This shall include damage to cables, excessive numble of connection, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.
   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.

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 leaks. A halide torch (or any other detector using a naked flame) shall not be used

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-calibrated.(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 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 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 processing 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 minimize 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 is 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 is 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 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. Labeling
    Equipment shall be labeled 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 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 labeled 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 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 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 of 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 drained form a system, it shall be carried out safely.

FREQUENTLY ASKED QUESTIONS & TROUBLESHOOTING

Are the dehumidifiers costly?

For about the first month of use, the dehumidifier operates intensively. This will gradually decrease within time, since the dehumidifier will have been calibrated in its working environment. Condensed households may sometime be significantly expensive to heat. The use of a dehumidifier may lower energy costs.

Where should thedehumidifier beplaced ideally?

For optimal results, it is suggested that the dehumidifier is placed in a central area. Doors within the household should be open in order for the dehumidifier to enhance its operation.

Can the air filter be replaced by another type of filter, such as HEPA?

The dehumidifier’s filter cannot be replaced by any other type of filter since it is specifically designed to operate with this unit.

Which is the appropriate room humidity level?

Maintaining a proper home humidity level is essential for your well-being and that of your household. Extreme fluctuations cause adverse effects on both; low humidity may cause respiratory problems and damage on wooden doors, windows, and furniture, and make you vulnerable to electric shocks due to increased static electricity. On the other hand, high humidity may promote mold growth, serving as breeding grounds for various bacteria and resulting in poor health and also a damaged home. The ideal humidity levels fluctuate etween 45% to 55%.

Why does condensation persist on windows even with dehumidifier’s use?

When the desired humidity level is reached, there is a possibility of partial humidity formation on windows. This occurs due to the temperature variation between the window and the external weather conditions. • Operating the dehumidifier should significantly reduce condensation formation on windows.

Why am I not ableto set the desired humidity level by use of the control panel?

How much time isneeded to dry my clothes?

The exact time needed to dry clothes depend on many factors, the room's temperature and size, the humidity level, the moisture of the clothes etc., so there is no standard time since of these variable factors mentioned above To shorten the time period, place the dehumidifier in a small room with all doors and windows shut. The smaller the room the more efficient the drying operation will be.

The dehumidifier is not a chilling device.What could be the cause of cold air being extracted?

The dehumidifier operates by intaking condensed air removing any moisture and sending it back in the area it operates. If you are standing near the dehumidifier while operating you may feel that the air coming out of the fan is cooler due to the diffusion. In reality, it is at the same roomtemperature but with less humidity.

Why does the dehumidifier operate a total of 9 hours under Dryer’s mode?

The dehumidifier operates for a period of 9 hours under the Dryer’s mode function which is the appropriate period of time to manage dry clothes and the desired humidity levels. The dehumidifier will stop operating after 9 hours, in order to avoid any excessive air dryness that may result in damaging the clothes.

Why is the dehumidifier making some noise from time to time?

When the compressor starts or stops operating, the unit may make a loud noise, it is normal.

Why does the dehumidifier not operate while the humidity of the room has increased?

When the set humidity is reached, the Energy Savings function is automatically activated during which the digital control display of the device may show increased humidity levels. This is because the fan is not operating. After the predetermined timeframe and if the humidity levels have increased, the device will resume dehumidification.
