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

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.
If baffles are not installed properly, loss of perfor- mance and premature damage to the major compo- nents can result.
