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.
