    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.
