Maintenance for a Misting SystemAll of MEC’s misting systems come with a 1 year warranty on the pumping unit and 5 years on the stainless steel nozzle line, however, proper maintenance of your misting system is necessary to ensure optimum performance and longevity. Oil should be changed on a regular basis. The manufacturer of the pump used in the misting system usually recommends changing the oil every 500 hours. Some owners prefer to change the oil more frequently - at 250 – 300 hours. The types of oil to be used vary, depending on the pump used for your system. MEC recommends that your first oil change is performed after 20 hours of operation, then all subsequent oil changes can be at 500 hour intervals or earlier if you choose. Regularly check the condition of the filters and the incoming pressure gauge at start up to ensure adequate supply and water pressure to your pumping unit. MEC’s misting systems are designed and manufactured with a 4 filtration system, consisting of a 25 micron filter, then through a 10 micron filter, followed by a 5 micron filter, and finishing with a 1 micron filter to ensure as much foreign matter is removed prior to the water entering the pumping system. The order of the filters from 25 down to 1 micron should not be altered since some water sources may contain only large particulates and the need to change only the 25 micron filter can reduce your maintenance costs. If your water pressure or flow is restricted due to clogged filters cavitation of the pump may occur, causing you needless expense to replace the pump. The incoming water pressure should never exceed 100 psi and never be lower than 40 psi.
