PART 2. OPERATING THE DEVICE

FUNKCJE SPECJALNE
Refrigerant leak detection function
With this new function, the detection of refrigerant leakage by the outdoor unit will be alerted by the appearance of the „EC” symbol on the display screen and the LEDs flashing.
Louver position memory function (optional)
This function allows you to remember the opening angle of the blind within the safe range. If the louver position is outside this range, the device will remember the safety angle limit value.
When the manual control button is pressed or the power cord plug is pulled out and reinserted into the mains socket, the blinds will revert to the standard setting.
We recommend not to set a low opening angle of the louvers as this may cause condensation and water dripping from the surface of the air conditioner.
Self cleaning function (optional)

• When the heating unit is turned off, the unit will automatically clean the evaporator and keep it clean until the next operation.

• Diagram of how the device works during self-cleaning: Fan mode (FAN), fan speed – low (LOW) – heating mode (HEAT), fan speed – low (cooling & heating units only) – fan mode – stop – off (OFF).
  REMEMBER:

• The self-cleaning function can only be activated when the appliance is in cooling (AUTO COOL or FORCED COOL) and DRY mode.

• It is recommended to run the unit in cooling mode for at least half an hour before activating the function.
  Running the self-cleaning function will cancel the timer settings.

• If you press the SELF CLEAN button while cleaning the appliance, the unit will turn off.
  Mold prevention function (optional)

• After turning off the unit working in COOL, DRY or AUTO (COOL) mode, the air conditioner will continue working for 7-10 minutes (depending on the model) at low fan speed. The unit working in HEAT mode after turning off will work for 30 seconds with low fan speed. Such behavior of the device will allow its interior to dry out of the condensate formed and prevent the growth of mold.

• Do not restart the unit while the anti-mold function is active and the air conditioner is not turned off completely.

OPERATING RANGE

REMEMBER

1. The device will achieve the highest efficiency in the above temperature ranges. If the air conditioner operates at temperatures outside the above mentioned range, some safety functions may be activated,  causing the device to operate unnaturally.
2. If the air conditioner is used for a long time in an environment with high humidity (exceeding 80%), water droplets may drip. In this situation, it is recommended to set the maximum opening angle of the  vertical blinds (vertically to the floor) and start the fan at high speed (HIGH).

MANUAL OPERATION OF THE DEVICE
The indoor units have a button to control the device during a remote control failure. You can get to it by opening the front panel. The button should only be used if a wireless remote control fails or needs service.

REMEMBER
Turn off the device before using the manual control button. If the unit is in operation, press the manual control button until it turns off.

1. Open and lift the front panel until you hear a click indicating that the panel is locked. For some models, use the bracket supporting the panel.
2. Pressing the button once will cause the unit to start in cooling mode. Pressing the button twice will start the heating mode, and pressing the button three times will turn off the unit.
3. Close the panel.

ATTENTION
The button should only be used in an emergency. To return to the remote control, simply start using it again.

ADJUSTING THE AIR FLOW DIRECTION

Incorrect adjustment of the air flow direction may cause uneven temperature distribution in the room and the related discomfort.
Use the wireless remote control to adjust the position of the horizontal blinds. Vertical blinds must be adjusted manually.
Adjusting the air outflow in the vertical plane (up and down)
Adjustments should be made while the indoor unit is on, using the wireless remote control. Each time the blind position button is pressed, the angle of inclination changes by 6°. Detailed information can be found in  the remote control manual
Adjusting the airflow in a horizontal plane (left – right)
Adjustments should be made while the indoor unit is on, using the wireless remote control.
IMPORTANT: Do not put your fingers in the place from which it flows out or into which air is sucked. A fan that rotates at high speed can be hazardous.

ATTENTION

• When the air conditioner is in cooling or dehumidifying operation for a long time, do not direct the air flow downwards. This can cause condensation on the surface of the blinds and water drops to fall on the  floor or furniture.
• If you turn on the device immediately after turning it off, the horizontal louvers may not move for about 10 seconds.
• The opening angle of the horizontal louvers should not be too small, as it may affect the efficiency of heating or cooling by limiting the air flow.
• Do not move the horizontal louvers by hand. This may cause them to desynchronize. If this happens, turn off the device, disconnect it from the power supply for a few seconds, and then restart it.
• Do not use the device when the horizontal louvers are in the closed position.

THE WAY THE AIR CONDITIONER WORKS

Operation in AUTO mode

• A device operating in automatic mode, based on the difference between the current room temperature and the set temperature, will decide whether it should heat, cool (only for cooling and heating units) or  ventilate.
• The air conditioner will control the room temperature and adapt it to the set temperature. If you feel uncomfortable when the device is in automatic mode, change the set temperature.

Working with the SLEEP function active
Pressing the SLEEP button during cooling, heating (cooling and heating models only) or the indoor unit’s automatic operation will lower (when heating) or increase (when cooling) the room temperature by 1°C/2°F  every hour for the first 2 hours, keep the temperature constant for another 5 hours, and then turn off the unit. This treatment allows you to save energy while maintaining comfortable conditions during the night.

Drying mode
During dehumidification, the fan speed will be controlled by the indoor unit.
If the room temperature during drying drops below 10°C(50°F), the compressor will shut down. The compressor will restart when the temperature exceeds 12°C (54°F).
Optimal performance
For the best performance of the device, follow these rules:

• Adjust the airflow direction so that it is not aimed directly at the people in the room.
• Adjust the temperature level to achieve thermal comfort. Do not set extreme temperature values.
• Close windows and doors when the air conditioner is in cooling or heating mode. This can reduce the efficiency of the device.
• Use the timer to program the time to turn on the air conditioner.
• Do not place any objects near the air inlet and outlet of the device. This can lead to a reduction in the efficiency of the air conditioner or even its shutdown.
• Clean the air filter periodically. The reduced air flow will reduce the performance of the device.
• Do not operate the air conditioner with the horizontal louvers closed.

PART 3. SERVICE OPERATIONS

ACTIVITIES BEFORE STARTING THE SERVICE

Before starting the service

• Turn off the air conditioning before cleaning. Wipe the device with a soft, dry cloth. Do not use bleaches or abrasives.

• Cleaning the front panel with water hotter than 40°C/104°F may result in its deformation or loss of its original color.

CLEANING THE DEVICE AND FILTERS

Cleaning the device
Wipe the device with a dry cloth. If the dirt is strong, moisten a cloth with warm water.
Cleaning the purifying filter and the air refreshing filter A dirty air filter can significantly reduce the efficiency of the device. It is recommended to clean the central heating filter every 2 weeks.

1. Open and lift the front panel until you hear a click, indicating that the panel is locked. For some models, it is necessary to use a support bracket for the panel.

2. Grasp the filter by the handles and gently lift it up. Take the filter out of the holder and pull it downwards.

3. Pull out the filter from the indoor unit.
   Clean the filter every 2 weeks, using a vacuum cleaner or water. Dry the damp filter in a cool place.

4. Remove the air freshener filter from the holding frame (certain models only).
   • Clean the air freshening filter at least once a month and replace it every 4-5 months.
   • Clean the filter with a vacuum cleaner and dry it in a cool place.

5. Put the air freshening filter back in its place.

6. Insert the purifying filter into the indoor unit, taking care to match its left and right edges.

FILTER REPLACEMENT

Replacing the purifying filter and the air refreshing filter

1. Take out the air purifying filter.
2. Remove the air freshening filter.
3. Install a new air freshening filter.
4. Place a new purifying filter in the device.

PREPARATION FOR A LONG PERIOD OF INACTIVITY AND PRE-SEASON CHECKS
Prepare for a long period of inactivity
If you plan not to use the device for a long period of time, take the following measures:

1. Clean the indoor unit and filters.
2. Run the fan for about half a day to dry the inside of the device.
3. Turn off the air conditioner and disconnect from the power supply.
4. Remove the batteries from the wireless remote control.
   The outdoor unit requires periodic inspection and cleaning. Do not do this yourself. Contact the seller or service.

Pre-season control

• Check that the cables are not damaged and that they are properly connected.
• Clean the indoor unit and filters.
• Check that the filters have been mounted.
• After a long period of non-use of the device, check whether the air inlet and outlet are obstructed.

ATTENTION

• When removing the air filter, do not touch the metal parts of the device. Sharp edges can cause cuts.
• Do not use water to clean the inside of the air conditioner. Water can destroy the insulating layer leading to an electric shock.
• Before cleaning the device, check that it has been disconnected from the power supply and that the circuit breaker is in the “off” position.
• Do not clean the filter with water hotter than 40°C/104°F. Shake the water off the filter and then place it in a dry, shaded place until it is dry. Do not expose the filter to direct sunlight as it may shrink.

PART 4. TROUBLESHOOTING

SYMPTOMS THAT DO NOT INDICATE DEVICE FAILURE
Symptoms that do not indicate device failure
The following phenomena may occur during the correct operation of the device.

1. Air conditioner protection system.
   Compressor protection
   • The compressor cannot start running for 3-4 minutes after it is finished.
   Cold air flow prevention (cooling and heating units only)
   • The unit is designed not to blow out cold air during heating operation when the heat exchanger is in one of the following situations and the set temperature is not reached.
   A) The heating process has only just started.
   B) Defrosting process is running.
   C) The outside temperature is outside the operating range of the device.
   • The fan of the indoor and outdoor units stops during the defrosting process (Cooling & Heating units only).
   Defrosting (cooling and heating units only)
   • Frost that appears on the outdoor unit during heating operation in low outdoor temperature and high air humidity can significantly reduce the performance of the unit.
   • In this case, the unit will stop heating and go into defrosting mode.
   • Defrosting time can vary from 4 to 10 minutes depending on the outside temperature and the amount of frost formed.

2. White fog escaping from the indoor unit
   • Due to the large temperature difference between the air inlet and outlet, and the high relative humidity, fog may come out of the indoor unit in cooling mode.
   • Fog may also occur during heating operation, due to the heating of defrost water.

3. Suspicious sounds
   • During operation, or immediately after stopping the compressor, you may hear a slight hissing sound.
   This sound is produced by the flowing refrigerant.
   • You may also hear a faint „shooting” noise during operation or right after the compressor stops. This is due to the thermal expansion of the plastic parts of the device, which are affected by changing temperatures.
   • After connecting the indoor unit to the power supply, the noise of the louvers returning to the position before the power was disconnected may be heard.

4. Dust blown out of the air conditioner
   This is a natural phenomenon that occurs after a long time of not using it, or when you first turn on the air conditioner.

5. Specific smells emanating from the indoor unit
   The air conditioner emits smells that have penetrated it from building materials, furniture or cigarettes.

6. The air conditioner automatically changes the operation mode from cooling or heating (only for cooling and heating units) to ventilation
   When the set temperature is reached, the compressor turns off and the air- conditioner enters the ventilation mode. The compressor will restart when the temperature increases during cooling or drops during heating (only for cooling and heating units) to the set value.

7. Water condensation
   Water may condense on the surface of the indoor unit operating in conditions of high relative humidity (over 80%). In this case, set the maximum opening angle of the horizontal louvers and run the fan at high speed.

8. Heating mode
   An air conditioner in heating mode draws heat from the environment via the outdoor unit and releases it using the indoor unit. A drop in the outside air temperature will reduce the amount of heat transported.
   At the same time, the heat load on the air conditioner increases due to the increased temperature difference between the indoor and outdoor units. If the air conditioner is unable to provide a comfortable temperature, we recommend using an additional heating device.

9. Automatic resume function
   • Power failure will interrupt the air conditioner operation. The operation indicator of indoor units not equipped with the resume function will flash after recovery of power. Pressing the ON/OFF button on the  wireless controller will then enable the device to be turned on again.
   • In the case of units equipped with the auto-wake-up function, the device that has been recharged will restart automatically and start working with the previous settings.

Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. lf in doubt  consult the manufacturer’s technical department for assistance. The following checks shall be applied to installations using flammable refrigerants: – the charge size is in accordance with the room size within which the refrigerant containing parts are installed;

• the ventilation machinery and outlets are operating adequately and are not obstructed;
• if an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;
• marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;
• refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance which may corrode refrigerant containing components, unless the components are constructed of materials which are inherently resistant to being corroded or are suitably protected against being so corroded.

1. 9 Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. lf a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. lf the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be reported to the owner of  the equipment so all parties are advised. lnitial safety checks shall include:

• that capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;
• that there no live electrical components and wiring are exposed while charging, recovering or purging the system;
• that there is continuity of earth bonding.

REPAIRS TO SEALED COMPONENTS
2.1. During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. lf it is absolutely necessary to have an electrical
supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
2.2. Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is affected. This shall include damage to  cables, excessive number of connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.
Ensure that apparatus is mounted securely.
Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose of preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specifications.
NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment.
lntrinsically safe components do not have to be isolated prior to working on them.
REPAIR TO INTRINSICALLY SAFE COMPONENTS
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted tor the equipment in use.
lntrinsically safe components are the only types that can be worked on while live in the presence of a flammable atmosphere. The test apparatus shall be at the correct rating.
Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.
CABLING
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans.
DETECTION OF FLAMMABLE REFRIGERANTS
Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide torch (or any other detector using a naked flame} shall not be used.
LEAK DETECTION METHODS
The following leak detection methods are deemed acceptable for systems containing flammable refrigerants.
Electronic leak detectors shall be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need recalibration. (Detection equipment shall be calibrated in a refrigerant-free area.) Ensure  that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the

REMOVAL AND EVACUATION
When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be used. However, it is important that best practice is followed since flammability is a  consideration. The following procedure shall be adhered to: remove refrigerant; purge the circuit with inert gas; evacuate; purge again with inert gas; open the circuit by cutting or brazing.
The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be “flushed” with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or  oxygen shall not be used for this task. Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally  pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system.
When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation is absolutely vital if brazing operations on the pipework are to take place. Ensure that the outlet tor the vacuum pump is not close to any ignition sources and !here is ventilation available.

CHARGING PROCEDURES
In addition to conventional charging procedures, the following requirements shall be followed. Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimise the amount of refrigerant contained in them. Cylinders shall be kept upright. Ensure that the refrigeration system is earthed prior to charging the system with refrigerant. Label the system when charging is complete (if not already). Extreme care shall be taken not to overfill the refrigeration system. Prior to recharging the system it shall be pressure tested with OFN. The system shall be leak  tested on completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.
DECOMMISSIONING
Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. lt is recommended good practice that all refrigerants are recovered safely. Prior to the  task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant. lt is essential that 4 GB electrical power is available before the task is  commenced.
a. Become familiar with the equipment and its operation.
b. lsolate system electrically.
c. Before attempting the procedure ensure that: mechanical handling equipment is available, if required, for handling refrigerant cylinders;
d. All personal protective equipment is available and being used correctly; the recovery process is supervised at all times by a competent person;
e. recovery equipment and cylinders conform to the appropriate standards.
f. Pump down refrigerant system, if possible.
g. lf a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
h. Make sure that cylinder is situated on the scales before recovery takes place.
i. Start the recovery machine and operate in accordance with manufacturer’s instructions.
j. Do not overfill cylinders. (No more than 80 % volume liquid charge).
k. Do not exceed the maximum working pressure of the cylinder, even temporarily.
l. When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off.
m. Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.

LABELLING
Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.

RECOVERY
When removing refrigerant from a system, either for servicing or decommissioning, il is recommended good practice that all refrigerants are removed safely. When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of cylinders for holding the total system charge are available. All cylinders to be used are designated for the recovered  refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure relief valve and associated shut-off valves in good working order. Empty  recovery cylinders are evacuated and, if possible, cooled before recovery occurs.
The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of flammable refrigerants. In addition, a set of  calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using the recovery machine, check that il is in  satisfactory working order, has been properly maintained and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult manufacturer if in doubt.
The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant Waste Transfer Note arranged. Do not mix refrigerants in recovery units and especially not in  cylinders.
lf compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that flammable refrigerant does not remain within the lubricant. The evacuation  process shall be carried out prior to returning the compressor to the suppliers. Only electric healing to the compressor body shall be employed to accelerate this process. When oil is drained from a system, il shall be  carried out safely.
