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.
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
start-up" on page 7.
