SYSTEM DESIGN SUMMARY

1. Intended for outdoor installation with free air inlet and outlet. Outdoor fan external static pressure available is less than .01--in. wc.

2. Minimum outdoor operating air temperature without low--ambient operation accessory is 55_F (12.8_C).

3. Maximum outdoor operating air temperature for cooling mode is 125_F (51.7_C).

4. Minimum outdoor operating air temperature for heating mode is –30_F (–34.4_C).

5. Maximum outdoor operating air temperature for heating mode is 66_F (18.9_C).

6. For reliable operation, unit should be level in all horizontal planes.

7. For interconnecting refrigerant tube lengths greater than 80 ft (23.4 m) and/or elevation differences between indoor and outdoor units greater than

20 ft (6.1 m), consult Residential Piping and Longline Guideline and Service Manual available from equipment distributor.

8. If any refrigerant tubing is buried, provide a 6 in. (152.4 mm) vertical rise to the valve connections at the unit. Refrigerant tubing lengths up to 36

in. (914.4 mm) may be buried without further consideration. Do not bury refrigerant lines longer than 36 in. (914.4 mm).

9. Use only copper wire for electric connection at unit. Aluminum and clad aluminum are not acceptable for the type of connector provided.

10. Do not apply capillary tube indoor coils to these units.

11. Factory--supplied filter drier must be installed.
