3.2. Determining Load Size
Putting
too much
linen into a properly designed laundry washer-extractor will not
overload
the
machine to its mechanical or electrical detriment if these guidelines are followed:
1. The goods consist of typical cotton and/or synthetic fabrics normally encountered in
commercial laundering operations.
2. The load is not so bulky as to prevent a reasonably balanced distribution prior to the onset of
extraction.
3. The extract speed has not been increased above the designed maximum.
4. The total number of intermediate and final extractions do not exceed the designed maximum
for the extract motor.
Thus, the
maximum soiled linen capacity
for any properly designed washer-extractor is
essentially limited by the amount of soiled goods that can actually be placed in the cylinder.
The maximum weight of soiled goods that a washer-extractor cylinder will accept depends on the
following factors:
• the internal volume of the cylinder (the space into which the goods can be placed), and
• the density (weight and bulkiness) of the specific goods
For example, many polyester-cotton fabrics have relatively low weights for their bulk so one
should rarely expect to be able to put in a published maximum capacity load of such fabrics. In
fact, published maximum capacities of machines based on the now generally accepted industry
standards will usually be achieved only with the highest density, closely woven fabrics and a
reasonable soil content.
The best load size depends on the size of the machine—plus the type of goods, soil content, and
wash quality desired. Since the latter factors vary considerably, prior experience and/or
experimentation generally yield the best results. Use these guidelines:
1. Overloading a washer-extractor will not increase production because longer wash formulas
and more rewash will be required.
2. Avoid underloads because the inevitable greater extraction imbalance will cause more extract
re-cycles and may stress the machine unnecessarily.

3.3. Using the Machine
The Milnor
®
electronic coin washer-extractor controller allows wash cycles to be started in two
ways:
• Section 3.3.1 describes how a paying customer operates the machine, including loading the
machine, selecting the desired wash cycle, and starting the machine by inserting coins and
pressing the
Start
button.
• Section 3.3.2 describes how laundry personnel can operate the machine without using coins
by setting the
Attendant
switch to the
Attendant
(horizontal) position.
Section 3.3.4 includes a brief overview of the error recovery process. Refer to Section 4.1. “Error
Codes” for more details on error recovery. Supplement 3 “Recycle Sequence to Reduce
Vibration During Extract” details the sequence of actions automatically commanded by the
control system if the vibration safety switch trips because of excessive vibration during an extract
step.
