Pathfinder aws-b series air cooled chillers (rev 0b) standard, high, & premium efficiencies includes models with vfd and models with remote evaporator 170 to 550 tons, 600 to 1930 kw, r-134a, 60hz
Design Vintage T = Triple Compressor General Description Daikin McQuay Pathfinder™ air-cooled chillers are complete, Information on the operation of the unit MicroTech self-contained chillers that include the latest in engineered controller is in the OM 1123 manual, available on components arranged to provide a compact and efficient unit.
Installation and Startup Installation and maintenance are to be performed only by For pad-mounted units, it is recommended that the unit be Installation and Startup qualified personnel who are familiar with local codes and raised a few inches with suitable supports such as neoprene waffle vibration pads, located at least under the mounting regulations, and experienced with this type of equipment.
Installation and Startup The right-hand panel contains a circuit breaker. A minimum of Single Point Disconnect Switch four feet of clearance is required in front of the panels. The side clearance required for airflow provides sufficient service clearance. Compressor #2 On all Pathfinder units, the condenser fans and motors can be Compressor #1 Circuit Breaker...

Installation and Startup Chilled Water Piping employed in lieu of ethylene glycol, the added pressure drop and loss of performance could be substantial. IMPORTANT: Piping design must be provided by a Do not use PVC or CPVC piping due to incompatibility qualified Architect or Systems HVAC Design Engineer with POE oil in the event of a refrigerant to water leak.

Figure 12: Strainer Pressure Drop Variable water flow involves reducing the water flow through the evaporator as the load decreases. Daikin McQuay chillers are designed for this duty, provided that the rate of change in water flow is slow, and the minimum and maximum flow rates for the evaporator are not exceeded.
Installation and Startup will result in decreased capacity and increased pressure Flow Switch drop. Note: Do not use automotive grade antifreezes as A flow switch must be included in the chilled water system to they contain inhibitors harmful to chilled water systems. prove that there is adequate water flow before the unit can Use only glycols specifically designated for use in start.
AWS chiller units are designed to operate with leaving chilled fluid temperatures of 20.0°F to 60.0°F (-6.7°C to 15.6°C). each unit is shown in the Physical Data Tables beginning on Consult the local Daikin McQuay sales office for performance page outside these temperatures.
