tional and local codes.
1.
Inspect exterior hoods and vents 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).
IMPORTANT
– Blockage of hoods or vents may cause
an airflow imbalance.
2.

Remove filters off the core.
F
Rinse filters with water or a combination of mild
soap and water. Do not clean in the dishwasher.
G
To reassemble, place clean filter(s) – wet or dry –
back into their positions against the core and re-
turn clips to their original position.
H
Slide core back into its original position.
IMPORTANT

With all four corners in place and the core straight
and even, push hard in the center of the core until
the core stops on the back of the cabined.

Core will appear to stick out from cabinet approxi-
mately 1/8" (3mm). This is designed this way so
that the access door will fit tight against the core.

once every year. (A capable HVAC service company
will best perform this procedure.)
8.
Clean the blowers
NOTE − A capable HVAC service
company will best perform this procedure.
blowers
may accumulate dirt causing an imbalance and/or ex-
cessive vibration of the HRV/ERV unit. A reduction in
the airflow may also occur. In new construction, this
may result within the first year due to heavy dust and
may occur periodically thereafter over time depending
on the outdoor conditions.
A
Unplug the HRV/ERV unit; open the service door.
B
Remove the core.
C
Remove ducting (metal and/or flexible insulated
type) from the ports which are connected immedi-
ately inline with the fan assembly.
D
Use a small brush and insert through the large
opening of the fan assembly and then through the
smaller opening in the end of the fan assembly.
E
Scrub individual fan blades until clean. Avoid mov-
ing or damaging balancing flat weight (clip is usu-
ally found on one or more of the fan blades).

Vacuum and wipe out.
G
Reassemble. Be sure ducting is attached firmly.
Seal and tape insulation and moisture barrier.
