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.
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 re, electric shock, explosion, physical injury or death.
WIRING
The information contained in this manual is intended for use
by an industry-qualied, experienced, certied 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, property damage, 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 per-
formed properly, it may result in re, electric shock, physical injury or death.
Refer to local, state, and federal codes, and use power wires
of sufcient current capacity and rating.
Wires that are too small may generate heat and cause a re.
Secure all eld 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 re and phys-
ical injury or death.
Properly tighten all power lugs.
Loose wiring may overheat at connection points, causing a re, 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
specied by LG are used, there is risk of re, electric shock, explosion,
and physical injury or death.
Do not supply power to the unit until all installation and pre-
commissioning tasks are complete and the commissioning
agent indicates it is safe to do so.
OPERATION
Do not provide power to or operate the unit if it is ooded or
submerged.
There is risk of re, electric shock, physical injury or death.
Use a dedicated power source for this product.
There is risk of re, electric shock, physical injury or death.
Do not operate the disconnect switch with wet hands.
There is risk of re, electric shock, physical injury or death.
Periodically verify the equipment mounts have not
deteriorated.
If the base collapses, the unit could fall and cause property damage,
product failure, physical injury or death.
If gas leaks out, ventilate the area before operating the unit.
Leaking gas may cause re, electric shock, explosion, physical injury or
death if the unit is mounted in an enclosed, low-lying, or poorly ventilated
area and the system develops a refrigerant leak.
Do not allow water, dirt, or animals to enter the unit.
• There is risk of unit failure or fire.
• Handling of the unit while wet can cause electric shock, physical
injury or death.
• Animals entering the unit can cause unit failure or fire.
• Use caution when trying to remove any animals from the unit to avoid
personal physical injury.
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 ngers and clothing away from
moving parts.
The rotating, hot, cold, and high-voltage parts of the unit can cause
physical injury or death.
Periodically, check power cord and plug for damage.
Cord must be replaced by the manufacturer, its service agent, or similar
qualied persons in order to avoid physical injury and/or electric shock.
