OPERATION
SAFETY
MAINTENANCE
1. Fill the water tank with clean fresh water before 
every use. (Ice may be added.)
2. Aim mister downwind for best results. If more than 
one mister is used, arrange them in an arc around 
the misting area.
3. Plug the GFCI safety plug into a 120 VAC 60 Hz 
grounded outlet. 
4. Turn on the two-position switch located on top of the 
pump case. Turn to FAN for air movement only or 
FAN/PUMP for air and mist.
5. Drain unused water at the end of each use period.
NOTE: The misting hub located in the center 
of the fan is equipped with four nozzles. The 
output volume of water vapor can be reduced 
by replacing one or two of the nozzles with the 
plugs provided.
The fan will mist for approximately five hours on 
10 gallons of water.
CAUTION! Electrical shock hazard. Pinch hazard. 
Trip hazard.
• Serious injury or death may occur.
• Only plug the fan into properly grounded outlets.
• Disconnect the power cord from the electric supply 
before filling, servicing, or moving the fan.
• Test the GFCI safety plug before using.
• Do not carry the fan by the motor, electric cords, 
hose line, fan guard or support bars.
• Do not touch the fan motor during use or directly 
after. It may be hot.
• Do not operate the fan without guards in place.
• Do not insert anything into the fan guard while 
operating.
• If the fan tips over, unplug the power cord and dry 
any wet areas before setting up the fan.
• Position all electric cords to lie flat on the ground or floor.
• Never use during rain, sleet, hail, snow or any other 
inclement weather conditions.
• Never operate pump without water supply.
• Check for leaks. If leaks are found, turn pump off and 
hand tighten leaky fittings.
• Excessively hard water with high-solids can plug nozzles.
• A plugged filter caused by poor-quality water can 
restrict flow to the pump, causing permanent damage.
• Never allow condensation from the nozzles to come 
into contact with surfaces. Redirect the fan to prevent 
condensation from forming on nearby surfaces. 
FILTER
Filter maintenance requirements will change 
with changing water conditions.
Inspect the filter frequently and change as needed. A 
dirty filter will restrict water flow to the pump and can 
cause permanent damage.
SYSTEM DRAIN/STORAGE
Before storing the fan, empty the water tank and drain 
all water from the system to prevent calcification and 
algae forming on the components. 
Regularly clean the mister and water tank with an anti-
bacterial solution. 
NOZZLES
Check nozzle function regulary. The spray pattern from 
the nozzle should have an even cone shape. Clean or 
replace the nozzle as needed.
To clean the nozzle:
1. Remove the nozzle from the misting hub.
2. Soak the nozzle in a scale or lime removing solution.
3. If, after cleaning the nozzle fails to work properly, 
replace with the spare nozzle provided.
CAUTION! Tighten the nozzle by hand only.
