2. Prior to beginning work on systems containing FLAMMABLE REFRIGERANTS, safety checks are necessary to ensure that the risk of ignition is minimized.
3. Work shall be undertaken under a controlled procedure so as to minimize the risk of a flammable gas or vapor being present while the work is being performed.
4. 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.
5. The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is with all applicable refrigerants, i. e. non sparking, adequately sealed or intrinsically safe.
6. If any hot work is to be conducted on the refrigerating 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.
7. No person carrying out work in relation to a REFRIGERATING SYSTEM which involves exposing any pipe work 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 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.

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 the apparatus is mounted securely. Ensure that seals or sealing materials have not degraded to the point 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.
12. 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.
13. 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.
14. Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.
15. 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.

Cautions

The dehumidifier must be used on a level and stable surface. ⚠️

To prevent the water from freezing, do not use the dehumidifier and the drain hose at ambient temperature below 32°F (0°C). ?

Do not use the dehumidifier outside. Exposure to direct sunlight or rain may result in overheating, electric shock and fire. ?

Operation and Efficiency

Defrosting Operation

The evaporator in the dehumidifier may defrost automatically if it is operated in the room temperature less than 32°F. The defrosting device may start up and operate for some time (about 5 minutes) automatically every 25 minutes or even longer.

During the defrosting operation, the dehumidification function and air purification function may intermit.

Please don't turn off the switch or pull out the power plug of the dehumidifier during the defrosting operation. ?

The room temperature increases during the operation.

This dehumidifier doesn't have cooling function. It will produce heat during the operation and increase the room temperature 2-7 °F (1-4°C). This temperature rise may be very distinct in the cabinet or other similar spaces. In addition, the door and windows are closed and other appliances in the room can give out heat as well as the radiation of the sun can raise the room temperature.

Dehumidifying Capacity

The illustration below shows the daily dehumidifying capacity of the dehumidifier. This capacity is based on the 86 °F of room temperature, the dehumidifier sets 80% of relative humidity and the data when the air outlet is fully open. At different temperatures and relative humidity, it may have different dehumidifying capacities.

In the same room temperature, the dehumidifying capacity is higher in higher relative humidity and the dehumidifying capacity is lower in lower relative humidity. In the same relative humidity, the dehumidifying capacity is higher in higher temperature and the dehumidifying capacity is lower in lower temperature.

If the dehumidifier is placed in the cabinet, its dehumidifying capacity may highly reduce in a short period after operating, that is, the humidity in the cabinet has been highly reduced.
