Hydraulic Hold Down (not
shown)
Jet spray header throttle valves are properly sized and positioned to
hydraulically hold down light plastic cage and steel pans to the conveyor. By
setting the throttle valve to restrict flow to the lower header, the pressure
differential will allow a higher volume of water to push down on caging.
Wash, Rinse, and Final Rinse
Treatment Temperature
Guarantees (not shown)
An agent wash, recirculated rinse, or final rinse temperature guarantee may
be programmed to ensure that minimum treatment temperatures are
attained and maintained. Should the temperature guarantee set points not
be attained or maintained, the conveyer belt will temporarily stop until the
treatment solution reaches the set point temperature. The controls signal
the user if there are any variances.
Water Conservation (not
shown)
The hot tap final rinse water is sprayed through the jet system and collected
in the recirculated rinse tank. The water is used for the recirculated wash,
rinse and pre-wash for water and energy conservation.

MOST COMMON OPTIONS
Stainless Steel Treatment
Components
All components including valves, pump, and piping that come in contact with
the recirculating treatment solution are 304 stainless steel to provide system
life and durability
House Tap Water
Temperature Booster
An instantaneous steam to water heat exchanger is provided to raise the
house tap water supply temperature.
Steam and Water Pressure
Gauges
Pressure gauges are provided on the incoming steam and water lines to
monitor the facility utilities.
Automatic Self Cleaning
Debris Filter
The output of the wash pump is provided with a self cleaning debris screen
having perforations smaller than the spray jets’orifices to prevent plugged
jets. The debris filter is automatically controlled to filter the recirculated was
solution and to periodically back flush debris to the drain. The screen
element may be accessed without the use of tools.
Automatic Drain System Provides the capability to automatically drain the agent wash and
recirculated rinse tanks at the end of the processing period.
Drain Discharge Cool Down
Injection System
Cold tap water is automatically injected into the drain discharge to lower the
discharge temperature before entering into the building’s drain system.
Washer Interior Cleaning
and Descaling System
Provided in the interior of each tank are jets to wash the walls of the tank to
remove debris build up. When activated the control system automatically
drains the wash tank, refills the tank with fresh water and a descaling agent,
and activates the belt and pumps for a user programmable period of time,
automatically draining and flushing each tank. This system reduces or
eliminates the need to clean the tanks manually.
Automatic Conveyor Stop A photoelectric switch is located at the end of the discharge conveyor to
automatically stop the conveyor drive when an item reaches the end of the
conveyor. A second photo eye may be located at the end of a bedding
dispenser, if equipped, user may program cycle to stop at end of washer or
dispenser. A stopped conveyor condition is visually annunciated to the user
on the control screen.
Recorder/Printer Issues a printed record of all pertinent cycle data, including treatment
functions, temperature, time and date. A Take-Up Reel is provided to
retrieve and rewind the print-out onto a spool. See also: Appendix A:
Recorder/Printer.

GENERAL MACHINE DESCRIPTION
At the start of the processing period, the user activates the unit for
automatic operation by turning on the main disconnect switch. The unit
automatically goes through a self diagnostic test then fills with fresh water
and heats to programmed temperature.
The user at this time can press the start prompt and place the load to be
cleaned on the stainless steel flat wire. The unit will automatically proceed
through the treatment process and deliver the items at the unload end of the
machine.
Automatic Treatment Cycle The standard treatment cycle consists of a pre-wash, an agent wash, a
recirculated rinse, final rinse, and recirculated air dry. All wash and rinse
treatments are recirculated under pump pressure. The cycle, once
activated, is completely automatic. Additional cycle treatment phases are
available.
Treatment Schedule PRE-WASH
Hot water from the recirculated rinse tank is directed through the upper and
lower jet spray headers under pump pressure to remove gross debris. This
solution is not recirculated and is sent to drain.
AGENT WASH
Hot chemical solution, from the wash tank, is recirculated through the wash
jet spray headers under pump pressure and retained in the wash tank.
Wash temperature is progammable up to 190oF.
RECIRCULATED RINSE
Hot water from the rinse tank, is recirculated through the rinse jet spray
headers (top to bottom) under pump pressure and retained in the rinse tank.
Rinse temperature is programmable up to 190oF.
NON-RECIRCULATED FINAL RINSE
Hot tap water from house supply is heated by a steam heat exchanger and
directed through separate final rinse jet spray headers under house supply
pressure and retained in the rinse tank for the recirculated rinse and pre-
wash. Final rinse temperature is manually adjustable to 195oF.
RECIRCULATED AIR DRY (Optional)
Hot air is recirculated through a finned steam coil and directed through flat
air knives. The dryer temperature is manually adjustable. Moisture is
eliminated by exhausting a portion of the recirculated air to the facility
exhaust system.
