NTRODUCTION

This operation manual concerns packaged air-cooled water chillers

of the Daikin EWAQ-DAYN series. These units are provided for

outdoor installation and used for cooling applications. The EWAQ

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.
