CoilJet CJ-200E Support & Troubleshooting
Thanks for visiting the CoilJet CJ-200E support section. Here you will find answers to the most common support questions our customers have. Utilize the tabs to find the appropriate selection for your needs.
- 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 thoroughly flush the unit. Fill the cleaner tank with water, open the valve and empty the tank of water. If you have used a coil cleaner other than SpeedyFoam in your CoilJet please follow these instructions immediately after use.
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.
