Final inspection after installation.
• Check that the circuit voltage is 230V AC 50-60 Hz.
• Monitoring of valve and unit function by starting the test operation.
• The down-time-cleaning procedure is tested by briefly opening and closing the terminals
E1 and E2 (first select DTC mode 1)
• The pressure difference action can be tested or simulated. By squeezing the top hose (in-
side the control box) with the fingers until the text indicates an increasing pressure, its ef-
fect can be simulated. When
When the pressure sinks below
MAX is once again exceeded.
• Check whether the covers on the electrical controllers are properly and tightly mounted.
