!WARNING

Live Electrical Components!

During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety pre- cautions when exposed to live electrical components could result in death or serious injury.

1.Set the thermostat to the highest position.

2.Set the thermostat system switch to COOL with the fan control to AUTO. The compressor should NOT run.

3.Reduce the temperature control setting until the compressor, reversing valve, solenoid valve, and loop pump are energized. Adjust water flow utilizing pressure/temperature plugs and comparing to tables con- tained in specification sheet data. Water leaving the heat exchanger should be warmer than the entering water temperature (approximately 9°F-12°F); blower operation should be smooth; compressor and blower amps should be within data plate ratings; the suction line should be cool with no frost observed in the refrigerant circuit.

4.Check the cooling refrigerant pressures against values in Table OP1. (Page 21).

5.Turn the thermostat switch to the OFF position. Unit should stop running and the reversing valve should de-energize.

6.Leave unit off for approximately FIVE minutes to allow for pressure equalization.

7.Turn the thermostat to the lowest setting.

8.Set the thermostat system switch to the HEAT position.

9.Adjust the temperature setting upward until the unit is energized. Warm air should blow from the register. A water temperature decrease of approximately 5°F-9°F leaving the heat exchanger should be noted. The blower and compressor operation should be smooth with no frost observed in the refrigeration circuit.

10.Check the heating refrigerant pressures against values in Table OP1. (Page 21)

11.Set the thermostat to maintain the desired space temperature.

12.Instruct the owner on system operation.

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.
