• Servicing shall only be performed as recommended by the equipment manufacturer. Maintenance and repair requiring the assistance of other skilled personnel shall be carried out under the supervision of the person competent in the use of flammable refrigerants.

1. Transport of equipment containing flammable refrigerants
   See transport regulations

2. Marking of equipment using signs
   See local regulations

3. Disposal of equipment using flammable refrigerants
   See national regulations.

4.   Storage of equipment/appliances
   The storage of equipment should be in accordance with the manufacturer’s instructions.

5. Storage of packed (unsold) equipment
   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.

6. Information on servicing

7. 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.

8. 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.

9. 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.

10. 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.

11. 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.

12. 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.

13. 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.

14. 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.

15. 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.

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 isabsolutely 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.

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, 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 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.
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.
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. 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.

• Become familiar with the equipment and its operation.

•  Isolate system electrically.

• 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.

• Pump down refrigerant system, if possible.

•  If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.

• Make sure that cylinder is situated on the scales before recovery takes place.

•  Start the recovery machine and operate in accordance with manufacturer’s instructions.

• Do not overfill cylinders. (No more than 80 % volume liquid charge).

•  Do not exceed the maximum working pressure of the cylinder, even temporarily.

•  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.

•  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, 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.

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.

HUMIDITY CONCEPTS

AIR HUMIDITY
A certain amount of water vapour is always present in the air: the air’s capac-ity 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 is 27.2 g of water vapour per kg of air. In actual fact, the maximum humid-ity 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 hu-midity 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.

CAUTION

Incorrectly installing the filter or forcing it into place can cause the dehumidifier to malfunction, overheat and even fail.

CONDENSATE DISCHARGE

The dehumidifier can discharge the condensate water in two different ways:
DISCHARGE INTO TANK
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:

• * Pull out the tank slightly using the appropriate handles on the sides (Fig. A).

  • Pull the tank out fully while being careful not to spill the condensate water.
  • Do not place the tank on the ground as its irregular underside may cause the water to spill out.
  • Empty out the water.
  • Put the tank back into its housing. The dehumidifier will automatically start functioning again.

WARNING:

• *  Do not remove the float (located inside the tank) when emptying

  • Make sure to put the tank properly back into its housing (after having emptied it).
  • Incorrectly fitting the tank can stop the dehumidifier starting (make sure the “P2” has cleared from the display). Before removing the tank, it is advisable to tap the top part of the dehumidifier a few times to ensure that all the water has fallen into the tank. A few drops of water may nonetheless drip down once the tank has been pulled out.
  • Before undertaking any operation on the appliance, make sure that the power supply has been disconnected.

CONTINUOUS DRAINAGE
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

• *  Remove the rubber cap from the right-hand outlet located on the rear of the appliance (Fig. B).

  •  Connect the hose (not included) with 13,5 mm internal diameter to the outlet (Fig.C). Make sure that the other end of the hose terminates at
• water collection point lying lower than the discharge outlet.
  • Switch the appliance on.

CAUTION:

To restore standard draining into the tank, make sure to refit the rubber cap into the hole on the rest of the unit.

POSITIONING TIPS

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 mov-ing the appliance, disconnect the power supply and empty the condensate collection tank.
BASIC MAINTENANCE
Before cleaning the appliance, unplug it and disengage the automatic switch.

CLEANING THE DEHUMIDIFIER

• `Clean the dehumidifier using a cloth dampened in lukewarm water (no more than 40°C) and neutral soap. Do not use solvents or aggressive detergents.
• Do not spray water directly onto the appliance.

CLEANING THE TANK
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 FILTERS

Dust filter

Cleaning the filter regularly (to be performed at least every 30 days) is essential to ensure optimal dehumidifier performance.

• * Remove the rear grille by raising the lower part and sliding it out downwards (Fig. E).

  • Remove the filter from the grille and clean it using a vacuum cleaner or wash it with lukewarm water and neutral detergent.
  • Dry it thoroughly (do not leave it exposed to sunlight).
  • Put the filter and grille back in place.

HEPA filter: High Efficiency Particulate Air
(Supplied with the dehumidifier, not pre-installed) Purifies the air and reduces dust, bacteria and allergens. – Replace the filter every 12 months of use.

END-OF-SEASON MAINTENANCE

1.  Remove any condensate water present in the tank.
2.  Clean the appliance, tank and dust filter.
3. Cover the appliance to protect it against dust.

1. Relative to operation at 30°C and 80% relative humidity.
2. Refrigerant loss contributes to climate change. In case of their release into the atmosphere, refrigerants with lower global warm-ing potential (GWP) have less impact on global warming compared to refrigerants with a higher GWP. This appliance contains a refrigerant fluid with a GWP of 3. In other words, if 1 kg of this refrigerant fluid were released into the atmosphere, the impact on global warming would be 3 times greater compared to 1 kg of CO2, over a period of 100 years. In no case whatsoever must the user attempt to intervene on the refrigerant circuit or dismantle the product. In case of need, please contact a qualified professional.
