injections should always have a duration of at least 10 seconds. With shorter injection
times, fine adjustments are not possible, and variations in response times have an exagger-
ated effect on the quantity delivered.
� Select pumps or valves of the appropriate size to provide for longer injection times.
� If quantities of one chemical must vary greatly among formulas, use two pumps or
valves for that chemical.
� If the injection duration is controlled by the chemical supply system (from others),
then the injection duration programmed at the washer-extractor controller need only be
sufficient to ensure detection by the chemical system.

Should the operator be signalled when the chemical is desired?
The audible operator signal will not occur until the When to start
chemical injection decision is satisfied. The commanded chemi-
cal injection will not begin until the operator manually cancels the
signal.
0
No. A signal is not required with this chemical injection. Chemi-
cals will inject without operator intervention.
1
Yes. A signal is required with this chemical injection. The signal
will start when all conditions for the chemical (temperature and/or
level) are satisfied. The actual injection will begin only after the
signal is cancelled, as below.
During normal operation (formula running), this keystroke cancels
the operator signal and allows chemical injection to begin if this
decision is set to 1=Yes.

After programming the first chemical, the controller returns to the
first chemical decision to allow the programming of a second
chemical.
0
No additional chemical in this bath. The cursor advances to the
next decision.
3
Chemical 3 (or any other valid chemical number). Cursor advan-
ces to decision W for this chemical.

Select a drain type for this bath step. This decision controls
whether the drain valve opens or remains closed when this bath
step ends, and how the basket rotates (if at all) while the machine
is filling and draining. Some of the selections below are valid only
if the step following this bath is another bath step. For example,
programming this decision as 1=Two way wash speed is not al-
lowed before an extract step because the goods would not be
evenly distributed around the basket when the machine acceler-
ated to extract speed.
