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 or
Carrier sleeve be used.
These units can retrofit General Electric, Amana, Trane, and Friedrich sleeves/grilles (be sure outdoor
grille is installed on the sleeve). See Table 3 for details.
For
any sleeve
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 recirculation).
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.
