IM 1029-2 Magnitude™ Frictionless Centrifugal Chillers – Model WMC 3

Introduction

General Description

The Daikin Magnitude™ Frictionless Centrifugal Chillers are complete, self-contained, automatically

controlled, fluid-chilling units featuring oil-free, magnetic bearing compressors. Each unit is completely

assembled and factory tested before shipment.

ey are designed for indoor, non-freezing installation only.

Magnitude chillers are equipped with two compressors operating in parallel with a single evaporator and

single condenser. The model WMC 145S has a single compressor.

The chillers use refrigerant R-134a that operates at a positive pressure over the entire operation range, so no

purge system is required.

The controls are pre-wired, adjusted and tested. Only normal field connections such as water piping, relief

valve piping, electric power and control interlocks are required, thereby simplifying installation and

increasing reliability. Necessary equipment protection and operating controls are included.

All Daikin centrifugal chillers are factory-tested prior to shipment and must be commissioned by a factory-

trained Daikin 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.
