Notices for use

The conditions of unit can’t normally run

  • Within the temperature range provided in following table, the air conditioner may stop running and other anomalies may arise.

Cooling Heating

Outdoor Indoor Outdoor Indoor

43(Apply to T1) 52(Apply to T3) 18 24 -7

  • When the temperature is too high, the air conditioner may activate the automatic
    protection device, so that the air conditioner could be shut down. When the temperature is too low, the heat exchanger of the air conditioner may
    freeze, leading to water leakage or other malfunction.
    In long-term cooling or dehumidification with a relative humidity of above 80%
    (doors and windows are open), there may be water condenses or dripping near
    the air outlet. * T1 and T3 refer to ISO 5151.

Notes for heating

  • The fan of the indoor unit will not start running immediately after the heating is started to avoid blowing out cool air.
  • When it is cold and wet outside, the outdoor unit will develop frost over the heat exchanger which will compromise the heating capacity. This is when the air conditioner will start defrost.
  • During defrost, the air conditioner will stop heating for about 5-12 minutes. Vapor may come out from the outdoor unit during defrost. This is not a malfunction,
    but a result of fast defrost.
    Heating will resume after defrost is complete.
    Notes for turning off
  • When the air conditioner is turned off, the main controller will automatically decide whether to stop immediately or after running for dozens of seconds with lower frequency and lower air speed.

Notices for use

Emergency operation

  • If the remote controller is lost or broken, use force switch button to operate the air conditioner.
  • If this button is pushed with the unit OFF, the air conditioner will operate in Auto mode.
  • If this button is pushed with the unit ON, the air conditioner will stop running.

Force switch

Airflow direction adjustment
1. Use up-down swing and left-right swing buttons on the remote controller to adjust the airflow direction. Refer to the operation manual of the remote controller for detail.
2. For models without left-right swing function, the fins has to be moved manually.
Note: Move the fins before the unit is in operation, or your finger might be injured. Never place your hand into the air inlet or outlet when the air conditioner is in operation.

ATTENTION
If the equipment emissions cannot meet the technical requirement of IEC 61000-3-3, following Attention should be take care. Attention:This appliance can be connected only to a supply with system impedance no more than Zmax. In case necessary, please consult your supply authority for system impedance information.

Clean and care
Warning
Before the cleaning of the air conditioner, it must be shut down and the electricity must be cut off for more than 5 minutes, otherwise there might be the risk of electric shocks.
Do not wet the air conditioner, which can cause an electric shock. Make sure not to rinse the air conditioner with water under any circumstances.
Volatile liquids such as thinner or gasoline will damage the air conditioner housing, therefore please clean the housing of air conditioner only with soft dry cloth and damp cloth moistened with neutral detergent.
In the course of the using, pay attention to cleaning the filter regularly, to prevent the covering of dust which may affect the effect. If the service environment of the air conditioner is dusty, correspondingly increase the number of times of cleaning. After removing the filter, do not touch the fin part of the indoor unit with the finger, so as to avoid scratching it.

Clean the panel
When the panel of the indoor unit is contaminated, clean it gently with a wrung towel using tepid water below 45, and do not remove the panel while cleaning.

Remove the air filter

Clean the air filter

1. Use both hands to open the panel for an angle from both ends of the panel in accordance with the direction of the arrow.
2. Release the air filter from the slot and remove it.
Clean the Air Filter Use a vacuum cleaner or water to rinse filter, and if the filter is very dirty (for example, with greasy dirt), clean it with warm water (below 45) with mild detergent dissolved in, and then put the filter in the shade to dry in the air.
– 9 –

Clean and care
Clean the air filter
Mount the Filter 1. Reinstall the dried filter in reverse order of removal, then cover and lock the panel.
Check before use
1. Check whether all the air inlets and outlets of the units are unblocked. 2. Check whether there is blocking in the water outlet of the drain pipe, and
immediately clean it up if any. 3. Check the ground wire is reliably grounded. 4. Check whether the remote control batteries are installed, and whether the power
is sufficient. 5. Check whether there is damage in the mounting bracket of the outdoor unit, and
if any, please contact our local service center.
Maintain after use
1. Cut off the power source of the air conditioner, turn off the circuit breaker and remove the batteries from the remote control.
2. Clean the filter and the unit body. 3. Remove the dust and debris from the outdoor unit. 4. Check whether there is damage in the mounting bracket of the outdoor unit, and if
any, please contact our local service center.
Troubleshooting
Caution

  • Do not repair the air conditioner by yourself as wrong maintenance may cause electric shock or fire, please contact the authorized service center and let the professionals conduct the maintenance, and checking the following items prior to contacting for maintenance can save your time and money.

Troubleshooting

Phenomenon

Troubleshooting

Air conditioner can not operate at all.
Remote controller is not available.
Cooling (Heating) efficiency is not good.

Has the power been shut down?

Is the wiring loose?

Is voltage too high or too low ?(measured by professionals)

Does it reach the set time for start up?

Does the circuit protection device trip?

Is the remote controller out of effective distance to the indoor unit?

Are there any obstructions between the controller and the

signal receptor?

Is the battery exhausted?

Is the setting temperature suitable? Are air filter dirty? Is the air inlet or outlet obstructed? Is indoor fan speed set at low speed? Is there any heat source in your room?

Indoor unit does not operate immediately when the air conditioner is restarted.

If the air conditioner is turned on immediately after it is turned off, the protective delay switch will delay the operation for 3 to 5 minutes.

There is unusual smell blowing from the outlet after operation is started.

The air conditioner itself does not have undesirable odor. If there is odor, it may be due to accumulation of the odor in the environment. Please clean the air filter or activate the cleaning function.

There is sound of running water during the running of air conditioner.

Sometimes the “hissing” sound of running water can be heard. This is the sound of the flow of the refrigerant, not a malfunction.

A slight “click” sound is heard at the of start-up or shut-down.

Due to temperature changes, panel and other parts will swell, causing the sound of friction. This is normal, not a fault.

During the cooling operation, the indoor unit outlet sometimes will blow out mist.

This is because the indoor air is cooled rapidly. After it runs for some time, the indoor temperature and humidity will be reduced and the mist will disappear.

Immediately stop all operations and cut off the power supply , contact our Service center locally in following situations.
Shrill sound is heard or Unpleasant odor is emitted during the operation. There is an abnormal heat in power supply cord and power plug. Accidentally pour impurities or water into the machine or the remote control. Air switch or protection switch often breaks.
