Beurer LR 310 - Air Purifier Manual

Getting to know your device

Humans spend a large proportion of their time indoors. The air indoors is often polluted with dust particles, pollen, animal hair, odours, harmful gases as well as various bacteria and viruses. The LR 310 air purifier cleans the ambient air using a three-layered filter system and an in-built UV-C light.
The LR 310 air purifier

• Filters air with a combi filter (activated carbon filter against harmful gases and unpleasant odours, HEPA filter H 13 against particles such as bacteria, viruses, mites, pollen and fine dust)
• Has an in-built UV-C light (to kill germs)
• Operates quietly with three output levels
• Has a timer function (two, four or eight hours)
• Has a fine dust particle sensor
• Is suitable for rooms up to 54 m² (according to NRCC-54013-2011)
• Energy-saving
• Switches off automatically when the housing cover is removed.

Principle of air cleaning

1. The air purifier's fan sucks in the contaminated air.
2. The pre-filter filters larger particles such as dust, dirt and hairs.
3. Next, the activated carbon filter filters formaldehyde, benzene and other poisonous gases and odours out of the ambient air.
4. Lastly, the HEPA filter filters out small particles such as pollen, bacteria or viruses.
5. The switchable UV-C light inside the housing eliminates germs and odours (caused by animals, cooking or tobacco smoke).
6. The cleaned air is emitted into the ambient air via the air outlet on top of the air purifier.

The HEPA H 13 filter has a filter performance of ≥ 99.95%. That means that 99.95% of particles (e.g. bacteria, viruses and fine dust) can be filtered out.

Contaminated, unfiltered air can have the following effects:

• Infections and respiratory diseases are more likely to occur
• Damage to health through harmful gases

Initial use

Removing the air purifier

1. Open the cardboard packaging.
2. Remove the device from the top of the box without opening the film bag.
3. Now remove all plastic films. Remove the combi filter from the device (see "Filter change" section) and take it out of the plastic film. Then re-insert the combi filter into the device.

3. Press the ON/OFF button () to switch on the air purifier.

Note
When the air purifier is used for the first time it is set to the middle fan speed.

Automatic function

The air purifier has an automatic function. When the automatic function is switched on, the fan speed automatically adapts to the ambient air quality. This means that, the poorer the quality of the ambient air, the higher the fan speed automatically set by the air purifier.

1. To switch on the automatic function, press the AUTO button while the air purifier is switched on (). As soon as the automatic function is active, a light goes on above the AUTO button.
2. Press the AUTO button () again to switch off the automatic function. The light above the AUTO button goes out.

• To switch between the individual fan speeds, press the fan speed button . The fan speed that is currently set lights up on the control panel.

UV-C light

The UV-C light eliminates germs contained in the air. Here the UV-C light activates titanium oxides that break down the foul-smelling odour molecules (caused by tobacco smoke, cooking smells or animals).

1. To switch on the UV-C light, press the UV-C button on the air purifier while it is switched on (). As soon as the UV-C light is active, a light goes on above the UV-C button.
2. Press the UV-C button () again to switch off the UV-C light. The light above the UV-C button goes out.

Timer function

The air purifier features a timer function that you can use to determine the number of hours the air purifier should run for before it automatically switches itself off. The air purifier has three timer periods: 2H (two hours), 4H (four hours) and 8H (eight hours).

• To switch between the individual timer periods, press the TIMER button () The TIMER period that is currently set lights up on the control panel. The air purifier will now automatically switch off after the set number of hours has passed.
• To switch off the timer, repeatedly press the TIMER button (), until the light above the TIMER button goes out. The air purifier now cleans continuously.

Filter change

The three-layered filter should be replaced with a new one after 4320 operating hours. After 4320 operating hours, a blue LED flashes above the AUTO button. To change the filter, proceed as follows:

1. Press the ON/OFF button to switch off the air purifier, and unplug it from the socket.
   
2. Remove the housing cover as shown (magnetic fastening). Firstly detach the magnetic fastening at the bottom, and then at the top.
   
3. Pull out the pre-filter. Now, to pull out the combi filter, pull carefully on the side tabs.
   
4. Insert a new combi filter. To insert the combi filter correctly, align it with the side tabs as shown. Position the pre-filter above it.
   
5. Re-insert the housing cover as shown until you see and hear it click into place (magnetic fastening). First attach the magnetic fastening at the top, and then at the bottom.
   
6. Insert the mains plug into the socket. Ensure that the cable does not pose a trip hazard. Press and hold the AUTO button () for five seconds. The operating hours counter now resets to 0.
   

If you wish to change the combi filter at specific personal intervals (e.g. every six months), there is a sticker on the upper edge of the combi filter on which a date can be entered.

Cleaning and maintenance

Before cleaning, always ensure that the mains plug of the air purifier has been properly disconnected.

Cleaning the filter

Regular cleaning of the filter (once a month) is a prerequisite for hygienic and fault-free operation.

• Clean the three-layered filter using the brush attachment of a vacuum cleaner. To carry out a thorough clean, pull out the pre-filter and clean the activated carbon filter located behind it and the HEPA filter located at the rear, also using the brush attachment from a vacuum cleaner. Then replace the pre-filter on the HEPA filter.
  

The three-layered filter should be changed after 4320 operating hours (see "Filter change" section).
The three-layered filter cannot be washed.

Cleaning the fine dust particle sensor

The fine dust particle sensor should be cleaned every 2 months.

Note
If the air purifier is used in a dusty environment, it may need to be cleaned more often.

To clean the sensor, switch off the air purifier and pull the mains plug out of the socket. Open the cover on the side of the housing, and remove the cover.

Clean the sensor, along with the air inlet and outlet using a moistened cotton bud.

Afterwards, dry all of the cleaned parts using a dry cotton bud.
Attach the fine dust particle sensor cover again.

Cleaning the housing

Clean the housing of the air purifier with a damp cloth (water or a mild cleaning solution). When cleaning, do not use any solvents or other aggressive or abrasive cleaning agents, as the surface may become damaged.

Storage

If you do not plan to use the device for a long period of time, we recommend that you clean it and store it in the original packaging in a dry environment, ensuring it is not weighed down by additional items.
