INTRODUCTION
This operation manual concerns condensorless water-cooled water
chillers of the Daikin EWLP-KB series. These units are provided for
indoor installation and used for cooling applications. The EWLP units
can be combined with Daikin fan coil units or air handling units for air
conditioning purposes. They can also be used for supplying water for
process cooling.
This manual has been prepared to ensure adequate operation and
maintenance of the unit. It will tell you how to use the unit properly
and will provide help if problems occur. The unit is equipped with
safety devices, but they will not necessarily prevent all problems
caused by improper operation or inadequate maintenance.
In case of persisting problems contact your local Daikin dealer.

Function of the main components
Figure: Functional diagram
As the refrigerant circulates through the unit, changes in its state or
condition occur. These changes are caused by the following main
components:
■Compressor
The compressor (M*C) acts as a pump and circulates the
refrigerant in the refrigeration circuit. It compresses the
refrigerant vapour coming from the evaporator to a pressure at
which it can easily be liquified in the condenser.
■Filter
The filter installed behind the condenser removes small particles
from the refrigerant to prevent blockage of the tubes.
■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.
■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.
■Water in/outlet connections
The water inlet and outlet connection allow an easy connection
of the unit to the water circuit of the air handling unit or industrial
equipment.
Safety devices
The unit is equipped with General safety devices: shut down all
circuits and stop the whole unit.
■I/O PCB (A2P) (input/output)
The I/O PCB (A2P) contains a reverse phase protector.
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.
■Overcurrent relay
The overcurrent relay (K*S) is located in the switch box of the
unit and protects the compressor motor in case of overload,
phase failure or too low voltage. The relay is factory-set and may
not be adjusted. When activated, the overcurrent relay has to be
reset in the switch box and the controller needs to be reset
manually.
■High-pressure switch
The high-pressure switch (S*HP) is installed on the discharge
pipe of the unit and measures the condenser pressure (pressure
at the outlet of the compressor). When the pressure is too high,
the pressure switch is activated and the circuit stops.
When activated, it resets automatically, but the controller needs
to be reset manually.
