Appendix A - Block-Out Construction - Carrier 42S Series Instruction Manual

This section provides rough guidelines for the block-out slot size
for 42S units with risers included. Therefore, the floor block-out
slot dimensions listed in this document should be considered esti-
mates. The engineer for the project is ultimately responsible for
the actual dimensions and meeting local code requirements.
To select using the following Tables A-D, locate the appropriate
unit size in the cabinet charts (dimensions are given in inches).
Then, follow the row across to locate the clear height (If the clear
height exceeds 96 in. use the 96 in. block-out size). Under type of
installation, read the block-out size. If the clear height is lower
than listed or is not recommended (NR) in the standard 88 in. cab-
inet chart, use the short 79 in. cabinet chart. If the clear height is
lower than listed or is not recommended (NR) in the short 79 in.
cabinet chart, please contact the factory.
For examples of clearance height, unit placement, and riser length
see Fig. A. For possible piping arrangements of the 42SJ unit see
Fig. B.

a. CLEAR HEIGHT is the dimension from the floor to ceiling (See Fig. A of this
appendix).
b. The above charts allow 1 in. tolerance in clear height to allow for variance in
floor-to-floor dimensions.
c. Consult factory for applications with 3 in. and 4 in. risers and insulations ex-
ceeding 3/4 in.
d. See Fig. B for 42SJ unit and piping arrangements.
