5. INSTALLING DRAIN HOSE
]
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.
