INSTALLATION
Proper installation is the responsibility of the
installer.
Product failure due to improper installation is not
covered under the Warranty.
CHASSIS INSTALLATION
Units are shipped without a sleeve. In applications
where unit is a replacement, it is recommended that a
Gree sleeve be used.
UNIT DAMAGE AND/OR OPERATION HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
For retrofit applications, foam seals on outdoor coil tube
sheets must make a seal between the coil and the grille or
loss of performance and premature damage to the major
components can result.

(T---Series) wall sleeves.
Minimum wall sleeve opening must be greater than
14.75 X 40.00 in. (374.7 x 1016 mm)
These units can retrofit Carrier, General Electric,
Amana, Trane, and Friedrich sleeves/grilles (be sure
outdoor grille is installed on the sleeve). See Table 3
for details. Gree engineering must approve any other
retrofit application.
For competitive retrofit applications, be sure that the
foam seals (factory-installed on the tube sheets)
provide a good seal between the grille and outdoor coil
tube sheets. These foam seals provide a barrier to
separate outdoor coil leaving air from mixing with
the outdoor incoming air (known as air recircula-
tion).
