Overview

The nVent ProAir Harsh Environment Outdoor Air Conditioner (SKU: CR290216G035) is a robust, corrosion-resistant cooling solution designed to protect sensitive electronic components and equipment in extreme outdoor environments. Engineered for durability and reliability, this 2700BTU, 115V unit delivers consistent thermal management where standard air conditioners would fail due to moisture, salt spray, or chemical exposure. The ProAir series from nVent is trusted by industrial professionals across oil & gas, marine, telecommunications, and manufacturing sectors for its ability to maintain optimal operating temperatures in harsh conditions while minimizing maintenance downtime. At the core of the ProAir’s design is its corrosion-resistant steel housing and smooth surface finish, which prevent rust and degradation from prolonged exposure to corrosive elements. The unit features a hinged door for rapid service access, reducing maintenance time and costs—a critical advantage in remote or hard-to-reach installations. Optional hoods provide additional protection against splashed water, ensuring reliable performance even in heavy rain or high-humidity environments. With a compact footprint and lightweight design, the ProAir is ideal for enclosures housing PLCs, drives, control panels, or other critical electronics that require stable temperatures to prevent overheating and component failure. Professionals select the ProAir Harsh Environment Air Conditioner for its combination of durability, efficiency, and ease of installation. The unit operates on standard 115V power with a frequency of 50/60Hz, drawing 7.4A of current to deliver 2700BTU of cooling capacity—sufficient for small to medium-sized enclosures. Its gray steel construction not only resists corrosion but also blends seamlessly into industrial settings, while the few fasteners simplify assembly and reduce the risk of loose components in vibrating environments. nVent’s reputation for engineering high-performance thermal management solutions ensures that the ProAir meets stringent industry standards, including those for NEMA 3R compliance, making it a go-to choice for engineers and facility managers prioritizing longevity and reliability. Typical applications include outdoor telecom shelters, marine control rooms, oil & gas field enclosures, and manufacturing plants where equipment must operate in corrosive atmospheres. Installation is straightforward, with mounting options for wall or floor placement, and the unit’s design accommodates easy integration with existing HVAC systems or standalone operation. For projects requiring additional protection, nVent offers compatible accessories such as hoods and mounting kits, further enhancing the ProAir’s versatility. Whether deployed in coastal regions, chemical processing facilities, or remote industrial sites, the ProAir Harsh Environment Air Conditioner provides unmatched performance where conventional cooling solutions would falter, ensuring uninterrupted operation of critical systems.

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.
