Filter Extractor Hook
Filter Spacers
The core media is a fibrous material that is subject to damage through careless work habits. Whenever
foreign objects such as tools are taken inside the ERV cabinet, the core media should be protected by
placing stiff cardboard or some other protective material on top. Make certain the protective material
is clean and dust-free before placing it on the media.
RISK OF DAMAGE TO ENTHALPIC CORES
Whenever working within the ERV cabinet, protect the enthalpic cores from accidental damage. The
core media is subject to damage from dropped tools or other foreign objects.
RenewAire has provided a filter replacement tool called a filter extractor hook.
See picture below.
In ad-
dition, the filter spacers have a tab on the ends where a pull cord can be inserted. With a cord installed
in the tab holes, it is possible to simply pull the cords and withdraw six filters at once.
See image below.
When installing the filter spacers, the foam strip is to be placed against the filter.
Note that when new filters are installed, the filter spacers may tend to fall off the end of the filter receiv-
ing channels. If this happens, simply install the spacers between the first two filters in from the door,
instead of locating them against the access doors.

disc that is threaded and will move up or down on the threaded bolt. The up or down movement
determines the upward force on the sled. With age, the supporting springs may require adjustment by
repositioning the support disc.
If filter thickness is ever changed from 2” to 4” or from 4” to 2” thickness, each of 8 filter receivers will
need to be adjusted up or down to accomodate the desired filter thickness. To make this adjustment,
remove the second bolt set in from the door on each filter receiver and slide the moveable filter receiv-
er up or down against the fixed filter receiver bracket, following the “C” channel paths and replace the
positioning bolt set in the proper hole that lines up at the other end of the “C” channel paths. The same
filter spacers are used with either 2” or 4” filters.
