Select a position for introducing the outside air where no exhaust or
−
combustion gases will be sucked into the product and where it will
not be covered by snow.
Do not use this product at the cold are during winter time, with the
−
environmental condition that dewing may occur in the heat exchange
element (the case that the line connecting the protted points of the
outdoor/indoor temperature and humidity conditions crosses the
saturation curve on the psychometric diagram).
In such a case, heat the A (Outdoor Air) up to the A' point and make

the condition that the line connecting the protted points of the
outdoor/indoor temperature and humidity conditions does not cross
the saturation curve, and the total heat exchanger can be used.
−
The limit of the environmental conditions for using the total heat
exchanger are shown in the table below as an example, at the outdoor
air temperature 0 °C, -5 °C and -10 °C with the indoor air temperature

In case that the indoor air humidity is higher than this condition or the
outdoor air humidity is extremely high, dewing may occur.
