Inspect system installation/expansion: Does the system match the original system design? (6-40 nozzles, up to 100ft)
No: return system to original specifications and recheck operation.
Yes: Proceed to Inspect the Water Source.
Is the system supplied water by a pressurized source or is it tank fed?
Tank-fed: Proceed to Tank-fed Water Source Inspection.
Pressurized source: Proceed to the next step-
Visually inspect the water source: Make sure the water is turned fully on. Make sure lines/hoses are free of leaks. Make sure lines/hoses are not kinked, crimped, blocked, twisted, or being squeezed by any objects pressing against them.
Not Good: address the issue and recheck the operation.
i. Good: issue resolved.
ii. Not Good: Proceed to the next step-
Good: Proceed to the next step-
Inspect water source output: Start by disconnecting the source line from the pump inlet. Is proper flow and pressure present?
Not Good: work backward down the line by disconnecting the line between the filter to the pump, the filter(s), any line between the filter and source outlet, and any garden hose between the line and source outlet, one at a time to identify the item restricting water flow. Replace as necessary. Find replacement parts here. (If the source outlet itself is restricted, a professional plumber should be contacted. The Mistcooling system is not the issue.)
Good: Proceed to the next step-
Inspect filter for debris and replacement schedule. (Filter is contained inside pump case on this model with the exception of produce case misting systems) An overdue/dirty filter may still interfere with pump operation even if some flow is present.
Not Good: replace the filter. Find filters here.
Good: Proceed to the next step-
Reconnect the known-good water source to the pump inlet, and proceed to Investigate the Nozzle Output.
Purge possible air from the output line: remove the end plug (or last nozzle) from the misting line, connect the misting line to the pump outlet, and turn the pump on until a steady stream of water, free of air pockets, comes out. Reinstall the end plug/last nozzle and recheck operation. Is the mist still uneven?
No: Issue Resolved.
Yes: Proceed to the next step-
Examine the character of the uneven mist:
If misting is strong near the input and gradually weakens as nozzles progress down the line: it is likely due to a lack of pressure in the water source or too many nozzles/too much length. Shortening the output and reducing the nozzles is a possible solution. Recommend a higher pressure system or source booster
If mist output varies irregularly (ex. 2nd and 6th nozzles don’t spray well, but others do): Proceed to the next step-
Try swapping a nozzle that sprays poorly with a nozzle that sprays well. What was the result?
The spray characteristics moved with the nozzle: Remove all misting nozzles and use our Mistcooling Nozzle Cleaner: MC46220. In severe cases, nozzles may still need replacement. If cleaning or replacement of nozzles still does not resolve the issue: Contact a Mistcooling technical support agent through email or by scheduling a call.
The spray characteristics did not move with the nozzle: Disconnect the misting line from the input line. Use compressed air to blow through the lines, removing the nozzles from the clogged tees one at a time. If the issue still is not resolved, Contact a Mistcooling technical support agent through email or by scheduling a call.
Does the arrangement of the tank and pump still match the original system design? (Tank should be elevated about 1 foot above pump- if possible).
No: Please make sure the layout fits the original design. Does proper operation resume?
i. Yes: Issue Resolved.
ii. No: Proceed to the next step-
Yes: Proceed to the next step-
Is the tank full and properly ventilated?
No: Fill the tank and verify proper ventilation. Does proper operation resume?
i. Yes: Issue Resolved.
ii. No: Proceed to the next step-
Yes: Proceed to the next step-
Verify that the is no air caught in the supply line between the tank and the pump inlet: (Disconnect the supply line from the pump inlet and verify that water drains out of the supply line with no air present.)
Water comes out with air bubbles: Allow water to flow until the air is purged, then reconnect to the pump inlet and recheck operation. Does proper operation resume?
i. Yes: Issue Resolved.
ii. No: Proceed to Inspect the Nozzle Output.
Water does not flow or flow is restricted: Address the restriction between the tank and the end of the supply hose. Does proper operation resume?
i. Yes: Issue Resolved.
ii. No: Proceed to Inspect the Nozzle Output.
Water flows freely with no air: Proceed to Inspect the Nozzle Output.
