cylinder clockwise for four seconds at wash speed, then to accelerate to drain speed. A few sec-
onds after the cylinder reaches drain speed, the drain opens. The next step begins after the fixed
drain time and coast time expire. Coast time is not counted if the next step is an extract.
01=Hot soak Use hot soaks to maximize the activity of the injected chemicals when there is lit-
tle or no chance of stains being set by the high temperature. Temperatures above 120 degrees
Fahrenheit (49 degrees Celsius) usually make the removal of protein-based soils more
difficult.
02=Cold soak Use cold soak steps for goods that contain protein stains. The low temperature is
usually less effective than higher temperatures at activating certain chemicals, but the chance
of setting stains is much lower.
03=Split soak If the temperature of incoming hot water alone is higher than 120 degrees Fah-
renheit (49 degrees Celsius), soaking with both hot and cold water simultaneously will re-
move more soil than a cold flush. A split soak is also less likely to set protein stains than a hot
soak if the temperature of the split fill is consistently lower than 120 degrees Fahrenheit.

A flush is usually used early in a formula, prior to bleaching, to dilute and remove debris and
loose soil before chemicals are added. Flushes are also used to raise or lower the temperature of
the goods. Machines with the E-P Express
®
controller conduct all flushes at high water level
with the programmed waters (hot, cold, or split). Any chemicals may be injected, although this is
not common.
For any flush operation on the E-P Express
®
controller, the step timer begins counting when high
level is achieved and continues for the programmed time. The cylinder reverses at wash speed
while the step timer is counting down. When the step time expires, the controller commands the
motor to turn the cylinder clockwise for four seconds at wash speed, then to accelerate to drain
speed. A few seconds after the cylinder reaches drain speed, the drain opens. The next step begins
after the fixed drain time and coast time expire. Coast time is not counted if the step about to be-
gin is an extract.
04=Hot flush Use hot flushes to remove the maximum amount of debris and loose soil when
there is little or no chance of stains being set by the high temperature. Temperatures above
120 degrees Fahrenheit (49 degrees Celsius) usually make the removal of protein-based soils
more difficult.
05=Cold flush Use one or more cold flush steps to remove debris and loose soil from goods
that might contain protein stains before adding detergent. The low temperature is likely to be
less effective than higher temperatures at removing certain types of soil, but the chance of set-
ting stains is much lower.
06=Split flush If the temperature of incoming hot water is higher than 120 degrees Fahrenheit
(49 degrees Celsius), flushing with both hot and cold water simultaneously will remove more
soil than a cold flush. A split flush is also less likely to set protein stains than a hot flush if the
temperature of the split fill is consistently lower than 120 degrees Fahrenheit.
2.3.3.6.1.4 Wash (TT=07, 08, or 09)

Wash steps include break, suds, bleach suds, and carryover operations, and occur after the final
flush if one or more flushes are used. All wash steps programmed with this controller use low
water level. The first step to introduce chemicals to the machine cylinder is usually called a break
