Is there an air filter for this unit? I have this unit in my apartment and I have a problem with dust in the apartment I checked and the air conditioner does not have the filter.

Asked by: Holamanuel1
The LG 10,000 BTU Thru-the-Wall Air Conditioner with remote, Model # LT103HNR comes with a removable, washable air filter that is located behind the inlet grille in the front of the unit. You need to pull the inlet grille forwards to get to the air filter. The replacement air filter, Part # 5230A20007A can be purchased from any of our Regional LG Authorized Parts Distributors located in the Western, Central and Eastern regions of the U.S. The closest one to your location is: Andrews Electronics 25158 Avenue Stanford Santa Clarita, CA 91355 Sales : 877-389-6384 Fax : 800-289-0301^IFV

circuit breaker amps when 2 units are wired in series

Asked by: hunk
The installation instructions, for this unit, recommend the use of a dedicated circuit for the air conditioner. Connecting the unit “in series” with another unit is improper installation and as such, we cannot recommend this type of connection.

provide me with an exterior view

In addition to what the exterior view should look like (I had one installed and I believe the guy left off and exterior trim piece) I would like to know how you secure the unit so it can't be pushed back inside the room. Thanks.
