2.1 Unit Dimensions and Weight
When mounting the outdoor unit on a roof, be sure the roof will support the unit’s weight.
Properly selected isolation is recommended to alleviate sound or vibration transmission to the building structure.

2.2 Refrigerant Piping Limits
1. The maximum length of refrigerant lines from outdoor to indoor unit should NOT exceed sixty (60) feet.
2. The maximum vertical change should not exceed sixty (60) feet.
3. Service valve connection diameters are shown in Table 5.1.
Note: For line lengths greater than sixty (60) feet, Refer to Refrigerant Piping Application Guide, SS-APG006F-EN,

2.3 Suggested Locations for Best Reliability
Ensure the top discharge area is unrestricted for
at least five (5) feet above the unit.
Three (3) feet clearance must be provided in
front of the control box (access panels) and any
other side requiring service.
Do not locate close to bedrooms as operational
sounds may be objectionable.
Position the outdoor unit a minimum of 12” from
any wall or surrounding shrubbery to ensure
adequate airflow.
Outdoor unit location must be far enough away
from any structure to prevent excess roof runoff
water from pouring directly on the unit.
