LG ARUM072BTE5 Installation Manual page 39

Job site conditions may require routing utilities—including the refrigerant
piping, condensate pipe, and electrical wiring—under the unit base. If
job site conditions warrant, consider adding mounting rails under the
unit. The unit may need to be elevated above the floor to provide the
necessary slope for proper condensate draining on long pipe
installations.
Anchoring the Outdoor Unit
• Outdoor unit support(s) must be at least ≥4 inches wide and ≥8
inches high.
• Include anti-vibration material chosen by the acoustics engineer.
• If not otherwise directed by the structural engineer or local codes,
use 7/8 inch or 1/2 inch diameter J-bolts inserted at least 3 inches
deep into the supports.
• Use a hexagon nut with a lock washer.
