Features and Benefits

• Swept Wing Fan Technology1 : Features quieter operation and improved unit acoustics
  Two-Stage Scroll Compressor2 : Features two speeds (high and low) of cooling and heating, providing more precise temperature control, lower humidity and greater efficiency when compared to single stage compressors

• Inverted Reversing Valve: Allows for faster heat transfer with gravity assist shifting and reduced joint stress for increased reliability

• Expanded Valve Space: 3 in. – 4 in. – 5 in. service valve space—provides a minimum working area of 27-square inches for easier access

• Triple Service Access: 15 in. wide, industry leading corner service access, two fastener, removeable corner and individual louver panels—makes repairs easier and faster

1 Does not apply to the 3.5 and 4 Ton

General Data

Electrical Data

¹  Refrigerant charge sufficient for 15 ft. length of refrigerant lines. For longer line set requirements see the installation instructions for information about set length and additional refrigerant charge required.
²HACR type circuit breaker of fuse.
³Refer to National Electrical Code manual to determine wire, fuse and disconnect size requirements.

Accessories

*Bi-flow kits are required when installing a liquid line solenoid on a heat pump.

Weighted Sound Power Level (dBA)

NOTE: Tested in accordance with AHRI Standard 270-08 (not listed in AHRI)

Unit Dimensions

CLEARANCES

NOTE: NUMBERS IN () = mm
IMPORTANT : When installing multiple units in an alcove, roof well or partially enclosed area, ensure there is adequate ventillation to prevent re- circulation of discharge air.

Control Wiring

Application Guidelines

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 operation air temperature for cooling mode without low-ambient operation accessory is 55°F (12.8°C).
3. Maximum outdoor operating air temperature is 125°F (51.7°C).
4. For reliable operation, unit should be level in all horizontal planes.
5. Use only copper wire for electric connections at unit. Aluminum and clad aluminum are not acceptable for the type of connector provided.
6. Do not apply capillary tube indoor coils to these units.
7. Factory-supplied filter drier must be installed.

Refrigerant Line Size Information

NOTES:

1. *Do not exceed 200 ft linear line length.
2. *Do not exceed 100 ft vertical separation if outdoor unit is above indoor unit.
3. *Always use the smallest liquid line allowable to minimize refrigerant charge.
4. *Applications shaded in light gray indicate capacity multipliers between 0.90 and 0.96 which are not recommended, but are allowed.
5. *Applications shaded in dark gray are not recommended due to excessive liquid or suction pressure drop.
