Operating and Maintenance Manual
Scientek Washer Model SW-6000
Revision-3, Sept. 2007
3-7
3.2.4 Rinse 1
•
The
RINSE 1
indicator light display message on the control panel illuminates and the
machine continues to fill from the end of the wash flush drain.
•
The controller monitors the float and when the float rises, the controller closes the fill
solenoid. On units equipped with the
heat exchanger option
, the water is preheated to
180
°
F (82
°
C) prior to entering the unit. While the machine is filling, the
FILL
message
on the control panel also illuminates. When the fill solenoid closes, the
FILL
indicator
message is extinguished.
•
The recirculation wash pump is activated and the rinse water is pumped through the
piping, out the rotating spray arms and through the quicklock connection to the removable
header. The
rinse 1 timer
is also activated and the pump remains energized until the
timer times out. This step provides thorough removal and rinsing of detergent wash water
from the items being washed and the inside of the cabinet. During Rinse 1, the Aqua-
pulse 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.
•
When the rinse 1 timer has completed, 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.
•
When the drain delay timer has completed, 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 drain.
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 spray arms and header to drain.
•
When the gravity drain timer has completed, 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 its time, the drain valve closes and the fill
solenoid remains open for the next step in the cycle.
•
The
RINSE 1
indicator message, which has remained illuminated throughout this section,
is now deactivated.
