a. Metallic protective cabinet with rustproof polyester paint;
b. Built-in with voltage protection, current protection, anti-freezing protection, water flow protection and
etc., effectively guarantee the system to work safely.
2.7 User friendly remote control
Switch SW4_1(10kW) or SW3_1(12-16kW) on the PCB to ON to enable the following remote control
functions. The setting is not default at factory.
Remote shut down
Remote cooling and heating
Note: When all controller controls together, the unit will work according to the last order.
5/7kW will be available soon.
2.8 Flexible and convenient control
Built-in electronic controller at factory.
Compact devices with advanced function and friendly user interface.
The chiller can be controlled by wired controller (KJR-120F/BMK-E)
also which is optional chosen.
Note: When connecting wired controller, outdoor unit control panel is mainly used for display which can
check parameters and inquiry, and can’t be used to set mode and temperature.
Built-in water pressure gauge. Inspect the water pressure all the time.
2.9 Integrated and compact design
Fully integrated and built-in hydraulic module, such as expansion tank, plate type of heat exchanger,
water circulating pump, etc. It saves installation space and cost.
2.10 EXV control flow more precisely
Patented liquid distribution components to maximize performance and minimize defrost impact.
Stable and accurate gas flow control. EXV achieves 500 pulses to adjust flow precisely. Ensure the
temperature-control precisely and steadily to provide a comfortable environment.

3. 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.
Condenser coils:
The coils are made from high performance and seamless copper tuber and high surface area aluminum fins
to ensure optimum heat exchange capability.Condenser coil protection grill is standard.
Fan motor:
To achieve high efficiency heat exchange, the unit is equipment with the high performance axial-flow 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.
Evaporator:
The heat exchanger is made of AISI 316 stainless steel to ensure high heat exchange efficiency, complete
with electric heater and differential pressure switch. The complete heat exchanger is insulated with thermal
insulation closed cell rubber foam to give optimum thermal insulation.
Hydraulic module:
It is fully integrated and equipped with key hydraulic components such as expansion tank, plate type of
heat-exchanger, 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.
