Safety Information
General information
࡛The air conditioner should be used only for the applications for which it has been designed: the indoor unit is not
suitable to be installed in areas used for laundry.
Installation of the product
࡛Our units must be installed in compliance with the spaces indicated in the installation manual to ensure either
accessibility from both sides or ability to perform routine maintenance and repairs. The units’ components must be
accessible and that can be disassembled in conditions of complete safety either for people or things. For this reason,
where it is not observed as indicated into the Installation Manual, the cost necessary to reach and repair the unit (in
safety, as required by current regulations in force) with slings, trucks, scaffolding or any other means of elevation won’t
be considered in-warranty and will be charged to end user.
Power supply line, fuse, or circuit breaker
࡛Be sure not to perform power cable modification, extension wiring, and multiple wire connection.
ࣞIt may cause electric shock or fire due to poor connection, poor insulation, or current limit override.
ࣞWhen extension wiring is required due to power line damage, refer to "Step 2-5 Optional: Extending the power cable"
in the installation manual.

Make a U-trap (A) on the pipe (which is connected to
the indoor unit) at outerwall and cut the bottom part of
the insulation (about 10 mm) to prevent rainwaterfrom
getting inside through the insulation.

Installation
Step 1-3 Choosing the installation
location
If using a multi system, install as described in the
installation manual supplied with the outdoor unit.
WARNING
࡛Verify that a dedicated circuit breaker and a disconnect
switch of the appropriate sizes for the air conditioner
are preinstalled and available for use. See the submittal
document for the model, listed on page 3.
࡛Verify that the voltage and frequency of the power
supply comply with the rated voltage as defined on the
unit name plate.
࡛Verify that a suitable grounding connection is available.
࡛Do not install this appliance in an environment
containing hazardous substances or close to equipment
that releases open flames.
࡛Do not install this appliance near a heater or flammable
material.
CAUTION
࡛The manufacturer shall not be responsible for damage
occurring as a result of the wrong voltage being
applied to this air conditioner.
࡛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.
IMPORTANT
࡛Any changes or modifications to the installation
described in this manual that are not expressly
approved by the manufacturer could void the
manufacturer’s warranty.
To determine where to locate the indoor and outdoor units,
you must survey the entire site and consider many variables.
The goal is to select locations that complywith all safety
precautions while also minimizing the total effort involved.
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 customerwants 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
࡛This manual covers a typical gravity-drain installation
where the drain hose is routed to the outdoor unit
through a hole in the wall.

Outdoorunit location requirements
Examine the area where the outdoor unit could be located.
Consider the following:
࡛What location will meet minimum clearances and
provide optimal product performance?
࡛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.
࡛Does the unit need to be mounted on the wall?
࡛Where are the dedicated circuit breaker and disconnect
switch located? How will you connect them to the unit?
࡛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?
࡛Will the unit be sheltered from the wind? In a
high-wind area, you may need to build a protective
fence around the unit.
࡛Where will the condensate drain?
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.
CAUTION
࡛Do not connect the drain hose to existing waste pipes
as odors may arise.
Installation on an exteriorwall
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.
Installation Guide at the seashore
Make sure to follow below guides when installing at the
seashore.
1 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.
2 Consider that the salinity particles clinging to the external
panels should be sufficientlywashed 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.
ࣞKeep the floor level so that rain does not accumulate.
ࣞBe careful not to block the drain hole due to foreign
substance.
4 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.
ࣞCheck the installation site every 3 months and
perform anti-corrosion treatment such as R-Pro
supplied by SAMSUNG (Code : MOK-220SA) or
commercial water repellent grease and wax, etc.,
based on the product condition.
ࣞWhen the product is to be shut down for a long
period of time, such as off-peak hours, take
appropriate measures like covering the product.
8 If the product installed within 1640.4 ft (500 m) of
seashore, special anti-corrosion treatment is required.
