It is necessary to make space for the cleaning and
maintenance of the drain pan, the heat exchanger and filter
fixed inlet.
Do not put any obstacle not to cause obstructing
maintenance or cleaning works.
If the place where the ceiling material cannot be removed,
make an
inspection access (800 × B) below the bottom
surface of the indoor unit in order to take it out.
If no space to provide inspection access (800 × B), there are two alternative cases (1 or 2 as below). However, when choosing
those cases, there is not enough space available to offer heat exchanger maintenance service.
1
Make space more than 300 mm between the indoor unit’s
bottom surface and the ceiling material.
2 Install inspection access (450 × 450) both edge of indoor
unit and make space more than 100 mm between the indoor
unit’s bottom surface and the ceiling material.
