cover at the point of installation.
If components are to be added to a unit to meet local codes,
they are to be installed at the dealer’s and/or customer’s
expense.
The size of unit for the proposed installation should be based
on heat loss/heat gain calculation made according to the
methods of Air Conditioning Contractors of America (ACCA).
See Table 1 for fi lter information and application limitations.
These installation instructions are intended as a general
guide only, for use by an experienced, qualified
contractor.
