Installation
Step 2-1 Attaching the mounting
bracket to the wall
1 Hold the mounting bracket against the wall at the
selected installation position (Step1-1 on page 6),
making sure that the screw holes align with the center of
the studs in the wall. If the screw locations do not align
with the studs, use wall anchors.
CAUTION
• The recommended best practice is to attach the
mounting bracket directly to the studs in the wall. If
you did not find a suitable location with studs (in Step
1-1 on page 6), or if the wall is concrete, you must
use wall anchors of a suitable type and weight capacity,
and install them according to the manufacturer’s
instructions. Failure to do so may cause the material
surrounding the joints to crumble over time and the
screws to be loosened and stripped. This may result
in the unit falling from the wall, which could cause
physical injury or equipment damage.
2 Using a level, make sure that the mounting bracket is
level, then mark the location of the screw holes on the
wall.
3 If using wall anchors, install them at the screw hole
positions, following the manufacturer’s instructions.
4 Using six field-supplied mounting screws and anchors (if
applicable), attach the bracket to the wall.

Step 2-2 Drilling the wall penetration
1 Determine the position of the hole through which the
piping bundle (consisting of power and communication
cables, refrigerant pipes, and the drain hose) will pass.
Consider the following:
‐The hole inner diameter must be 65 mm.
‐The recommended hole location is behind the unit
so that the hole and the piping bundle will not
be visible in the room. The minimum distances
between the hole and the mounting bracket are:
a

Model a b c
AC026/035TNXDKG 165 305 416
AC052/071TNXDKG 150 305 650.5
‐If the hole cannot be positioned behind the unit,
find a position as close to the unit as possible. The
piping bundle that exits the unit and extends to the
hole will need to be attached to the wall and will be
visible inside the room.
‐In relation to the bracket shown above, the unit
is shipped with the drain hose connection on the
right, the drain hose exits the unit on the left, and
the refrigerant pipes are bent to exit on the left.
Thus, positioning the hole to the left requires the
least effort. If you position the hole to the right
or below the unit, you will need to move the drain
hose connection to the left and bend the pipes so
that the hose and pipes exit to the right or bottom.
See the figure in step 3 on page 9.

NOTE
• The left, right, or bottom exit will only be used if the
hole is not positioned behind the unit.
Step 2-3 Connecting the refrigerant
pipes
Connect indoor and outdoor units with field-supplied copper
pipes by means of flare connections. Use insulated seamless
refrigeration grade pipe only, (Cu DHP type according to
ISO1337), degreased and deoxidized, suitable for operating
pressures of at least 4200 kPa and for burst pressure of at
least 20700 kPa. Under no circumstances must sanitary type
copper pipe be used.
IMPORTANT
• When installing the unit, always connect the
refrigerant pipes first, followed by the electrical cables.
For disassembly, always disassemble the electric cables
before the refrigerant pipes.
Two short refrigerant pipes are already attached to the air
conditioner:
• The smaller-diameter pipe is for the high-pressure,
two-phase refrigerant.
• The larger-diameter pipe is for the low-pressure
refrigerant vapor.

In Step 2-2, step 3 you determined the exit position for the
piping bundle. The unit has three knockouts available forthe
left, right, and bottom exits. When the bundle exits directly
from the rear, none of the knockouts are used.
1 If the pipes will exit directly from the rear, skip to step 3.
Otherwise, cut out the appropriate knockout piece (left,
right, or bottom).
2 Use a razor knife to clean the cut edges (flashing).
3 The left exit is the only position that does not require
bending the pipes. For other positions, bend the pipes so
that they will exit in the selected exit position.
‐The bending radius should be greater than 100 mm.
‐Bend the smaller pipe gradually to prevent kinking.
The larger pipe has a preinstalled spring bender to
prevent kinking.
‐Make sure that the pipes do not protrude from the
back of the unit in a way that will make it difficult to
attach the unit to the mounting bracket.
‐For right and bottom exits, pull the pipes out through
the selected knockout opening. For left exits, the
piping connections will be made in the service space
behind the indoor unit (under the cover panel).

NOTE
• If you are using the right rear exit, the pipes should
be long enough to extend through the wall without
needing to connect the line set first. It may be easier
to connect the line set outside of the building, after
you have bundled the pipes and cables and passed the
bundle through the wall. In this case, do not connect
the line set now. Instead, complete Step 2-4 through
Step 2-7, then go outside and connect the line set as
described below.
4 Slowly remove the protective caps on the refrigerant pipe
connections to relieve the nitrogen holding charge.
5 Connect the line set to each pipe.

ø 15.88 68–82
CAUTION
• Tighten the flare nuts only to the specified torque. If
a flare nut is overtightened, the flare face may crack,
causing refrigerant leakage.
8 Do not box in or cover the pipe connections. Make sure
that the connections are accessible for testing later in the
installation process and for future servicing.
9 Tape over the end of the pipes so that debris will not enter
the piping when it is passed through the wall. The pipes
will be insulated later in the installation process.
Step 2-4 Connecting the power and
communication cables
If using a multi system, install as described in the
installation manual supplied with the outdoor unit.
WARNING
• Do not modify the power cable in any way. Doing so may cause
electric shock orfire due to poorconnection, poor insulation, or
current limit override. Make sure to complywith the technical
standards of electrical installations and the wiring regulations
in the local area.
• This appliance must be properly grounded. Do not ground the
appliance to a gas pipe, plastic waterpipe, or telephone line.
Failure to comply may result in electric shock, fire, and explosion.
• Make sure that cabling is not subject to wear, corrosion,
excessive pressure, vibration, sharp edges, or adverse
environmental effects. Take into account the effects of aging or
continual vibration from sources such as compressors or fans.

Leak test
LEAK TESTWITH NITROGEN (before opening valves)
In order to detect basic refrigerant leaks, before recreating
the vacuum and recirculating the R-32, it’s responsible of
installer to pressurize the whole system with nitrogen (using a
pressure regulator) at a pressure above 4.1MPa (gauge).
LEAK TESTWITH R-32 (after opening valves)
Before opening valves, discharge all the nitrogen into the
system and create vacuum. After opening valves check leaks
using a leak detectorfor refrigerant R-32.

Emergency Temperature Output (ETO) function
CAUTION
• In order to deploy the ETO function, the MIM-B14, an external contact interface module, must be installed in each
indoor unit.
‐The ETO is a concept of emergency operation of indoor units. If the indoor unit 1 (main indoor unit) stops because of
an error, the indoor unit 2 (sub indoor unit) starts to operate.
‐Basically, the indoor unit 2 operates in the previous mode. [For the first time operation, it starts in 24 °C (75 °F)
Auto mode.]
‐To set more detailed operation conditions for the indoor unit 2, use the S-net Pro.
