General Description
Daikin Applied Centrifugal Water Chillers are complete, self-
contained, automatically controlled fluid chilling units. Each unit
is completely assembled and factory tested before shipment.
The WDC series is equipped with two compressors operating
in parallel on a single evaporator and condenser. The WCC
series is equipped with two compressors, each operating
on one refrigerant circuit of a two circuit evaporator and
condenser. In the series, each unit has one compressor
connected to a condenser and evaporator. The basic sizes of
compressors are the 079, 087, 100, 113,and 126. They provide
a cooling capacity range from 600 to 2700 tons. The chillers
use R-134a or R-513A refrigerant.
The controls are pre-wired, adjusted and tested. Only normal
field connections such as piping, electrical and interlocks, etc.
are required, thereby simplifying installation and increasing
reliability. Most necessary equipment protection and operating
controls are factory installed in the control panel.
All Daikin Applied centrifugal chillers are factory tested prior to
shipment and must be initially started at the job site by a
factory trained Daikin Applied service technician. Failure to
follow this startup procedure can affect the equipment warranty.
The standard limited warranty on this equipment covers parts
that prove defective in material or workmanship. Specific
details of this warranty can be found in the warranty statement
furnished with the equipment.
