LG C1008FA5 8.0 Ton Floor Standing Air Conditioner

TIPS FOR SAVING ENERGY
Here are some tips that will help you minimize the power consumption when you use the air conditioner. You can use your air conditioner more efficiently by referring to the instructions below:

  • Do not cool excessively indoors. This may be harmful for your health and may consume more electricity.
  • Block sunlight with blinds or curtains while you are operating the air conditioner.
  • Keep doors and windows closed tightly while you are operating the air conditioner.
  • Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
  • Speed up the fan to cool or warm indoor air quickly, in a short period of time.
  • Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or weaken the cooling / dehumidifying functions.

  • A place where noise prevention is taken into consideration.
  • Do not install the unit near the door way.
  • Ensure the spaces indicated by arrows from the wall, ceiling, or other obstacles.
  • The indoor unit must keep the maintenance space.

CAUTION

  • It’s not possible to apply the duct indoor unit to this model.
  • Do not disassemble, repair, or modify the product to install the duct. (This may cause performance degradation and burnout.)

WIRING CONNECTION

Connecting the cable
The inside and outside connecting cable can be connected after opening the inlet grille.

  1. Open the inlet grille manually.
  2. Open the control cover with screwdriver(⊕).
  3. Secure the control cover to the original position with the screw.
  4. Close the inlet grille.

Wiring Connection

  • Connect the wires to the terminals on the control board individually according to the outdoor unit connection.
  • Ensure that the color of the wires of outdoor unit and the terminal No. are the same as those of indoor unit respectively. <PF2>

  • Resistance measurement position for incorrect wiring.
  • Pipes and wires should be purchased separately for installation of the product.

WARNING
Use O-Ring or Y-Ring when connecting Power cable and Connecting cable.

CAUTION
The connecting cable connected to the indoor and outdoor unit should be complied with the following specifications (Rubber insulation, type H05RN-F approved by HAR or SAA).
(This equipment shall be provided with a cable set complying with the national regulation). NORMAL CROSS-SECTIONAL AREA 1.5 mm2 If the supply cord is damaged, it must be replaced by a special cord or assembly available from the manufacturer of its service agent. When the connection line between the indoor unit and outdooor unit and outdoor unit is over 40 m, connect the telecommunication line and power line separately.

CAUTION

  1. Never fail to have separate power specially for the air conditioner. As for the method of wiring, follow the circuit diagram pasted on the inside of control box cover.
  2. Provide a circuit breaker switch between power source and the unit.
  3. The screw which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit is subjected during the course of transportation. Check them and make sure that they are all tightly fastened. (If they are loose, it could give rise to burn-out of the wires.)
  4. Confirm the Specification of power source.
  5. Confirm that electrical capacity is sufficient.
  6. Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate.
  7. Confirm that the cable thickness is as specified in the power sources specification. (Particularly note the relation between cable length and thickness.)
  8. Do not install the leakage breaker in a place which is wet or moist. Water or moist may cause short circuit.
  9. The following troubles would be caused by voltage drop-down.
    1. Vibration of a magnetic switch, damage on the contact point there of, fuse breaking, disturbance to the normal function of a overload protection device.
    2. Proper starting power is not given to the compressor.
  10. Before applying power to the indoor unit, be sure to check for incorrect wiring of the power and communication lines.

CONNECTING PIPES

Preparation of Pipe
Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following procedure.

Cut the pipes and the cable.

  • Use the accessory pipe kit or the pipes purchased locally.
  • Measure the distance between the indoor and the outdoor unit.
  • Cut the pipes a longer than measured distance.
  • Cut the cable 1.5 m longer than the pipe length.

Burrs removal

  • Completely remove all burrs from the cut cross section of pipe.
  • Put the end of the copper pipe to downward direction as you remove burrs in order to avoid to let burrs drop in the pipe.

Putting nut on
Remove flare nuts attached to indoor and outdoor unit, then put them on pipe/tube having completed burr removal. (not possible to put them on after finishing flare work)

Flaring work

  1. Firmly hold copper pipe in a bar with the dimension shown in below table.
  2. Carry out flaring work with the flaring tool.
Pipe diameter

inch (mm)

 A inch (mm)
Wing nut type Clutch type
Ø 1/4 (Ø 6.35) 0.04~0.05 (1.1~1.3)  

0~0.02 (0~0.5)

Ø 3/8 (Ø 9.52) 0.06~0.07 (1.5~1.7)
Ø 1/2 (Ø 12.7) 0.06~0.07 (1.6~1.8)
Ø 5/8 (Ø 15.88) 0.06~0.07 (1.6~1.8)
Ø 3/4 (Ø19.05) 0.07~0.08 (1.9~2.1)

Check

  1. Compare the flared work with the figure by.
  2. If a flared section is defective, cut it off and do flaring work again

Welding

  • Pipe connections can be done on the front side or on the side according to the installation environments.
  • Be sure to let 1.0 kgf/cm2 Nitrogen flow in the pipe when we lding.
  • If Nitrogen was not flown during welding, many oxidized membranes may form inside the pipe and disturb the normal operations of valves and condensers.

Indoor unit installation

  1. The mounting floor should be strong and solid enough to prevent it from vibration.
  2. Drill the piping hole with 70 mm diameter  hole-core drill at either the right or the left of indoor unit. The hole should be sightly slant to the outdoor side.
  3. Insert the plastic tube through the hole.
  4. Cut the extruded outside part of the plastic tube, if necessary.

When using knock-out hole to route the piping, insert the plastic cover in knock-out hole in order to prevent the piping from damaged by sharp edge of the hole.

CAUTION

  • Install the product to remain horizontal using the horizontal gauge.
  • Do not damage cables when you install the indoor unit. There is risk of fire or electric shock.

Indoor Unit Drain Piping
Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following procedure.

  • Drain piping must have down-slope (1/50 to 1/100): be sure not to provide up-and-down slope to prevent reversal flow.
  • During drain piping connection, be careful not to exert extra force on the drain port on the indoor unit.
  • The outside diameter of the drain connection on the indoor unit is 32 mm.
  • Piping material: Polyvinyl chloride pipe inner diometes Ø 25 mm and pipe fittings.
  • Be sure to install heat insulation on the drain piping.
  • Heat insulation material: Polyethylene foam with thickness more than 8 mm.

Drain test
The air conditioner uses a drain pump to drain water. Use the following procedure to test the drain pump operation:

Airborne Noise Emission
The A-weighted sound pressure emitted by this product is below 70 dB. The noise level can vary depending on the site. The figures quoted are emission level and are not necessarily safe working levels. Whilst there is a correlation between the emission and exposure levels, this cannot be used reliably to determine whether or not further precautions are required. Factor that influence the actual level of exposure of the workforce include the characteristics of the work room and the other sources of noise, i.e. the number of equipment and other adjacent processes and the length of time for which an operator exposed to the noise. Also, the permissible exposure level can vary from country to country. This information, however, will enable the user of the equipment to make a better evaluation of the hazard and risk.

Limiting concentration
Limiting concentration is the limit of Freon gas concentration where immediate measures can be taken without hurting human body when refrigerant leaks in the air. The limiting concentration shall be described in the unit of kg/m3 (Freon gas weight per unit air volume) for facilitating calculation
