INSTALLATION,
WARNING
Dispose the packing materials safely.
• Packing materials, such as nails and other metal or wooden parts
may cause puncture wounds or other injuries.
• Tear apart and throw away plastic packaging bags so that children
may not play with them and risk suffocation and death.
Do not install the unit in any location exposed to open flame
or extreme heat. Do not touch the unit with wet hands.
There is risk of fire, electric shock, explosion, and physical injury or death.
Install the unit considering the potential for earthquakes.
Improper installation may cause the unit to fall, resulting in physical
injury or death.
CAUTION
Be very careful when transporting the product.
• Do not attempt to carry the product without assistance.
• Some products use polypropylene bands for packaging. Do not use
polypropylene bands to lift the unit.
Note:
LG Electronics U.S.A.,Inc., is not responsible for any piping
calculations, refrigerant leaks, degradation of performance,
or any other potential problems or damages as a result of
interconnecting piping, their joint connections, isolation
valves, introduced debris inside the piping system, or other
problems caused by the interconnecting piping system.
Properly insulate all cold surfaces to prevent "sweating."
Cold surfaces such as uninsulated pipes can generate condensate
that may drip and cause a slippery floor condition and/or water dam-
age to walls.
When installing the unit in a hospital, mechanical room, or
similar electromagnetic field (EMF) sensitive environment,
provide sufficient protection against electrical noise.
Inverter equipment, power generators, high-frequency medical equip-
ment, or radio communication equipment may cause the air conditioner
to operate improperly. The unit may also affect such equipment by creat-
ing electrical noise that disturbs medical treatment or image broadcasting.
Do not use the product for special purposes such as preserv-
ing foods, works of art, wine coolers, or other precision air
conditioning applications. This equipment is designed to
provide comfort cooling and heating.
There is risk of property damage.
Do not make refrigerant substitutions. Use R410A only.
If a different refrigerant is used, or air mixes with original refrigerant,
the unit will malfunction and be damaged.
When connecting refrigerant pipe, allow for pipe expansion.
Improper piping may cause refrigerant leaks and system malfunction.
Periodically check that the water source unit is not damaged.
There is a risk of equipment damage.

SAFETY PRECAUTIONS
Do not change the settings of the protection devices.
If the pressure switch, thermal switch, or other protection device is
shorted and forced to operate improperly, or parts other than those
specified by LG are used, there is risk of fire, electric shock, explo-
sion, and physical injury or death.
If the air conditioner is installed in a small space, take mea-
sures to prevent the refrigerant concentration from exceed-
ing safety limits in the event of a refrigerant leak.
Consult the latest edition of ASHRAE (American Society of Heat-
ing, Refrigerating, and Air Conditioning Engineers) Standard 15. If
the refrigerant leaks and safety limits are exceeded, it could result in
personal injuries or death from oxygen depletion
• Suspend the unit from the base at specified positions.
• Support the unit at a minimum of four points to avoid slippage from
rigging apparatus.
• Failure to follow these Cautions can result in minor or moderate
physical injury.
Take appropriate actions at the end of HVAC equipment life
to recover, recycle, reclaim or destroy R410A refrigerant ac-
cording to applicable U.S. Environmental Protection Agency
(EPA) rules.
Install the water source unit in a safe location where no one
can step on or fall onto it. Do not install the unit with defec-
tive attaching or mounting hardware.
There is risk of unit and property damage.
Install the drain hose to ensure adequate drainage.
There is a risk of water leakage and property damage.
Don't store or use flammable gas combustibles near the unit.
There is risk of product failure.
Always check for system refrigerant leaks after the unit has
been installed or serviced.
Low refrigerant levels may cause product failure
The unit is shipped with refrigerant and the service valves
closed. Do not open service valves on the unit until all non-
condensibles have been removed from the piping system
and authorization to do so has been obtained from the com-
missioning agent.
There is a risk of refrigerant contamination, refrigerant loss and
equipment damage.
When installing the water source unit in a low-lying area, or
a location that is not level, use a raised concrete pad or con-
crete blocks to provide a solid, level foundation.
A solid, level foundation may prevent water damage and reduce
abnormal vibration.
Do not install the unit in a noise sensitive area.
