Reduces cooling load If the air outside is cooler than the air inside the building during the cooling season (such as early morning or at night), “By-pass” ventilation will draw in the cooler outside air and reduce the cooling load on the system. 2. Night purge “By-pass” ventilation can be used to release hot air from inside the building that has accumulated in buildings a business district during the hot summer season. 3. Office equipment room cooling During cold season, fresh air can be drawn in and used as is to cool rooms where the temperature has risen due to the use of office equipment. In the case of “By-pass” ventilation, the supply air temperature slightly rises more than the outside air temperature because of the heat effect around the ducts or the unit motors. Maintenance (or when “FILTER” and “CLEANING” are indicated on the remote controller) English Remove all dust and dirt on air filters and Lossnay cores at regular intervals in order to prevent a deterioration in the Lossnay functions. Guideline: Clean the air filters once a year. Cleaning the parts 1) Air filters Use a vacuum cleaner to remove light dust.
