How to Install the HazLoc Vortex A/C Model VHL50160

This guide provides step-by-step instructions for installing and configuring the HazLoc Vortex A/C Model VHL50160 to ensure effective cooling in hazardous locations.

Estimated time: 1h

Tools needed:

Screwdriver, Wrench, Drill, Wire strippers

Supplies needed:

Mounting screws, Vinyl tubing, Check valves, Cold air mufflers, Compressed air filter

  1. Select the installation location

    Choose a flat horizontal or vertical surface on a Type 4X enclosure for mounting the HazLoc Vortex A/C, ensuring sufficient clearance for thermostats and air outlets.

  2. Mount the unit

    Cut two 1 15/16" diameter holes in the enclosure at 4" centers. Insert the threaded portions of the HazLoc Vortex A/C into the holes and secure with 1-1/2" electrical locknuts from inside the enclosure.

  3. Attach the Check Valves

    Connect the Check Valve assemblies to the cold air outlets of the HazLoc Vortex A/C, ensuring the arrows on the valves point away from the unit.

  4. Install the Cold Air Mufflers

    Mount the Cold Air Mufflers inside the enclosure using the supplied mounting clamps. Ensure they are positioned correctly for optimal airflow.

  5. Connect the vinyl tubing

    Cut lengths of the supplied 5/8" vinyl tubing to connect the Check Valves to the Cold Air Mufflers, ensuring no sharp bends or kinks in the tubing.

  6. Install the compressed air filter

    Connect the compressed air filter to the inlet of the HazLoc Vortex A/C using 3/8" pipe, ensuring the filter is positioned in a non-hazardous area.

  7. Connect the compressed air supply

    Attach the compressed air supply to the inlet of the air filter, ensuring the air pressure is regulated between 90 to 100 psig.
