Activated Carbon Filter Replacement Procedure
The filter without condensate drain tube extending from the bottom of the filter housing is an activated carbon
filter. To replace the filter cartridge follow the steps below:
Step 7:
Remove the filter housing bowl by unscrewing it from the top portion of the filter housing which is
connected to the internal system piping.
Step 8:
Once the filter housing bowl has been removed, the filter cartridge inside is removed by first unscrewing
the black retaining disc at the base of the cartridge and then pulling down on the cartridge. Discard the
old filter cartridge and replace it with the appropriately marked filter cartridge from the maintenance kit
by pushing up so that it fits snugly onto the receiving stepped cylinder in the upper part of the filter
housing. Screw the black retaining disc back onto the central metal threaded rod.
Important: HAND TIGHTEN ONLY!
Step 9:
Replace the filter housing bowl by screwing it onto the filter housing top.

The ECS Protector Nitrogen Generator can now be placed back into service.
