Homeowner Maintenance Information
WARNING
Electric Shock Hazard.
Can cause injury or death.
Disconnect all remote electrical
power supplies before servicing.
Unit may have multiple power
supplies. Unit must be connected
to a grounded power supply in
accordance with national and local
codes.
1.
Inspect exterior hoods and vents at least once a month
and 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.
Clean air filters three times a year. If your unit is
equipped with MERV13 filters, replace every 3 months.
Do not wash MERV13 filters but wash the polyester
filter. The standard filters equipped with the ERV/HRV
are removable and washable:
a. Remove power to the unit.
b. Open access door.
c. Slide the core out.
d.
Remove filter clips if present.
e.
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 return
clips to their original position.
h. Slide core back into its original position.
IMPORTANT
Vacuum ONLY to clean ERV core.
Soak and rinse the HRV core in warm soapy water.
DO NOT use bleach or chlorine.
DO NOT use pressure washer to clean the ERV or HRV
core.
DO NOT use dishwasher to clean the ERV or HRV core.
3.
Clean core and inside of cabinet three times a year
a. Remove power to the unit.
b. Open access door.
c. Carefully grip ends of core and pull evenly outward.
Core may be snug, but will slide out of the channel.
d.
Remove filters as above.
e.
HRV Core
- wash core in warm soapy water (do not
use dishwasher).
f.
ERV Core
- vacuum
ONLY
to clean core, do not get
wet.
g.
Install clean filters.
h. Wipe down the inside of the cabinet with a damp
cloth to remove dirt, bugs, and any debris.
4.
Install clean core as follows:
a.
A Install the bottom flange of the core guide into the
bottom
H
channel approximately 1/4” (6 mm).
b.
Install the left or right side flange of the core guide
approximately 1/4” (6 mm) followed by the other
side flange.
c.
Install the top flange of the core guide into the top
H
channel approximately 1/4” (6 mm).
d. 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.
NOTE: Core will appear to stick out from cabinet
approximately 1/8” (3 mm). This is designed this
way so that the access door will fit tight against the
core.
5.
Motors are maintenance free.
6. Clean Drain
(condensate) line at least once a year
inspect drain line, drain spout, and P-trap for blockage,
mold, or kinks in the line. Flush with warm soapy water
and replace line if worn, bent, or cannot be cleaned.
7. Clean Duct System
if required the duct system from
outside to and from the ERV/HRV unit may accumulate
dirt. Wipe and vacuum the inside of the duct 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 excessive vibration of
the ERV/HRV 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
ERV/HRV unit; open the service door.
b. Remove the core.
c.
Remove ducting (metal and/or flexible insulated type)
from the ports which are connected immediately in-
line 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 moving
or damaging balancing flat weight (clip is usually
found on one or more of the fan blades).
f. Vacuum and wipe out.
g.
Reassemble. Be sure ducting is attached firmly.
Seal and tape insulation and moisture barrier
