SYSTEM DESIGN SUMMARY

1. Intended for outdoor installation with free air inlet and outlet. Outdoor fan external static pressure available is less than 0.01- -in. wc.
2. Minimum outdoor operating air temperature without low- -ambient operation accessory is 55_F (12.8_C).
3. The maximum outdoor operating ambient in cooling mode is 125_F (51.67_C) when operating voltage is 230v. For 208v
applications, the maximum outdoor ambient is 120_F (48.9_C).
4. For reliable operation, unit should be level in all horizontal planes.
5. 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 distribut-
or.
6. 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).
7. Use only copper wire for electric connection at unit. Aluminum and clad aluminum are not acceptable for the type of connector
provided.
