12.1.3.1.2 To drill a hole in the wall and install a sleeve of piping
1 Insert the piping sleeve to the hole.
2 Fix the bushing to the sleeve.
3 Cut the sleeve until it extrudes about 15 mm
from the wall.
CAUTION
When the wall is hollow, please be sure to use the sleeve for tube
ass'y to prevent dangers caused by mice biting the connecting cable.
4 Finish by sealing the sleeve with putty or
caulking compound at the final stage.
12.1.3.1.3 Drain piping
1 Use commercial rigid polyvinyl chloride pipe (general VP 20 pipe, outer diameter 26mm, inner diameter
20mm) for the drain pipe.
2 The drain hose (outer diameter 18mm at connecting end, 270mm long) is supplied with the indoor unit.
Prepare the drain pipe picture below position.
3 The drain pipe should be inclined downward so that water will flow smoothly without any accumulation.
(Should not be trap.)
4 Insert the drain hose to this depth so it won't be pulled out of the drain pipe.
5 Insulate the indoor drain pipe with 10mm or more of insulation material to prevent condensation.
6 Remove the air filters and pour some water into the drain pan to check the water flows smoothly.
