Boring a wall hole and installing wall embedded pipe
• For walls containing metal frame or metal board,
be sure to use a wall embedded pipe and wall
cover in the feed-through hole to prevent water
leakage.
• Be sure to caulk the gaps around the pipes with
caulking material to prevent water leakage.
1. Bore a feed-through hole of 55mm in the wall so
it has a down slope toward the outside.
2. Insert a wall pipe into the hole.
3. Insert a wall cover into wall pipe.
4. After completing refrigerant piping, wiring, and
drain piping, caulk pipe hole gap with putty.
Drain piping
• Use commercial regid polyvinyl chloride general VP 20 pipe, outer diameter 26mm, inner diameter 20mm
for the drain pipe.
• The drain hose (outer diameter 18mm at connecting end, 220mm long)is supplied with the indoor unit.
Prepare the drain pipe picture below position.
• The drain pipe should be inclined downward so that water will flow smoothly without any accumulation.
(Should not be trap.)
• Insert the drain hose to this depth so it won’t be pulled out of the drain pipe.
• 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.
