3.9 Water pump starts/stops compulsory function
Full DC inverter mini Heat pump adopts highly intelligent inverter-driven compressor. This advanced technology
enables the output of the outdoor unit to be modulated by the real heat load demands..
This advanced system ensures precise temperature regulation and highly efcient energy usage, making a
signicant contribution to limiting the impact on the environment.
Optimally design fan shape and new designed discharge air grille and air deector, making higher air volume and
lower operation sound.
Stable and safe running in wide ambient temperature range, cooling performance from 10 ˚C to 46˚C, heating from
-20˚C to 35˚C.
By adopting high efciency Coaxial heat exchanger or tubes in shell heater exchanger, the energy consumption can
be reduced.
Compact devices with advanced function and friendly user interface.
The Heat pump can be controlled by optional wired controller (YR-E27) ,
Fully integrated and built-in hydraulic module, such as Coaxial heat exchanger or tubes in shell heater exchanger,
water circulating pump, the water pressure difference switch, etc. It saves installation space and cost.
Stable and accurate gas ow control. EXV achieves 500 pulses to adjust ow precisely. Ensure the temperature-
control precisely and steadily to provide a comfortable environment.
Fast respond resulting in higher efciency and improved reliability.
Press the key “Set” of YR-E27 for 15 seconds to start the water pump operating when the unit is standby. Press “Set”
key for 15 seconds again to stop the water pump.
Built-in with voltage protection, current protection, anti-freezing protection, water ow protection and etc., effectively
guarantee the system to work safely.
Hydrophilic lm ns and inner-threaded copper pipes optimize heat exchange efciency.

4. Description Of Main Components
Structure
Panels and base are made from galvanized steel plate painted with epoxy power to ensure total resistance to
atmospheric pollution, condensate collection pan as standard.
Air cooled coils:
The coils are made from high performance and seamless copper tuber and high surface area aluminum ns to
ensure optimum heat exchange capability. Condenser coil protection grill is standard.
Fan motor:
To achieve high efciency heat exchange, the unit is equipment with the high performance axial-ow fans. The fan
is driven directly by weather proof motor to ensure reliable operation, the fan motor is six-pole electric motor with
built-in thermal cut-out.
Hydraulic module:
It is fully integrated and equipped with key hydraulic components such as Coaxial heat exchanger (applied for
AU082) and tubes in shell heater exchanger (applied for AU112/162). water circulating pump.The water pressure
difference switch is provided in the units to protect against damage to the water pump.
Power and control electrical panel
Power and control electrical panel constructed in accordance with IEC 204-1/EN60335-2-40, complete with
compressor contactor,control via control panel.
