SAFETY PRECAUTIONS
WIRING
DANGER
High voltage electricity is required to operate chiller. Adhere
to the U.S. National Electric Codes (NEC) and these instruc-
tions when wiring.
Improper connections and inadequate grounding can cause accidental
injury or death.
Always ground the unit following local, state, and NEC codes.
There is risk of fire, electric shock, and physical injury or death.
Turn the power off before servicing the chiller. Ensure the
power is completely off and out of all components.
Electrical shock can cause physical injury or death.
Do not supply power to the unit until all electrical wiring,
controls wiring, and piping installation are completed.
There is risk of fire, electric shock, and physical injury or death.
Properly size all circuit breakers, fuses and power wiring.
WARNING
The information contained in this manual is intended for use
by an industry-qualified, experienced, trained electrician
familiar with the NEC who is equipped with the proper tools
and test instruments.
Failure to carefully read and follow all instructions in this manual can
result in personal injury or death.
All field wiring and component installation must be per-
formed by a licensed electrician and conform to local
building codes or, in the absence of local codes, with the
NEC, and the instructions and wiring diagrams given in this
manual.
If the power source capacity is inadequate or the electric work is not
performed properly, it will result in fire, electric shock, physical injury or
death.
Refer to local, state, and federal codes, and use power wires
of sufficient current capacity and rating.
Wires that are too small will generate heat and cause a fire, and physical
injury or death.
Do not supply power to the unit until all electrical wiring,
controls wiring, and piping installation are completed.
The system will malfunction.

There is risk of fire, electric shock, explosion, physical injury or death if
the electrical components are too small.
Do not share the electrical circuit with other devices. En-
sure the chiller(s) has/have dedicated circuit(s) and breaker(s).
There is risk of fire, electric shock, and physical injury or death due to
heat generation.
Do not use damaged or loose power wiring.
modify or extend the chiller's power wiring. Ensure that the
power wiring will not be pulled nor weight be placed on the
power wiring during operation.
There is risk of fire, electric shock, and physical injury or death.
Secure all field wiring connections with appropriate wire
strain relief.
Improperly securing wires will create undue stress on equipment power
connections. Inadequate connections will generate heat, cause a fire,
and physical injury or death.
Ensure the system is connected to a dedicated power source
that provides adequate power.
If the power source capacity is inadequate or the electric work is not
performed properly, it will result in fire, electric shock, physical injury or
death.
Properly tighten all power connections.
Loose wiring will overheat at connection points, causing a fire, physical
injury or death.
Do not change the settings of the protection devices.
If the protection devices have been bypassed or is 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.
