5.2. Replacing and Cleaning the Air Filter
The primary air filter is crucial to keep debris and particulate matter from getting into the
system. This filter should be regularly swapped with a clean air filter. For a typical GreenFeed
setup, the filter should be swapped once per week. But several factors can contribute to the
duration between changing air filters. Every GreenFeed comes with two (2) air filters. So one
can be in use while the other one is being cleaned and dried.
When the time comes to swap the air filter, please perform the following steps:
1) Turn the fan off. You can do this by either putting the GreenFeed to sleep, or by
issuing the “Fan Off” command (Section 3.2). Wait for the fan to fully stop.
2) Undo the top two latches on both sides of the back of GreenFeed. These latches hold
the back top cover in place.
3) Once both top latches are loose, lift up the door to expose the air filter box.
4) Unlatch the air filter door and open it.
5) Unlatch the clamp on the old air filter and remove it from the filter box.
6) Remove the clamp from the old air filter and place it on the new air filter.
7) Put the new air filter over the pipe in the same manner the old air filter was placed.
8) Tighten the clamp to secure the air filter in place.
9) Close the door and latch it shut.
10) Shut the top door to cover the air filter box and tighten the top two latches to hold it
in place.
11) Turn the fan back on. See Section 3.2 for instructions.
Dirty air filters can be cleaned using one of the following methods:
1) Running hot water into the inside of the air filter, then letting it drain out. Do this
several times, and ensure water is thoroughly rinsing all areas inside the air filter.
When finished rinsing, set in a dry location overnight to allow for drying.
2) Pressurized air (~50psi or 3500 mbar) can be used to clean out dirty filters.

Over time, the reusable filters will require cleaning much more often. This usually occurs
after 1 year of full use. It is recommended to dispose of the air filters at this time and
purchase replacements. Contact sales@c-lockinc.com for replacement air filters.
