How to Install the NHZ280426G460 Air Conditioner

This guide provides step-by-step instructions for installing the NHZ280426G460 air conditioner in a suitable enclosure, ensuring proper functionality and safety.

Estimated time: 1h

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Mounting gasket kit

  1. Inspect the air conditioner

    Check for any visible damage and verify that the unit is functioning correctly before installation. Ensure the air conditioner has been upright for at least five minutes if it was previously horizontal.

  2. Prepare the installation site

    Select a location for the air conditioner that maintains at least six inches of clearance on one side and twenty inches in front for cover removal. Use the cutout template provided to prepare the enclosure.

  3. Mount the air conditioner

    Using the mounting gasket kit, secure the air conditioner to the enclosure. Ensure the gasket is not damaged during installation. Start bolts by hand to avoid cross-threading before tightening.

  4. Wire the air conditioner

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

  5. Configure the controller

    Adjust the controller to the desired cabinet temperature. Refer to the manual for specific instructions on changing program settings.

  6. Test the air conditioner

    After installation, power on the unit and verify that the evaporator blower starts running. Ensure the compressor operates correctly by setting the thermostat below the ambient temperature.
