Safety Warning (Read Before)
- The pump will not turn on unless it is supplied with min 40 PSI of water.
- The built-in pressure switch will shut off the pump if inlet pressure drops below 40 PSI.
- DO NOT RUN THIS PUMP DRY if the pressure safety switch is removed or bypassed. The warranty does not cover damage to the pump if it is run without water.
- Do not add secondary controllers, fittings, expansions to systems without consulting a mistcooling tech first. Doing this without consulting a tech will void warranty.
- Install in the location where noise from the pump is not a concern. High-performance oil-less pumps do make noise. However, the Pump can be placed up to 200Ft. Away from 1 st mist nozzle. The noise level of the misting pump is not considered a defect.
- Recommended continuous run time is 12-15 hours. Please contact our technicians if the application needs longer operating hours than recommended.
- Misting Pumps build heat and pressure during operation; allow pumps to cool before handling or repairing the pump.
- Oil-less pumps have a built-in thermal safety switch and may cycle off to cool-off.
- To reduce the risk of electric shock, always disconnect the pump from the power source before handling or servicing.
- A qualified electrician should perform any electrical wiring of the pump.
- These pumps are not intended to be submerged.
- For pumping liquids other than water, please only pump water based and water soluble liquids only. o Do not pump hazardous materials (flammable, acidic, etc.) unless the pump is specifically designed to handle them.
- May cause water leaks. Install in a dry, flat, ventilated area with easy maintenance access.
- Mistcooling, Inc. is not responsible for losses, injury, or death resulting from failure to observe these safety precautions, improper installation,
Noise Level Issue
Misting Pumps Create Some Level of Noise During Operation, But There Are Several Ways to Minimize the Impact:
- Placement: Pumps Can Be Installed Up To 200 Feet Away from The Misting Line Start Point, Reducing Noise Near the Seating or Activity Area. Please Purchase Extra Nylon Tubing From Our Website to Store Pump in Desired Area.
- Speed Control: Using A Speed Controller Lowers Pump RPM, Which Directly Reduces Noise Output.
- Positioning: Place The Pump in A Well-Ventilated Area That Is Not in Direct Line of Sight to Guests (Avoid Direct Sunlight to Prevent Overheating).
Noise Level Comparisons: To Help Put Things in Perspective, Here’s How Our Pumps Compare to Common Household Sounds:
- Mid-Pressure Systems: Mild – About 40 dB (Similar to A Refrigerator).
- High-Pressure Standard (.15 And .30 GPM): Loud – About 70–75 dB (Similar to A Vacuum Cleaner).
- High-Pressure Premium (.5, 1, And 2 GPM): Moderate – About 55–60 dB (Similar to Normal Conversation or A Dishwasher)
Push Lock Fittings
- Cut The Tube Straight, Ensure That the Cut Has Not Made the Tube Out of Shape.
- Also, Ensure That the Tube Has a Smooth Outside Diameter Without Any Burrs or Score Marks Before Inserting It into The Fitting.
- Push The Tubing Through the Collet And O-Ring(S) Until It Bottoms Out Against the Tube Stop.
- The Collet Holds the Tube in Place, And The O-Ring(S) Provide A Leak Resistant Seal. Push And Pull the Tubing Toward and Away from The Fitting to Ensure That It Has Been Installed Properly.
TUBE REMOVAL
- Relieve Pressure from The Tubing and Fitting. Push Uniformly Around the Collet Flange Against the Fitting Body While Pulling the Tubing Away from The Fitting to Release It.
IMPORTANT
- Make Sure There Is No Pressure in The Line While Installing or Removing Push-Lock Fittings. Turn Off the Pump and Remove the Nozzle from The Line to Relieve the Pressure.
- To Effectively Release the Tubing from The Fitting Tubing, Push-Lock Release Tool Also Can Be Used.
- Tubes Are Pushed Approximately 1/2 Inch into Fitting. Fittings Add Ups Around 1/4 Inch in the Tube Runs. Please Consider This While Designing Tube Runs.
PREVENTING LEAKS
- Ensure The Tube Is Cut Straight and Firmly Pushed All the Way into The Fitting.
- Prevent Any Immediate Bends Near Fittings; Clamps Should Be Placed 2 Inch from Fitting Joints.
- If Leaks Persist, Remove the Tube from The Fitting and Cut It Straight Another 1/2 Inch and Firmly Reinsert It into The Fitting.
Nozzles Clogging/Leaking

Nozzles Clogging:
- If Your Misting Nozzles Begin Clogging Abnormally Fast, The Most Common Cause Is a Dirty or Insufficient Filter—Even If the Filter Was Installed Recently. Nozzles Have Extremely Small Openings, So Any Debris or Mineral Buildup In The Water Supply Can Block Them.
- Clogging Is Almost Always a Sign That Your Filter Needs to Be Cleaned or Replaced. Running The System Without Timely Filter Maintenance, Without Any Filter at All, Or with Poor Water Quality Will Quickly Lead to Clogged Nozzles
- Even With Proper Filtration, Some Clogging Is Normal Due to The Very Small Nozzle Openings. Nozzles Are Wear Items and Require Occasional Cleaning and Replacement.
Recommendations:
- Clean Filter Cartridge
- Clean Nozzles (Purchase Cleaning Solution Here)
- Replace The Standard Filter At Proper Intervals –
- Upgrade With An Additional Scale Filter
- Replace Nozzles
Nozzles Leaking:
- A Nozzle That Leaks After The System Is Turned Off Is Easily Fixable By Installing A Drain Valve. Simply Install This Drain Valve at The Beginning of Your Misting Line to Help Alleviate Any Excess Leaking on Your Misting Line.
Why Is My Pump Shutting Off?
If The Pump Is Hot from Operating, The Internal Thermal Safety Switch Prevents It from Turning on Until It Cools. Make Sure the Pump Has Had Time to Cool Off and Recheck the Operation.
This Feature Is Built into All Oil-Less Pumps by The Manufacturer to Protect the Motor and Extend Its Life. It Is Not a Defect—Once the Pump Temperature Drops Below the Safety Limit (Around 145°F), It Will Automatically Restart.
How to Reduce Overheating
- Cool The Pump While Running: Aim 1–2 Misting Nozzles Directly at The Pump.
- Add A Heat-Sink: Attachable Heat-Sinks Help Dissipate Heat More Effectively.
- Control Pump Speed: A Pump Speed Controller Lowers Rpms, Reducing Heat Buildup.
- Choose The Right Location: Keep the Pump in A Shaded, Well-Ventilated Area, Away from Direct Sunlight.
By Following These Steps, You Can Keep Your Pump Cooler, Reduce Shut-Offs, And Ensure Longer Service Life
