NTRODUCTION
This operation manual concerns condenserless water-cooled water
chillers of the Daikin EWLP-KA 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.
