EGM-5 Operation Manual V. 1.04 25 support@ppsystems.com
Routine System Checks Before Starting
The EGM-5 is designed to operate with minimal maintenance. The basic routine system checks are as
follows:
• Make sure the external air filter (Part No. STD558) is fitted to the GAS IN port. This will ensure
that the sample air is filtered before entering the system.
• Check the absorber column on the back and make sure that it is properly seated in its manifold.
You should periodically lubricate all O-rings associated with the column (black end caps) with
silicone grease to ensure good seal and to avoid problems associated with cracks and leaks. Also
ensure that the gray foam filters are in good shape and replace when worn.
• Check the condition of the CO

scrubber (i.e. soda lime) and make sure it is fresh. If you are
using self-indicating soda lime you can visually make this determination. If you are using non-
indicating soda lime then power up the instrument and check the status (see below). If below 20%
you should change it and reset the absorber column life. See Reset Abs Settings on page 38.
• System Power and Heartbeat - Make sure that the heart symbol is flashing in the upper left
hand corner after the instrument is powered on. Also check the battery capacity next to the heart
to ensure that you have plenty of power to get you through your measurements.
