Step 5 - Connect Condensate Drain Line - Bryant 619CNF Installation, Start-Up And Service Instructions Manual

3. Insulate and caulk wall openings to reduce air infil-
tration and refrigerant pipe vibrations on structure.
4. Evacuate piping, if necessary. If either refrigerant
piping or the indoor coil is exposed to atmospheric
conditions, it must be evacuated to 1000 microns to
eliminate contamination and moisture in the system.
V. STEP 5 — CONNECT CONDENSATE DRAIN LINE
Observe all local sanitary codes when installing condensate
drains. Refer to Fig. 3 and 14 for drain pipe connection from
indoor unit.
1. Use hard polyvinyl chloride (PVC) pipe material with
3
nominal ID of / in. to connect at drain line. Use pipe

insulation / -in. thick, such as Armaflex insulation,

on exposed piping inside the conditioned space.
2. To ensure regular flow of condensate water, the drain
pipe should be pitched toward an open drain or sump
at a downward slope of at least

3. Attach plate with screws under piping hole.
4. Attach drain pipe with nylon wire tie passing through
hole (Fig. 15).
NOTE: Do not fasten nylon wire ties tight enough to
deform the insulation, as this affects its performance.
5. Insulate condensate drain line(s) that are located in
or above an occupied area with a condensate-proof
material such as polyurethane or neoprene.
6. Install an external trap at the end of the condensate
line.
NOTE: Should the installation require one, a
condensate pump may be ordered as a field-installed
accessory.
