Key To Symbols
The lightning flash and arrowhead within the
triangle is a warning sign indicating the presence of
dangerous voltage.
The exclamation point within the triangle is a
warning sign indicating important instructions
concerning the machine and possibly dangerous
conditions.
This warning symbol indicates the presence of
potentially dangerous drive mechanisms within the
machine. Guards should always be in place when
the machine is in operation.
This warning symbol indicates the presence of
possibly dangerous chemicals. Proper precautions
should be taken when handling corrosive or caustic
materials.
This warning symbol indicates the presence of hot
surfaces that could cause serious burns. Stainless
steel and steam lines can become extremely hot and
should not be touched.
This warning symbol indicates the presence of
possibly dangerous pinch-points. Moving
mechanical parts can crush and/or sever body parts.
Ensure that the machine is installed on a level
floor of sufficient strength and that the
recommended clearances for inspection and
maintenance are provided. Never allow the
inspection and maintenance space to be
blocked.
&$87,21
SW020
Never touch internal or external steam pipes,
connections, or components. These surfaces
can be extremely hot and will cause severe
burns. The steam must be turned off and the
pipe, connections, and components allowed to
cool before the pipe can be touched.

To provide personal safety and keep the machine in
proper working order, follow all maintenance and
safety procedures presented in this manual. If
questions regarding safety arise, contact the factory
immediately.
Use factory-authorized spare parts to avoid safety
hazards.
Operator Safety
To ensure the safety of machine operators, the
following maintenance checks must be performed
daily:
1. Prior to operating the machine, verify that all
warning signs are present and legible. Missing
or illegible signs must be replaced immediately.
Make certain that spares are available.
2. Check door interlock before starting operation
of the machine:
a. Attempt to start the machine with the door
open. The machine should not start with the
door open.
b. Close the door without locking it and
attempt to start the machine. The machine
should not start with the door unlocked.
c. Close and lock the door and start a cycle.
Attempt to open the door while the cycle is
in progress. The door should not open.
If the door lock and interlock are not
functioning properly, call a service technician.
3. Do not attempt to operate the machine if any of
the following conditions are present:
a. The door does not remain securely locked
during the entire cycle.
b. Excessively high water level is evident.
c. Machine is not connected to a properly
grounded circuit.
Do not bypass any safety devices in the machine.
NEVER insert hands or objects into basket
until it has completely stopped. Doing so could
result in serious injury.

Safe Operating Environment
Safe operation requires an appropriate operating
environment for both the operator and the machine.
If questions regarding safety arise, contact the
factory immediately.
Environmental Conditions
l Ambient Temperature.Water in the machine
will freeze at temperatures of 32° F (0° C) or
below.
Temperatures above 120° F (50° C) will result
in more frequent motor overheating and, in
some cases, malfunction or premature damage
to solid state devices that are used in some
models. Special cooling devices may be
necessary.
Water pressure switches are affected by
increases and decreases in temperature. Every
25° F (10° C) change in temperature will have a
1% effect on the water level.
l Humidity. Relative humidity above 90% may
cause the machine’s electronics or motors to
malfunction or may trip the ground fault
interrupter. Corrosion problems may occur on
some metal components in the machine.
If the relative humidity is below 30%, belts and
rubber hoses may eventually develop dry rot.
This condition can result in hose leaks, which
may cause safety hazards external to the
machine in conjunction with adjacent electrical
equipment.
l Ventilation. The need for make-up air openings
for such laundry room accessories as dryers,
ironers, water heaters, etc., must be evaluated
periodically. Louvers, screens, or other
separating devices may reduce the available air
opening significantly.
l Radio Frequency Emissions.A filter is
available for machines in installations where
floor space is shared with equipment sensitive
to radio frequency emissions.
l Elevation.If the machine is to be operated at
elevations of over 3,280 feet (1,000 meters)
above sea level, pay special attention to water
levels and electronic settings (particularly
temperature) or desired results may not be
achieved.
l Chemicals. Keep stainless steel surfaces free of
chemical residues.
l Water Damage.Do not spray the machine with
water. Short circuiting and serious damage may
result. Repair immediately all seepage due to
worn or damaged gaskets, etc.
Do not place volatile or flammable fluids in any
machine. Do not clean the machine with
volatile or flammable fluids such as acetone,
lacquer thinners, enamel reducers, carbon
tetrachloride, gasoline, benzene, naptha, etc.
Doing so could result in serious personal injury
and/or damage to the machine.

Safe Operating Environment
(Continued)
Machine Location
l Foundation. The concrete floor must be of
sufficient strength and thickness to handle the
floor loads generated by the high extract speeds
of the machine.
l Service/Maintenance Space.Provide sufficient
space to allow comfortable performance of
service procedures and routine preventive
maintenance.
This is especially important in connection with
machines equipped with an AC inverter drive.
Consult installation instructions for specific details.
Input and Output Services
l Water Pressure. Best performance will be
realized if water is provided at a pressure of
30 –85 psi (2.0 –5.7 bar). Although the
machine will function properly at lower
pressure, increased fill times will occur. Water
pressure higher than 100 psi (6.7 bar) may
result in damage to machine plumbing.
Component failure(s) and personal injury could
result.
l Steam Heat (Optional) Pressure.Best
performance will be realized if steam is
provided at a pressure of 30 –80 psi (2.0 –5.4
bar). Steam pressure higher than 125 psi (8.5
bar) may result in damage to steam components
and may cause personal injury.
For machines equipped with optional steam
heat, install piping in accordance with approved
commercial steam practices. Failure to install
the supplied steam filter may void the warranty.
l Drainage System.Provide drain lines or
troughs large enough to accommodate the total
number of gallons that could be dumped if all
machines on the site drained at the same time
from the highest attainable level. If troughs are
used, they should be covered to support light
foot traffic.
l Power. For personal safety and for proper
operation, the machine must be grounded in
accordance with state and local codes. The
ground connection must be to a proven earth
ground, not to conduit or water pipes. Do not
use fuses in place of the circuit breaker. An
easy-access cutoff switch should also be
provided.
Always disconnect power and water supplies before
a service technician performs any service
procedure. Where applicable, steam and/or
compressed air supplies should also be
disconnected before service is performed.
Replace all panels that are removed to perform
service and maintenance procedures. Do not
operate the machine with missing guards or
with broken or missing parts. Do not bypass
any safety devices.
&$87,21
SW019
Ensure that a ground wire from a proven earth
ground is connected to the ground lug near the
input power block on this machine. Without
proper grounding, personal injury from electric
shock could occur and machine malfunctions
may be evident.
