    • Fixing ODU stand if available
    • Checking the machine performance
    • Demo of the product
  • What is not covered in a standard installation scope, & will involve additional charges!!

    • Drilling more than one hole for copper pipe connectivity between IDU and ODU
    • Thicker concrete wall needs specialized equipment, so drilling holes through them will incur additional cost (core cutting). No wall chiseling / civil or mason work is included
    • An additional voltage stabilizer, if there are voltage fluctuations in the area
    • Wiring extension from Electricity Meter to Installation site, Power point/MCB fitting and any other Electrical work will be organized by the customer from their side.
    • Any extra copper pipe length that might be needed for installation (as per customer’s site requirement) beyond the copper pipe supplied with the product and the labour charges for laying this additional copper pipe cost will be borne by customer.
    • Grill/glass cutting and welding work will be organized by customer from their side.
    • Uninstallation/Shifting of old AC
    • Outdoor stand if supplied by customer, labour charges for fixing same has to be borne by customer.
    • Ladder to be arranged by customer in case required at installation site.
    • In case piping is already pre-laid by customer during construction stage, then nitrogen pressure testing will be required after connecting outdoor and indoor. The cost of the same to be borne by customer.
    • Anything else not covered in standard installation will be chargeable.

    The installation Engineer can arrange for additional material required, give you an invoice or receipt for it, and collect payment from you as per the invoice or receipt.

    The Engineer will be able to advise you if the additional work required can be handled by him or if you would need to arrange for it separately.

  • The air conditioner does not start operation immediately after it is turned on.

    To reduce excessive load in a restart, the air conditioner does not operate for three minutes when the ON switch is pressed immediately after it is shut down or when the operation mode (setting) is changed using the remote controller.

  • The air conditioner does not blow air immediately after it starts operation in the heating mode.

    The air conditioner conducts a "warm-up" operation first so that it won't blow cold air in the heating mode. The fan starts operating after one to four minutes of warm-up operation. (The warm-up operation becomes longer when the outside air temperature is low.)

  • The air conditioner produces a water flowing sound.

    The water flowing sound is produced by the refrigerant that flows inside the air conditioner. This sound is more prone to generation when the defrost operation is activated in a heating operation.

  • The air conditioner produces an air releasing sound.

    The air releasing sound is caused by a change of the refrigerant flow direction. This sound is generated when the air conditioner stops operating or the defrosting operation is activated in a heating operation.

  • The air condition produces a crackling sound.

    Plastic parts such as the front panel produces a crackling sound when they expand or contract slightly due to temperature change.

  • The outdoor unit discharges water or steam.

    The defrost operation activated in the heating mode removes frost, which turns into water or steam. A small amount of water is also discharged during a heating operation.

  • The amount of drained water is large (as compared to the amount discharged in the previous year or the day before).

    The amount of drained water varies depending on room temperature and humidity. A large amount of drained water does not denote a malfunction.

  • The air conditioner does not operate (Operation lamp is not lit).

    Check the following:

    • Make sure the circuit breaker is not turned off and the fuse is not blown.
    • Make sure the power cord plug is connected securely to the service outlet.
    • Make sure there is no power outage.
    • Make sure the remote controller has new batteries.
    • Make sure the timer is not programmed mistakenly.
  • The air conditioner does not cool or warm the room.

    Check the following.
    • Make sure the air filters are not dirty.
    • Make sure the air inlets and outlets of the indoor and outdoor units are not blocked by objects.
    • Make sure the temperature setting on the remote controller is appropriate.
    • Make sure the doors and windows are closed.
    • Make sure the air flow and direction settings are appropriate.
    • Make sure ventilation fans in the room are not operating.
  • The air conditioner stops operating (Operation lamp blinks).

    • Check to see if the air filters are clean.
    • Also make sure the air inlets and outlets of the indoor and outdoor units are not blocked.
  • The air conditioner operates abnormally.

    Lightning and radiowaves can sometimes cause abnormal operations of air conditioners.

    Cut off the power supply by unplugging the power cord or turning off the circuit breaker, then re-supply power and restart the air conditioner.

  • The indoor unit produces a mist.

    The cold air blow out during a cooling operation reduces the temperature of the room air and sometimes generates a mist.

  • The air conditioner stops operation (Operation lamp remains lit).

    When power supply voltage fluctuates largely, the air conditioner may stop operating to protect the equipment. (When power supply returns to a normal condition, the air conditioner resumes operation after three minutes.)

  • The air conditioner stops in the middle of operation (ON timer in operation).

    When the ON timer is set, the air conditioner may start as early as one hour before the set time in order to bring the room temperature close to the temperature set with the remote controller.

    If the remote controller is operated (except ON/OFF operation) during this time period, the air conditioner enters the stop mode.

    When this happens, turn on the air conditioner using the remote controller, and set the timer again.

  • The air conditioner produces an unpleasant odor.

    Room, furniture and cigarette smoke odors enter the indoor unit and remain in the unit. When the air conditioner is turned on, it blows the accumulated odors together with air. (It is recommended to clean the inside of the indoor unit. Call the contact center.)

    • The power cord and plug are extremely hot or damaged.
    • Abnormal noise is produced during operation.
    • Foreign items or water entered the air conditioner accidentally.
    • Circuit breaker, fuse or earth leakage circuit breaker trips frequently.
    • The ON switch or button sometimes fails to operate the air conditioner.
    • Burning odors are produced.
    • Water leaks from the indoor unit.
    • The Operation lamp blinks, and the temperature indicator displays two alphanumeric characters.
      (The display indicates the type of error. Check the alphanumeric characters and notify your dealer when requesting a repair.)
