A. GENERAL
The following instructions cover 2TTA0030,040,050 & 060AD
Condensing Units.
NOTE:
These outdoor units may be used with indoor units
equipped with Thermostatic Expansion Valve or Accutron™
Flow Control Check Valve (F.C.C.V.) assembly for refrigerant
flow control only.
Check for transportation damage after unit is uncrated.
Report promptly, to the carrier, any damage found to the unit.
To determine the electrical power requirements of the unit,
refer to the nameplate of the unit. The electrical power
available must agree with that listed on the nameplate.
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
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
adequate airflow. Clearance must be provided in front
of control box (access panels) & any other side requir-
ing 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).
4. The top discharge area must be unrestricted for at least
five (5) feet above the unit.

5. When the outdoor unit is mounted on a roof, be sure the
roof will support the unit’s weight. Properly selected
isolation is recommended to prevent sound or vibration
transmission to the building structure.

indoor unit should NOT exceed sixty (60) feet.
7. If outdoor unit is mounted above the air handler,
maximum lift should not exceed sixty (60) feet (suction
line). If air handler is mounted above condensing
unit, maximum lift should not exceed sixty (60) feet
(liquid line).
