Troubleshooting

!WARNING

Hazardous Service Procedures!

The maintenance and trouble shooting procedures recommend- ed in this section of the manual could result in exposure to electri- cal, mechanical or other potential safety hazards. Always refer to the safety warnings provided throughout this manual concern- ing these procedures. When possi- ble, disconnect all electrical power including remote discon- nects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be in- advertently energized. When nec- essary to work with live electrical components, have a qualified li- censed electrician or other indi- vidual who has been trained in handling live electrical compo- nents per these tasks. Failure to follow all of the recommended safety warnings provided, could result in death or serious injury.

Preliminary Trouble Inspection If operational difficulties are encoun- tered, be sure to perform the prelimi- nary checks before referring to the troubleshooting chart on page 28.

•Verify that the unit is receiving elec- tric supply power.

•Ensure that the fuses in the fused disconnect are intact.

After completing the preliminary checks, inspect the unit for other obvi- ous problems such as leaking connec- tion, broken or disconnected wires, etc. If everything appears to be in or- der, but the unit still fails to operate properly, refer to the troubleshooting chart on page 28.

General Operation

The standard model is designed for in- door installation. When the unit is in- stalled in an unconditioned space, the unit may not start in cool weather (ap- proximately 45°F). It may then be nec- essary to start the unit in the cooling mode for three to five minutes. The unit may then be shut-off (there will be a two minute time-out of the unit), and restarted in the heating mode. The freeze protection thermostat should also be checked as it may be adversely affected by ambient temperature. Like any other type of mechanical equipment, the unit performs best when it is well maintained.

Operation with a Conventional Thermostat

The unit is equipped with safety con- trols, including high pressure control, low pressure control and a freeze pro- tection thermostat, set to shut off the compressor under abnormal tempera- ture or pressure conditions. If the safe- ties shut off the compressor, a lockout relay prevents short cycling from the abnormal condition. When conditions are corrected, the lockout control can be reset by setting the thermostat sys- tem switch to OFF wait a few minutes for the system pressure to equalize, and then return to HEAT or COOL. If the condition continues, an authorized service person should check out the unit.

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.
