Maintenance

Preventive Maintenance

Maintenance on the unit is simplified with the following preventive sugges- tions:

Filter maintenance must be performed to assure proper operation of the equipment. Filters should be inspect- ed at least every three months, and re- placed when it is evident they are dirty. Filter sizing includes:

!WARNING

Hazardous

Voltage!

Disconnect all electric power, in- cluding remote disconnects and discharge motor start/run capaci- tors before servicing. Follow prop- er lockout/tagout procedures to ensure the power can not be inad- vertently energized. Failure to dis- connect power before servicing could result in death or serious in- jury.

Check the contactors and relays within the control panel at least once a year. It is good practice to check the tight- ness of the various wiring connections within the control panel.

A strainer (60 mesh or greater) must be used on an open loop system to keep debris from entering the unit heat exchanger and to ensure a clean sys- tem.

For units on well water, it is important to check the cleanliness of the water- to-refrigerant heat exchanger. Should it become contaminated with dirt and scaling as a result of bad water, the heat exchanger will have to be back flushed and cleaned with a chemical that will remove the scale. This service

should be performed by an experi- enced service person.

!WARNING

Hazardous

Chemicals!

Coil cleaning agents can be either acidic or highly alkaline. Handle chemical carefully. Proper han- dling should include goggles or face shield, chemical resistant gloves, boots, apron or suit as re- quired. For personal safety, refer to the cleaning agent manufactur- ers Materials Safety Data Sheet and follow all recommended safe handling practices. Failure to fol- low all safety instructions could result in death or serious injury.

It should be noted that the water qual- ity should be checked periodically. See Table 9.

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.
