If condensation is expected to form, heat up the fresh outside air using a duct heater, etc. 2. An inspection port (4 4 6 6 mm) must be installed on the filters and Lossnay cores removing side. 3. The two outdoor ducts must be covered with heat-insulating material in order to prevent condensation from forming. The two indoor ducts may be covered with heat-insulating if Lossnay is to be installed in the circumstance of higher temperature in summer. 4. Installing the duct damper is preferred also to prevent the outdoor air introduced to room if there has strongthern wind, when the unit operates or stops.. The outside ducts must be tilted at a gradient (/3 or more) down toward the outdoor area from Lossnay unit. DRAWINGS AND DIMENSIONS 7-Jun.- LGH-RX3 NUMBER No. ND6 2/4
