The 40MUAA Air Handler is a fan coil unit designed to provide quiet and maximum comfort in indoor environments. It is available in sizes ranging from 18K to 60K. When matched with an outdoor condensing unit, the air handler not only offers cooling and/or heating but also filters and dehumidifies the air, contributing to a more comfortable indoor atmosphere.
The Air Handler operates in several modes to suit different comfort needs:
The Air Handler can be controlled using either a wireless remote control or a wired controller, both of which are provided with the unit.
Auto Start Function: In the event of a power failure while the unit is operating, the Air Handler stores its current operating conditions. Once power is restored, the unit automatically resumes operation under those previously stored conditions, ensuring continuous comfort without manual intervention.
Energy Saving Recommendations: To enhance the efficiency of the ductless system, several practices are recommended:
Regular care and maintenance are crucial for the optimal performance and longevity of your Air Handler.
Maintenance – Long Periods of Non-Use: If you plan not to use the air conditioner for an extended period, follow these steps:
Maintenance – Pre-Season Inspection: After long periods of non-use, or before periods of frequent use, perform the following:
Outdoor Unit Maintenance: Any maintenance and cleaning of the outdoor unit should be performed by an authorized dealer or a licensed service provider. Similarly, any unit repairs must be carried out by authorized personnel. Improper repair and maintenance can lead to water leakage, electrical shock, fire, and may void your warranty.
Fuse Replacement: Do not substitute a blown fuse with a higher or lower amperage rating fuse, as this can cause circuit damage or an electrical fire.
Drain Hose and Wiring: Ensure the drain hose is set up correctly to prevent leakage, property damage, fire, and electric shock. All wires must be connected properly to avoid electrical shock or fire.
Troubleshooting: In case of issues, refer to the troubleshooting section in the manual before contacting a service company. If a problem persists, contact a local dealer or customer service center, providing a detailed description of the malfunction and the unit's model number.
