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.
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, 220mm 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.
Caution
Use polyvinyl chloride adhesive agent for gluing. Failure to do so may cause water leakage.
