DESCRIPTION OF COMPONENTS
FUNCTION EXPLANATION
OPERATING INSTRUCTIONS
- Start Operation1) Place the dehumidifier in an upright position on a flat, stable, and heat-resistant surface. Make sure there is nothing flammable or heat-sensitive within 100cm (39 inches).Operating the appliance in any other position could cause a hazard.
2) Insert the power plug into a suitable power socket. The dehumidifier is suitable for operation on an electricity supply having the same voltage as that shown on its rating label (located at the rear of the appliance).3) Make sure the water tank is inserted correctly (after switching on the machine for the first time the “Bucket Full” light may illuminate, if so pull out the water tank, check the “float” lever is able to move freely, then return the water tank to the correct position). - When “Bucket Full” Lamp Is OnWhen the water tank is full, the indication lamp will light up and the dehumidifier will stop operating. Remove the water from the tank, then place the water tank back to its proper position. The machine will start operating again.
- DEFROSTWhen operating in low temperatures (below 20ºC) the surface of the condensing coil may accumulate frost and affect the efficiency of the dehumidifier. When this appens, the machine will go into periodic defrost mode automatically. This is quite normal. Defrost lamps will come on during the defrost period. Defrost time may vary depending on the room temperature and humidity.
2) Insert the power plug into a suitable power socket. The dehumidifier is suitable for operation on an electricity supply having the same voltage as that shown on its rating label (located at the rear of the appliance).
3) Make sure the water tank is inserted correctly (after switching on the machine for the first time the “Bucket Full” light may illuminate, if so pull out the water tank, check the “float” lever is able to move freely, then return the water tank to the correct position).
CONTINUOUS DRAINAGE OPTIONS
Continuous drainage is an additional method of removing collected water from the dehumidifier. Instead of manually emptying the water tank, the User may choose this method to allow the water to bypass the water tank and flow directly from the dehumidifier via a drain hose or pump out drain hose. The following steps are useful when there are good conditions for drainage near the dehumidifier.Option1
INSTALLING DRAINAGE HOSE
When using continuous drainage, the drain hose must be placed horizontally below the level of the drainage hole. Avoid uneven ground and kinking the hose.
Option 2Automatic pump-out operations Installation:
- Connect the attached continuous drainage adaptor (fig. 1) to the drain hole on rear panel (fig. 2).
- When the dehumidifier is in operation the water will drain continuously and automatically.
Remove pump-out drain hose:
- Press the drain hole (fig.3) on the unit.
- The continuous drainage adaptor will detach from the unit.

INSTRUCTION FOR REPAIRING APPLIANCES CONTAINING R 290 AUTHORISED PERSONS ONLY!
- Checks to the areaPrior to beginning any authorized work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimized. The following precautions shall be complied with prior to conducting work on the system.
- Work procedureWork shall be undertaken under a controlled procedure so as to minimize the risk of flammable gas or vapor being present while the work is being performed.
- General work areaAll maintenance staff and others working in the local area shall be instructed on the nature of the 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.
- Checking for presence of refrigerantThe 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. nonsparking, adequately sealed, or intrinsically safe.
- Presence of fire extinguisherIf any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available on hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging area.
- No ignition sourcesNo person carrying out work in relation to a refrigeration system that involves exposing any pipework that contains or has contained flammable refrigerant shall use any sources of ignition in such a manner that is 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.
- Ventilated areaEnsure 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 and released refrigerant and preferably expel it externally into the atmosphere.
- Checks to the refrigerant equipmentWhere 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 the parts are installed;– the ventilation machinery and outlets are operating adequately and are not obstructed;
- Checks to electrical devicesRepair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise the 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 the possibility of sparking.– that there are 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 componentsDuring 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 servicing, 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, an 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: 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 componentsDo not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and currently 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.
- CablingCheck 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 vibrations 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 methodsThe 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 s 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 ut 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 asked lames shall be removed/extinguished.If leakage of refrigerant is found which requires brazing, all of the refrigerants shall be recovered from the system, or isolated by means of shit 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 evacuationWhen breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be used. However, it is important that the 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 the 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 proceduresIn 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 to not overfill the refrigerant 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.
- DecommissioningBefore carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its details. 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.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 cylinder conform to the appropriate standards.d) Pump down the refrigerant system, if possible.e) If a vacuum is not possible, make a manifold so that the refrigerant can be removed from various parts of the system.f) Make sure the cylinder is situated on the scales before recovery takes place.g) Start the recovery machine and operate in accordance with the 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 refrigerant system unless it has been cleaned and checked.
- LabelingEquipment shall be labeled stating that is 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.
- RecoveryWhen removing refrigerants from a system, either for servicing or de-commissioning, 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 labeled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with a 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 the 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 with 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.
- Transport of equipment containing flammable refrigerantsCompliance with transport regulations
- Discarded appliances supply flammable refrigerantsSee national regulations
- Storage of equipment/appliancesThe storage of equipment should be in accordance with the manufacturer’s instructions.
- Storage of packed (unsold) equipmentStorage 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.
- Marking equipment using signsSee local regulations.
