Pump head maintenance message
The effective runtime of the pump head is counted during operation.
After 150 hours of operation, the LED E4 flashes with the mainte-
nance message for the pump head. This runtime for the pump will be
reached during normal operation (analysis interval every 10 minutes)
after approx. 2 years or 54000 analyses.
Switch off the instrument to acknowledge the message.
Press and hold key 4 (horn) when switching on the instrument.
The operating time of the pump head is then reset to 0.
Replacing the pump head
We recommend you to replace the pump head when the mainte-
nance message for the pump head is displayed.
