1.7 INPUT AND OUTPUT SERVICES
1. Water pressure
Best performance will be realized if water or provided at a pressure of 30 – 8
7
psi (2 –
6
bar). Although the machine will function properly at lower pressure, increased fill time will occur.
Water pressure higher than 120 psi (8 bar) may result in damage to machine plumbing components
failure (s) and personal injuries.
2. Optional Steam heating pressure
Best performance will be realized if steam pressure is provided at a pressure of 30 – 80 psi
(2 – 5.5 Bar). Steam pressure higher than 125 psi (8.6 Bar) may result in steam components and
may cause personal injuries. 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.
3. Compressed Air
For machines requiring compressed air service, best performance will be realized if air is
provided at a pressure of
58
–
87
psi (
4
– 6 Bar). Large capacity machines could experience door
seal failures if compressed air service is interrupted.
4. Drainage System
Provide drain lines or trough large enough to accommodate the total quantity of water that
could be dumped if all machines on the site drained at the same time from the highest attainable
level. If drain troughs are used, they
should be covered to support light foot traffic.
5. 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
conduits or water popes. An easy – access disconnect switch should be provided.
Ensure that a ground wire from a proven earth ground is connected to the ground lug in the
electrical junction box on this machine. Without proper grounding personal injury form electrical
shock could occur and machine malfunctions may be evident. Computer – controlled machines
must have a proper ground to prevent computer malfunctions.
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.
1.8 AC INVERTER DRIVE
Machines equipped with AC drives require special attention with regard to the operating
environment.
1. An especially dusty or linty environment will require more frequent cleaning of the AC drive
cooling fan filter and of the AC drive itself.
2. Power line fluctuations from sources such as an interruptible power supplies (UPS) can
adversely affect machines equipped with the AC drive. Proper suppression devices
should be
utilized on the incoming power to the machine to avoid problems.
