Wall Opening Requirements
Before installing the unit, check the wall opening to be sure
the wall sleeve will slide into the opening unobstructed. For
masonry walls, a lintel must be used to provide support over
each opening. The rough opening should measure 16

match the height of the subbase selected. The subbase is
available in either a 3˝ or 4˝ height and is required for 265V but
is optional for 208/230V. Each subbase has leveling legs to
provide up to 1˝ additional height. When no subbase is used,
the opening can start right at the finished floor level (208/230V
only). Leave enough space for carpeting, etc.

Unit Installation – General
Heat pump models will generate condensate during the
heating season. If it is not desirable for this condensate
to exit outdoors from the wall sleeve drain holes, install
indoor or outdoor drain kits, available from your sales
representative (see page 7).
