Carrier 40QA024-060 specifications Connect Condensate Drain Line

f.Refer to the outdoor unit Installation, Start-Up and Service Instructions for additional information.

g.Install a factory-supplied filter drier near the out- door unit. On heat pump systems, a bi-flow filter drier must be used.

3.Insulate and caulk wall openings to reduce air infiltra- tion and refrigerant pipe vibrations on structure.

4.Evacuate piping, if necessary. If either refrigerant pip- ing or the indoor coil is exposed to atmospheric condi- tions, it must be evacuated to 1000 microns to eliminate contamination and moisture in the system.

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 nominal ID of 3/4 in. to connect at drain line. Use pipe insulation 1/4-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 1/4-in. per ft.

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 mate- rial such as polyurethane or neoprene.

6.Install an external trap at the end of the condensate line.

NOTE: Should the installation require one, a conden- sate pump may be ordered as a field-installed accessory.
