INSTALLATION SITE PREPARATION - Continued

Inside installation. Manufacture an arrangement of ducts for the condenser intake and discharge air openings,

and the fresh air damper intake and/or CBR filter intake, if installed. Ducts may be made for attachment to the

air conditioner cabinet using the mounting holes for the condenser inlet and outlet guards and grilles, and the

fresh air filter frame and/or the air intake on the CBR filter or some other arrangement may be made. Prepare

appropriate openings in an exterior wall for the ducts. Ducts may be designed to use the condenser inlet and

outlet guards and grilles and the fresh air filter and frame supplied with the air conditioner and relocated and

installed on the new duct work. Adequate replacements or some other arrangement of these items may be

provided.

CAUTION

Easy access to air filters must be provided. Filters maybe left in unit or relocated

in duct work. Some installations (filters relocated in duct work) may require differ-

ent size filters.

d. Outside installation. Manufacture an arrangement of ducts for the conditioned air intake and discharge air.

Ducts may be made for attachment to the air conditioner cabinet using the mounting holes for the conditioned

air intake and discharge grilles or some other arrangement may be made. Ducts may also be made for installa-

tion of the conditioned air intake and discharge grilles on the inside ends or replacements for these items may

be used. Prepare appropriate openings in the appropriate wall for the ducts.

NOTE

Retain all items removed from air conditioner. Store them in a safe place. These parts
