The Refrigerant

  • To realize the function of the air conditioner unit, a special refrigerant circulates in the system. The used refrigerant is the fluoride R32, which is specially cleaned. The refrigerant is flammable and inodorous. Furthermore, it can lead to explosion under certain conditions. But the flammability of the refrigerant is very low. It can be ignited only by fire.
  • Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm to the ozonosphere. The influence upon the greenhouse effect is also lower. R32 has got very good thermodynamic features which lead to a really high energy efficiency. The units therefore need a less filling.

WARNING:
Do not use means to accelerate the defrosting process or to clean, other than those recommended by the manufacture.Should repair be necessary, contact your nearest authorized Service Centre.
The installation work shall be carried out by qualified personnel.
The appliance shall be stored in a room without continuously operating ignition
electric heater.)
Do not pierce or burn.

Specialist’s Manual

  • The following checks shall be applied to installations using flammable refrig-erants:’

    • 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 compo-nents, unless the components are constructed of materials which are inherently
  • resistant to being corroded or are suitably protected against being so corroded. 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 possi-bility of sparking;
    • that no live electrical components and wiring are exposed while charging, recover-ing or purging the system;
    • that there is continuity of earth bonding.
  • 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, IEC60335-2-40:2018 Annex DD.4.3 to DD.4.7 shall be completed prior to conducting work on the system.

  • 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.

  • 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.

  • 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 toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with all applicable refrigerants, i.e. non-sparking, adequately sealed or intrinsi-cally safe.

  • Presence of fire extinguisher
    If any hot work is to be conducted on the refrigerating 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.

  • No ignition sources
    No person carrying out work in relation to a refrigerating system which involves exposing any pipe work 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 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.

  • 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. 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.

  • Checks to electrical devices

    • that capacitors are discharged: this shall be done in a safe manner to avoid possi-bility of sparking;
    • that no live electrical components and wiring are exposed while charging, recover-ing or purging the system.
  • Repairs to sealed components
    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 servic-ing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
    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 the apparatus is mounted securely.
      Ensure that seals or sealing materials have not degraded to the point 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 can inhibit the effectiveness of some types of leak detection equipment. Intrinsically 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 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.

  • Cabling
    Check that cabling will not be subject to wear, corrosion, excessive pressure, vibra-tion, 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.

  • Leak detection methods
    Leak detection fluids are suitable for use with most refrigerants but the use of deter-gents containing chlorine shall be avoided as the chlorine may react with the refrig-erant and corrode the copper pipe-work.

  • 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.
    The following leak detection methods are deemed acceptable for all refrigerant systems.
    Electronic leak detectors may be used to detect refrigerant leaks but, in the case of flammable refrigerants, the sensitivity may not be adequate, or may need re-cali-bration. (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 refrig-erant and shall be calibrated to the refrigerant employed, and the appropriate percentage of gas (25% maximum) is confirmed.
    Leak detection fluids are also 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.
    NOTE: Examples of leak detection fluids ar

    • bubble method,
    • fluorescent method agents.
      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. Removal of refrigerant shall be according to clause IEC60335-2-40:2018 Annex DD.9 .
  • Removal and evacuation
    When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be used. However, for flammable refrigerants 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 with inert gas ;
    • open the circuit by cutting or brazing..
      The refrigerant charge shall be recovered into the correct recovery cylinders. For appliances containing flammable refrigerants other than A2L refrigerants, the system shall be purged with oxygen-free nitrogen to render the appliance safe for flammable refrigerants. This process may need to be repeated several times. Com-pressed air or oxygen shall not be used for purging refrigerant systems.
      For appliances containing flammable refrigerants, other than A2L refrigerants, refrigerants purging shall be achieved by breaking the vacuum in the system with oxygen-free nitrogen 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 oxygen-free nitrogen charge is used, the system shall be vented down to atmo-spheric 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 potential ignition sources and that ventilation is available.
  • Charging procedures
    In additon 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 in an appropriate position according to the instructions.

  • Ensure that the refrigerating 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 refrigerating system.
    Prior to recharging the system, it shall be pressure-tested with the appropriate purg-ing gas. The system shall be leak-tested on completion of charging but prior to com-missioning. 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. 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 reuse 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.

  • Labelling
    Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. For appliances containing flammable refrigerants, 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, 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 are available. All cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (i.e. special cylin-ders 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 all appropriate refrigerants including, when applicable, flammable refrigerants. In ad- dition, 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 refrig-erants 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.

Operation Tips

Operation for comfort and economy

  • Do not overcool the room temperature. This is not good for health and wastes electricity.
  • Keep blind or curtains closed. Do not let sunshine enter the room directly when the air con-ditioner is in operation.
  • Keep the room temp. stable Adjust the vertical and horizon-tal airflow direction to ensure a stable temperature in the room. Air can’t be discharged to the di-rection of air-in.GREE-GWF07DB-Window-type-Air-Conditioner-fig29
  • Make sure that the doors and windows are tightly closed. Avoid open-ing doors and windows as much as possible to keep air conditioning in the room.
  • Clean the air filter regularly. Blockages in the air filter re-duce dehumidifying effects. Clean the air filter at least once every two weeks.
  • Ventilate the room occasionally Since windows are kept closed, it is a good idea to open them and ventilate the room now and then. When starting the unit, curtains or windows should be closed to pre-vent the heat/cool leakage.GREE-GWF07DB-Window-type-Air-Conditioner-fig30

Troubleshooting guide

Fault phenomenon Trouble-shooting

Air conditioner does not operate at all.

|

*  Is there a power failure?

*  Is the plug out?

  • Is power fuse or switch off ?

  • Whether the voltage is too high or too low?

Cool or heat efficiency is not good.

| *  Is air inlet or outlet locking?

*  Is there any other heat/cool source in room?

  • Are air filters dirty very much?

  • Is indoor fan speed set at LOW?

  • Maybe the room is too hot/cool when the unit is started.

Foggy air flows out.

| * At COOL mode operation, sometimes there is foggy air flowing out of the unit, this is because the room humid air has been cooling rapidly.

  • The unit is normal while the indoor outlet is sending out some odor, because the inlet air may be mixed

with the smell of furniture and smoke.

The air conditioner operation is noisy.

|

  • For a noise that sounds like water flowing:

This is the sound of freon flowing inside the air conditioner unit.

  • For a noise that sounds like a shower:

This is the sound of the dehumidifying water being processed inside the air conditioner unit.

It seems that condensation is leaking from air conditioner.

|

  • Condensation occurs when the airflow from the air conditioner cools the warm room air.

Air conditioner does not operate for about 3 minutes when restart.

|

  • This is to protect the mechanism.

  • Wait about 3 minutes and operation will begin.
