Drilling a wall hole and installing wall embedded pipe

• For metal frame or metal board walls, be sure to use a wall embedded
pipe and wall hole cover in the feed-through hole to prevent possible heat,
electrical shock, or fire.
• Be sure to caulk the gaps around the pipes with caulking material to prevent
water leakage.
1) Drill a feed-through hole with a φ2-9/16 inch (65mm) diameter through the
wall at a downward angle toward the outside.
2) Insert a wall embedded pipe into the hole.
3) Insert a wall hole cover into wall pipe.
4) After completing refrigerant piping, wiring, and drain piping, caulk the pipe
hole gap with putty.

Drain piping

1) Use commercial rigid polyvinyl chloride pipe (general VP 20 pipe, outer diameter 1 inch (26mm), inner diameter 13/16
inch (20mm)) for the drain pipe.
2) The drain hose (outer diameter φ11/16 inch (φ18mm) at connecting end, 8-11/16 inch (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 3/8 inch (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.
3-15/16 (100)
CAUTION
Use polyvinyl chloride adhesive agent for gluing. Failure to do so may cause water leakage.
