3-3. Wall embedded piping
Follow the instructions given under left-back piping.
1) Insert the drain hose to this depth so it won’t be pulled
out of the drain pipe.
3-4. Bottom or left side piping
1) Cut off the pipe port cover with a copping saw.
• For bottom piping: On the bottom of the front grille
• For left side piping: On the side cover (front grille side and unit side)
Apply the blade of the copping saw to the notch, and cut off the pipe port cover along the uneven inner surface.
2) After cutting off the pipe port cover, perform filing.
Remove the burrs along the cut section using a half round needle file.
3) Wrap the refrigerant pipes and drain hose together with insulation tape.
Then, insert the drain hose and refrigerant pipes into the wall hole after inserting them into the cut out piping hole
opened.
