MULTI-POSITION AIR HANDLER UNIT
AHU 18K, 24K, 30K, 36K, 48K, 60K Btu/h
INTELLIGENT AIR FLOW: Three speed fan motor so that static air pressure can be adjusted automatically or manually.
ANTI-COLD AIR FUNCTION: Fan doesn't blow until the coil is warm to prevent pushing cold air into the room upon startup.
TU1 COPPER TUBES: Oxygen-free copper with higher purity copper content of over 99.97%, providing excellent electrical and thermal conductivity and superior corrosion and cold resistance.
FAST COOL/HEAT FUNCTION: When set temperature is more than 10 degrees difference from room temperature, the unit will run at 100% capacity to reach its set temperature faster.
ALUMINUM COIL: Fewer corrosion points than copper coils.
AUXILIARY HEATER: Purchased separately as a backup heat option for indoor units, available in 5kW, 10kW, 15kW, and 20kW models.
AUTO RESTART FUNCTION: Restarts automatically in the event of a power outage.
REFRIGERANT LEAK DETECTION: Protects the compressor from damage due to refrigerant leak by alerting user with error code "EC".
WIRED CONTROLLER: Compatible with most 24V wired thermostats.
TRUE MULTI-POSITION AIR HANDLER: Can be installed in Horizontal or Vertical upward and downward positions for optimal space usage.

CONTROL OPTIONS
· 12V Wall Thermostat · Remote control Included · Downloadable C&H app

Refrigerant Sensor

OUTDOOR CONDENSERS
INVERTER TECHNOLOGY: Promotes energy efficiency by keeping the motor running to create a gentle on/off process.
GOLD FIN: Gold coating on the condenser withstands the salty air, rain and other corrosive elements, to prevent bacteria growth.
DRAIN PAN HEATER: Factory installed drain pan heater in outdoor unit prevents ice accumulation, improving heat transfer efficiency.
ELECTRONIC EXPANSION VALVE: Helps to manage the refrigerant flow.
HIGH-FREQUENCY RACER TECHNOLOGY: Enables the compressor to reach maximum speed within 6 seconds on start up.
INTELLIGENT DUSTING SWITCH: Reverses the fan to clean dust, sand, and other debris from the coil.

Wall Thermostat should be connected to the unit to be Smart
