Maintenance
When operated properly and with the use of clean and dry gas, RedyCompact devices do not
require any routine maintenance. There are no internal moving parts in the measurement part of
the device. However, we recommend that the calibration is checked after 12 months. If your
RedyCompact is still within tolerance, this time interval can be extended. The timing of the periodic
check is the customer's responsibility.

Cleaning to Remove Contamination
Depending on the type of contamination, on-site cleaning of the measuring or control device may
be possible. As a first step, we recommend flushing with N
2
or dry air. If it is contaminated with
liquids (ex. oil), pure methanol alcohol (100%) can be used. After cleaning, rinse the RedyCompact
with the optional needle valve position fully open with dry air or nitrogen for approximately 15
minutes to dry out all liquids.
Flow Splitter Disassembly
If the basic body has become contaminated, the flow splitter can be removed. The removal should
only be done by trained service personnel. Removal and Assembly can potentially shift the
calibration of a unit. Disassembly is different for the different device types:
Note: The fourth letter of the article code defines the type of the flow splitter. For example:
GCM-B9EA-BB20 contains a flow splitter of the type B.
Type A

turns)

•
Be careful when handling the device and the individual components.
•
Make sure that the disassembly environment is clean.
•
Do not touch the circuit board or electronic components without first
grounding yourself and the surroundings. Electrostatic discharges can
