1. Symbols are electrical representation only.

2. Compressor and fan motor furnished with inherent thermal protection.

3. To be wired in accordance with National Electric N.E.C. and local codes.

4. N.E.C. class 2, 24 V circuit, min. 40 VA required, 60 VA on units installed with LLS.

5. Use copper conductors only. Use conductors suitable for at least 75°C (167°F).

6. Connection for typical cooling only thermostat. For other arrangements see installation instructions.

7. If indoor section has a transformer with a grounded secondary, connect the grounded side to the BRN/YEL lead.

8. When start capacitor and relay are installed, start thermistor is not used.

9. CH not used on all units.

10. If any of the original wire, as supplied, must be replaced, use the same or equivalent wire.

11. Check all electrical connections inside control box for tightness.

12. Do not attempt to operate unit until service valves have been opened.

13. Do not rapid cycle compressor. Compressor must be off 3 minutes to allow pressures to equalize between high and low side before starting.

14. It is imperative to connect 3−phase field power to unit with correct phasing. If phasing is reversed, interchange any two of the three power connections on field side.

15. Wire not present if HPS, LPS or CTD are used.

16. Not for interrupting current.
