exhaust function from the dishmachine. Condenser is mounted over vent at discharge end of machine. On larger machines, two condensers may be used – one at each end. Not recommended where temperature of tap water exceeds 55°F. Refer to separate Condenser Spec. Sheet Form F-8102 for more complete details on condenser selection. Condenser is not a make-up air unit nor should it be used as a source of supply for make-up air.
If the optional Hobart Condenser is not specified, condensation-tight (water-tight) forced exhaust system to the outside air is necessary to carry off the humidity- laden drying air and thus maintain desirable working conditions within the dish room. Such exhaust system to be supplied by the user or general building contrac- tor at time of installation.
■SPECIAL NOTE: These specifications cover the dishwashing machine, rack transport system and over-shelving only. Supporting equipment such as soiled dish holding shelves, carts, rack dollies, silverware containers, silver sorting tables, soak sinks, self-leveling dispensers and other related equipment must be furnished by others to complete the warewashing system.
■SHIPMENT AND ASSEMBLY: System shipped in sections. Installation and connection of all utilities to be supervised by a factory trained, Hobart Service Technician.
Optional features in this specification sheet are available at extra cost.
