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 win-
ter, 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
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 dishwash-
er
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) wash core in warm soapy water (do not use dish-
washer)
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 centre of the core until
the core stops on the back of the cabinet.
NOTE: 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.
4. Motors - Maintenance Free
5. Drain (condensate) Line - Clean once a year
Inspect drain line, drain spout and “P” trap for block-
age, mould 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 accu-
mulate 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 inline with the fan assem-
bly
• 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 ser-
vice work.
