General Information

Unit Nameplate

The unit nameplate is located at the front of the unit. It includes the unit model number, serial number, electri- cal characteristics, refrigerant charge, and other pertinent unit data.

Compressor Nameplate

The nameplate for the compressors are located on the compressor shell.

Unit Description

Before shipment, each unit is leak test- ed, dehydrated, charged with refriger- ant and run tested for proper control operation.

Water-to-Refrigerant Coils

The co-axial water-to-refrigerant heat exchanger for the 3/4-ton through 3- ton equipment is constructed of cop- per or cupro-nickel (option) for the wa- ter section and stainless steel for the refrigeration section.

The heat exchanger is leak tested to assure there is no cross leakage be- tween the water and refrigerant gas.

Water Connections

1/2" or 3/4" water connections are lo- cated on the chassis’s upper section and clearly labeled for water-in/out hose to riser hook-up.

Blower/Motor

The blower and motor is located inside the unit cabinet. The blower and motor may be removed from the cabinet through the chassis opening. After re- moving the chassis, the blower as- sembly is strapped into the unit cabinet through a single metal, flexi- ble bracket. We refer to this bracket as a housing belly bracket. After detach- ing one screw at the bottom/front edge of the bracket, the housing and motor are free to be lifted from the fan deck.

Sound Attenuation

Sound attenuation is applied as a stan- dard feature in the product design. The enhanced reduction package includes a heavy gage base plate, and gasket/ insulation around the compressor en- closure.

An optional deluxe sound reduction package is also available. It includes a heavy gage base plate, gasket and in- sulation around the compressor enclo- sure, and vibration isolation between the chassis and cabinet. An additional dampening treatment is applied around the compressor enclosure to achieve greater acoustical reductions.

Controls

The control system offered to control the unit is a Basic 24 volt control for the 3/4-ton through 2-ton retrofit (WPRD) equipment. A 50 VA trans- former is factory supplied on this unit configuration. See wiring diagram on chassis access panel for field wiring connection to the 24 volt mechanical thermostat.

Deluxe 24V Controls

(GET model)

Units containing the Deluxe 24V con- trol design will incorporate a micro- processor-based control board. The Trane microprocessor board is factory wired to a terminal strip to provide all necessary terminals for field connec- tion. The deluxe board is equipped with a random start relay, anti-short cycle timer, brown out protection, compressor disable, unit safety con- trol, diagnostics and a generic relay (which may be available for field use). See page 16 for diagnostic informa- tion.

Power wiring is made at the contactor. The wiring is fed through the left or right conduit tube, and into the cabi- net’s control box (contactor).

ZN510 Controls

(GET option)

Units incorporating the ZN510 control option design will include a digital LonTalkTM certified control board. The control board will support such op- tions as: random start delay, heating/ cooling status, occupied/unoccupied mode and fan/filter status.

Power wiring is made at the contactor. The wiring is fed through the left or right conduit tube, and into the cabi- net’s control box (contactor). See manual WSHP-IOP-2 for diagnostic in- formation.

Schrader Connections Connections for the low and high side of the refrigeration system are located conveniently on the chassis’ top be- neath a sheet metal plate.

GETB specifications

The Trane GETB, known for its exceptional efficiency and reliability, stands as a leader in the commercial HVAC industry. Designed to meet the demands of varying environments, the GETB system is particularly beneficial for buildings requiring constant heating and cooling performance.

One of the standout features of the GETB is its use of the Trane Tracer SC+ building management system. This intelligent control platform allows facility managers to efficiently monitor and manage HVAC settings remotely, optimizing comfort and energy consumption. The integration of smart technology significantly reduces operational costs by promoting energy-saving strategies tailored to specific building requirements.

A notable technology incorporated in the Trane GETB system is the use of advanced variable-speed compressors. These compressors adjust their output based on the needs of the building, providing precise temperature control and minimizing energy wastage. With this technology, the GETB can achieve high efficiencies across various load conditions, which is particularly advantageous during periods of fluctuating occupancy.

Another important characteristic of the GETB is its robust design tailored for durability and longevity. Constructed with high-quality materials and components, the system is engineered to withstand the rigors of continuous operation in industrial environments. This resilience ensures minimal disruptions and maintenance needs, allowing for a seamless integration into any facility.

Additionally, the GETB offers extensive options for zoning and temperature control. With its zoning capabilities, different areas of a building can be maintained at separate temperature settings, enhancing comfort for occupants while contributing to energy conservation. The ability to customize the system to suit specific building layouts makes the GETB a versatile choice for a variety of applications.

Furthermore, the GETB is designed with environmental sustainability in mind. By using refrigerants with lower global warming potential, Trane has focused on reducing the ecological footprint of its products. This commitment to sustainability does not only comply with regulatory standards but also supports building owners looking to achieve green certifications.

In summary, the Trane GETB combines advanced technologies, robust design, and energy-efficient features to provide a dependable HVAC solution for commercial spaces. With its smart controls, variable-speed compressors, and emphasis on sustainability, it represents an ideal choice for those seeking reliable heating and cooling in a dynamic and eco-conscious manner.
