BURYING REFRIGERANT LINES
If burying refrigerant lines can not be avoided, use the following checklist.
1. Insulate liquid and suc�on lines separately.
2. Enclose all underground por�ons of the refrigerant lines in waterproof material (conduit or pipe) sealing the ends where
tubing enters/exists the enclosure.
3. If the lines must pass under or through a concrete slab, ensure lines are adequately protected and sealed.
