CAUTION
• Install the drain hose in accordance with the instructions
in this Installation Manual and keep the area warm
enough to prevent condensation. Problems with the
piping may lead to water leaks.
Use general hard polyvinyl chloride pipe and connect it with
adhesive (polyvinyl chloride) so that there is no leakage.
Always heat insulate the indoor side of the drain hose.
Use a drain pipe that matches the size of the drain hose.
• Do not perform a rise, trap and air bleeding.
• Provide a downward gradient (1/100 or more).
• Provide supporters when long pipes are installed.
• Use an insulation material as needed, to prevent the pipes
from freezing.
• Install the pipes in a way that allows for the removal of the
control box.
