B. LOCATION & PREPARATION OF THE UNIT
1. When removing unit from the pallet, notice the tabs on
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 "Trane APB2001-02".
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
adequate airflow. Clearance must be provided in front of
control box (access panels) & any other side requiring
service access to meet National Electrical Code. Also,
the unit location must be far enough away from any
structure to prevent excess roof run-off water from
pouring directly on the unit. Do not locate unit(s) close to
bedroom(s).
