Section 2. Unit Location Considerations
2.1 Unit Dimensions and Weight
2.2 Refrigerant Piping Limits
1. The maximum TOTAL length of refrigerant lines from outdoor to indoor unit should NOT exceed 150 feet
(including lift).
2 . The maximum vertical change should not exceed 50 feet.
3. Service valve connection diameters are shown in Table 5.1.
Note: For other line lengths, Refer to Refrigerant Piping Application Guide, SS-APG006F-EN, or Refrigerant
Piping Software Program.
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.

2.3 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.
