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.
•
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.
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.

CAUTION
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.
