Checks to the refrigerating 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 actual REFRIGERANT CHARGE 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;
• refrigerating 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.

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 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 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.
2. Sealed electrical components shall be replaced.

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 must be replaced.

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. The following leak detection methods are deemed acceptable for all refrigerant systems. Electronic leak detectors may be used to detect refrigerant leaks but, in the case of FLAMMABLE REFRIGERANTS, 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 also 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. Removal of refrigerant shall be according to Removal and evacuation.

Removal and evacuation

When breaking into the refrigerant circuit to make repairs -or for any other purpose- conventional procedures shall be used. However, for flammable refrigerants it is important that best practice be followed, since flammability is a consideration.

The following procedure shall be adhered to:

• safely remove refrigerant following local and national regulations;
• purge the circuit with inert gas(optional for A2L);
• evacuate(optional for A2L);
• continuously flush or purge with inert gas when using flame to open circuit ;and
• open the circuit .

The refrigerant charge shall be recovered into the correct recovery cylinders if venting is not allowed by local and national codes. For appliances containing flammable refrigerants, the system shall be purged with oxygen-free nitrogen to render the appliance safe for flammable refrigerants. This process might need to be repeated several times. Compressed air or oxygen shall not be used for purging refrigerant systems. For appliances containing flammable refrigerants, refrigerants purging shall be achieved by breaking the vacuum in the system with oxygen-free nitrogen and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum (optional for A2L). This process shall be repeated until no refrigerant is within the system (optional for A2L). When the final oxygen-free nitrogen charge is used, the system shall be vented down to atmospheric pressure to enable work to take place.

The outlet for the vacuum pump shall not be close to any potential ignition sources, and ventilation shall be 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 in an appropriate position according to the instructions.
• Ensure that the REFRIGERATING 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 REFRIGERATING SYSTEM. Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. 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 recovered refrigerant.

It is essential that electrical power is available before the task is commenced.

1. Become familiar with the equipment and its operation.
2. Isolate system electrically.
3. 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.
4. Pump down refrigerant system, if possible.
5. If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
6. Make sure that cylinder is situated on the scales before recovery takes place.
7. Start the recovery machine and operate in accordance with instructions.
8. Do not overfill cylinders (no more than 80% volume liquid charge).
9. 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.
10. Recovered refrigerant shall not be charged into another REFRIGERATING 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. For appliances containing FLAMMABLE REFRIGERANTS, 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 the flammable refrigerant. If in doubt, the manufacturer should be consulted. 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.

The recovered refrigerant shall be processed according to local legislation 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 compressor body shall not be heated by an open flame or other ignition sources to accelerate this process. When oil is drained from a system, it shall be carried out safely.

Drain Water

1. Drain by Internal Pump

The dehumidifier has an internal pump that helps to drain the condensation water freely.

When using the pump feature:

• The Gravity Drain Outlet needs to be sealed by the included stopper;
• Connect the drain hose to the Pump Drain Outlet;
• Place the unattached end of the hose in a sink, bucket, pump sump, or out of a window anywhere that water can drain out safely. (Ensure there are no kinks or other obstructions that will stop the water to flow.)

NOTE:

• If you use a bucket or other container for water collection, check it regularly to prevent overflows.
• The drain hose for the water pump can drain vertically up to 16ft. More than 16ft may cause water back up to the pump resulting in leakage.
• If the drain hose is too long, water may not drain completely, which can lead to stagnant water and mildew build up inside the hose.
• Before moving the dehumidifier, please remove the stopper from the Gravity Drain Outlet to completely drain the condensation in the internal water tray to avoid water leakage.

2. Drain by Gravity

The collected condensation water can be drained by gravity. When using gravity to drain:

• Connect the drain hose to the Gravity Drain Outlet;
• Place the unattached end of the hose to a suitable drainage facility. The drainage facility should be lower than the drain outlet of the dehumidifier. (Ensure there are no kinks or other obstructions that will stop the water to flow.)

Unplug the power cord before maintaining and cleaning the dehumidifier.

Use a soft damp cloth to clean the body of the dehumidifier. Don't use detergents, scrubbing wires, chemically treated dusting cloths, gasoline, thinner, or other solvents to clean and wipe the machine.

Clean the filter:

There is a washable filter behind the dehumidifier to filter airborne dirt. It is recommended to check the filter regularly and clean it at least once a month.

1. Use a vacuum cleaner or something to gently remove the dirt on the filter;
2. If the filter is particularly dirty, rinse it with warm water and mild detergent, and dry it thoroughly; do not expose the filter to direct sunlight or use other exothermic products to dry the filter, which will deform the filter and its frame;
3. Put the dried filter back into the dehumidifier; If the dehumidifier fails, please follow the "Troubleshooting" in the manual before contacting ANDTE support. Do not repair or disassemble the dehumidifier by yourself.

Improper maintenance may endanger the safety of users.

Note: Don't operate the dehumidifier without a filter because dirt and lint maybe clog it.

Safety Precautions

1. When using, do not place the dehumidifier on soft, uneven ground to avoid vibration or movement. A cartoon shows a dehumidifier on uneven ground with a red 'X' symbol, illustrating the warning against placing it on unstable surfaces.
2. Do not use thin rods or hard objects to insert into the fuselage to avoid malfunction or danger. A cartoon shows a dehumidifier with a red 'X' symbol over inserting thin rods, warning against this action.
3. When using, please keep the dehumidifier away from heat sources such as heaters and electric kettles to save electricity. A cartoon shows a dehumidifier being kept away from heat sources like a radiator and an electric kettle, illustrating the warning to avoid heat sources.
4. When using, please close the doors and windows to achieve the best dehumidification effect. A cartoon shows a dehumidifier with closed curtains or blinds, illustrating the benefit of closing doors and windows for better dehumidification.
5. Do not place items before and after the dehumidifier. If the ventilation is blocked, the dehumidification effect will be affected. A cartoon shows a dehumidifier with items placed around it, blocking airflow, with a red 'X' symbol, illustrating the warning against blocking ventilation.
6. In case of power failure or long-term non-use, please unplug the power cord. A cartoon shows a dehumidifier unplugged from the wall socket, illustrating the instruction to unplug during power failure or long-term non-use.
7. When cleaning the dehumidifier, gently wipe it with a damp cloth, do not directly spray water to clean it. A cartoon shows a dehumidifier being wiped with a damp cloth, with a red 'X' symbol over spraying water directly onto it, illustrating safe cleaning methods.
8. Do not place any objects on the dehumidifier. A cartoon shows a dehumidifier with a red 'X' symbol over placing objects on top of it, illustrating the warning against placing items on the unit.
9. Please clean the filter every two weeks (do not use hot water above 104°F/40°C, alcohol, gasoline, or toluene). A cartoon shows a filter being cleaned, illustrating the maintenance instruction.
10. During continuous drainage, the drainage pipe must be placed horizontally or downwards, and must not be uneven or entangled. A cartoon shows a drainage pipe positioned horizontally or downwards, illustrating correct drainage setup.
11. After the filter is cleaned, please do not place it in direct sunlight to dry it to avoid deformation. A cartoon shows a filter being dried away from direct sunlight, illustrating the warning against using direct sunlight or heat to dry the filter.
