This appliance contains refrigerant gas R290
(for using R290/R32 refrigerant only)
See transport regulations
See local regulations
The storage of equipment should be in accordance with the manufacturer's instructions.
Storage package protection should be constructed such that mechanical damage to the equipment inside the package will not cause a leak of the refrigerant charge.
The maximum number of pieces of equipment permitted to be stored together will be determined by local regulations.
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.
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.
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 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.
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:
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 for the vacuum pump is not close to any ignition sources and there is ventilation available.
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.
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.
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.
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.
Never attempt to personally perform maintenance interventions that imply opening the machine: the presence of charged components and the gas contained in the refrigeration circuit make these operations particularly dangerous. Always contact a specialised technical assistance centre.
Always unplug the appliance prior to effecting any operation. Prevent water from entering through the upper grille. Do not obstruct the air flow. Never use the dehumidifier outdoors. Do not use the appliance in places where corrosive vapours or dangerous substances are present. Do not place objects on top of the appliance. Before removing the appliance, make sure that the condensate collector tank is empty. Do not pull on the power cable to turn the appliance off. Never open the dehumidifier body. After turning the appliance off, wait a few minutes before turning it back on. Do not use the appliance on inclined surfaces. Do not use extensions for the power cable. |
The dehumidifier does not operate at temperatures below 5°C or above 32°C.
If necessary, contact your dealer or the manufacturer's technical assistance centre for further information.
Dirt may sometimes build up in the dehumidifier after it has been used for several seasons, resulting in a loss of efficiency. It is important to regularly empty the condensate water deposited in the appliance and periodically perform maintenance operations; contact the local dealer for technical assistance.
A certain amount of water vapour is always present in the air: the air's capacity to withhold water vapour increases with its temperature.
For example, at a temperature of 26°C, the maximum humidity content is 21.4 g of water vapour per kg of air, while at 30°C, the maximum humidity content evaporator condenser is 27.2 g of water vapour per kg of air. In actual fact, the maximum humidity contents constitute extreme cases which do not occur at our latitudes. In these conditions, air is said to be 'saturated' (i.e. it cannot contain any more humidity) and the water vapour begins to condense. 'Relative humidity' refers to the ratio between the air's actual humidity and the maximum possible humidity content at that particular temperature.
For example, if said temperature were to be 26°C, the actual humidity content would be 10.7 g of water vapour for each kg of air, and the relative humidity would be:
Relative humidity is always expressed as a percentage value (%). Apart from natural causes, the air's humidity in enclosed spaces can increase due to the number of people present, the activities being performed, etc. Both too little and too much humidity are harmful to the human body, for opposite reasons, and should thus be avoided.
Detected room temperature | Set relative humidity |
T ≤ 18°C | 55% |
18°C < T < 25°C | 50% |
T ≥ 25°C | 45% |
Do not touch the selector with wet hands (risk of personal injury due to electrocution). Do not start or stop the appliance by simply plugging it into the power socket or unplugging it (risk of personal injury due to electrocution). Avoid prolonged direct exposure to the air flow (risk of personal injury due to sensitisation of the skin). |
This function enables the dehumidifier to restart, after a power failure, from the last stored settings.
Prevents the evaporator from frosting, thereby extending the dehumidifier's life and enhancing energy saving. When this function is active, the fan continues to run while the compressor stops and 'P1' appears on the display.
The dehumidifier stops when the condensate collection tank is full or incorrectly positioned. 'P2' displays together with indicator light .
NOTE: when the compressor stops, it is necessary to wait 3 minutes before it restarts.
Hold the PURE button down for more than 3 seconds to enable this function. It sets the fan speed and hours of operation of the dehumidifier (up to 4h) in relation to the measured actual humidity. This maximises occupant comfort while reducing the risk of mould and bacterial growth.
To disable the function, hold the PURE button down for more than 3 seconds or select an operating mode with the MODE button.
Hold the TURBO button down for more than 3 seconds to enable this function; the displays reads SC for 5 seconds and then clears.
The SELF CLEAN function initiates as soon as the dehumidifier is switched off, and runs for 15 minutes; the display reads SC while the function is active.
The function cleans and dries the heat exchangers with ventilation/dehumidification cycles, thus keeping them in perfect working order.
To deactivate SELF CLEAN, hold down the TURBO button for 3 seconds; SC flashes on the display for 5 seconds and then clears.
This function significantly reduces the dust, bacterial and allergen content of the room, using the HEPA (High Efficiency Particulate Air) filter supplied with the dehumidifier.
Press the PURE button to activate the AIR PURIFIER function; all other modes and special functions are inhibited while it is running. Make sure you have fitted the HEPA filter as indicated in fig. A.
Incorrectly installing the filter or forcing it into place can cause the dehumidifier to malfunction, overheat and even fail. |
The dehumidifier can discharge the condensate water in two different ways:
The condensate water falls directly in the tank located in the lower section of the dehumidifier. When the tank is full, the dehumidifier automatically shuts down and the displays shows "P2" and the logo.
PROCEDURE FOR EMPTYING THE TANK:
Allows for discharging the condensate water without letting it fall into the collection tank. This function is particularly useful when the dehumidifier must be operated for long periods, making it difficult to empty the tank continuously.
INSTRUCTIONS
To restore standard draining into the tank, make sure to refit the rubber cap into the hole on the rest of the unit. |
For the correct operation of your dehumidifier, we advise you to observe the distances shown in Fig. D.
Position the dehumidifier on a stable, smooth and horizontal surface.
The appliance can be moved using the wheels. Before moving the appliance, disconnect the power supply and empty the condensate collection tank.
Before cleaning the appliance, unplug it and disengage the automatic switch.
Clean the condensate collection tank regularly (every 2-3 weeks) in order to prevent mould and bacteria build-up. Use water and non-aggressive detergents.
Cleaning the filter regularly (to be performed at least every 30 days) is essential to ensure optimal dehumidifier performance.
