transmission between the tubing and the foundation or wall.
Along floor or ceiling joists, suspend refrigerant lines so that they do not contact the building structure, water
pipes, or ductwork. Use insulated or suspension type hangers. Metal straps must be at least 1” wide to avoid cutting into the tube insulation. Keep the liquid and suction lines separate. Refer to Figure 4.

!CAUTION
UNIT OPERATION HAZARD
Failure to follow this caution may result in improp‐ er product operation.
Do not bury more than 36” of line set underground. Refrigerant may migrate to cooler buried section during extended periods of unit
If ANY section of the line set is buried under‐ ground, provide a minimum 6” vertical rise at the service valve.
D. OUTDOOR UNIT HIGHER THAN INDOOR UNIT
Proper oil return to the compressor should be maintained with suction gas velocity. If velocities drop below 1500 fpm (feet per minute), oil return will be decreased. To maintain suction gas velocity, do not upsize vertical suction risers.
NOTE: If there is more than 20 feet vertical separation between outdoor and indoor units, refer to the Long Line Application Guidline document for additional instructions.
E. LIQUID LINE
Outdoor units are shipped with an appropriate
