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, disconnect the outlet line from the pump, and turn on the pump (this step will simultaneously clear an airlock if present). Does the pump produce the proper flow of water?
No ( if pressurized source): Proceed to Inspect Solenoid Valve.
No (if tank Fed): Replace the pump. Contact a Mistcooling technical support agent through email or by scheduling a call.
Good: Proceed to Inspect the Output Section/Misting Line.
Remove the maintenance panel* from the pump housing, and identify the solenoid valve on the inlet bulkhead. This solenoid is designed to stop the flow of water into the pump when power is not being supplied. Disconnect the water supply from the exterior pump housing inlet, and disconnect the line between the interior solenoid and the pump/motor assembly. (it can be disconnected before or after the filter). Then connect the water source line to the elbow on the pump motor assembly (or filter if removed there). This step will supply water directly to the pump, bypassing the solenoid. With the output side still disconnected from the pump housing outlet, the inlet connected to the pump, and the water source turned on, turn on the pump and see if a proper flow of water is produced from the outlet.
Good: Replace the solenoid valve. MC60460
Not good: Replace the pump. Contact a Mistcooling technical support agent through email or by scheduling a call.
*Note [electrical shock warning] contacts inside the housing may have live voltage present. The pump should be unplugged from the power source at any time that internal components are inspected or contacted.
Visually inspect output lines and all connections for any physical damages such as bulges, creases, cuts, splits, leaks, etc.
Not Good: Repair/replace as necessary. (For leaks specifically, see Concern 4: leak(s).)
Good: Proceed to the next step-
Inspect system installation/expansion: Does the system match the original system design? (6-12 nozzles, up to 50ft)
No, the system has been expanded: Return the system to the original specifications and recheck operation:
i. System operates properly: Issue Resolved.
ii. System still doesn’t operate properly: Proceed to the next step-
Yes: Proceed to the next step-
Purge 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 check the operation.
Steps could not be completed. No water comes out with the end plug/last nozzle removed: Remove the misting line from the pump outlet, backflush line with compressed air, and perform this step again. If the step still cannot be completed, Contact a Mistcooling technical support agent through email or by scheduling a call.
Misting returns to normal: Issue resolved.
There is still no mist present or misting is uneven. 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.
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 proceed to Step 5 of Inspect Water Source.
Water does not flow or flow is restricted: Address the restriction between the tank and of end of the supply hose, then proceed to Step 5 of Inspect Water Source.
Water flows freely with no air: Proceed to Step 5 of Inspect Water Source.
