Misting Fan Installation Instructions
How to Install a Misting Fan: Step-by-Step Guide
Looking for a smarter way to beat the heat? Misting fans—also known as water fans—offer a powerful and refreshing solution for hot patios, outdoor dining areas, industrial settings, and more. Whether you're a DIY enthusiast or a professional installer, this guide will take you through each step of installing a misting fan to ensure maximum cooling performance and system longevity.

Step 1: Set Up the Pump and Filter System
Begin by placing the water pump in a dry, flat, and sheltered location near a water spigot or hose and a 120V GFI power outlet. Use the included 3-foot hoses to connect your faucet to the filtration system and from the filter to the pump.
If your pump includes a brass reducer fitting at the inlet, be sure to wrap all male threads (both the fitting and feeder hoses) with double Teflon tape to prevent leaks.
Mount the filter bracket by first deciding on a wall location where the feeder hoses can run smoothly—no kinks or tight bends. Mark the four screw holes and drill them using a 3/16" bit if you're using size 8–10 anchors. If mounting on wood, pre-drill pilot holes and use the sharper screws provided.
Open the filter assembly, insert the white filter into the canister, and place the anti-scale cartridge (it looks like a test tube) inside. Hand-tighten the canister, then mount it on the bracket using the blunted screws. Carefully screw the hoses into the proper "In" and "Out" threads of the filter canister, then connect the outlet hose to the pump and the inlet hose to your water source.
Step 2: Attach Nozzle Assemblies to the Fans
The ideal height for mounting patio fans is 8 to 9 feet, angled downward at roughly 30–40 degrees. Mounting hardware is included for wooden surfaces. For cement, stucco, or hollow walls, consult your hardware store for appropriate anchors or toggle bolts.
Most fans have a 1 ¼-inch opening at the center of the guard. Loosen the back bar on the nozzle assembly just enough to leave it slightly threaded. Insert the assembly into the fan guard and twist clockwise until snug. Be sure the slip-lock fitting is positioned vertically or pointed in the direction you plan to run the high-pressure tubing.
Step 3: Mount the Fans
Secure each fan to your walls or ceiling using the supplied hardware or other appropriate anchors for your surface. Turn each fan on high speed to ensure proper function and check that the airflow direction is ideal.
For best cooling results, position the fans 6 to 15 feet away from where people will be seated or working. Remember, each fan will need a GFI outlet or can be hardwired by an electrician to operate from a single wall switch.
Step 4: Run and Connect the High-Pressure Tubing
Cut a 1–3 foot piece of tubing with the supplied cutter, making a perfectly perpendicular cut to prevent leaks. Connect it to the “Out” port of the pump and insert the pressure release valve in line with the tubing. Ensure the nozzle is aimed downward before continuing to the fans.
Use the included clamps every 24–30 inches to secure the tubing along walls or ceilings. Use 90-degree elbows for corners and tees if you plan to branch the tubing in two directions. For clean results, run tubing in the crease where the wall meets the ceiling, or adjust as needed based on your space.
At each fan, insert a slip-lock tee with the middle port pointing downward toward the nozzle. Cut about 3 feet of tubing to connect the tee to the fan’s nozzle. Zip-tie the tubing to the front of the fan guard, trim any excess, and snap the end into the nozzle assembly.
Repeat for each fan. On the final fan, use a 90-degree elbow instead of a tee.
Step 5: Flush the System and Finalize Installation
Before making the final nozzle connection, turn on your water supply halfway and start the pump. Let the system run for 30–60 seconds to purge air and any debris from the lines. Turn everything off, dry the tubing going into the final nozzle, and connect it.
Restart the system. The pressure release valve should discharge briefly until the system reaches full pressure. If you’ve used a lot of tubing, you might need to briefly hold your thumb over the valve to build pressure during initial startup.
Leaks in the system will prevent the pressure from reaching the required 900–1000 PSI. If you detect a leak, press the tubing more firmly into the slip-lock fitting.
Important Safety Tip: Never operate the pump without water! Doing so will damage the pump.
Now, you’re ready to enjoy your misting fan system! Whether you're cooling a busy restaurant patio or relaxing at home, your newly installed water fan setup will keep you—and your guests—cool and comfortable all summer long.
