LOCATIONS AND RECOMMENDATIONS

These units are designed for outdoor installation. For proper instal- lation, the following recommendations must be considered.

NOTE: Unit shipped for horizontal installation. Convert to downflow per instruction.

The discharge air from the condenser fans must be unrestricted for a minimum of 3 feet above the unit.

Roof Mounting Curb (field assembled BAYCURB030A and BAYCURB033A, BAYCURB034A) or a field fabricated curb must be in place before unit is hoisted to the roof.

Roof Mounting Curb (frame) must be installed on a flat, level section of the roof (max. of 1/4" per foot pitch), providing a level mounting surface for the unit. In addition, provide sufficient height above the roof to prevent water from entering unit.

In locations where deep snows are encountered,RAlSE THE UNlT A MINIMUM OF 12" OFF THE ROOF, DECK OR SLAB—the chance of the coil being blocked with snow will be reduced. The water that occurs during the defrost has a better chance of flowing from the vicinity of the unit.

Roof Mounting Curb used with WCY—F models is approximately 14" high. This is normally sufficient height to prevent snow blockage and additional clearance is not necessary.

AVOID LOCATING THE UNIT WHERE SNOW TENDS TO DRIFT. This will reduce the times when it is necessary for the customer to remove the snow from around the unit. MAKE CERTAIN THE CUSTOMER KNOWS THAT SNOW ACCUMULATIONS SHOULD BE REMOVED FROM THE SIDES OF THE UNIT FOR BEST EFFICIENCY.

A snow drift barrier may be installed around the unit to prevent a build up of snow on the sides of the unit. The barrier should be of sufficient distance from the unit to prevent restriction of airflow to and from unit.

LOCATE THE UNIT SO THAT THE WATER VAPOR THAT DIS- CHARGES UPWARD DURING DEFROST DOES NOT CONDENSE ON WINDOWS AND FOG THEM OR CAUSE ICICLES TO FORM ON OVERHANGS.

1.Be sure the mounting curb spans structural members (trusses) of the roof, thereby providing sufficient support for weight of the unit, curb and duct(s) plus any accessories (factory or field installed). See Figures 1, 2, 3, 4, 5, 6, 7, 8, 9,10,11 and 12.

NOTE: If any internal accessories are to be added to the unit it should be done at the shop if at all practical.

2.Unit should be positioned so Roof-Run-Off water does not pour directly on unit.

WCY036G1, WCY042G1, WCY060G1, WCY048G1, WCY030G1 specifications

The Trane WCY series is a line of water-cooled chillers that exemplify innovation and efficiency in commercial HVAC systems. Models such as WCY024G1, WCY030G1, WCY042G1, WCY048G1, and WCY060G1 are designed to meet diverse cooling needs while maintaining energy efficiency and reliability.

One of the standout features of the WCY series is its use of advanced chiller technology, which incorporates a reliable, scroll compressor. These compressors are known for their durability and efficiency, allowing the chillers to provide cooling capacity ranging from 24 to 60 tons, making them suitable for various building sizes and applications. The efficient design of these compressors contributes to lower energy consumption, leading to potential savings on operational costs.

Another significant characteristic of the Trane WCY series is its use of microchannel heat exchangers. These heat exchangers feature a compact design that minimizes refrigerant charge and enhances heat transfer performance. The microchannel technology not only improves overall efficiency, but it also contributes to a smaller physical footprint for the units, allowing for flexible installation options in tight spaces.

The chillers are equipped with advanced controls that optimize performance, enabling users to easily monitor and adjust system operations through a user-friendly interface. The integration of Trane's Tracer™ control technology enhances operational efficiency by providing real-time data and analytics, which can inform maintenance needs and system adjustments.

In addition to these features, the WCY series includes robust construction that ensures reliability in diverse environments. The units are designed to withstand various weather conditions and are built with corrosion-resistant materials to enhance durability.

Furthermore, the Trane WCY chillers are designed with sustainability in mind. They utilize refrigerants with low global warming potential (GWP), aligning with contemporary environmental standards and enhancing the overall sustainability of building operations.

In summary, the Trane WCY024G1, WCY030G1, WCY048G1, WCY060G1, and WCY042G1 chillers represent cutting-edge technology in water-cooled cooling solutions. With their efficient compressors, innovative heat exchange design, advanced controls, and commitment to sustainability, these chillers are an excellent choice for commercial buildings seeking reliable and efficient cooling solutions. Whether for new installations or retrofits, the Trane WCY series offers versatility and performance that meets the demands of modern HVAC applications.
