INSTALLATION

CHASSIS INSTALLATION

Units are shipped without a sleeve. In applications where unit is a replacement, it is recommended that a Carrier sleeve and grille be used.

The 52C and 52P 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. Carrier Corporation must approve any other retrofit application.

For competitive retrofit applications, be sure that the foam seals (factory-installed on the tube sheets) pro- vide a good seal between the outdoor grille and out- door coil tube sheets. These foam seals provide a barrier to separate outdoor coil leaving air from mix- ing with the outdoor incoming air (known as air recir- culation).

See Figure 5.

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.
