Ducane 9,000 BTU Wall Mounted Heat Pump Ductless Mini-Split System - 18 SEER

Wall Mounted Indoor Unit:

Low-sound, three-speed Wall Mount with LED display offers
three access points for refrigerant outlet pipes: left, right
or rear. The front panel can be raised for accessible wiring
and maintenance. Swing louver angles to 90°. Unit installs
horizontally on a vertical wall.

• Pre-Heat Function - Delays the operation of the fan until the indoor coil has reached a pre-determined temperature which prevents the discharge of cold air while the system is operating in the “heating” mode.
• LED Readout - Mounted on unit. LED displays unit operation status, and codes for maintenance and servicing.
• Auto Restart - Automatically restores the previous function setting if power is interrupted.
• Cooling Override - Button on the indoor unit allows a temporary 30 minute override of the system for forced “AUTO” or “COOLING” operation.
• Flare Connections - Equipped with liquid and gas flare fittings for quick and secure piping.
• Multi-Refrigerant Outlet - Allows left, right, or rear access for refrigeration line connection.
• Three Speed Fan - Fan functions at three speeds: low, medium and high.
• Air Filter - Cleanable air filter is furnished as standard.

Outdoor Heat Pump Unit:

COMPRESSOR 

• Variable Frequency Rotary 
• Compressor Compressor features high efficiency operation. Balanced for reduced vibration and quiet operation. 
• Brushless DC motor uses powerful Neodymium magnets, which are approximately 15-20 times stronger than ferrite magnets used in conventional AC compressors. 

Compressor Crankcase Heater 

• Protects against liquid refrigerant migration that can occur during low ambient operation. 

CONTROLS 

DC Inverter Control 

• Provides continuous operation, while adjusting capacity according to room temperature. 
• The accurate sensing of cooling loads prevents frequent changes in capacity and ensures efficient, economical operation. 

Inverter Module Protection 

• Protects against differences in current, voltage and temperature. Displays code on the indoor unit indicating a need for servicing. Outdoor Unit Microprocessor 
• Electronic expansion valve control. 
• Automatic compressor timed-off protection (3 minutes). Temperature sensor. 
• LEDs on control display error codes and assist in troubleshooting. 4-Way reversing valve control. 

Capillary Tube Refrigerant Metering
