CAUTION
!
• Be very careful when transporting the product. There is a risk of
the product falling and causing physical injury.
- Use appropriate moving equipment to transport each frame;
ensure the equipment is capable of supporting the weight of
the equipment.
• The Limited Warranty is void and of no effect, and LG will have
no liability hereunder to any Customer or third party, to the
extent any of the following occur: acts, omissions, and conduct
of any and all third parties including, but not limited to, the
installing contractor and any repairs, service or maintenance by
unauthorized or unqualified persons.
• Do not insert a drain hose in drain pipe or sewer pipe.
- Bad smells can occur and it results in a corrosion of a heat
exchanger or pipe.
• Do not install the unit in potentially explosive atmospheres.
• The installation of pipe-work shall be kept to a minimum
• Any person who is involved with working on or breaking into a
refrigerant circuit should hold a current valid certificate from an
industry-accredited assessment authority, which authorises their
competence to handle refrigerants safely in accordance with an
industry recognised assessment specification.
• When mechanical connectors are reused indoors, sealing parts
shall be renewed.
• When flared joints are reused indoors, the flare part shall be re-
fabricated.
WARNING
!
• An authorized, trained technician licensed locally and at the state
level must install the unit.
- Improper installation by the user may result in fire, explosion,
electric shock, physical injury or death.
• Wear protective gloves when handling equipment. Sharp edges
may cause personal injury.
• Always check for system refrigerant leaks after the unit has been
installed or serviced.
- Exposure to high concentration levels of refrigerant gas may
lead to illness or death.
• Dispose the 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.
• Install the unit considering the potential for strong winds or
earthquakes.
- Improper installation may cause the unit to fall over, resulting in
physical injury or death.
• Install the unit in a safe location where nobody can step on or fall
onto it. T Do not install the unit on a defective stand.
- It may result in an accident that causes physical injury or death.
• Properly insulate all cold surfaces to prevent "sweating."
- Cold surfaces such as uninsulated piping can generate
condensate that could drip, causing a slippery surface that
creates a risk of slipping, falling, and personal injury.
• Do not store or use flammable gas or combustibles near the unit.
- There is risk of fire, explosion, and physical injury or death.
Safety Instructions - Installation
(For add on heat pumps with flammable refrigerants)
1) Instruction for installation of the critical-to-safety wiring
connection of the leak detection sensor or leak detection
system to the furnace assembly.
- The wiring shall be not less than 18 AWG with a minimum
insulation thickness of 1.58 mm or protected from damage.
Critical-to-safety wiring is any field installed wiring necessary to
fulfill the requirements of flammable refrigerant in the event of
detection of a leak.
2) Shall not be installed on furnaces with an inductive electrical
greater than Le
- Le = 5 when breaking alll phases of a three phase load
- Le = 2.5 all others
3) Detection of a leak shall turn on the indoor fan at the highest
available speed or turn it on to not less minimum air flow rate
(Consult furnace manufacturer.)
• Do not use means to accelerate the defrosting process or to
clean, other than those recommended by the manufacturer.
• The appliance shall be stored in a room without continuously
operating ignition sources (for example: open flames, an
operating gas appliance or an operating electric heater.)
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
• The manufacturer may provide other suitable examples or may
provide additional information about the refrigerant odour.
• Pipe-work including piping material, pipe routing, and installation
shall include protection from physical damage in operation and
service, and be in compliance with national and local codes and
standards, such as ASHRAE 15, ASHRAE 15.2, IAPMO Uniform
Mechanical Code, ICC International Mechanical Code, or CSA
B52.All field joints shall be accessible for inspection prior to being
covered or enclosed.
• An unventilated area where the appliance using flammable
refrigerants is installed shall be so constructed that should any
refrigerant leak, it will not stagnate so as to create a fire or
explosion hazard.
• Field-made refrigerant joints indoors shall be tightness tested.
The test method shall have a sensitivity of 5 grams per year of
refrigerant or better under a pressure of at least 0,25 times the
maximum allowable pressure. No leak shall be detected;
• If appliances connected via an air duct system to one or more
rooms with A2L REFRIGERANTS are installed in a room with an
area less than Amin as determined in standard, that room shall
be without continuously operating open flames (e.g. an operating
gas appliance) or other POTENTIAL IGNITION SOURCES (for
e.g., an operating electric heater, hot surfaces). A flame-
producing device may be installed in the same space if the
device is provided with an effective flame arrest.
