1. Installation
1.1 System Components
1.1.1 Wash System
Dynamic Washing Method
On startup, the control system admits only as much water as is needed for proper operation
of the circulation pump. Depending on application rack or machine loading, an adequate
additional quantity of water is introduced. This method assures optimal cleaning perform-
ance while conserving the use of water and chemicals.
Wide Range of Machine Application
The machine is equipped with a powerful circulation pump of 750 liters / minute at 7.5 psig
pumping capacity. The extremely flat characteristic line of this device ensures maximum
quantity of water on wash goods, thus assuring best possible cleaning results.
Docking
A cylindrical bushing on the machine rack docking point is being pressed against the wash
rack by water pressure. This bushing is designed to make for a perfect connection, insuring
best possible water flow to the rack. By means of a retaining spring, the bushing will reset to
standby position upon pressure loss (e.g. end of program or malfunction).
1.1.2 Control System
The machine is equipped with a programmable logic controller (PLC). By keyboard entry,
selection of six pre-defined programs are available.
Another fine feature is the self-diagnostic test routines. Automatic tests are performed
regularly. This is an early warning system for potential machine problems. Respective input
signals are permanently monitored, deviations beyond preset tolerances cause acoustic
alerts and are indicated on display.
External Printer (optional)
Following information may be recorded by an external printer:
1 Test report
2 Error codes with indication of machine status
3 Program printout of actual readings
