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.

TABLE 3 — RETROFIT WALL SLEEVES

*FR-SLEEVE-EXT accessory is required for retrofit into Friedrich

(T-Series) wall sleeves.

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.
