SAFETY INSTRUCTIONS
High voltage electricity is required to operate this system.
Adhere to the National Electrical Codes and these
instructions when wiring.
Improper connections and inadequate grounding can cause accidental
injury or death.
Always ground the unit following local, state, and National
Electrical Codes.
There is risk of fire, electric shock, physical injury or death.
Turn the power off at the nearest disconnect before servicing
the equipment.
Electrical shock can cause physical injury or death.
Properly size all circuit breakers or fuses.
There is risk of fire, electric shock, explosion, physical injury or death.
WIRING
The information contained in this manual is intended for use
by an industry-trained, experienced electrician familiar with
the U.S. National Electric Code (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 electric work must be performed by a licensed electrician
and conform to local building codes or, in the absence of
local codes, with the National Electrical Code, and the
instructions given in this manual.
If the power source capacity is inadequate or the electric work is not
performed properly, it may 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 may generate heat and cause a fire.
Secure all field wiring connections with appropriate wire
strain relief.
Improperly securing wires will create undue stress on equipment power
lugs. Inadequate connections may generate heat, cause a fire and result
in physical injury or death.
Properly tighten all power lugs.
Loose wiring may overheat at connection points, causing a fire, physical
injury or death.
Do not change the settings of the protection devices.
If the pressure switch, thermal switch, or other protection devices are
bypassed or forced to work 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 supply power to the unit until all electrical wiring,
controls wiring, piping, installation, and refrigerant system
evacuation are completed.
The information contained in this manual is intended for
use by an industry-trained, experienced, certified electrician
familiar with the U.S. National Electric Code (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 equipment malfunction or property damage.
OPERATION
Do not provide power to or operate the unit if it is flooded
or submerged.
There is risk of fire, electric shock, physical injury or death.
Use a dedicated power source for this product.
There is risk of fire, electric shock, physical injury or death.
Do not operate the disconnect switch with wet hands.
There is risk of fire, electric shock, physical injury or death.
Periodically verify the equipment mounts have not
deteriorated.
If the base collapses, the unit could fall and cause physical injury or death.
Use inert (nitrogen) gas when performing leak tests or air
purges.
Do not use compressed air, oxygen, or flammable
gases.
Using these substances may cause fire, explosion, and physical injury
or death.
If refrigerant leaks out, ventilate the area before operating the
unit.
If the unit is mounted in an enclosed, low-lying, or poorly ventilated area,
and the system develops a refrigerant leak, it may cause a fire,
electric shock, explosion, physical injury or death.
Do not allow water, dirt, or animals to enter the unit.
There is risk of fire, electric shock, physical injury or death.
Do not touch the refrigerant piping during or after operation.
It can cause burns or frostbite.
Do not operate the unit with the panel(s) or protective
cover(s) removed; keep fingers and clothing away from
moving parts.
The rotating, hot, cold, and high-voltage parts of the unit can cause
physical injury or death.
