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
•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.
•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.
•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.
•Radio Frequency Emissions.A filter is
available for machines in installations
where floor space is shared with
equipment sensitive to radio frequency
emissions.
•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.
•Chemicals. Keep stainless steel surfaces
free of chemical residues.
•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
•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.
•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
•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.
•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.
•Compressed Air.For machines requiring
compressed air service, best performance
will be realized if air is provided at a
pressure of 80 – 100 psi (5.4 – 6.7 bar).
•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.
•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.
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.
