■Installation
Indoor unit
1. Do not have any heat or steam near the unit.
2. Select a place where there are no obstacles
in front of the unit.
3. Make sure that condensation drainage can be
conveniently routed away.
4. Do not install near a doorway.
5. Ensure the spaces indicated by arrows from
the wall, ceiling, fence or other obstacles.
6. Use a stud finder to locate studs to prevent
unnecessary damage to the wall.
Outdoor unit
1. If an awning is built over the unit to prevent
direct sunlight or rain exposure, make sure
that heat radiation from the condenser is not
restricted.
2. Ensure that the spaces indicated by arrows
around front, back and side of the unit.
3. Do not place animals and plants in the path
of the warm air.
4.Take the air conditioner weight into account
and select a place where noise and vibration
are minimum.

Installation of Indoor, Outdoor Unit
The wall you select should be strong and solid
enough to prevent vibration
1. Mount the installation plate on the wall with
type "A" screws. If mounting the unit on a
concrete wall, use anchor bolts.
• Mount the installation plate horizontally by
aligning the centerline using a level.
2. Measure the wall and mark the centerline. It
is also important to use caution concerning
the location of the installation plate-routing
of the wiring to power outlets is through the
walls typically. Drilling the hole through the
wall for piping connections must be done
safely.

Flaring Work and Connection of Piping
Flaring Work and Connection of Piping
Flaring work
Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the
following procedure.
Cut the pipes and the cable.
1. Use the piping kit accessory or the pipes
purchased locally.
2. Measure the distance between the indoor and
the outdoor unit.
3. Cut the pipes a little longer than measured
distance.
4. Cut the cable 1.5m longer than the pipe length.
Burrs removal
1. Completely remove all burrs from the cut cross
section of pipe/tube.
2. Put the end of the copper tube/pipe in a
downward direction as you remove burrs in
order to avoid dropping burrs into the tubing.
Putting nut on
• Remove flare nuts attached to indoor and
outdoor unit, then put them on pipe/tube having
completed burr removal.
(not possible to put them on after flaring work)
Flaring work
• Carry out flaring work using flaring tool as shown
below.
• Firmly hold copper pipe in a die in the dimension
shown in the table above.
