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
maintenance 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
maintenance message for the pump head is displayed.
The maintenance manual Testomat
®
808 contains a detailed
description of maintenance work.
Motor block maintenance
We recommend that you also replace the motor block each time the
pump head is replaced in order to prevent a failure.
Contact your service partner, who can carry out the replacement, or
send in the device for maintenance.
