Visually inspect plug connection and wiring condition for loose connections or damage.
Not Good: Secure the connection or perform wire repair [electrical shock warning] unplug Misting system before attempting to perform any wire repair on the system. Consult a professional electrician for repairs on power source wiring.
Good: Proceed to the next step-
Is GFCI/breaker tripped?
No: Proceed to step 3 in this section.
Yes: Proceed to step 4 in this section.
Plug the Mistcooling pump into a different, known-good outlet (the usage of a properly rated extension cord is acceptable for diagnostic purposes):
The system runs properly: The issue is in the original power source, not the Mistcooling system. Please consult a professional electrician for diagnosis of the failed power source.
The system runs but now there is another issue: See the concern selector.
Pump Still does not run: Proceed to Inspect the Water Source.
Reset the GFCI/breaker. Does the pump turn on and continue to run?
Yes: Issue resolved
No: Proceed to the next step-
Did the GFCI/breaker trip again?
No: Return to step 3
Yes: Reset the breaker and plug in another appliance that draws a current similar to the pump. Does the breaker also trip when that appliance is used?
i. Yes: The issue is in the original power source, not the Mistcooling system. Please consult a professional electrician for diagnosis of the failed power source.
ii. No: Contact a Mistcooling technical support agent through email or by scheduling a call.
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. 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 disconnect the outlet line from the pump. Does it operate when turned on?
Not Good: Proceed to Inspect the Powered Pump Components.
Good: Reconnect outlet to output misting line and recheck operation.
i. Good: Issue resolved. (This procedure likely cleared an airlock that was preventing motor operation).
ii. Not Good: Proceed to the next step-
Check for “airlock.” Remove the inlet line from the pump and make sure the water stream is free of air pockets. Disconnect the outlet line from the pump and reconnect the inlet line to the pump. Operate the pump and make sure the water stream is free of air pockets. Turn off the pump. Reconnect the output line to the pump. Remove the end plug or nozzle from the last misting tee and run the pump until a water stream free of air pockets is present. Reinstall the end plug and check the operation.
Good: Issue resolved.
Not Good: Proceed to Inspect the Powered Pump Components.
Inspect the toggle switch for abnormal looseness or an overly soft or “squishy” engagement.
The switch feels loose or “squishy”: Replace the toggle switch. MC60180
The switch feels normal: Proceed to the next step-
Remove maintenance panels to access both sides of the Motor* [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 the wiring for any loose connections or damage.
Not Good: Have a professional electrician perform wire repairs.
Good: Proceed to the next step-
Are there any timers or controllers on the system?
Yes: bypass the timer/controller and recheck the operation.
i. Bypassing the controller fixed it: Contact a Mistcooling technical support agent through email or by scheduling a call.
ii. Bypassing the controller did not fix it: Proceed to the next step-
No: Proceed to the next step-
Is the water supply a pressurized or tank-fed source?
Pressurized Source: Proceed to Step 5 in this section
Tank fed: Proceed to Step 6 in this section.
Inspect Pressure switch: Bypass the pressure switch by moving the bottom wire to the middle terminal on the switch (it can also be bypassed by unplugging both wires and using a jumper wire). Recheck operation:
All operation returns to normal: Replace the pressure switch. MC60580.
Some operation resumes, but not all: Replace the pressure switch. MC60580 but also continue diagnosis by returning to the concern selector and choosing the new matching concern.
No operation resumes/ no change: Contact a Mistcooling technical support agent through email or by scheduling a call.
Open the pump maintenance panel to access the wires from the float switch. Remove the wire caps and tie the float switch wires together temporarily to bypass the float switch. Restore power when safe to do so, and recheck operation.
All operation returns to normal: Replace the float switch. Contact a Mistcooling technical support agent through email or by scheduling a call.
Some operation resumes, but not all: Replace the float switch (Contact a Mistcooling technical support agent through email or by scheduling a call) but also continue diagnosis by returning to the concern selector and choosing the new matching concern.
No operation resumes/ no change: 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-
Open the tank and verify that the float and sensor are positioned correctly (if the float and detector are stuck facing down, it will not allow power to the pump)
Not good: Reposition the float and sensor properly so that the sensor is “up” when the tank is full. Does proper operation resume?
i. Yes: Issue Resolved.
ii. No: Proceed to the next step-
Good: 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 in 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.
