EGM-5 Operation Manual V. 1.04 119 support@ppsystems.com
Maintenance
The EGM-5 requires minimal maintenance. There should be no need to open the enclosure to access
internal components (e.g., battery, pump, IRGA, etc.). The two most common items requiring periodic
inspection and maintenance include:
• External air filter
• Absorber column and desiccant
Both of the above items are external to the EGM-5 and easy to service and maintain.
External Air Filter
An external air filter should be used at all times and fitted in-line with the GAS IN port on the EGM-5 to
protect internal components from dirt and dust (see below). The main assembly (STD558) should not
require replacement unless it is broken or missing. You can purchase replacement filters (STD556) for
use with the main assembly if required.
When changing out filters you should put a slight smear of silicone grease on the “O” ring which provides
a good seal on the filter.
