Wall-through hole
1.
Make a hole with an electric
hammer or a water drill at the
predetermined position on the
wall for piping, which shall slant
outwardly by 5–10°.
2.
To protect the piping and the
cables from being damaged
running through the wall, and from
the rodents that may inhabit in the
hollow wall, a pipe protecting ring
shall be installed and sealed with
putty.
Note:
Usually, the wall hole is Ø 60 mm – Ø 80 mm. Avoid pre-buried power
wire and hard wall when making the hole.
Route of pipeline
Depending on the position of the unit, the piping may be routed sideway from the
left or the right (Figure 1), or vertically from the back (Figure 2)(depending on the
pipe
length of the indoor unit). In the case of sideway routing, cut off the outlet cutting
stock of the opposite side.
