SAFETY INSTRUCTIONS
INSTALLATION - CONTINUED
Periodically check that the outdoor frame is not damaged.
There is a risk of equipment damage, explosion, physical injury, or death.
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, explosion,
and physical injury or death.
Be very careful when transporting the product.
• Do not attempt to carry the product without assistance in order to
avoid physical injury.
• Some products use polypropylene bands for packaging. Do not use
polypropylene bands to lift the unit. Lifting the unit might cause phys-
ical injury.
• Suspend the unit from the base at specified positions to avoid prop-
erty damage or physical injury .
Don't install the unit where it's directly exposed to ocean winds.
Ocean winds may cause corrosion, particularly on the condenser and
evaporator fins, which, in turn could cause product malfunction or inef-
ficient performance.
When installing the unit in a low-lying area, or a location that
is not level, use a raised concrete pad or concrete blocks to
provide a solid, level foundation.
This may prevent water damage and reduce abnormal vibration.
Properly insulate all cold surfaces to prevent "sweating."
Cold surfaces such as uninsulated piping can generate condensate that
may drip and cause a slippery floor condition and/or 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.

Replace all control box and panel covers.
If cover panels are not installed securely, dust, water and animals may
enter the water source unit, causing fire or equipment malfunction.
Always check for system refrigerant leaks after the unit has
been installed or serviced.
Low refrigerant levels may cause product failure, and exposure to high
concentration levels of refrigerant gas may lead to illness or death. Keep
the unit upright during installation to avoid vibration or water leakage.
• Support the unit a minimum of four points to avoid slippage from
rigging apparatus which may result in physical injury.
Install the drain hose to ensure adequate drainage.
There is a risk of water leakage and property damage.
Do not use the product for special purposes such as
preserving foods, works of art, wine coolers, or other
precision air conditioning applications. The 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 tubing, remember to allow for
pipe expansion.
Improper piping may cause refrigerant leaks and system malfunction.
Do not install the unit in a noise sensitive area.
Take appropriate actions at the end of HVAC equipment life
to recover, recycle, reclaim or destroy R410A refrigerant
according to applicable U.S. Environmental Protection
Agency (EPA) rules.
