6. Information on servicing
   1)Checks to the area
   Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimised. For repair to the  refrigerating system, the following precautions shall be complied with prior to conducting work on the system.
   2)Work procedure
   Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour being present while the work is being performed.
   3)General work area
   All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work in confined spaces shall be avoided. The area  around the workspace shall be sectioned off. Ensure that the conditions within the area have been made safe by control of flammable material.
   4)Checking for presence of refrigerant
   The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially flammable atmospheres.  Ensure that the leak detection equipment being used is suitable for use with flammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
   5)Presence of fire extinguisher
   If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available to hand. Have a dry  powder or CO2 fire extinguisher adjacent to the charging area.
   6)No ignition sources
   No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or has contained flammable refrigerant shall use  any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept  sufficiently far away from the site of installation, repairing, removing and disposal, during which flammable refrigerant can possibly be released to the surrounding space.  Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. No Smoking signs shall be displayed.
   7)Ventilated area
   Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue  during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.
   8)Checks to the refrigeration equipment
   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. If 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.
   9)Checks to electrical devices
   Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise safety,  then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If 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.
   Initial 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.

7. Repairs to sealed components
   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. If  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)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. Intrinsically safe components do not have to be isolated prior  to working on them.

8. 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 for the equipment in use.
   Intrinsically 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.

9. 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.

10. 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.

11. 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 re-calibration. (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 refrigerant employed and the appropriate percentage of gas (25 % maximum) is confirmed. Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work. If a leak  is suspected, all naked flames shall be removed/ extinguished. If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the  system, or isolated (by means of shut off valves) in a part of the system remote from the leak. Oxygen free nitrogen (OFN) shall then be purged through the system  both before and during the brazing process.

12. 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 pipe-work are to take place.
    Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is ventilation available.

13. 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.

14. Decommissioning
    Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. It 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. It is essential that electrical power is available before the task is commenced.
    a) Become familiar with the equipment and its operation.
    b) Isolate system electrically.
    c) Before attempting the procedure ensure that:
    Mechanical handling equipment is available, if required, for handling refrigerant cylinders;
    All personal protective equipment is available and being used correctly;
    The recovery process is supervised at all times by a competent person;
    Recovery equipment and cylinders conform to the appropriate standards.
    d) Pump down refrigerant system, if possible.
    e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
    f) Make sure that cylinder is situated on the scales before recovery takes place.
    g) Start the recovery machine and operate in accordance with manufacturer’s instructions.
    h) Do not overfill cylinders. (No more than 80 % volume liquid charge).
    i) Do not exceed the maximum working pressure of the cylinder, even temporarily.
    j) 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.
    k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.

15. 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.

16. Recovery
    When removing refrigerant from a system, either for servicing or decommissioning, it 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 is 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 it 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. If 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 heating to the compressor body shall be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely.

Vertical air flow adjustment (manually)

Airflow in vertical direction can be changed by adjusting horizontal louver manually when the unit is running.
NOTE: Adjusting angle of horizontal louver depends on models.

1. To avoid generating condensing water on the surface of horizontal louver, horizontal louver should not be at the maximum upwards or downwards angle position for a long time in cooling or drying mode.
2. Please adjust the horizontal louver by holding the convex part between the grooves.(if any)

Air Filter
The air filter behind the inlet grille should be checked and cleaned at least once every 2 weeks (or as necessary) to maintain optimal performance of the air conditioner.
How to remove the air filter
Turn off the unit, disconnect /unplug from the power supply.

1. Hold the slot under the front panel, then uplift it outwards, and remove the front panel.
2. Pinch the handle under the air filter and make the air filter arched, remove it from the slot from underside to upside.
3. Clean the filter with warm, soapy water. The water should be below 40 C to prevent distortion of the filter.
4. Rinse off and gently shake off excess water from the filter. Allow the filter to dry before replacing it. To prevent distortion of the filter, do not dry in direct sunlight.

Cabinet Cleaning

• Be sure to unplug the air conditioner to prevent shock or fire hazard. The cabinet and front may be dusted with an oil-free cloth or washed with a cloth dampened in a solution of warm water and mild liquid dishwashing detergent. Rinse thoroughly and wipe dry.
• Never use harsh cleaners, wax or polish on the cabinet front.
• Be sure to wring excess water from the cloth before wiping around the controls.
• Excess water in or around the controls may cause damage to the air conditioner.
• Plug in air conditioner.

NOTE: Never use water over 50°C, alcohol, gasoline, acid, solvent or brush to clean the front panel as this will damage the surface of the pad.
Winter Storage
If you plan to store the air conditioner during the winter, remove it carefully from the window according to the installation instructions. Cover it with plastic or return it to the original carton.
CAUTION **
NEVER operate the air conditioner without the air filter, as dust/dirt particles can contribute to equipment failure.**
Drainage
To treat condensed water will be as follows:

1. Bottom drainage. Connect drain hose to the bottom drain tray. It will slightly affect cooling performance, but will reduce the noise caused by spraying the condensed water.
   Note: Only optional for models with bottom drain hole. For pump heating, the bottom drainage must be choose.

2. Back drainage. Connect drain hose to the back drainage hole.
   It will slightly affect cooling performance, but will reduce the noise caused by spraying the condensed water.

3. Non-drainage. Block the drain hole(s) by rubber plug(s). The condensed water will be sprayed to condenser, and will improve the cooling performance.
   Installation procedures of bottom drainage:
   -Remove the rubber plug from the bottom of cabinet(if installed).
   -Take out the drain tray and screws from accessary.
   -Fix the drain tray onto the bottom of cabinet by screws.
   -Connect an extension drain hose (locally purchased) to the outlet of drain tray.
   Installation procedures of back drainage:
   -Fit the seal (provided as accessory) onto the drain joint.
   -Insert the drain joint to the back drainage hole, and rotate it by 90°to be well fitted.
   -Connect an extension drain hose (locally purchased) to the drain joint.
   -Make sure block the bottom drain hole by rubble plug.
   Note: Drain hose is locally purchased according to installation length request. NOTE: If you choose non-drainage when cooling, both the bottom and the back drain holes of the unit should be inserted with rubber plugs. When you choose non-drainage the air conditioner will be perfect cooling efficiency, but big noise may be caused by spraying the condensed water. Does not recommend to use.
   NOTE: The rated cooling performance is tested under non-drainage status.
   NOTE: Make sure that water will not leak from the surrounding area when rubber plug and joint were used. Please seal it in case leakage is found.

INSTALLATION INSTRUCTIONS

Select the best location
NOTE: Before installing, remove all packaging from inside the carton, along with any inserts placed into the side louvers.

1. To avoid vibration and noise, make sure the unit is installed securely and firmly.

TROUBLESHOOTING

Troubleshooting Tips
Save time and money! Review the chart below first and you may not need to call for service.
Normal Operation

• You may hear a pinging noise caused by water being picked up and thrown against the condenser on rainy days or when the humidity is high. This design feature helps remove moisture and improve efficiency.

• You may hear the thermostat click when the compressor cycles on and off.
  Water will collect in the base pan during high humidity or on rainy days .The water may overflow and drip from the outdoor side of the unit.

• The fan may continue to operate when the compressor has cycled off.

Abnormal Operation

Air conditioner
does not start| The air conditioner is unplugged.| Make sure the air conditioner plug is pushed completely into the outlet and switched on.
The fuse is blown/circuit breaker is tripped.| Check the house fuse/circuit breaker box and replace the fuse or reset the breaker.
Power failure.| If power failure occurs, switch off and disconnect/unplug the power cord.  When power is restored, reconnect (plug in) the power cord, switch on the  power and wait 3 minutes to restart the air conditioner to prevent tripping of the compressor overload.
Air conditioner does not  cool as it should| Airflow is restricted .| Make sure there are no curtains, blinds, or furniture blocking the front of the air conditioner.
The air filter is dirty.| Clean the filter at least every 2 weeks. See the operating instructions section.
The room may have been hot.| When the air conditioner is first turned on you need to allow time for the room to cool down.
Cold air is escaping.| Check for open furnace floor registers and cold air returns. Set the air conditioner’s vent to the closed position.
Cooling coils have iced up.| See Air Conditioner Freezing Up below.
Air conditioner freezing up| Ice blocks the air flow and stops the air conditioner from cooling the room.| Set the fan at MED or HIGH until  the ice melts.
