GENERAL

This instruction covers the installation of the following Stellar
ULTRA 

 high efficiency condensing units.

NOMENCLATURE

The outdoor condensing units are designed to be installed with
corresponding variable speed air handlers and a correspond-
ing coil with sweat connect lines. Each unit is factory charged
with refrigerant sufficient for the smallest indoor evaporator coil
plus 15 feet of field supplied vapor and liquid lines.  A balanced
port hard shut-off TXV kit must be used for optimum system
performance.

SAFETY

Use this instruction in conjunction with the instruction for the
appropriate indoor evaporator coil, variable speed air handler  and
other accessories. Read all instructions before installing the unit.

Installer should pay particular attention to the words:NOTE,
CAUTION and WARNING.

NOTES are intended to clarify or make the installation easier.

CAUTIONS are given to prevent equipment damage.

WARNINGS are given to alert the installer that personal injury
and/or equipment damage may result if installation procedures
are not handled properly.

INSPECTION

As soon as a unit is received, it should be inspected for possible
damage during transit. If damage is evident, the extent of the
damage should be noted on the carrier’s freight bill. A separate
request for inspection by the carrier’s agent should be made in
writing. See Form 50.15-NM for more information.

LIMITATIONS

The unit should be installed in accordance with all national and
local safety codes and the limitations listed below:

1. Limitations for the indoor unit, coil and appropriate acces-

sories must also be observed.

2. This unit 

should not be installed with a single speed air

handler or furnace system.

3. The outdoor unit must not be installed with any ductwork in

the air stream. The outdoor fan is the propeller type and is
not designed to operate against any additional external
static pressure.

4. The unit should not be operated at outdoor temperatures

below 60 

°

F. 

The unit is not designed to operate with a

low ambient kit. Do not modify the control system to
operate with any type of low ambient kit.

5. Indoor evaporator coil orifice 

must be removed prior to

the installation of a factory supplied balanced port TXV kit.
