Drum HYDRAPAK - Changing The Filter Element

4.3 Changing The Filter Element
The life expectancy of the lter element is approximately 9 months. Gardner
Denver Drum recommends that the lter condition is checked on a regular
basis.
The cooler is tted with a lter condition gauge (6) which is located at the
front of the outer cover of the Hydrapak. When the needle of the gauge has
reached the ‘Red’ section of the gauge the lter element will need changing.
1. Unscrew Filler Cap (1) and remove, then unscrew and remove lter
retaining nut (2).
2. Remove Strainer Disc (3) from the sealing ring and remove the
spring (4) located on top of the lter element .
3. Withdraw the lter element (5) from the Hydrapak reservoir. The
lter is a non-serviceable item and must be replaced at the end of its
service life.
Re-tting a new Filter Element is a reversal of the above.
Maintenance
Spring tension is released
during this operation.
