2. Drilling a wall hole and installing wall embedded pipe
WARNING
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, electric shock, or re.
• Be sure to caulk the gaps around the pipes with caulking material to prevent
condensation.
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.

3. Drain piping
• The drain pipe should be inclined downward so that water will ow smoothly
without any accumulation. (Should not be trap.)
No trap is permitted.
The drain pipe should
be inclined downward.
Do not put the end
of the hose in water.
• 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.
• The drain hose (outer diameter φ11/16 inch (φ18mm) at connecting end, 8-11/16 inch (220mm) long) is supplied with the
indoor unit.
1) Perform drain piping work as outlined in the gure. (See Fig. 1)
• Insert the
C
drain hose into the socket of the drain pan. (See Fig. 2)
Fully insert the drain hose until it adheres to a seal of the socket.
2) Insulate the indoor drain pipe with 3/8 inch (10mm) or more of insulation material to prevent condensation.
3) Remove the air lters and pour some water into the drain pan to check the water ows smoothly.
