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.

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 shut-down, caus‐

 

 

ing refrigerant slugging and possible compressor

 

 

damage at start-up.

 

 

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 FILTER-DRIER

 

 

Outdoor units are shipped with an appropriate filter-drier

 

 

for installation in the liquid line. Leave the plugs in the tube

 

 

ends until the filter-drier is installed. The optimal location

 

 

for the filter-drier is close to the indoor coil. Heat pump

 

 

filter-driers are “bi-flow” type. Either end can be pointed
