3.6 Displacing/replacing pump tubings
The pump tubings must be displaced or replaced at regular intervals.
The TresCon has timers for this that indicate the maintenance activities
required when the relevant service intervals expire. This service menu
"guides" you through the necessary steps. The service routine consists
of two parts to enable the work on the instrument to be performed at the
correct time.
Note
The instrument indicates when the pump tubings must be displaced/
replaced by a timely message (service intervals).
