What should I do if misting nozzles plug up?
Cleaning Nozzles - Replace or clear obstructed or clogged nozzles.
Nozzles may be cleared by scraping the stainless steel end with flat surface of a knife or screwdriver. To remove nozzle, turn in counter-clockwise direction. Nozzles may be routinely cleaned by soaking in solution of LIME AWAY!" or CLR overnight. Rinse thoroughly after soaking. Replace nozzle by turning in clockwise direction until snug.

Where do I place my patio mist line system?
Place mist line around the perimeter of the area to be cooled. This forms a mist curtain, a cooling barrier between the protected area and the outside heat. The mist line should be mounted 8' to 10' above the ground.

How much water does a misting system actually use?
This will vary depending on the size of the system and the number of nozzles to be used.
You can download the "Nozzle Pump Performance" for more information.

Do I need a filter for my system?
Our high pressure systems are with filters.
For our low and med pressure systems you can use our Poly-Phosphate Filters. The unique Filters actually accomplishes two things. First, it will filter out any sediment from the water supply thereby preventing it from getting into the mist line and plugging the nozzles. Second, the filter contains phosphate crystals which are designed to surround the hard water deposits (calcium, sodium, and magnesium) and prevent them from adhering to the misting nozzle. This will also help eliminate the hard water buildup and will keep the mist system operating at peak performance for a longer period of time.

Is there any maintenance required?
The only maintenance required for a properly designed misting system is a periodic cleaning of the nozzles and an annual check-up for the pump. This check-up may include adding or changing of the oil and tightening or replacing of fan belts (only on the pulley driven pump models), and changing of the filter cartridge. Misting Fan Systems require very little maintenance. We do recommend some preventative care and cleaning for the nozzles.

How Does It Work?
MIST&COOL!" Outdoor Cooling Systems employ evaporative cooling to effectively cool and condition the environment. Using our proprietary misting nozzles, an ultra fine mist is introduced into the environment which interacts with the air to cool, clean, humidify and to repel flying insects.

Maximum number of nozzles that can be used
at different water pressures:

 
1/2 Professional System 3/8" Do-It-Yourself System
Water Pressure Max. # of Nozzles Water Pressure Max. # of Nozzles
25 psi 6 30 psi 6
40 psi 18 40 psi 18
50 psi 30 50 psi 30
70 psi 42 70 psi 46
180 psi 54 90 psi 62
250 psi 58 100 psi 62
    120 psi 106
 
Our heaviest duty system is designed to work with house pressures and pump aided pressures up to 250 psi. Higher pressures produce more water volume and an even finer mist that evaporates more efficiently. This system is designed for optional installation flexibility and maximum number of nozzles at pressures up to 125 psi. Besides normal patio applications, this system works exceptionally well in greenhouse applications. *Normal house pressures range between 35 psi and 90 psi.
 
INDOOR COOLING
   
How Many Fans Do I Need?
Each Model 924 and Model 624 High Efficiency Portable Cooler moves approximately 7500 cubic feet (230 cubic meters) of air per minute; this number can be greatly increased where positive pressure ventilation techniques can be employed. Generally speaking, to achieve maximum cooling in indoor or protected areas you will want to transfer the total volume of air in the space being cooled every 1 to 2 minutes.
 
Indoor Cooling
The appropriate transfer time will depend on the space's insulation, how closed in it is (is it a warehouse or a canopy), prevailing humidity, acceptable humidity increase and the total temperature drop desired.

When cooling indoor areas, it is important to remember that you will need to take advantage of any natural flow of air. You can check for existing ventilation by turning on the mist without the fan on and watch where the mist goes. You will also need to determine your source of outside air and where your outlet for the air is. Very often the outlet will be a door or a window on the opposite side of the structure from the inlet air.
 
Example:
Factory 50' (15 m) length x 80' (25 m) width x 15' (4.7 m) ceilings
Totally enclosed structure with fairly good insulation
Complete air transfer every 2 minutes

Calculation of Volume
Length x Width x Ceiling Height
50' x 80' x 15' = 60,000 cubic feet
 
Metric Example:
Factory 16 m x 25 m x 4.7 m = 1880 cubic meters (m)
 
Calculation of Fans Needed=Volume/(Fan VolumexTransfer Time)
60,000 / (7500 cubic feet x 2 minutes) = 4 fans
1880 / (230 cubic meters x 2 minutes) = 4 fans
 
Four fans will completely transfer the air in this structure every two minutes and should effectively cool this factory. The fans should be placed in the oscillation mode to spread the mist throughout the factory and should be pointed in a direction that keeps the air flow moving in the desired direction.
 
OUTDOOR COOLING:
The ability to cool outdoor areas depends on one major factor - the wind. With either light wind or no wind you can achieve some remarkable results depending on temperature and humidity . Normally speaking in outdoor areas it is advisable to use .012" nozzles. (The exception being areas with extremely highhumidity-60% and above.) Cooling outdoor areas is relatively straight forward and can be broken into 2 different types:
XXXXXXXX
  1. Athletic and Amusement Cooling
    In this type of cooling, the people don't mind getting damp, and more often then not prefer to. Generally, fans are placed at head height, so people can stand directly in front of the fan.
  2. Factories/Hospitality
    When cooling a large area where the people don't want to notice the moisture. The fan(s) should be set at their highest level with the fan, aimed slightly above the horizon with the oscillation set to match the area being cooled. If possible place the fan 10-20' behind the area to be cooled. This will allow the cooled air to settle and keep the units sound from being bothersome.
