INSTALLING THE DRAIN HOSE
Install the drain pipe with downward gradient (1/50 to 1/100) and so there are no rises or traps in the pipe.
Use general hard polyvinyl chloride pipe (VP25) (outside diameter 38 mm)
During installation of the drain pipe, be careful to avoid applying pressure to the drain point of the unit.
When the pipe is long, install supporters.
Do not perform air bleeding.
Always heat insulate (8mm or over thick) the indoor side of the drain pipe.
