Inspection Details and Safety Controls

Unit ID, location, and asset tag verified

Record the CRAC/CRAH unit identifier, room/row location, and asset tag match to the maintenance schedule.

Work area accessible and free of immediate hazards critical (required)

Verify clear access to the unit, no standing water, no blocked panels, and no trip hazards in the work zone.

Yes No N/A

Lockout-tagout and energized work controls in place as required critical (required)

Confirm site LOTO procedure and NFPA 70E / site electrical safety controls are followed before opening energized compartments.

Yes No N/A

Required PPE used for the task critical (required)

Verify appropriate PPE for the task, such as eye protection, gloves, and arc-flash PPE if applicable to the site procedure.

Yes No N/A

Inspection date and inspector recorded

Enter the date/time of inspection and the responsible inspector or competent person.

Filters and Airflow Condition

Filter differential pressure within site acceptable range critical (required)

Measure the filter differential pressure and compare it to the site or manufacturer acceptable range.

Filters installed correctly and free of bypass gaps critical (required)

Verify filters are seated properly, frames are intact, and there is no visible air bypass around the filter bank.

Yes No N/A

Filter media condition acceptable

Check for excessive dust loading, damage, collapse, moisture intrusion, or odor indicating replacement is needed.

Yes No N/A

Supply and return airflow unobstructed critical (required)

Confirm grilles, louvers, and return paths are clear of obstructions and not blocked by stored materials or cabling.

Yes No N/A

Fan operation normal with no abnormal vibration or noise critical (required)

Observe fan start-up and running condition for unusual vibration, rubbing, bearing noise, or alarm conditions.

Yes No N/A

Humidifier and Condensate Management

Humidifier output within target range critical (required)

Measure or verify humidifier output against the unit setpoint and site humidity control requirements.

Humidifier reservoir, electrodes, or steam canister condition acceptable

Inspect the humidifier components for scale, wear, leaks, corrosion, or end-of-life indicators.

Yes No N/A

Water supply and drain lines secure and leak-free critical (required)

Check water supply, drain tubing, traps, and fittings for leaks, kinks, blockage, or loose connections.

Yes No N/A

Condensate pan and drain path clear critical (required)

Verify the condensate pan is clean, drain path is open, and no standing water or overflow condition is present.

Yes No N/A

Sensors, Controls, and Alarms

Temperature sensor calibration verified critical (required)

Compare the unit temperature sensor reading to a reference instrument or site calibration standard.

Humidity sensor calibration verified critical (required)

Compare the humidity sensor reading to a reference instrument or site calibration standard.

Pressure sensor or differential pressure reading reasonable

Verify pressure readings are stable, plausible, and consistent with the unit operating condition and site trend history.

Yes No N/A

Alarms, setpoints, and BAS/BMS communications functional critical (required)

Confirm alarms display correctly, setpoints are within approved limits, and the unit communicates to the building management system if applicable.

Yes No N/A

Underfloor Pressure Mapping and Room Air Distribution

Underfloor static pressure measured at required points

Record underfloor pressure readings at the site-defined measurement points or tile locations.

Underfloor pressure meets site target critical (required)

Enter the measured underfloor static pressure and compare it to the approved target for the room.

Floor tiles, cable openings, and blanking panels intact critical (required)

Verify raised-floor tiles are seated, cable cutouts are sealed as required, and blanking panels are installed to prevent bypass air.

Yes No N/A

Final Condition, Deficiencies, and Sign-Off

Deficiencies documented with corrective actions

Record all non-conformances, affected components, and required follow-up actions.

Inspection completed and signed off critical (required)

Confirm the inspection is complete and the inspector signs the record.
