IX. CONVERSION PROCEDURE
1. HORIZONTAL TO DOWNFLOW
a. Remove screws and covers from the downflow supply and return sections. Both
covers are accessible from the inside of the unit.
b. Install gasket (supplied with parts bag) around perimeter of cover on the insulat-
ed side. In other words, the gasket is applied to the
opposite
side of flange than
shown in Figure 10.
c. Install covers on the outside of the unit over the horizontal supply and return
opening using existing screws.
2. DOWNFLOW TO HORIZONTAL
a. Remove screws and covers from outside of supply and return sections.
b.
Install gasket (supplied with parts bag) around perimeter of covers as illustrated in
“Cover Gasket Detail.”
c. Install covers in bottom of unit with insulated side up. NOTE: Slip back flange of
cover under tab on bottom supply duct opening.
d. Secure covers to base of unit with screw engaging prepunched holes in unit base.
X. CONDENSATE DRAIN
The evaorator coil condensate drain ends with a threaded 3/4” nominal PVC stub. A trap
is built in for proper condensate drainage and to prevent debris from being drawn into
the unit. Do not connect drain to closed sewer line. Connection to a vented sewer line is
allowed. It is recommended that a PVC cement not be used so that the drain line can be
easily cleaned in the future.
IMPORTANT: DO NOT INSTALL AN EXTERNAL TRAP. DOING SO CAN CAUSE
IMPROPER DRAINAGE OF THE CONDENSATE AND RESULT IN FLOODING WITH-
IN THE UNIT.
The unit’s internal PVC drain line included a 3/16” hole on top of the line near the bulk
-
head to relieve negative pressure and allow proper drainage in the event of a dried out
trap. If condensate is running out of this hole during cooling operation, check for obstruc-
tions or double-trap in the drain line.
