8f. Refer to the outdoor unit Installation, Start-Up andService Instructions for additional information.g. Install a factory-supplied filter drier near the out-door unit. On heat pump systems, a bi-flow filterdrier 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 toeliminate contamination and moisture in the system.Step 5 — Connect Condensate Drain Line —Observe all local sanitary codes when installing condensatedrains. Refer to Fig. 3 and 14 for drain pipe connection fromindoor unit.1. Use hard polyvinyl chloride (PVC) pipe material withnominal ID of 3/4 in. to connect at drain line. Use pipeinsulation 1/4-in. thick, such as Armaflex insulation, onexposed piping inside the conditioned space.2. To ensure regular flow of condensate water, the drainpipe should be pitched toward an open drain or sumpat 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 throughhole (Fig. 15).NOTE: Do not fasten nylon wire ties tight enough todeform the insulation, as this affects its performance.5. Insulate condensate drain line(s) that are located in orabove an occupied area with a condensate-proof mate-rial such as polyurethane or neoprene.6. Install an external trap at the end of the condensateline.NOTE: Should the installation require one, a conden-sate pump may be ordered as a field-installedaccessory.Table 4A — Piston and Charge Combinations — Cooling Only SystemsTable 4B — Piston and Charge Combinations — Heat Pump Systems*Size 060 indoor heat pump systems use a TXV (thermostatic expansion valve), part no.
