SAFETY PRECAUTIONS
TABLE OF SYMBOLS
DANGER
This symbol indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
This symbol indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION
This symbol indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.
This symbol indicates situations that may result in equipment or property damage accidents only.
This symbol indicates an action that should not be performed.
The instructions below must be followed to prevent product malfunction, property damage, injury or death to the user or other people. Incor-
rect operation due to ignoring any instructions will cause harm or damage. The level of seriousness is classified by the symbols described
below.
Safety of personnel is the primary concern during all procedures. Read and understand this safety summary. Read and understand the instal-
lation procedure before beginning installation. Use the appropriate tools and accessories during installation. Plan the work and do not
work alone, if possible. Know how to obtain emergency medical and fire fighting assistance.
DANGER
Do not use or store ammable gas or combustibles near
the unit.
There is risk of re, explosion, and physical injury or death.
Disconnect power before installing or servicing the unit.
There is risk of physical injury or death due to electric shock.
Properly size all circuit breakers or fuses.
There is risk of re, electric shock, explosion, physical injury, or death.
Do not share the electrical circuit with other devices.
There is risk of re, electric shock, physical injury, or death due to heat
generation.
Do not use damaged or loose power wiring. Do not
modify or extend the power wiring randomly. Ensure that the
power wiring will not be pulled nor weight be placed on the
power wiring during operation.
There is risk of re, electric shock, and physical injury or death.
The information contained in this manual is intended for use
by an industry-qualied, experienced, trained electrician
familiar with local, national, and regional codes and who is
equipped with the proper tools and test instruments.
Failure to carefully read and follow all instructions will result in personal
injury or death.
All electric work must be performed by a licensed electrician
and conform to local building codes or, in the absence of lo-
cal codes, with the National Electrical Code, and the instruc-
tions given in this manual.
If the power source capacity is inadequate or the electric work is not
performed properly, it will result in re, electric shock, physical injury or
death.
Use copper conductors only. Refer to local, state, and federal
codes, and use power wires of su󰀩cient current capacity and
rating.
Wires that are too small will generate heat, cause a re and physical
injury or death.
Before making power terminations during earth grounding,
de-energize the power source. Do not restore power until
completing all other mounting and wiring.
There is risk of electric shock and physical injury or death.

SAFETY PRECAUTIONS
Discharge yourself correctly before handling and installing
the controller.
There is risk of electric shock and physical injury or death.
Install in a controlled environment relatively free of contami-
nants.
There is risk of electric shock and physical injury or death.
Secure all eld wiring connections with appropriate wire
strain relief.
Improperly securing wires will create undue stress on equipment power
lugs. Inadequate connections will generate heat, cause a re and physi-
cal injury or death.
Ensure the system is connected to a power source that pro-
vides adequate power. Ensure that the wiring is the correct
size.
If the power source capacity is inadequate, the wiring is not the correct
size, or the electric work is not performed properly, it will result in short
circuiting, re, electric shock, physical injury or death.
Do not change the settings of the protection devices.
If the protection device is shorted and forced to operate improperly, or
parts other than those specied by LG are used, there is risk of re,
electric shock, explosion, and physical injury or death.
Properly tighten all power connections.
Loose wiring may overheat at connection points, causing a re, physical
injury or death.
Dispose of any packing materials safely.
• Packing materials, such as nails and other metal or wooden parts
will 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 controller if it will be exposed to rain
or other precipitation. Do not install the unit in a location
exposed to open ame, extreme heat, or direct sunlight.
Do not touch the unit with wet hands.
There is risk of re, electric shock, physical injury, and/or death.
Use a soft, pre-moistened lint-free cloth for cleaning.
Avoid getting moisture in openings.
If moisture accesses the electrical components of the controller, there is
risk of re, electric shock, and physical injury or death.
Do not use caustic / corrosive products, ammonia, sol-
vents or any cleaning product containing alcohol or grit.
There is risk of re, electric shock, and physical injury or death.
Do not drop or crush the controller, or allow it to come
into contact with liquids.
There is risk of re, electric shock, and physical injury or death.
Do not spray anything directly on the controller or use
compressed air.
There is risk of re, electric shock, and physical injury or death.
Never use paint on the controller.
If moisture accesses the electrical components of the controller, there is
risk of re, electric shock, and physical injury or death.
Do not use a damaged device (such as one with a cracked
screen).
There is risk of re, electric shock, and physical injury or death.
Wear protective gloves when handling equipment.
Sharp edges cause personal injury.

A 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 or hot or cold air. Install the controller on a flat, clean wall surface approxi-
mately four to five (4 to 5) feet above the floor in an area with good circulation and average temperature.
Do's
• If replacing an existing controller, label wires before removing.
• Ensure the wall surface is flat and clean.
• Ensure the controller has sufficient, natural air circulation.
• Ensure the external thermal sensor wiring is away from electrical
sources.
• Install the controller four to five (4 to 5) feet (1.2 to 1.5m) above the
floor.
Do Not's
Do not install the controller:
• In drafts or dead spots behind doors and corners.
• In areas subjected to hot or cold air from ducts / air discharge grills
• Near radiant heat from sun or appliances
• Near or with a direct heat source.
• In areas exposed to direct sunlight.
• Near concealed pipes or chimneys.
• Uncontrolled areas such as on an outside wall.
Failure to comply with these recommendations will result in damage to the unit and void the manufacturer’s warranty.
