INSTALLATION
CHASSIS INSTALLATION
Units are shipped without a sleeve. In applications
where unit is a replacement, it is recommended that a
Carrier sleeve be used. The 52C and 52P units can
retrofit General Electric, Amana and Trane sleeves/
grilles (be sure outdoor grille is installed on the
sleeve). A retrofit kit with instructions is included
with every unit. See Table 3 for details. Carrier Corpo-
ration must approve any other retrofit application. In
deep-wall applications, if an existing grille is used on
an outdoor wall opening, do not install an additional
outdoor grille on unit sleeve.
Be sure that the foam strips and/or baffles provide a
good seal between the grille and condenser coil tube
sheets. These foam strips or baffles provide a barrier
to separate condenser air from the major components
(compressor and fan motor). See Figures 5 to 8.
NOTE: Inspect wall sleeve for any damage or deterio-
ration before installing chassis.
TABLE 3 — RETROFIT WALL SLEEVES
*Retrofit kit is not needed for Carrier or Bryant applications.
If baffles are not installed properly, loss of perfor-
mance and premature damage to the major compo-
nents can result.
