Installation, continued
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 Heating,
Refrigerating, and Air Conditioning Engineers) Standard 15. If the re-
frigerant leaks and safety limits are exceeded, it could result in personal
injuries or death from oxygen depletion.
CAUTION
Be very careful when transporting the product.
•
Do not attempt to carry the product without assistance.
• Some products use polypropylene bands for packaging.
• 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 directions may result in minor or moderate physical injury.
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 pipe can generate condensate that
may drip and cause water damage 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 creating
electrical noise that disturbs medical treatment or image broadcasting.
Do not use the product for special purposes such as
preserving foods, works of art, wine coolers, or other preci-
sion air conditioning applications. This equipment is de-
signed 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.
Do not install the unit in a noise sensitive area.
When connecting refrigerant tubing, remember to allow for
pipe expansion.
Improper piping may cause refrigerant leaks and system malfunction.
Do not use polypropylene bands to lift the unit.
Due to our policy of continuous product innovation, some specifications may change without notification.

SAFETY INSTRUCTIONS
Properly insulate all cold surfaces to prevent "sweating."
Cold surfaces such as uninsulated piping can generate condensate that
could drip, causing a slippery surface that creates a risk of slipping, fall-
ing, and personal injury.
Periodically check that the unit is not damaged.
There is a risk of equipment damage.
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 unit in a safe location where no one can step on or
fall onto it.
Do not install the unit with defective hanging,
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 commissioning agent.
There is a risk of refrigerant contamination, refrigerant loss and equip-
ment damage.
