Product Description
The product is a portable heat recovery ventilator which is housed in a compact and
attractive cabinet enclosure. The heat recovery ventilator is designed to supply filtered,
fresh air into a building space, passively regulate the temperature and humidity of air,
and simultaneously expel stale air and contaminants from the same space.
The external and internal parts of the product are visually depicted in Figures 1 and 2,
respectively.

22ºC – 24ºC and 35% – 50%, respectively.

The product shall not be powered until the ducts (B and D) are installed.

A ventilation kit (not bundled with the product) is needed to install the two
ducts (B and D) such that air can securely and simultaneously be supplied
to and expelled from the building space.

The ventilation kit can interface with the outdoors though a window, door
or wall as illustrated in Figure 3. The customer is responsible for
complying with all applicable codes and regulations.

To power the product, connect the plug of the power supply cord (E) to
the wall power (~120V AC, ~60Hz). To shut down the product,
disconnect the power supply cord (E) from the wall power.

installed at a location
where there is probable
contact with liquids.
NOTE 

RECOMMENDATIONS

Screens (not bundled with the product) shall be attached to the ports of the ventilation kit
to prevent the encroachment of animals that can damage the product or constitute hazard
to the building occupants.

A minimum separation distance of 1 ft is recommended between the supply and exhaust
ducts.

The ducts (B and D) shall be installed without any bends that may impede the flow of air.

The ducts (B and D) shall be insulated to minimize energy losses.
Maintenance
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 filter in the supply vent (A) at least once in three
months depending on the outdoor air quality. The procedure for changing the filter is
presented as follows.

To remove the old filter in the supply vent (A):
o Shut down the product;
o Open the door of the enclosure;
o Locate and hold the heat exchanger (H) firmly with one hand;
o Carefully twist and pull out the supply vent (A) with the other
hand.
NOTE 
The heat exchanger (H)
shall not be washed.
NOTE 
A filter shall not be
installed in the exhaust
vent (C).
6

Remove the filter in the supply-vent (A) port and replace it with a new
filter.

To reinsert the supply vent (A):
o Clean the vent (A) with a paper towel that is moistened with
isopropyl alcohol;
o Use one hand to hold the heat exchanger (H) and ensure that it
lines up with the port of the supply vent (A) at the top of the
enclosure;
o Use the other hand to insert the supply vent (A) into the port until
it is flush with the top surface of the enclosure.
Duct
A damaged duct can be replaced by using a similar duct with a diameter of 4 in
(~10.2 cm).
The following steps can be followed when changing a duct:
o Shut down the product;
o Loosen the nuts of the clamp of the damaged duct;
o Remove the damaged duct from the port of the appropriate fan;
o Attach a new duct to the port of the appropriate fan;
