Main components (See figure 1) Displayed unit = EUWAB12KAZW1. 1
Condenser
The function of the condenser is to change the state of the refrigerant from gaseous to liquid. The heat gained by the gas in the evaporator is discharged through the condenser to the ambient air, and the vapour condenses to liquid. 2
Compressor
The compressor acts as a pump and circulates the refrigerant in the refrigeration circuit. It compresses the refrigerant vapour coming from the evaporator at the pressure at which it can easily be liquefied in the condenser. 3
Refrigerant filter
The filter installed behind the condenser removes small particles from the refrigerant to prevent blockage of the tubes. 4

5
Evaporator
The main function of the evaporator is to take heat from the water that flows through it. This is done by turning the liquid refrigerant, coming from the condenser, into gaseous refrigerant.
Pull down operation area Protect the water circuit against freezing. When the units operate below –5°C and are installed in a rather windy region, a windscreen is required.
Expansion valve
The liquid refrigerant coming from the condenser enters the evaporator via an expansion valve. The expansion valve brings the liquid refrigerant to a pressure at which it can easily be evaporated in the evaporator.
6
Pressure port refrigerant circuit
These ports make it possible to measure refrigerant pressure in the pipes. 7
Charge valve
Allows refrigerant charge in the circuit. 8
Water in/outlet connection
The water inlet and outlet connection allows an easy connection of the unit to the water circuit of the air handling unit or industrial equipment.

Fill valve (only EUWAP, EUWAB)
When water temperature becomes back to normal, the protector resets automatically, but the controller needs to be reset manually.
Air purge valve
Remaining air in the chiller water system will be automatically removed via the air purge valve. 16
U 7/16 flare pressure ports are provided to connect a device for measuring the pump pressure and the evaporator pressure drop. The waterflow can be deducted from these pressures (Refer to "Figures pressure characteristics" on page 8). Water filter
The filter installed in front of the pump removes dirt from the water to prevent damage to the pump or blockage of the evaporator. The water filter should be cleaned on a regular base. 18
Ball valve
A ball valve is installed in front of and behind the water filter to allow filter cleaning without having to drain the water circuit. 19

Low pressure switch
The I/O PCB (A2P) contains a reverse phase protector.
The low pressure switch is installed on the suction pipe of the unit and measures the evaporator pressure (pressure at the inlet of the compressor). When the pressure is too low, the pressure switch is activated. The unit stops.
The reverse phase protector detects if the 3 phases of the power supply are connected correctly. If a phase is not connected or if 2 phases are inverted, the unit can not start up.

Sensor for outlet water temperature
The outlet water temperature sensor measures the temperature of the water at the evaporator outlet. The protection device shuts down the unit when the temperature of the chilled water becomes too low in order to prevent freezing of the water during operation.
Drain valve
The water circuit can be filled with water via this fill valve. 15
Safety valve (only EUWAP, EUWAB)
The safety valve prevents water pressure from exceeding 3 bar. It protects the tank against burst. Activation of this safety has no influence on the operation of the unit.
The drain valve permits complete drainage of the chiller water system during maintenance or in case of shut down. 14
Flow switch
The flow switch measures the flow in the water circuit. In case the flow does not reach the minimum allowed water flow, the unit will be shut down.
Buffer tank (only EUWAB)
The buffer tank reduces the variation in water temperature in the water circuit. This prevents frequent compressor starts and stops. 13
26
Expansion vessel (only EUWAP, EUWAB)
The water in the water circuit expands with rising temperatures. The expansion vessel stabilizes the pressure changes with changing water temperatures by giving free space to the changing water volume. 12
The discharge thermal protector is activated when the temperature of the refrigerant leaving the compressor becomes too high. The unit stops.
Pressure regulating valve
The pressure regulating valve is used to regulate the water flow in the system.
