4 Maintenance
The MSI-3 was designed to be used without virtually any need for intensive maintenance. The
pressurized parts are manufactured from corrosion-resistant material and require no further care.
When using the MSI-3, take care that no particles of soot enter the instrument. After every period
of use, the tapered connection on the bottom part should be cleaned.
If the upper part is disconnected from the bottom part, the copper seals need to be replaced. The
same applies if the pressure gauge has been disconnected.
It must be ensured that even after prolonged periods of use correct measurement data can be
obtained. The instrument should therefore be returned to the LEUTERT factory or authorized
service center for testing and re-calibration every two years.
Please note, that the instrument itself must not get hotter than 60 °C.
WARNING
Do not exceed the maximum working temperature of 60°C. Detach the indicator
immediately from the indicator valve to prevent any unnecessary buildup of heat in the
instrument. After approximately 20 measurements allow the indicator to cool down for 10
to 15 minutes.
Close the indicator valve.
Note the readings.
Open the venting screw to reset the device to zero.
Now the next cylinder may be measured.
NOTICE
Store the indicator when not in use with the venting screw open in order to allow
condensation to escape, which may take a couple of hours.
