WARNING: BURN HAZARD

•
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.
3.2.5 Rinse 2
•
The
RINSE 2
indicator message display on control panel illuminates and the machine
continues to fill from the end of the rinse 1 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
indicator
message control panel also illuminates. When the fill solenoid closes, the
FILL
message
is extinguished.
•
The recirculation wash pump is activated and the final rinse water is pumped through the
piping, out the rotating arms and through the quicklock connection to the removable
header. The
rinse 2 timer
is also activated and the pump remains energized until the
timer times out. This step provides thorough final rinsing of the items being washed and
the inside of the cabinet. During Rinse 2, 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 2 timer has completed its time, the wash recirculation pump is deactivated
and the controller verifies whether to hold or drain the final rinse water. If the controls
have been set to retain the water, then the unit proceeds to the
exhaust step
of the
program.
•
If the controls have been set to drain the water, and the Rinse 2 timer 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.
•
When the drain delay timer has completed, then 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 rinse water from the sump to the sewer.
WARNING: FALL HAZARD
To prevent falls, keep floors dry. Promptly clean up any spills or drippage.
