Step 3 — Field Fabricate Ductwork — Secure all
ducts to building structure. Use flexible duct connectors
between unit and ducts as required. Insulate and weather­
proof all external ductwork, joints and roof openings
with flashing and mastic in accordance with applicable
codes.
Ducts passing through an unconditioned space must
be insulated and covered with a vapor barrier.
A minimum clearance is not required on 50DP,
DPE012,014 and 50DP016 units. The 50DP020 units
with electric heat require one-in. clearance the first 24 in.
of ductwork.
Outlet grilles must not lie directly below unit discharge.
Step 4 — Make Unit Duct Connections — Unit
is shipped for through-the-bottom duct connections.
Ductwork openings are shown in Fig. 1 and 4. Duet
connections are shown in Fig. 5. Field-fabricated con­
centric ductwork may be connected as shown in Fig. 6 and
7. Attach all ductwork to roof curb and roof curb base-
pans. Refer to installation instructions shipped with
accessory roof curb.

half coupling is provided inside unit evaporator section
for condensate drain connection. An 8-1/2in. x 3/4-in.
diameter and 2-in. x 3/4-in. diameter pipe nipple coupled
to standard 3/4-in. diameter elbows provide a straight
path down through holes in unit base rails (see Fig. 9).
A trap at least 4 in. deep must be used and must be pro­
tected against freeze-up.
