Introduction
General Description
Daikin Pathfinder
®
model AWV chillers are complete, self-
contained, automatically controlled, liquid-chilling units
featuring variable speed screw compressors. All model
AWV chillers are equipped with a single evaporator and
microchannel condenser coils along with two compressors.
Pathfinder
®
chillers are designed for outdoor installation only.
The chillers use refrigerant HFC-134a that has no ozone
depletion level.
Only normal field connections such as water piping, electric
power, and control interlocks are required, thereby simplifying
installation and increasing reliability. Necessary equipment
protection and operating controls are included.
All Daikin Applied screw chillers must be commissioned by
a Daikin Applied service technician or an authorized service
provider. Failure to follow this startup procedure can affect the
equipment warranty (see
“Receiving and Handling” on page
7)
.
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.
