FINAL RINSE: Fresh pressurized rinse water enters the machine through a standard “Y” strainer, solenoid valve, and approved vacuum breaker assembly and is plumbed to upper and lower final rinse arms located at the output end of the machine. A single row of fan jet nozzles are located on both rinse arms. Connection point is provided for rinse agent injection into the final rinse line by others. Total final rinse flow rate is 3.7 GPM.
DRAIN, OVERFLOW, AND MAKE-UP: The machine is designed to maintain appropriate wash and power rinse tank water levels at all times even at low pressures. The overflow system is designed to automati- cally skim the surface of the wash and power rinse tanks. Make-up water from the final rinse system replen- ishes the wash and power rinse water, maintains water levels as well as appropriate tank temperatures. Large levers located on the front panel of the machine operate valves that drain the machine completely.
PRESSURE REDUCING VALVE:
Factory installed on incoming water line to control water pressure.
Additional Standard Equipment:
•Vent cowls/splash shields with 4” x 16” openings covered with removable plates for connection to exhaust ducts when required.
•Flexible NSF approved strip curtains provided at the ends of the vent cowls as well as at the ends of the machine and sepa- rating the wash, power rinse, and final rinse sections.
•Extra large inspection doors located on front of machine for easy access and cleanability
•Safety door switches shut down machine should any door be opened during operation.
•Stainless steel front appearance panel.
•Positive low level water protection for wash and power rinse tank heat.
•Sealed dial type thermometers for the wash, power rinse and final rinse temperatures.
Optional Mandatory Equipment:
Wash Tank Heating Equipment (Choose One):
ELECTRIC: Low watt density 25 KW tubular heating elements mounted inside the tanks (15 KW wash and 10 KW power rinse) and easily removable from the outside. The heaters are protected by a stainless steel float sys- tem as well as high limit overload protection. Water tem- perature in the tanks is controlled and maintained by fast reacting thermostats which control the heating elements.
STEAM: Stainless steel coils are utilized rather than injectors so that contaminated steam being injected into the wash water is not an issue. Stainless steel tubular steam coils are mounted inside the wash and power rinse tanks below the optimum water level. The coils are protected by a stainless steel float system. An external steam “Y” strainer and high temperature steam solenoid regulates the flow of steam through the coils. Temperature in the tanks is controlled and maintained by fast reacting thermostats which control the operation of the steam solenoids. A float and thermostatic steam trap is provided and removes steam condensate from the steam coils which can either be plumbed to a drain or pumped back to the boiler if a condensate return system is available. Steam coils require a minimum of 10 PSIG flowing steam supply and a maximum of 20 PSIG. Install with a steam pressure regulator (by others) if steam supply exceeds 20 PSIG.
Optional Features and Accessories:
EXTERNAL ELECTRIC BOOSTER HEATER:
External 36 KW Hatco booster heater boosts incoming 140°F water to a minimum of 180°F for hi-temp sanitiz- ing rinse. Custom features include castone-lined tank, low water cutoff, pressure relief valve, as well as a pres- sure reducing valve. Unit is located next to the output end of the machine, completely preplumbed. Power to the booster heater requires a separate electrical connec- tion. Unless specified otherwise, electrical characteristics of the booster heater will be the same as that of the dishwasher. The booster heater is approximately 36 KW and is available in 208/240/480 voltages/3 phase only.
EXTERNAL 70°F RISE BOOSTER HEATER:
External 45 KW Hatco booster heater capable of boosting incoming 110°F water a minimum of 70 degrees to a minimum of 180°F for hi-temp sanitizing rinse. Unit is located next to the output end of the machine and comes completely preplumbed. Power to the booster heater requires a separate electrical connection. Unless speci- fied otherwise, electrical characteristics of the booster heater will be the same as that of the dishwasher. The booster heater is available in 208/240/480 voltages/3 phase only.
STEAM BOOSTER HEATER: Sized to be con- nected to a standard 140°F incoming water supply in order to insure 180-195°F hi-temp sanitizing final rinse requirements. Unit comes complete with steam “Y” strainer and high temperature steam solenoid as well as a steam pressure relief valve. Water temperature is con- trolled and maintained by a fast reacting thermostat which controls the operation of the steam solenoid. A float and thermostatic steam trap is provided and removes steam condensate from the coil which can
either be plumbed to a drain or pumped back to a boiler if a condensate return system is available. Must be installed with a steam pressure regulator (by others) if steam supply exceeds 20 PSIG.
TABLE LIMIT SWITCH: Factory wired to machine and mounted to the backsplash of the table in the field. Prevents damage to conveyor drive system, racks, and dishes due to racks backing up on the output end of the machine. Highly recommended for clean dishtables less than 10 feet in length.
VENT COWL COLLARS: Factory installed 4” x 16” x 7” high collars located on the vent cowls to allow easy connection to an external exhaust system including a standard “pant-leg” type exhaust duct. Includes adjustable and lockable damper flap for fine tuning exhaust system to remove appropriate CFM requirements.
50 CYCLE (HERTZ) ELECTRICAL
CHARACTERISTICS: Units are available in 50 HZ
in the following voltages: 208V/1 or 3PH, 230V/1 or 3PH, 380V/3PH, and 460V/3PH. Units operating at 50 HZ are not submitted for UL Listing.
SIDELOADER: Factory installed option on input end of conveyor machine. This feature allows the machine to be installed close to a corner and maximize dishroom space. The sideloader option is available in both the hooded and unhooded versions. See separate spec sheets for details.
EXHAUST VENT FAN CONTROL:
Automatically turns exhaust vent fan on when rack enters the machine. Delay timer also turns off the exhaust vent fan 5-10 seconds after rack exits machine when no other racks are being conveyed through the machine.
FLANGED FEET: Available for installations where permanent mounting to the floor is required. Fully adjustable for required height.
WATER HAMMER ARRESTOR: Installed
inside the supply line.
