Introduction
he User Manual concisely presents the information that is needed to correctly
install and operate the product. Failure to strictly follow the instructions in the
User Manual nullifies the Terms and Agreements of the manufacturer.
Product Description
The product is a portable heat recovery ventilator which is housed in an attractive
polymer enclosure. The heat recovery ventilator performs three functions. First, it
supplies fresh air to a space (ventilation). Secondly, the fresh air that is supplied to the
space is purified with filters while pollutants such as germs, molds, excess moisture,
CO
2
, radon, odors, and particulates are expelled from the space (purification). Thirdly,
the supplied fresh air is passively heated or cooled depending on the outdoor
conditions (comfort). The product is visually depicted in Figure 1.

Maintenance
The product is designed to operate with minimal maintenance. However, a few
activities may be performed during the course of using the product.
The product shall be shut down before ANY maintenance activity is performed.
Filter
It is recommended to change the filters in the supply and exhaust vents at least once in
three months depending on the outdoor air quality. The procedure for changing the
filters is presented accordingly:

Gently unlock the latches of the enclosure of the product and open its lid.

To remove the supply vent, hold the enclosure of the product firmly with
one hand and carefully pull out the supply vent with the other hand.

The filter(s) are accessible in the exhaust vent and the vent itself does not
need to be removed. If applicable, a filter guard (not shown in Figure 1)
may first need to be removed from the exhaust vent before accessing the
filter(s).

MERV4:
o Supply vent: Replace the old filter in the port of the vent with one
sheet of a new MERV4 filter that is cut to a circular shape with a
diameter of 3 in (~7.6 cm).
o Exhaust vent: Repeat the above-mentioned procedure but replace
the old filter(s) using three new MERV4 filter pads.

PM2.5: Remove the old filter in the supply vent and replace it with a new
piece of folded PM2.5 filter.

Carefully re-attach the supply vent to the product.

Carefully close the lid of the enclosure and lock the latches.
Duct
A damaged duct can be replaced by using a similar duct with a diameter of 3 in
(~7.6 cm). The following steps can be followed when changing a duct:

Loosen the nuts of the clamp of the damaged duct.

Remove the damaged duct and attach a new duct.

Tighten the nuts of the clamp.
NOTE 
The length of a newly
installed duct shall not
exceed 5 ft (~12.7 cm).
NOTE 
Do not apply excessive
force when tightening
the clamp.

Heat Exchanger
The heat exchanger may be cleaned annually by implementing these steps:

Detach the supply and exhaust ducts from the board(s) or wall.

Remove the supply vent as explained in an aforementioned step.

Insert the hose of a powered vacuum cleaner into the port of the supply
vent to extract particles from the heat exchanger tubings.

Remove the hose of the vacuum cleaner from the port of the supply vent.

Re-attach the supply vent to the product.

Carefully insert the vacuum cleaner hose by up to 2 ft (~60.9 cm) into the
exhaust duct to extract particles from the shell side of the heat exchanger.
Ensure that the exhaust duct is not damaged while inserting the hose.

Remove the hose of the vacuum cleaner from the exhaust duct.

Re-attach the supply and exhaust ducts to the board(s) or wall.
Electrical Parts
An electrical part shall only be replaced if it is faulty. In this situation, the product shall
be shut down and a qualified service technician may be consulted.
Caveat
The electrical parts of the product are deemed to be certified to ensure customer safety.
Notably, the product operates on the load side of a Class 2 power source in accordance
with Canada Electric Code Rule 16–222 and US National Electric Code Class 2
Article 725–41. The product is also subject to the exemption(s) outlined in Federal
Communications Commission Section 15.103(d). Consequently, the manufacturer is
