Alen A375 - Air Purifier Manual

USING YOUR AIR PURIFIER

Operating Your Unit

1. Plug your air purifier into a grounded outlet.
2. Press ON/OFF to start the air purifier. When your unit is on, the control panel screen will light up. To stop the air purifier, press ON/OFF and the indicator light will turn off.
3. Press SPEED and watch the indicator numbers until desired fan speed is achieved.

4. Press TIMER to have the air purifier automatically turn off in a set amount of hours. Up to eight hours.
5. Press IONIZER to activate the ozone-safe ionizer. The built-in IONIZER charges particles in the air. This causes the particles to stick together and become larger, making it easier for the filter and cleaners to trap. Press IONIZER again to turn off.
6. Filter replacement indicator — Light bar will progressively illuminate as filter collects particles. There are two green, two yellow, and one red bar. Each bar represents approximately one month of continuous operation. Once all five bars are fully illuminated (red being the last), it is time to change the filter.
7. After changing the filter, RESET the filter indicator by holding down TIMER while the unit is ON until the clean indicator light disappears.
8. Press UV to activate the built-in ultraviolet lights. Press UV again to turn off.
9. When on AUTO fan speed, the unit will adjust fan speed based on the level of dust or smell. Dust and smell bars adjust horizontally as their respective levels change.

KNOW YOUR AIR PURIFIER

When using the air purifier for the first time in a room, many prefer to use a higher fan speed like speed three or four for a couple of hours in order to clean the room's air initially. Then, it is recommended that the air purifier is left on to run continuously.

CARE & MAINTENANCE

Replacing The Filter

The filters used in all of Alen Air Purifiers are not designed to be washed, cleaned, or otherwise reused. Over time, the filters become overloaded with particles, decreasing their filtration performance. We recommend regular filter replacements (at least every 6 months with normal use) to extend the life of your air purifier and maximize performance.

The black foam layer of the filter, known as the pre-filter, captures large dust and hair. This layer is held on with Velcro^®-like strips.. Once removed, the Alen pre-filter can be washed or vacuumed to maintain efficient operation of the unit.

For optimal performance, it is recommended that the air purifier is left on to run continuously. Under this type of usage, filters will need to be replaced approximately every six months.

Why You Should Replace Your Filter

• You purchased an Alen Air Purifier to improve the quality of your indoor air.
• Changing your filters on time is the only way to maintain an optimal level of air quality.

How To Replace The Filter

1. Always unplug the unit when installing a filter.
2. Distinguish the front side from the back side of the filter.
3. It is recommended to wear gloves while discarding the used filter. Place the used filter in a plastic bag to prevent dust from reentering the air.

1. With the front of the unit facing up, pull up on the lower left or right corner of the front inlet air intake grill.
2. After pulling up, push the grill towards the display panel at the top of the unit.
   

3. Remove the used filter by lifting the pull string.
   

4. Take the new filter out of the plastic bag and insert it into the air cleaner with the arrow pointing inward.
5. Insert the top of the inlet grill first and then snap in the lower part of the grill.
   

6. RESET the filter indicator by holding down TIMER while the unit is ON until the clean indicator light disappears.
   

How To Replace The UV Light

1. Before replacing the UV light, please unplug the unit.
2. With the front of the unit facing up, pull up the lower end of the inlet grill and push it toward the display panel at the top of the unit, then remove it.
3. Remove the filter by lifting the pull string.
4. Unscrew the screws on the lampshade with a screwdriver, and then remove the lampshade.
5. Gently rotate the bulb a quarter turn in either direction until it unlocks from the socket. Pull the pins out of the sides of the socket, one end at a time.
6. Unpack the new UV bulb gently by handling the ends only. Starting with one end of the bulb, then the other, gently insert the metal pins on the bulb into the white slotted socket one pin at a time. Once the ends of the bulb are completely inserted into the socket, rotate the bulb a quarter turn until it locks into place.

TROUBLESHOOTING TIPS

How do I reset the filter indicator light? I put in a new filter but the light is still illuminated.
After changing the filter, RESET the filter indicator by holding down TIMER while the unit is ON until the illuminated clean indicator light disappears.

Can I clean the filter?
The black mesh layer on the front of the filter, known as the Pre-filter, captures large dust and hair. This layer is held on with Velcro^®-like strips. This Pre-filter can be vacuumed in place to maintain efficient operation of the unit. No other layers or parts of the filter can be washed, cleaned, or otherwise reused. Please replace the filter regularly to maintain optimal performance.

How can I tell if my UV lights have burnt out?

Turn on the UV lights by pressing UV and set the fan speed to 1. Make sure the room that the unit is placed in is dark. Look through the top of the unit where the air blows out to see if there is a blue glow. This glow is quite faint, so you may need to press the UV button on/off several times to see if you notice a difference. If there is no glow, then the UV lights have burnt out and need to be replaced. Visit www.alen.com or call 1-800-630-2396 to order a replacement UV light. UV lights are like normal light bulbs and will last approximately 9 to 12 months when operated continuously.
