Dear customer, you have chosen a high-quality product. Here are a few tips to help you enjoy this product: After transportation: As the appliance works with refrigerant, improper transportation can sometimes occur despite careful instructions on the packaging. We therefore ask you to leave the appliance upright for at least 4 hours to allow the refrigerant to settle properly in the appliance. In case of any problems: We hope that the appliance meets your expectations! Should there be any cause for complaint despite the greatest possible care, please contact us briefly, as we are very concerned about your satisfaction and would like to clear up any misunderstanding. During the first operation: Attention: Please check that the sealing plug (for using the collection container), which is located at the back of the appliance, is screwed on tightly! Otherwise, water may leak out from underneath your appliance. As the inner pipes come into contact with moisture for the first time, it can take up to approx. 3 hours for liquid to collect in the collection container, depending on the room humidity.

Start-up time / delay:
To protect the compressor, it does not switch on again immediately after the appliance has stopped operating or there has been an interruption in operation (e.g. emptying the condensation tank). The compressor is initially in a so- called “protection mode” for approx. 3 minutes, in which only the fan runs before the compressor switches on again.
Room humidity and dehumidification performance:
If you would like to check the room humidity and the associated dehumidification performance with your own humidity meter (hygrometer), please ensure that this humidity meter is not attached to a wall, as this will falsify the true humidity content of the room air. See also the explanations under Troubleshooting!

Important safety instructions for repairing an appliance with R290 refrigerant:
1. Check the surroundings
Before you start working on systems that contain flammable refrigerants, safety checks are required to ensure that the risk of ignition is minimized. When repairing the refrigerant system, the following safety precautions must be observed and complied with before any work is carried out on the system.
Procedure
The work must be carried out in a controlled manner to minimize the risk of flammable gases or vapors being present during the execution of the work.
2. General work area
All maintenance personnel and other persons in the vicinity must be instructed on the type of work to be carried out. Work in confined spaces must be avoided. The area around the work area must be cordoned off. Ensure that the conditions in the work area have been made safe by checking the flammable material.
3. Check for the presence of refrigerants
The area must be checked with a suitable refrigerant detector before and during the work to ensure that the technician is aware of possible flammable atmospheres. Ensure that the refrigerant detector used is suitable for working with flammable refrigerants, e.g. non-sparking, adequately sealed and intrinsically safe.
4. Presence of a fire extinguisher
If hot work is to be carried out on the refrigerant equipment or associated parts, suitable fire extinguishing equipment must be readily available. Ensure that a dry powder fire extinguisher or a CO2 fire extinguisher is nearby.
5. No ignition sources
Persons carrying out work in connection with a refrigerant system which involves exposure to pipework containing or having contained flammable refrigerants must use ignition sources in such a way that they cannot cause a fire or explosion hazard. All possible ignition sources, including cigarette smoking, should be kept sufficiently away from the site of installation, repair and disposal during which the flammable refrigerant may be released into the surrounding area. Prior to work, the area around the equipment must be inspected to ensure that there are no flammable hazards or ignition risks. “No Smoking” signs must be posted.
6. Ventilated area
Ensure that the work area is outdoors or that it is sufficiently ventilated before interfering with the system or carrying out hot work. Sufficient ventilation must be ensured for the entire duration of the work to be carried out. The ventilation should safely disperse any refrigerant released and preferably discharge it externally into the atmosphere.

7. Testing the refrigerant equipment
If electrical components are replaced, they must be suitable for the purpose and have the correct specification. The manufacturer’s guidelines for maintenance and repair must be observed and followed at all times. If in doubt, contact the manufacturer’s technical department for assistance. The following tests must be applied to installations containing flammable refrigerants:
– The filling quantity is in accordance with the room size within which the parts containing refrigerant are installed;
– The ventilation equipment and the ventilation outlets are running properly and are not blocked.
8. Testing of electrical devices
Before repairing and maintaining electrical components, preliminary safety checks and inspections must be carried out on the components. If there is a defect that could jeopardize safety, the appliance must not be connected to the mains until the defect has been rectified. If the defect cannot be repaired immediately but operation must continue, an adequate temporary solution must be found. This must be reported to the owner of the equipment so that all parties are informed. The preliminary safety checks must include Capacitors must be discharged; this should be done in a safe manner to avoid the possibility of sparking. No live components and wiring must be exposed when filling, restoring or flushing the system. Continuity of the earth connection.
9. Repairs to hermetically sealed components
During repair of hermetically sealed components, all power to the appliance must be disconnected before removing sealed covers etc. If it is essential that power is supplied to the appliance during maintenance, a permanent leak detection system must be in place to warn of a potentially dangerous situation. Particular attention must be paid to the following point to ensure that when working on electrical components, the enclosure is not modified in such a way that the degree of protection is impaired. This includes damage to cables, an excessive number of connections, terminals that do not comply with the original specification, damage to seals, improper fitting of sealing screws, etc. Make sure that the appliance is securely mounted. Ensure that seals or sealing material are not so worn that they no longer serve their purpose to prevent the ingress of flammable atmospheres. Replacement parts must be in accordance with the manufacturer’s specifications.
NOTE: The use of silicone sealants may hinder the effectiveness of some leak detectors. Intrinsically safe components do not need to be sealed before working on them.
10. Repair of intrinsically safe components
Do not apply a permanent inductive load or capacitive load to the circuit without ensuring that this does not exceed the permissible voltage and current for the equipment being used. Intrinsically safe components are the only types that can be worked on while connected to the mains in the presence of a flammable atmosphere. The test equipment must have the correct ratings. Replace components only with parts specified by the manufacturer. Other parts may cause the refrigerant to ignite in the atmosphere due to a leak.

11. Cabling
Check that the cabling is not subject to wear, corrosion, excessive pressure, vibrations, sharp edges or other harmful environmental effects. The test must also take into account the effects of ageing or continuous vibration from sources such as compressors or fans.
12. Detection of flammable refrigerants
Under no circumstances should potential ignition sources be used when searching for or detecting refrigerant leaks. A halogen searchlight (or any other search device that uses naked flames) must not be used.
13. Leak detection methods
The following leak detection methods are considered acceptable for systems containing flammable refrigerants. Electronic leak detectors must be used to detect flammable refrigerants, but their sensitivity may not be sufficient or they may need to be recalibrated. (Detection equipment must be calibrated in a refrigerant-free area.) Ensure that the leak detector is not a potential ignition source and that it is suitable for the refrigerant used. Leak detection equipment must be set to a percentage of the lower explosion limit and must be calibrated to the refrigerant used and the adequate percentage of the gas (25% maximum) must be confirmed. Leak detection fluids are suitable for use with most refrigerants, but the use of cleaning agents containing chlorine must be avoided as chlorine can react with the refrigerant and degrade the copper piping. If a leak is suspected, remove/extinguish all naked flames. If a refrigerant leak is detected that requires brazing, all refrigerant must be recovered from the cooling system or isolated (by shutting off valves) in a part of the system remote from the leak. Oxygen-free nitrogen must then be flushed through the system before and during the brazing process.
14. Removal and emptying
If you are intervening in the refrigerant circuit to carry out repairs – or for any other reason conventional methods must be used. However, it is important that best practice is always followed, as flammability must be taken into account. The following procedure should be followed:
– Remove the refrigerant – Flush the circuit with inert gas – Deflate – Flush again with inert gas – Open the circuit by cutting or soldering
The refrigerant charge must be prepared in the correct preparation cylinders. The system must be “purged” with oxygen-free nitrogen to keep the appliance safe. This process may need to be repeated several times. Compressed air or oxygen must not be used for this purpose. Purging can be achieved by intervening in the vacuum in the system with oxygen-free nitrogen and continuing to charge until the working pressure is reached and then releasing to atmosphere and finally drawing into a vacuum. This process must be repeated until there is no more refrigerant in the system. When the last filling with oxygen-free nitrogen takes place, the system must be vented to atmospheric pressure. This is absolutely necessary if soldering work has to be carried out on the pipework. Make sure that the outlet for the vacuum pump is not located near sources of ignition and that ventilation is available.

15. Filling process
In addition to conventional filling processes, the following requirements must be followed:
– Ensure that no contamination of the various refrigerants occurs when filling the equipment. Hoses or cables must be as short as possible to minimize the amount of refrigerant they contain.
– Cylinders must remain upright. – Ensure that the cooling system is earthed before filling the system with refrigerant. – Mark the system when filling is complete (if not already done). – Extreme care must be taken not to overfill the cooling system. – Before refilling the system, the pressure must be tested with oxygen-free nitrogen. The system
must be tested for leaks at the end of filling but before commissioning. A check leakage test must be carried out before leaving the site.
16. Decommissioning
Before carrying out this procedure, it is necessary that the technician is fully familiar with the equipment and its details. It is a recommended standard that all refrigerants are safely reconditioned. An oil and refrigerant sample must be taken prior to the task to be carried out in case analysis is required before the reclaimed refrigerant is reused. It is necessary that electrical power is available before the task is started.
a) Familiarize yourself with the equipment and its operation. b) Disconnect the system electrically. c) Make sure before you carry out the procedure;
– that mechanical handling equipment is available, if necessary, also for handling refrigerant cylinders;
– that personal protective equipment is available and worn properly; – that the reprocessing process is supervised by a competent person at all times; – that the reprocessing equipment and cylinders comply with the applicable standards.
d) Pump out the refrigerant system if possible. e) If a vacuum is not possible, create a manifold so that the coolant can be removed from the
various parts of the system. f) Make sure that the cylinder is on the scales. g) Start the treatment system and operate it according to the manufacturer’s instructions. h) Do not overfill the cylinders (no more than 80 % liquid filling capacity) i) Do not exceed the maximum working pressure of the cylinder, not even temporarily. j) When the cylinders have been properly filled and the process is complete, ensure that the
cylinders and equipment are immediately removed from site and that all shut- off valves on the equipment are closed. k) Recycled refrigerant must not be filled into other cooling systems unless it has been cleaned and tested.
17. Labeling
The equipment must be labeled to indicate that it has been decommissioned and that the refrigerant has been drained. The marking must be dated and signed. Ensure that there are markings on the equipment stating that the equipment contains flammable refrigerant.

18. Reprocessing When removing refrigerant from a system, either for maintenance or decommissioning, it is recommended as standard that all refrigerant is safely removed. When transferring refrigerant to cylinders, ensure that only suitable refrigerant recovery cylinders are used. Ensure that the correct number of cylinders are available to hold the total amount of refrigerant. All cylinders used must be suitable and marked for the reconditioned refrigerant (i.e. special cylinders for reconditioning refrigerant). The cylinders must have a pressure relief valve and a connected shut-off valve and be in good working condition. Empty reprocessing cylinders must be emptied of air and, if possible, cooled before reprocessing. The reprocessing plant must be in good working order with appropriate instructions concerning the equipment and must be suitable for the reprocessing of flammable refrigerants. In addition, a set of calibrated scales in good working order must be available. Hoses must be complete with leak-free and proper disconnect couplings. Before using the reconditioner, check that it is in good working order, that it has been properly maintained and that all associated electrical components are sealed to prevent ignition in the event of a refrigerant leak. If in doubt, contact the manufacturer. The reconditioned refrigerant must be returned to the refrigerant supplier in the correct reconditioning cylinder and the appropriate disposal certificate must be arranged. Do not mix refrigerant in remanufacturing units and especially not in cylinders. If a compressor or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to ensure that no flammable refrigerant remains in the lubricant. The evacuation process must be carried out before returning the compressor to the supplier. Only electrical heating of the compressor housing may be used to accelerate this process. When draining oil from a system, this must be done in a safe manner. 19. Electrical components Electrical components that can generate arcs or sparks and that are not considered ignition sources due to compliance with 22.116.1 letters b), c), d) or f) may only be replaced by parts specified by the appliance manufacturer. Replacement with other parts may lead to ignition of the refrigerant in the event of a leak.

Troubleshooting:

The appliance does not dehumidify enough / Too little water collects in the condensation tank

Please remember that the primary aim is not to extract as much condensation water as possible, but to dry the room air or ceilings, walls and inventory and/or keep them dry!

Please also bear in mind that the dehumidifier can only remove moisture from the air and only indirectly from materials. Depending on the condition of the ceilings, walls and furnishings, it can take several weeks for them to release the stored moisture back into the air! For this reason, we also recommend that if you use your own humidity meter (hygrometer), you place it as freely as possible and at some distance from walls and ceilings, as otherwise the humidity value determined in the room air will be falsified!

As with all dehumidifiers, the dehumidification performance is decisively influenced by the following factors:

A) Humidity content of the room air and B) Heat/Temperature in the room.

To be on the safe side, here is an excerpt from the dehumidification table at DAUERBETRIEB:

32 degrees and 80% r.h. = approx. 15 liters 30 degrees and 80% r.h. = approx. 14 liters 20 degrees and 80% r.h. = approx. 7 liters 15 degrees and 80% r.h. = approx. 6 liters 10 degrees and 80% r.h. = approx. 5 liters
5 degrees and 80% r.h. = approx. 3 liters

at 90% r.h. = approx. 16 liters at 90% r.h. = approx. 15 liters at 90% r.h. = approx. 8 liters at 90% r.h. = approx. 7 liters at 90% r.h. = approx. 6 liters at 90% r.h. = approx. 5 liters

at 60% r.h.= approx. 8 liters at 60% r.h. = approx. 7 liters at 60% r.h. = approx. 5 liters at 60% r.h. = approx. 4 liters at 60% r.h. = approx. 3 liters at 60% r.h. = approx. 2 liters

All figures are approximate per day (fluctuation tolerance) when measured directly at the appliance inlet and of course these values only apply if the temperature and humidity content remain constant!

Despite the hose connection, most of the water runs into the condensation tank

Check that the condensation hose has a gradient and is neither kinked nor blocked. Also check that the dehumidifier is standing level and that the castors are not necessarily in the joints on a tiled floor.
