INSTALLATION
Location of anchor bolt
• Installation foot (Location of anchor bolt)
Foundation for Installation
• Fix the unit tightly with bolts as shown below so that unit will not fall
down due to earthquake or gust.
• Use the H-beam support as a base support
• Noise and vibration may occur from the floor or wall since vibration is
transferred through the installation part depending on installation sta-
tus. Thus, use anti-vibration materials (Anti-vibration pad) fully (The
base pad shall be more than 200 mm).

Ⓐ Ensure that the corner part can be securely mounted. Otherwise,
the support for installation may be bent.
Ⓑ Obtain and use the M10 anchor bolt.
Ⓒ The corner was not properly mounted.
Ⓓ Outdoor unit (Insert the cushion pad between outdoor unit and base
support to ensure that anti-vibration may be done in a wide area)
Ⓔ Pipe and wiring space (in case of piping and wiring on the floor sur-
face)

WARNING
!
• Be sure to install unit in a place strong enough to withstand its
weight.
Any lack of strength may cause unit to fall down, resulting in a
personal injury.
• Have installation work in order to protect against a strong wind
and earthquake. Any installation deficiency may cause unit to
fall down, resulting in a personal injury.
• Especially take care for support strength of the floor surface,
water drain processing (processing of water flown out from the
outdoor unit during operation) and paths of the pipe and wiring
when making a base support.
• Don't use a tube or pipe for water drain in the base pan and per-
form water drain processing by using the drain path.
VWater drain may not be done due to freezing of a tube or pipe.
Preparation of Piping
Main cause of gas leakage is defect in flaring work. Carry out correct
flaring work in the following procedure.
Cut the pipes and the cable
- Use the accessory piping kit or the pipes purchased locally.
- Measure the distance between the indoor and the outdoor unit.
- Cut the pipes a little longer than measured distance.
Copper
tube
90°
Burrs removal
- Completely remove all burrs from the cut cross section of pipe/tube.
- Put the end of the copper tube/pipe to downward direction as you re-
move burrs in order to avoid to let burrs drop in the tubing.
Point down

- Carry out flaring work using flaring tool as shown below.
