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 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 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.
