IMPORTANT -- This Document is customer property and is to remain with this unit. Please return to service information pack
upon completion of work.
These instructions do not cover all variations in systems
nor provide for every possible contingency to be met in
connection with installation. All phases of this installa-

the purchaser's purposes, the matter should be referred to your
installing deal or local distributor.
GENERAL
The following instructions cover TTP018-024C, TTP030-048D &
TTP060E Condensing Units.
NOTICE: These outdoor units may be used with indoor
units equipped with Capillary Tube, Thermostatic Ex-
pansion Valve or the Accutron TM Flow Control Check
Valve (F.C.C.V.) assembly for refrigerant flow control.
Check fbr 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 nmst
agree with that listed on the nameplate.
B. LOCATION & PREPARATION OF THE UNIT
1. The unit should be set on alevel support pad at least as large
as the unit base pan.
2. The support pad must NOT be in direct contact with any
structure. Unit nmst be positioned a minimmn of 12" from any
wall or su rrou nding shrubbery to insure adequ ate airflow. Clear-
ance must be provided in f_ont of control box (access panels) &
any other side requiring service access to meet National Electri-
cal Code. Also, the unit location must be far enough away fi'om
any structure to prevent excess roofrun-offwater from pouring
directly on the unit.
3. The top discharge area must be unrestricted fbr at least five
(5) feet above the unit.
4. 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 transmission to the building structure.
(_ TOP DISCHARGE--- UNRESTRICTED
5 FT. ABOVE UNIT
5. The maximum length of refrigerant lines fi'om outdoor to
indoor unit should NOT exceed sixty (60) feet.
6. If outdoor unit is mounted above the air handler, maximum
lift should not exceed sixty (60) fbet (suction line). If air handler
is mounted above condensing unit, maximum lift should not
exceed sixty (60) feet (liquid line).
NOTE: Refer to R@'igerant Piping Software, Pub. No. 22-3312-01.
7. Locate and install indoor coil or air handler in accordance
with instruction included with that unit.
