the basepan. Remove tabs by cutting with a sharp tool as
shown in Figure 2 (see page 2).
2. The unit should be set on a level support pad at least as
large as the unit base pan, such as a concrete slab. If this
is not the application used please refer to application
bulletin SSC-APG002-EN.
3. The support pad must NOT be in direct contact with
any structure. Unit must be positioned a minimum of
12" from any wall or surrounding shrubbery to insure

of control box (access panels) & any other side requir-
ing service access to meet National Electrical Code.

pouring directly on the unit. Do not locate unit(s) close
to bedroom(s).

five (5) feet above the unit.
