indoor unit with insulation material and secure it with narrow 
vinyl tape and wide vinyl tape.
   If you want to connect an additional drain hose, the end of the 
drain hose outlet should be routed above the ground. Secure 
the drain hose appropriately.
b.   In cases where the outdoor unit is installed below the indoor 
unit level: 
   Wrap the piping, drain hose and connecting cable from the 
bottom to the top. Secure the wrapped piping along the 
exterior wall using saddle or equivalent.
