Operating and Maintenance Manual
Scientek Washer Model SW-6000
Revision-3, Sept. 2007
3-4
control valves sequentially turn on and off the flow of circulating water to the left and
right side spray arms, and (if so equipped) the quicklock connection.
•
If the washer is equipped with a detergent neutralization system, and the detergent wash
timer has completed, the
detergent neutralizer pump timer
is initialized. This energizes
the detergent neutralizer pump and the
NEUTRALIZER
indicator is displayed and
dispenses neutralizer into the unit. The wash recirculation pump remains on during this
time. When the detergent neutralizer pump timer has completed, the neutralizer pump is
de-energized, the
NEUTRALIZER
display is deactivated and the
detergent neutralizer
wash timer
is initialized. During this time, the wash recirculation pump and Aqua-pulse
system is active in order to provide complete mixing of the neutralizer and detergent.
•
When the detergent wash timer (or detergent neutralizer wash timer, if installed) has
completed its time, the
drain delay timer
is initiated. During the drain delay, all the
Aqua-pulse valves are left open and the water is allowed to flow out of the spray arms
back to the sump. At the end of the drain delay, the Aqua-pulse valves are closed and
the
power drain timer
is initiated. During the power drain, the drain line valve opens
and the wash pump is energized. This forces the bulk of the wash water from the sump to
the sewer.
WARNING: FALL HAZARD
To prevent falls, keep floors dry. Promptly clean up any spills or drippage.
•
When the power drain timer has completed, the gravity drain timer is initiated. During the
gravity drain, the wash pump is deactivated and the drain valve remains open. This allows
any residual wash water in the sump, rotating arms and manifold to drain.
•
When the gravity drain timer has completed its time, the
flush drain timer
is initiated.
During the flush drain, the drain line valve remains open and the fill solenoid is opened.
This flushes the sump and drain line, ensuring the complete removal of any remaining
wash residue.
•
When the flush drain timer has completed, the drain valve closes and the fill solenoid
remains open for the next step in the cycle.
The
WASH
indicator display, which has remained illuminated throughout this section, is now
deactivated.
WARNING: BURN HAZARD
•
Doors, washer interior and washed wares may be hot.
•
Hot water/steam may be sprayed through door opening if door is
opened too soon - press STOP button and wait until water flow stops
before opening door.
Wear gloves and face protection.
