Notes:
1. Please use after confirming the "operating ambient temperature" described in the "specification list".
2. It is for general living rooms and cannot be used even within the above conditions under extreme cooling conditions such as a
refrigerator with a large temperature difference.
3. In addition, even if it is within the usage conditions, it may be necessary to take measures against dew condensation depending
on the air conditions, so please refer to the precautions described in the technical section at the end of the catalog and use it in
an environment that satisfies the conditions.
4. Condensation may form on the main body and duct depending on the temperature and humidity conditions around the main
body.
Water may leak out of the machine.
5. Cannot be used in high humidity conditions such as heated pools, bathrooms, and mushroom cultivation rooms.
6. If the indoor air or outdoor air exceeds 50°C, the life of resin parts such as air filters may be shortened or the life of electric parts
such as motors may be shortened due to insulation deterioration.
7. Cannot be used in places where indoor air, outdoor air, and air at the product installation location generate harmful gases such
as acids, alkalis, organic solvents, oil mists, paints, and pesticides, and gases containing corrosive components.
8. If it is installed in a building near the coast and it is considered necessary to take measures against salt damage, connect a filter
for repairing sea salt particles (filter for preventing salt damage) to the outside air suction port (OA) side by duct.
9. In cold regions or places with strong outside wind, cold air may enter through the duct when the operation is stopped. As an
intrusion prevention measure, install electric shutters (locally arranged) for each of the outside air suction (OA) and exhaust
blowout (EA).
10. Inhaling fog, haze, or high-humidity air may cause water droplets to drip from the air filter and heat exchange elements, leading
to water leakage to the outside of the machine or failure of electrical parts such as damper motors. In such a case, stop the
operation. In cold regions, indoor negative pressure, and places with strong outside wind, outside air may be sucked in even if
the operation is stopped.
In such cases, outside air suction (OA) and exhaust blowout (EA) are taken as measures to prevent intrusion. Install electric
shutters (locally arranged) for each.
11. In suburban buildings, there are windows and outdoor lights near the outside air suction port (OA), and in an environment where
insects tend to collect in the illumination light, minute insects that have invaded from the outside air suction port (OA) pass
through the air filter.
It may invade the room. At the design stage, we ask you to consider measures against insect invasion such as filter boxes
(locally arranged).
12. Install the exhaust suction port (RA) at a position where the air blown from the air conditioner, etc. is not directly sucked.
13. Be sure to provide an inspection port for maintenance on the outlet side of the air filter and total heat exchange element.
14. Be sure to insulate the two outdoor ducts (outside air suction (OA) and exhaust outlet (EA) ducts) to prevent dew condensation.
In cold regions where the outside air temperature is 10°C or less, dew condensation may also form on the indoor (SA) duct, so
perform heat insulation treatment.
15. Do not use the vent cap or round hood in a place exposed to direct rainwater.
16. Ensure that the pitch between the exhaust outlet (EA) and the outside air inlet (OA) on the outdoor outer wall is at least 3 times
the duct diameter.
