Do not install, remove, or re-install the unit by yourself
(customer). Ask the dealer or an authorized technician to
install the unit.
Improper installation by the user may result in water leakage, fire,
explosion, electric shock, physical injury or death.
For replacement of an installed unit, always contact an
authorized LG service provider.
There is risk of fire, electric shock, explosion, and physical injury or death.
Do not install the water-source units outside.
There is risk of fire, electric shock, explosion, and physical injury or death.
Be very careful when transporting the product.
• One person should not carry the product.
• Some products use polypropylene bands for packaging. Do not use
polypropylene bands to lift the unit.
• Suspend the water source unit from the base at specified positions.
Support the water source unit a minimum of four points to avoid slip-
page from rigging apparatus.
The water source unit is shipped with refrigerant and the ser-
vice valves closed. Do not open service valves on the water
source unit until all non-condensable have been removed
from the piping system and authorization to do so has been
obtained from the commissioning agent.
There is a risk of equipment damage, refrigerant contamination, refriger-
ant loss, physical injury or death.
The water source unit is shipped with a refrigerant and
service valves closed. Do not run the compressor with the
service valves closed.
There is a risk of equipment damage, explosion, physical injury, or death.
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.
Install the unit considering the potential for strong winds or
earthquakes.
Improper installation may cause the unit to fall over, resulting in physical
injury or death.
If the air conditioner is installed in a small space, take
measures to prevent the refrigerant concentration from
exceeding 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
refrigerant leaks and safety limits are exceeded, it could result in personal
injuries or death from oxygen depletion.
Wear protective gloves when handling equipment. Sharp
edges may cause personal injury.
Do not install the unit on a defective stand.
It may result in an accident that causes product damage or personal 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.
Do not store or use flammable gas or combustibles near the
unit.
There is risk of product failure, fire, explosion, and physical injury or death.
