Electric Coil Cleaner System

Frequently Asked Questions

• The motor continues to run even though the trigger is released.

  The unit was turned on while in garden hose mode and the garden hose was not connected to the machine. Hook up a garden hose to prime that side first. Then re-prime the tank side.

• Soap and water is not mixing. I turn the mixing value from one end to the other and in between only water coming out.

  • The coil cleaning solution tank is empty, and therefore not mixing any cleaner into the water spray. Check the tank to make sure it’s full.
  • There is a blockage in the mixing tank. Check inside the tank to make sure there is nothing caught in the drain area. You can also remove the base to see of an obstruction exists in the drain lines.
  • The mixing valve stem has been stripped. This effectively renders the mixing valve “stuck” in a single position – in this case at zero. Contact us for support and replacement of the valve.
  • A caustic coil cleaner was used and the acid has eaten at the mixing valve. Contact us for support and replacement of the valve.

  As a reminder, the CoilJet is designed for optimal use with alkaline coil cleaners. Caustic coils cleaners will degrade internal parts. If a caustic coil cleaner is required for use, make sure to remove all the cleaner after use and throughly flush the unit. Fill the cleaner tank with water, open the valve and empty the tank of water.

• The cleaner leaks into the water tank. Is there a fix?

  There may be a variety of causes that may be in play here from a cracked tank to a stripped or faulty chemical mixing valve. Please contact us at 800-995-2222.

• I can't seem to get any decent pressure out of it. I've tried priming the pump but after 15 minutes or so it's still just trickling out. Does it take a long time to prime the pump? Is there an in line filter anywhere that could be clogged?

  No, the pump should come to pressure within seconds. Generally this means there’s a clog in the system or pump issue. Please call us at 800-995-2222 to walk through some diagnostics.

• My CoilJet doesn't power on. What could be causing this?

  There are a few reasons this may be happening. We recommend taking the following steps to identify any potential cause.

  Check for blown fuse. Your CoilJet includes a 15amp fuse located in the base of the unit. Under special conditions, this fuse may blow to protect other components. To locate the fuse remove the six screws on the bottom cover of the unit. Locate the yellow fuse holder and check its condition. Replace the fuse with a standard in-line 15 amp fuse.

  Check for loose or damaged wiring. In extreme cases, wiring can become loose or damaged, either through shock/vibration or accidental chemical spills. With the base cover still off, check for this condition. If you find loose or damaged wiring, please contact us at 800-995-2222.

• Can I use harsh chemicals or acids in the CoilJet?

  Not without eventually causing damage to the pump. If a chemical of this type is used in the CoilJet it is important flush the unit out with fresh water immediately afterwards. We recommend using SpeedyFoam from SpeedClean, an acid free coil cleaner delivers superior cleaning power without harmful effects to you and less harmful to the environment. Please refer to the CoilJet chemical compatibility chart in the downloads area of this support page for more information.

• I have a question about the coil cleaner I would like to use. In the manual it says not to use sodium or potassium hydroxide chemicals. What will happen if done, and will this happen over a short period of time or a very long one?

  Use of a coil cleaners that contain caustic agents such as sodium or potassium hydroxide may cause components withint he CoilJet to fail. These chemicals are highly caustic and tend to pit and eat away certain metallic components quickly. Most issues with caustic coil cleaners occur when these chemicals are left in the system for extended peirods of itme, however they may occur quicker. SpeedClean always recommends the use on non caustic and no acidic coil cleaners like our SpeedyFoam coil cleaner. They are better for the coils, safer for the operators and better for the environment.

• My fuse has blown. What type of fuse should I replace it with?

  The fuse should be replaced with a a 15A buss type fuse.
