Overview

The nVent ProAir Harsh Environment Indoor Air Conditioner (SKU: CR290226G030) is a robust, corrosion-resistant cooling solution engineered for industrial applications where equipment must operate reliably in aggressive environments. Designed by nVent, a global leader in thermal management and electrical solutions, this unit delivers 2700 BTU of cooling power at 230V with dual-frequency compatibility (50/60Hz), ensuring consistent performance across global power infrastructures. The ProAir series is specifically built to protect sensitive electronic components, control panels, and machinery exposed to corrosive atmospheres, such as chemical processing plants, wastewater treatment facilities, marine environments, and outdoor industrial enclosures. Key features of the ProAir Harsh Environment Air Conditioner include a corrosion-resistant steel housing with a light gray powder-coated finish, providing superior durability against salt spray, humidity, and chemical vapors. The unit’s hinged service door enables rapid access for maintenance, reducing downtime and simplifying routine inspections or filter replacements. With minimal external fasteners, the design minimizes potential entry points for contaminants while maintaining structural integrity. An optional protective hood (sold separately) further enhances splash resistance, making the ProAir ideal for applications where water or caustic liquids may be present. This air conditioner is part of nVent’s ProAir line, a trusted brand in industrial thermal management, known for its engineering excellence and adherence to stringent industry standards. The CR290226G030 model is UL-listed and designed for indoor use, featuring a compact footprint that fits seamlessly into control cabinets, electrical enclosures, or NEMA-rated housings. Its 4.6A/3.9A current draw (50Hz/60Hz) ensures energy efficiency without compromising cooling capacity, while the 2700 BTU rating is optimized for small to medium-sized enclosures where precise temperature control is critical. Industries that benefit from the ProAir Harsh Environment Air Conditioner include oil & gas, mining, food & beverage processing, pharmaceutical manufacturing, and data centers with harsh ambient conditions. The unit’s ability to maintain internal enclosure temperatures within tight tolerances prevents overheating of critical components, extending equipment lifespan and reducing unplanned maintenance costs. Installation is straightforward, with mounting options for wall or cabinet integration, and the unit’s quiet operation makes it suitable for noise-sensitive environments. nVent’s commitment to innovation and reliability is evident in the ProAir series, which combines rugged construction with user-centric design.

How to Install the CR290426G017 Air Conditioner

This guide provides step-by-step instructions for installing and configuring the CR290426G017 air conditioner, ensuring proper functionality and safety.

Estimated time: 45m

Tools needed:

Screwdriver, Wrench, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Gasket kit, Terminal connectors

  1. Inspect the air conditioner

    Check for any visible damage and ensure the unit is functioning properly before installation. Do not operate the unit if it has been in a horizontal position; allow it to stand upright for at least five minutes.

  2. Prepare the mounting area

    Using the cutout dimensions provided in the manual, prepare the air 'IN' and 'OUT' openings and the mounting bolt hole pattern on the enclosure.

  3. Install gaskets

    Apply the gasket kit to the rear of the air conditioner to ensure a proper seal before mounting.

  4. Mount the air conditioner

    Secure the air conditioner to the enclosure using the provided mounting bolts and washers. Start bolts by hand to avoid cross-threading, then tighten with a wrench.

  5. Connect the power supply

    Refer to the nameplate for electrical requirements and connect the power cord to a properly grounded power supply. Ensure the circuit is fused with a slow blow or HACR circuit breaker.

  6. Test the air conditioner

    Before finalizing the installation, power on the unit and allow it to run for 5 to 10 minutes. Check for excessive noise or vibration and ensure the compressor and blowers are operating correctly.

  7. Adjust the temperature controller

    If necessary, adjust the Level I temperature controller located inside the air conditioner by turning the adjustment screw to set the desired temperature.

  8. Finalize installation

    Close the front panel of the air conditioner and secure it with the front panel screw. Restore power to the unit for operation.
