5. Maintenance

5.1 Periodic General Maintenance

Systematic, periodic general maintenance of the Cold Row unit is required for optimum system performance. General maintenance should include, but is not limited to the following: replacing filters, tightening electrical connections, checking the condensate pans and drain line to ensure they are free of debris, cleaning the interior of the unit, inspecting the units’ components visually, checking level of refrigerant, and ensuring no moisture is in the refrigerant IF APPLICABLE.

Use copies of the Periodic General Maintenance Checklist in this manual (see Appendix A.2) to record periodic general mainte- nance inspections. For assistance, contact Black Box Technical Support. Ensure adherence to all safety statements while perform- ing any type of maintenance.

WARNING

This equipment should be serviced and repaired by a journeyman or a qualified refrigeration technician only.

WARNING

This unit uses high-voltage equipment with rotating components. Exercise extreme care to avoid accidents and ensure proper operation.

Hazardous voltage will still be present inside the electric box at the motor start protectors and circuit breakers, even with the unit turned off at the microprocessor controller. To isolate the unit for maintenance, turn off power at the main power disconnect switch. Always disconnect main power prior to performing any service or repairs.

WARNING

Turn off power to the unit unless you are performing tests that require power. With power and controls energized, the unit could begin operating automatically at any time. To prevent personal injury, stay clear of rotating components as automatic controls may start them unexpectedly.

5.1.1 Filters

The filter is usually the most neglected item in an air-conditioning system. To maintain efficient operation, check the filter every 3 to 6 months and clean or replace it as required.

NOTE: Conditions of spaces vary. Extremely dusty environments may require more frequent filter maintenance.

The air filters are located behind the air intake grille at the rear of the cabinet. To access the filters, unlatch the rear access panel at the top and remove it from the cabinet.

5.1.1.1 Cleanable Filters

Cleanable filters are spring loaded in the holding trays in the access panel. Using a flat-head screwdriver, gently push the filters to one side and remove the old filters from the trays (Figure 5-1).

CRDX-W-FS-12KW, Black Box Cold Row DX, CRDX-W-FS-24KW, CRDX-A-FS-24KW, CRDX-A-FS-12KW specifications

The Black Box CRDX series consists of high-performance cooling solutions designed to maintain optimal temperature conditions in data centers and server rooms. Key models in this series include the CRDX-W-FS-12KW, CRDX-W-FS-24KW, CRDX-G-FS-12KW, and CRDX-A-FS-24KW. These units are engineered to provide efficient cooling while addressing the rising demands of modern IT infrastructure.

One of the standout features of the CRDX series is its cold row design. This configuration enables targeted cooling delivery directly to the equipment, enhancing efficiency and reducing energy consumption. The airflow management in these models ensures that cooled air is directed where it is needed most, minimizing hotspots and maximizing cooling performance.

Both the CRDX-W-FS-12KW and CRDX-W-FS-24KW models utilize advanced refrigerant-based cooling technology. These units are equipped with electronically commutated (EC) fans, which are highly efficient and quieter than traditional fan technologies. This innovation not only lowers operational costs but also creates a more comfortable environment within the data center.

The CRDX-G-FS-12KW model stands out for its hybrid capabilities, offering both chilled water and direct expansion cooling options. This versatility allows facility managers to choose the best cooling approach based on their specific requirements and current infrastructure. The hybrid system can optimize energy consumption and enhance cooling efficiency, contributing to lower operating costs.

Another noteworthy feature across these models is their intelligent controls and monitoring capabilities. Equipped with sophisticated sensors and control systems, operators can gain real-time insights into temperature fluctuations, humidity levels, and unit performance. This data aids in proactive maintenance and ensures that cooling systems are operating at peak efficiency.

The CRDX-A-FS-24KW, on the other hand, is designed with a focus on adaptability and scalability. This model can be integrated easily into existing network setups, making it an excellent choice for facilities that anticipate future growth or need to adapt to changing cooling demands.

Overall, the Black Box CRDX series exemplifies the latest advancements in cooling technology, offering innovative features designed to support high-density computing environments. With their efficient cooling capabilities, intelligent controls, and flexible design options, these models provide reliable solutions for data centers looking to enhance their cooling systems while reducing operating costs.
