Misting System Maintenance
1. Winterization: Mist Cooling Systems
To help maintain the integrity of the mist system and to prevent unnecessary damage, it is important to winterize the mist pump and other components of the misting system BEFORE temperatures drop below freezing. As water becomes Ice, it needs more room to expand. Even a one night of freeze can damage the mist pump, burst a misting line or break filter and mist fittings. How do i winterize my misting system?
A. To winterize:
- Turn off water supply, Unplug the misting pump.
- Open filter housing and drain all water from the filter.
- Drain the inlet tubing going to and from filter into the mistcooling pump inlet.
- Remove tubing from outlet fitting on the pump and store the pump indoors, if possible. Otherwise, use compressed air to blow out water from inlet/outlet of the pump and its internal components.
- Next, remove last nozzle in your mist line. Attach portable compressor on the outlet line (that was removed from the pump outlet) and blow out excess water from the mist line.
- If you do not have access to compressor, simply remove all nozzles from the mist line. By doing so, majority of excess water will drain itself.
- Now is good time to clean your mist nozzles so they will be ready for summer time.
B. Winterization: Mosquito System, Odor Control and Tank based Misting Systems
It is always best before winter arrives, if possible, to run the system to a point where the liquid is at its lowest point in the reservoir.
- Pull the suction line with filter out of the liquid in reservoir.
- You can blow out the mist line with use of compressed air (See steps 4-7 above) OR use an environmentally safe product to winterize your system such as windshield washer fluid. Dump the windshield washer fluid in to a one gallon or larger pail, and then place the suction line into the pail.
- Manually run the pumping unit or (Use “Extra Run” feature) until the windshield washer fluid has filled all tubing lines and nozzles. Once all the insecticide has been purged and you see the windshield washer fluid spraying from all nozzles unplug the power cord.
- Next, pull the suction line out of the windshield washer fluid. Using a cable tie, rope or like method, tie the suction filter to the suction tubing.
- To de-winterize the system, stir the insecticide in the reservoir, untie and place the suction filter in the insecticide liquid... plug the power cord in ... set the time of day and location on the clock timer... start power unit manually (“Extra Run”)and run it until all windshield washer fluid is purged from the system. The system is now ready for automatic operation.
DO NOT USE ANTI-FREEZE PRODUCTS THAT CONTAIN PROPYLENE GLYCOL. PROPYLENE GLYCOL
will damage the internal seals of the pump and void the warranty.
Before putting the system to back in operation for hot summer months, following system checks and maintenance should be performed ensure trouble free operation.
- Check/Change Inlet Filter. Note: Clogged filter blocks water flow into the pump which can cause damage.
- Change the Oil on the mist pump. (Only high pressure pumps)
- Reinstall any other fittings that were removed during winterization.
- Remove last nozzle/end plug from the mist line.
- Turn on water and electric and flush out the system until smooth stream of water comes out. This will remove any air and debris from the line.
- Reinstall the last nozzle/end plug.
- Check for non-working misting nozzles. Clean or replace if needed.
3. Nozzle Cleaning
Mist nozzles .over time do need cleaning or worst case - replacing. The time in-between cleaning or replacing nozzles can depend on water quality. Old nozzles or nozzles that have been sitting without use for an extended period of time may accumulate a dried liquid near the nozzle orifice that can block the spray from exiting.
A popular way to clean mist nozzle is to disassemble the nozzle and blow the housing out with compressed air or tapping the mist nozzle on hard surface to free up the internal pin. However, we recommend use of our specially designed, industrial grade Nozzle Cleaner which instantly loosens rust, hard water deposits and other sediments. Old tooth brush or wire scrubber are good tools for scraping the build-up from the nozzle tip. Individual nozzle-filters are also recommended to increase the life of the mist nozzles.
Filtration is very important for proper operation of misting systems. Most systems have sediment filter on the Inlet side. This helps prevent any large particles from clogging up the nozzles. In order to maintain the proper flow in to the mist system, water filter should be changed every 3 to 6 months or earlier if water quality is bad. Scale free filters can also be added to mist systems to prevent clogging of nozzles due to hard water. Our TAC Scale Free filters are recommended for such locations and lasts up to 2 years.
5. Oil Change
Oil change on high pressure mist pump is just as important (if not more) as oil change on your car. Oil should be changed after initial 50 hours of run time and every 500 hours thereafter. Only manufacturer recommended oil should be used. Our new Oil-Less pumps do not require oil changes.
