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
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) wash core in warm soapy water (do not use dishwasher)
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

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,
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
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 inline 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.
