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).
WARNING: Blockage of hoods may cause an imbalance.
2. Clean Air Filters (clean twice a year)
The standard filters equipped with your HRV are removable and
washable.
a) simply 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
position
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 channel
c) once removed from the cabinet remove filters
d)
ERV core
- Vacuum the core or rinse with cold water (DO
NOT USE SOAP, DISHWASHER OR A PRESSURE
WASHER.)
HRV core
- Soak in warm soapy water and rinse
e) install the clean filters
f) install clean core
Note: Core installation label on the outer end of the core.
To install the clean core:
a) first mount the bottom flange of the core guide into the bottom
H channel approximately 1/4” (6mm)
b) mount the left or right side flange of the core guide
approximately 1/4” (6mm) followed by the other side
c) mount the top flange of the core guide into the top H channel
approximately 1/4” (6mm).
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 cabinet.
NOTE: Core will appear to stick out from cabinet approximately 1/8”
(3mm). This is designed this way so that the access door will fit tight
against the core.
4. Motors - Maintenance Free
5. Drain (condensate) Line - Clean once a year
Inspect drain line, drain spout and “P” trap for blockage, mold or
kinks. Flush with warm soapy water and replace if worn, bent or
unable to clean.
6. Clean Duct Work if Required
The duct work running to and from the HRV may accumulate dirt.
Wipe and vacuum the duct once every year. You may wish to
contact a Heating/Ventilation company to do this.
7. General Maintenance - Twice a Year
Wipe down the inside of the cabinet with a damp cloth to remove
dirt, bugs and debris that may be present.
8. Cleaning the Fans
Fans may accumulate dirt causing an imbalance and/or excessive
vibration of the HRV. A reduction in the air flow may also occur.
In new construction this may result within the first year due to
heavy dust and may occur periodically after that over time
depending on the outdoor conditions.
• unplug the HRV and open the service door
• remove the core
• remove ducting (metal and/or flexible insulated type) from
the red and/or blue ports which are connected immediately
in-line with the fan assembly
• use a small brush, such as an old toothbrush or pipe cleaner,
and insert first
(a)
through the large opening of the fan
assembly and then
(b)
through the smaller opening in the end
of the fan assembly.
• 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
• vacuum and wipe
• reassemble making sure ducting is reattached firmly and
insulation and moisture barrier are sealed and taped
Before attempting this task, thought should be given to having a
qualified service technician complete the service work.
