LG KNSLA181A LGRED Single Zone Multi-Position Air Handler Indoor Unit with 18000 BTU Cooling Capacity and 20000 BTU Heating Capacity in Black

LG continues to demonstrate global leadership in innovation and technology with their advancements in home comfort solutions. The LGRED° Heat ductless heat pump system boasts superior heating performance in extreme cold weather climates. The multi-position air handler unit can be installed with nearly any pre-existing duct work. LG's air handlers are designed to provide powerful heating and cooling for the larger rooms in your home. Capable of managing high air speeds and volumes effortlessly, the air handler is an impressive solution to your home's heating and cooling needs.

Enhanced Connectivity

LG's new R-32 mini split units require a 5-conductor cable (Not Included) instead of the standard 4-conductor, improving communication reliability and enabling a new leak detection feature.

Quiet Design

The unit can operate at volumes as low as 29 dB thanks to its advanced fan motor. The brushless direct current motor reduces electrical and mechanical sound while providing powerful air movement.

Automated Operation

Auto operation mode continually compares your zone's current and desired temperatures and uses that data to intelligently adjust the unit's fan speed and refrigerant flow to provide optimal comfort.

Sleep Mode

With the Sleep Mode and Timer functions, you can set this indoor unit to save energy at night. Sleep Mode will incrementally adjust temperature for an hour before the Timer function automatically deactivates the unit.

Dehumidify

LG's indoor units include a dehumidifying operation mode. In this mode, the unit's internal sensors monitor temperature and modify the set point and fan speed to remove moisture from the air.

Hot-Start

When the Hot-Start function is enabled, the unit's fan will not engage until the outdoor condenser has had the opportunity to warm the indoor coil. This prevents the unit from blowing cold air during heating operations.

Multi-Position

The air handler can be installed in either a vertical or a horizontal orientation, making it a versatile solution for all manners of duct systems.

Frequently Asked Questions

Q: How often should I change the air filter?

A: Inspect the air filter regularly and replace it at least every 90 days. If you have pets or allergies, more frequent changes may be necessary. A clogged filter can restrict airflow and potentially damage the unit.

Q: How do I maintain the condensate drain line?

A: Regularly check and clear the condensate drain line and drain pan to prevent clogs and water damage. You can flush the drain line with water and use pan tablets to keep it clear.

Q: Should I schedule p​rofessional servicing?

A: Yes, an annual professional inspection is recommended to check electrical connections, refrigerant levels, and fan performance to ensure your system runs efficiently.

Q: What causes low or no airflow from the unit?

A: Low airflow is often due to a dirty air filter but can also indicate a faulty blower motor, a bad capacitor, or a frozen evaporator coil.

Q: What should I do if my unit won’t turn on?

A: First, check if the circuit breaker has tripped. If the breaker is fine, the issue may be a faulty control board or blower motor requiring professional diagnosis.

Q: What do error codes mean on my unit?

A: Error codes indicate specific issues. For example, a CH05 error signals a communication problem between the indoor and outdoor units. Consult the owner’s manual or LG’s support website for details on specific codes.

Q: Why is there ice on my unit?

A: Ice buildup on the evaporator coil can result from a dirty air filter, low refrigerant levels, or restricted airflow. Turn off the system and allow it to thaw before investigating or calling for service.

Q: What do unusual noises from the unit indicate?

A: Excessive vibrations or strange noises may point to problems with the fan, motor, or other internal components. If noises persist, have a professional inspect the unit.
