Step 4 - Make Unit Duct Connections.6; Step 5 - Trap Condensate Drain - Carrier 50DPE014 Installation, Start-Up And Service Instructions Manual

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 50DPE014
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. Duct
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.

Step 5 — Trap Condensate Drain
— See Fig. 4
and 8 for drain location. Plug is provided in drain hole
and must be removed when unit is operating. One 3/4-in.
half coupling is provided inside unit evaporator section
for condensate drain connection. An 8-1/2 in. 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.
NOTE: Do not drill in this area, damage to basepan may result
in water leak
