Left Bottom right Right Die-cutting Front panel slit Bottom left Changing drain hose Rear left Piping preparation Fig. 8-4-12 2) Firmly insert drains cap. No gap Do not apply lubricating oil (refrigerant machine oil) when inserting the drain cap. Application causes deterioration and drain leakage of the plug. · Since dewing results in a machine trouble, make sure to insulate both the connecting pipes. (Use polyethylene foam as insulating material. ) · When bending a pipe, carefully do it, not to crush it. NOTE · Hole should be made at a slight downward slant on the outdoor side. Do not rise the drain hose. Do not form the drain hose into a wavy shape. 8-5. Installation place · A place which provides the spaces around the outdoor unit as shown in the left diagram. · A place which can bear the weight of the outdoor unit and does not allow an increase in noise level and vibration. · A place where the operation noise and discharged air do not disturb your neighbors. · A place which is not exposed to a strong wind. · A place free of a leakage of combustible gases. · A place which does not block a passage. · When the outdoor unit is to be installed in an elevated position, be sure to secure its feet.
