intended for, or to include all details for, a specific installation.
4. Install field-supplied disconnect switch in accordance with all local and national electri-
cal codes.
5. Liquid line solenoid valves (solenoid drop control) are not required but are recom-
mended to prevent refrigerant migration to the compressor.
6. Factory-supplied accumulator not shown.
7. Dual-circuit piping shown. Single-circuit piping is similar but would only have one suc-
tion line and one liquid line.
8. A field-supplied, 5 to 15% bleed port TXV is required for every application.
9. Sight glass, LLSV, and filter drier are field supplied.
10. Long line length check valves are required for liquid line installation on all linear line
length applications of more than 100 ft (30.5 m). For any 025-030 size dual-circuit unit
application where evaporator is located higher than the condensing unit, check valves
are required for linear line length above 55 ft (16.8 m).
