How to Install an EZ-Flow Cooling Tower
EZ-Flow cooling towers cool the heat created by waste products. The system is a heat-rejection device that causes the water to evaporate. The humidity created by the cooling tower process is ejected into the atmosphere. This system saves you money and is energy-efficient. Installing an EZ-Flow cooling tower requires a lot of knowledge of HVAC systems. You must know how the airflow of an HVAC system works to install a residential cooling tower properly. The installation is difficult, even if you know about these cost-effective systems.

Attach the tower to the mobile crane by connecting all four corners of the tower with slings. Inspect the cooling tower and mounting frame connections to ensure they are tight. Tighten the connections if necessary. The cooling tower mounting base has four lifting holes where you can connect the slings. Slide the sling onto the hoist hook of the mobile crane. Make sure the sling is not making contact with the sides of the cooling tower.

Ensure that you have chosen a firm, flat foundation to place the cooling tower. Lift the cooling tower and relocate it to the foundation. Ensure that the cooling tower is located close to any structural columns for support. Secure the base of the cooling tower with the anchor bolts. Each bolt is attached to hold-down anchors that came with the cooling tower assembly.

Remove all packing material that surrounds the cooling tower assembly. Inspect and tighten any connections, bolts or screws. Before wiring the cooling tower, ensure all local, state and federal electrical codes are being employed. Install and wire the cutout switch that came with the cooling tower assembly. Run conduit from the motor box to the cooling tower's electrical panel. Use mounting screws and brackets to secure the conduit to the cooling tower. Pull electrical wire from the motor box to the tower's electrical panel and wire the connections, as per the electrical diagram that came with the installation manual.

Connect the PVC piping in accordance with the recommended piping designs found in the installation manual. Run the PVC from the cooling tower to the sump. Make sure that the pipe is sloped so gravity will drain the excess water created by the cooling tower. Before connecting the PVC to the cooling tower, install a shutoff valve in between the joint. Tighten all lock nuts on the PVC with your pipe wrench to ensure inlets and outlets installed on the PVC line are secure.

Connect each piece of PVC pipe with a joint. Cut the PVC to size with a hacksaw or miter saw to ensure the ends are flat and square. Chamfer each end of the PVC to remove any cutting debris. Clean the PVC joint connection and pipe ends with acetone. Wipe any excess acetone off before applying the primer compound. Apply the primer and pipe dope to the PVC joint and pipe ends. Push the pipe end and PVC joint connection together. Hold firmly for 20 seconds before releasing the connection. Wait 24 hours before starting the cooling tower to ensure that all joints are tight.

Tips & Warnings
Inspect all joints after startup to ensure no water is leaking from the PVC.
Check the nameplate of the EZ-Flow cooling tower to ensure you are getting the proper assembly.
Test all electrical connection with a volt meter to ensure you are getting the proper voltage. Low or high voltage will cause the motors to overheat and fail.
