Pressure Reducing Valve - Jackson Vision Series AJ-64 Product Manual

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.
