SAFETY INSTRUCTIONS
Do not install the MultiSITE Controller unit if it will be exposed to rain or
other precipitation.
Do not install the unit in a location exposed to open
ame or extreme heat.
Do not touch the unit with wet hands.
There is risk of re, electric shock, physical injury and/or death.
Replace all control box and panel covers.
If cover panels are not installed securely, dust, water and animals may enter the unit,
causing re, electric shock, and physical injury or death.
Wear protective gloves when handling equipment.
Sharp edges may cause personal injury.
Dispose of any 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 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 specied by LG are used, there is risk of
re, electric shock, explosion, and 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.
Note:
MultiSITE Controller is for use with select LG commercial air conditioning
systems only.
Do not attempt to use MultiSITE Controller with any other
type of system. Refer to the compatible equipment list in this manual.
There is risk of equipment damage or degraded performance
Do not cut, lengthen or shorten the cable between the MultiSITE Control-

CONTROLLER INSTALLATION
Selecting Installation Location
The room temperature sensor is inside the controller, so the installation
location is critical to proper system operation. Install the controller in a
location away from direct sunlight, high humidity, and direct flow of hot or
cold air. Install the controller on a flat, clean wall surface approximately 5 ft
above the floor in an area with good circulation and average temperature.
Do not install the controller where it is exposed to:
• Drafts or dead spots behind doors and in corners
• Hot or cold air from ducts
• Radiant heat from sun or appliances
• Concealed pipes or chimneys
• Uncontrolled areas such as on an outside wall
Refer to Figure 1 for a typical installation location.
