make sure that it is installed, operated, and stored it
in a room whose floor area is larger than the minimum
required floor area specified in the following table:

• IMPORTANT: it's mandatory to consider either the
table above or taking into consideration the local
law regarding the minimum living space of the
premises.
• Minimum installation height of indoor unit is 0.6 m
for floor mounted, 1.8 m for wall, 2.2 m for ceiling.
CAUTION
• 3 m as minimum pipe length: It will reduce noise and
vibration.
• Tighten the nuts to the specified torques.
If overtightened, the nuts could be broken so
refrigerant may leak.
• Protect or enclose refrigerant tubing to avoid
mechanical damage.
NOTE
• The appearance of the unit may be different from the
diagram depending on the model.

- It could take maximum 60 minutes to operate for the
protection of the compressor,if the outdoor temperature
is below -5°C.
Step 7 Optional: Cutting and flaring
the pipes
1 Make sure that you have the required tools available.
(pipe cutter, reamer, flaring tool, and pipe holder)
2 If you wish to shorten the pipes, cut it with a pipe
cutter, taking care to ensure that the cut edge remains
at a 90° angle with the side of the pipe. Refer to the
illustrations below for examples of edges cut correctly
and incorrectly.
90°
3 To prevent any gas from leaking out, remove all burrs
at the cut edge of the pipe, using a reamer.
4 Slide a flare nut on to the pipe and modify the flare.
