Is my Fan Blade Working Efficiently in my New Air Purifier?

The following are guidelines to tighten your fan blade for the following new air purifier models: LA-2000 to Classic LA-3500 (Model #: E300/RH02; 300/RH02; 300/H02; 300/UH02; HL2PRO; ZL-3500/UV)

 

Do you think the performance of your unit is being effected by a faulty fan blade? Before you secure your loose fan blade, dismantling your unit is mandatory. It shouldn’t take longer than about 15 minutes as it’s quite easy to remove the chassis from the cabinet. First, unscrew the two knobs on the front side of the unit. This would be the 03/Sanitizer and Fan/UV left and rights knobs which both have a small screw attaching them to the unit. Locate the tiny circular opening within each of the knobs to access the screws and unscrew each.

Now, on a hard surface, place the unit upside down and unscrew the bottom two bolts. Then, flip the unit back to its upright position (and on a hard surface still), and you should have easy access to the chassis (mechanism) of the unit. Remove it. Once you’ve moved the chassis, remove the metal protection bar by unscrewing and disconnecting it. Now, you should have easy access to the fan blade!

The blade should be positioned in the middle of the fan motor shaft itself, which is almost half way from the fan motor body and shaft. It shouldn’t be too close to the fan motor body nor in the very front of the fan motor shaft because it may risk touching the two metal prongs of the negative ionizer. Again, it should be placed in the middle of the fan motor shaft, which is an inch away from each end of the fan motor. Fasten the metal clamp of the fan blade by using pliers carefully. Do not maneuver the fan blade drastically and try to keep the fan blade on at all times when securing it. The metal clamp should be right in the middle of the fan blade over its opening (through which the fan motor shaft fits).

Now, reassemble the metal bar in front of the fan blade (and, if applicable, screw in the green ground wire connecting to the metal bar). Place the chassis mechanism fully back into the cabinet and reassemble the unit by following the instructions in reverse (secure the top, then bottom surfaces). Now, plug in your unit and turn it on as you monitor it the next couple of days. Please visit alpineairtechnologies.com if you have further questions!
