NTRODUCTION
This operation manual concerns packaged air-cooled water chillers
of the Daikin EWYQ-DAYN series. These units are provided for
outdoor installation and used for cooling and heating applications.
The EWYQ 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.

READ THIS MANUAL ATTENTIVELY BEFORE STARTING
UP THE UNIT. DO NOT THROW IT AWAY. KEEP IT IN
YOUR FILES FOR FUTURE REFERENCE.
Before starting up the unit for the first time, make sure that
it has been properly installed. It is therefore necessary to
carefully read the installation manual supplied with the unit
and the recommendations listed in "Checks before initial
start-up" on page 7.

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 refri-
gerant 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.
■Condenser (in cooling mode) or evaporator (in heating mode)
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.
■Liquid receiver
The liquid receiver prevents the plate heat exchanger from
flooding with liquid in heating mode caused by a great difference
between the volumes of coil and plate heat exchanger.
■Filter/drier
The filter installed behind the condenser removes small particles
from the refrigerant to prevent damage to the compressor and
expansion valve.
The drier takes the water out of the system.
■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.
