DOOR LOCK
Prior to beginning a cycle, there is a door
lock routine of lock/unlock/relock; then cycle
begins. The door will remain locked until the
end of a cycle or approximately 2 minutes
after a power interruption.
NOTE: If power is interrupted prior to 2
minutes of operation the automatic door
unlocking mechanism may fail, and door will
remain locked until the power is restored or
the lock is manually opened by pulling down
on the manual release tab. (See page 4-16)
PRICING
After the door is opened following the
completion of a cycle, the display indicates the
cycle price (unless set for free operation). As
coins are dropped or debit inputs arrive, the
display will change to lead the user through
the initiation of a cycle.
FREE CYCLES
This is established by setting the cycle price to
zero. When this happens, ‘SELECT CYCLE’
will be displayed rather than a cycle price.
DEBIT CARD READY
This washer is debit card ‘cable’ ready. It
will accept a variety of debit card systems,
but does NOT come with a debit card reader.
Refer to the debit card reader manufacturer for
proper washer set-up. In models converted to
a Generation 1 debit card system, debit pulses
represent the equivalent of 1 coin (Coin 1).
NOTE: Requires a 60” communication Cable
to connect UIC to Card Reader mounted in a
metercase. Request this cable from the Card
Reader supplier.
DISPLAY
After the washer has been installed and
plugged in, the display will show ‘0 MINUTES’.
Once the washer has been plugged in and the
washer door opened and closed, the display
will show the price.
During a cycle the display will show the
approximate time remaining unless the
washer is going through a “Suds Removal
Routine.” During the routine the display will
alternate between the word “SudS” and the
time remaining in the routine. At the end of
the 5 minutes needed for this routine, the
display returns to the same time displayed
prior to entering it.
