•• The indoor and outdoor units must be installed in
compliance with minimum clearances to ensure that
both units are accessible from both sides and can be
maintained or repaired. Insufficient clearance may
reduce product performance, generate excessive noise,
and reduce the life of some unit components.
Indoor unit location requirements
WARNING
•• Do not install the unit in a humid, oily, or dusty location
or in a location exposed to direct sunlight, water, or rain.
•• Make sure that the wall can support the unit weight.
Examine the area that the customer wants to be air
conditioned. Consider the following:
•• What wall location will meet minimum clearances and
provide optimal product performance?
•• Will the wall provide adequate support for the unit
weight (wall with stud construction or concrete)? If
applicable, where are the studs?
•• Where will you place the wall penetration for
routing the piping bundle (consisting of power and
communication cables, refrigerant pipes, and the drain
hose) through the wall to the outdoor unit? Will the
hole intersect any plumbing or wires in the wall?
•• Is the location as close as possible to where the outdoor
unit will be installed, to minimize the length of piping
and cables?
•• Will the condensate drain inside the room, through the
wall penetration to the outdoor unit, or be connected to
a condensate pump?
NOTE
IMPORTANT
Minimum clearances for the indoor unit

•• This manual covers a typical gravity‑drain installation
where the drain hose is routed to the outdoor unit
through a hole in the wall.
Preparation
Outdoor unit location requirements
Installation Guide at the seashore
Examine the area where the outdoor unit could be located.
Consider the following:
Make sure to follow below guides when installing at the
seashore.
•• What location will meet minimum clearances and
provide optimal product performance?
1
•• Is there an existing level and hard foundation, such as
a concrete pad, that will support the unit weight and
produce minimal vibration? Installation on uneven
ground may result in abnormal vibrations, noise, or
problems with the unit.
Do not install the product in a place where it is directly
exposed to sea water and sea breeze.
‐‐
Make sure to install the product behind a structure
(such as building) that can block see breeze.
‐‐
Even when it is inevitable to install the product in
seashore, make sure that product is not directly
exposed to sea breeze by installing a protection wall.
•• Does the unit need to be mounted on the wall?
2
•• Where are the dedicated circuit breaker and disconnect
switch located? How will you connect them to the unit?
Consider that the salinity particles clinging to the external
panels should be sufficiently washed out.
3
Because the residual water at the bottom of the outdoor
unit significantly promotes corrosion, make sure that the
slope does not disturb drainage.
•• How will you route the piping bundle from the indoor
unit? Is the location as close as possible to where the
indoor unit will be installed, to minimize the length of
piping and cables?
‐‐
Keep the floor level so that rain does not accumulate.
‐‐
Be careful not to block the drain hole due to foreign
substance.
•• Will the unit be sheltered from the wind? In a
high‑wind area, you may need to build a protective
fence around the unit.
4
•• Where will the condensate drain?
When product is installed in seashore, periodically clean it
with water to remove attached salinity.
5
Make sure to install the product in a place that provides
smooth water drainage. Especially, ensure that the base
part has good drainage.
6
If the product is damaged during the installation or
maintenance, make sure to repair it.
7
Check the condition of the product periodically.
WARNING
•• The drain location must allow condensate to drain
properly and prevent ice from forming on the unit in
winter. If a block of ice falls from the unit, it may result
in death, serious injury, or property damage. Improper
or inadequate draining may result in water overflowing
and property damage.
Installation
CAUTION
•• Do not connect the drain hose to existing waste pipes
as odors may arise.
Installation on an exterior wall
If the outdoor unit must be installed on an exterior wall, you
will need an L‑bracket to support the unit. This bracket is not
included with the unit.
WARNING
•• The wall must be capable of supporting the weight
of both the L‑bracket and the outdoor unit. If the unit
falls, it may result in crushing, electric shock, fire, or
explosion that could cause death, severe personal
injury, or property damage.

Indoor Unit Installation
Step 2.1 Attaching the mounting bracket
to the wall
1
Hold the mounting bracket against the wall at the
selected installation position (Step 1.2 on page 5),
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.
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:
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
1.2 on page 5), 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.

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 12.

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.

In Step 2.2, step 3 you determined the exit position for the
piping bundle. The unit has three knockouts available for the
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.

Outdoor Unit Installation
Step 3.1 Mounting the outdoor unit
3
Level the unit, then use anchor bolts to secure it at the
four mounting points.
To promote proper condensate draining, the recommended
installation of the outdoor unit is elevated above the ground
on a mounting bracket attached to a concrete pad.
4
For installations in locations that require seismic or
hurricane tie downs, comply with local codes.
5
If the selected location is exposed to strong winds, install
a protective fence around the unit so that the fan can
operate correctly.
In areas where snowfall occurs, the unit must be mounted
above the snow line to allow for proper heating. Snow cannot
be allowed to collect on top of the unit. For promoting natural
drainage in a heavy snow fall area:
On a wall
•• Make space more 80 mm between the bottom of the
outdoor unit and the ground for installation. (Ensure
that the drained water runs off correctly and safely.)
•• Allow enough separation distance between the product
and the ground.

Step 4.3 Evacuating the system
CAUTION
•• Because the system does not have filter driers, you
must perform this triple evacuation procedure to
remove all noncondensables and moisture from the
system before charging. Failure to do so will result in
reduced performance and shorter equipment life.
The time required to perform each evacuation will depend on
the capacity (CFM) of the vacuum pump used.
1
Install a micron vacuum gauge to the larger liquid/vapor
line’s service port on the branch of a tee.
2
Install the red high‑side hose of an R-410A gauge
manifold set to the smaller liquid/vapor line’s service port
on the run of the tee.
3
Attach a vacuum pump to the common hose of the
manifold set.
4
To ensure optimal performance, verify that the vacuum
pump’s oil has been changed recently.
5
With the service port closed and the manifold gauge
open, start the vacuum pump and make sure that the
vacuum level drops below 4000 microns (as read on the
micron gauge). If it is difficult to achieve a proper vacuum,
a leak in the hoses is likely. Repair the leak(s) and/ or
check performance of vacuum pump, then repeat this
step.
Installation
6
Open the service port to connect the system to the
manifold.
7
Evacuate until 4000 microns is achieved, for at least 10
minutes.
8
Close the gauge manifold valve, shut off the vacuum
pump, and remove the common hose.
9
Connect the hose to the nitrogen pressure regulator and
bleed the hose by opening the end of the common hose
closest to the manifold.
10 Open the high-pressure manifold valve and slowly bring
the system pressure to atmosphere (50 kPa).
11 Close the manifold and nitrogen cylinder and remove the
common hose.
22 English
12 Reconnect the common hose to the vacuum pump.
Repeat steps 6 through 12, alternating between breaking
the vacuum with dry nitrogen and evacuating, until
system evacuation has occurred three times, to the
following vacuum levels:

Microns
First
4000
Second
2000
Third

13 After evacuating to at least 500 microns for the third
time, close the gauge manifold valve and wait 10 minutes,
making sure that the vacuum level in the system does not
decrease. If it does, a small leak is likely. Repair the leak
and repeat the evacuation process.

Step 4.4 Adding refrigerant (if needed)
The outdoor unit is charged with sufficient R-410A refrigerant
to support up to a 5 m line set. For lengths greater than 5 m,
you must add 15g of refrigerant per meter of additional
length, after the lines are evacuated.
1
Calculate the additional refrigerant required:
Additional grams of R-410A = (Total line set meter − 5)
× 15
2
Connect the common hose of the manifold gauge set to
the inverted R-410A refrigerant cylinder.
3
Place the refrigerant cylinder on a scale set to measure
grams.
4
Open the valve on the tank.
5
At the manifold connection, bleed the refrigerant to
remove any air that may be present in the common hose.
6
Open the gauge manifold and charge the system with the
amount of refrigerant calculated in step 1.
7
Close the gauge manifold valve, close the valve on the
refrigerant tank, and remove the common hose.
Step 4.5 Preparing the system for
commissioning
1
Wrap the remaining refrigerant pipe lengths and
connection points with foam insulation.
2
Wrap the unwrapped portions of the piping bundle with
vinyl tape.
3
With the manifold gauge set still installed, open the
isolation valves on the outdoor unit to connect the
outdoor unit to the line set and indoor unit.
4
Remove the manifold set and vacuum gage.
Step 4.6 Commissioning the unit
