INSTALLATION

Install coil in the horizontal run of a supply air

duct from any furnace. Fig. 2 shows typical

installations. Attach ductwork to encased coil. Use

straps for hanging. Do not drill or screw into coil

condensate pan. Coil must be level for proper

condensate drainage.

If the duct cross-sectional area between coil and

furnace is smaller than entering air opening of

encased coil, a transition must be made in the duct.

The ratio of transition in the duct must not exceed

more than one inch for every seven in both the

horizontal and vertical planes.

Where it is necessary to reduce fan noise or

vibration, install a canvas connection in the duct

work on the entering air side of the coil.

When encased coil is installed in a crawl space,

attic or basement with less than 18 in. service

clearance above the unit, it is not possible to

service unit thru the access panel. In these cases,

part of the ductwork must be cut away or unit

must be removed from duct for servicing.

Fig. I.

COILS 002 THRU 005 use Carrier Compatible

Fittings and accessory tubing package for connec

tions. Detailed instructions are included with the

tubing package. Do not remove rubber plugs from

Carrier Compatible Fittings on the coil until ready

to connect the suction or liquid line into the

fitting. If coil piping is left open, vapor holding

charge will escape and allow moisture to enter.
