, the horizontal drip
tray should be removed. See Figures 5, 6 and 7.
Tray removal requires that the coil be removed
by sliding the coil out on the coil channel sup-
ports. There is a coil support tab at the top of the
coil connected to the case must be removed first.
Remove 1 inch insulation strip covering the lip of
the drip tray. The tray is detached by removing
the two screws at the drain pan. Remove the two
screws holding the two brackets at the top of the
coil. Remove drip tray by gently breaking the
seal between the drip tray and drain pan.
b. Remove the factory installed baffle assembly
from the apex of the coil by using a 5/16"
nutdriver to remove the screw. Replace this
baffle with the factory supplied narrow coil baffle
using the screws removed previously. See Figure

CAUTION
!
When installing the narrow coil baffle, make sure to
align the baffle up with the holes so NOT to puncture
the coil tubing.

dation. If Pedestal is not used, a frame strong
enough to support the total weight must be pro-
vided. Provide a minimum height of 14 inches for
proper unrestricted airflow.

dler, it must be the same dimensions as shown in
the outline drawing on page 14.
e. Pedestal and unit should be isolated from the
foundation using a suitable isolating material.

tight and per Local codes.
