Maintenance Routine
1. Inspect Exterior Hoods at Least Once a Month
Make sure exhaust and fresh air supply hoods are not blocked or restricted by leaves, grass,
or snow. In winter, it is especially important to make sure snow is not blocking the hoods or
that frost has not built up on the wire mesh (bird screen).
2. Clean Air Filters (Clean Four times a Year)
The standard filters equipped with your ERV are removable and washable.
a) Open access door and slide core out.
b) Remove filter clips if present.
c) Once clips are removed, filters can be taken off the core to be rinsed with water or a
combination of mild soap and water. Do not clean in the dishwasher.
d) To re-assemble, place clean filter(s) (wet or dry) back into their positions against the core
and return clips to their original positions.
e) Slide core back into its original position.
3. Clean Core Twice a Year
a) Open access door.
b) Carefully grip ends of core and pull evenly outward. Core may be snug, but will slide out
of the cabinet.
c) Once removed from the cabinet remove filters.
d) Clean core gently with vacuum
e) Install the cleaned filters.
f) Install clean core in the cabinet.
Note: Core installation label on the outer end of the core.
To Install the Clean Core:
a) To reinstall the core first position the bottom of the core on the bottom support in the
cabinet.
b) Carefully align the core with the other 3 supports and fully insert the core.
c) Push on sides of core, do not push on the center.
Note: Core may appear to stick out from the cabinet approximately 1/8 in (3 mm). This is
designed this way so that the access door will fit tight against the core.
