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 released 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. 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.
AC Inverter Drive
Machines equipped with the AC inverter drive require
special attention with regard to the operating
environment.
An especially dusty or linty environment will
require more frequent cleaning of the AC inverter
drive cooling fan filter and of the AC inverter
drive itself.
Power line fluctuations from sources such as
uninterruptible power supplies (UPS) can
adversely affect machines equipped with the AC
inverter drive. Proper suppression devices should
be utilized on the incoming power to the machine
to avoid problems.
A clean power supply free from voltage spikes
and surges is absolutely essential for machines
equipped with the AC inverter drive. Nonlinear
inconsistencies (peaks and valleys) in the power
supply can cause the AC inverter drive to
generate nuisance errors.
The following conditions must be corrected:
input voltage above 240V or 480V, phase to
ground voltage exceeds 125% of normal line to
line voltage, or 240V open delta configuration
(stinger leg). Contact the distributor or the
manufacturer for assistance.
Sufficient space to perform service procedures
and routine preventive maintenance is especially
important for machines equipped with the AC
inverter drive.
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.
