Installation Instructions

Mount the fan above the Grandmeister blowing in across the top of the amp. Connect the power supply to the fan panel with the mating plugs. Connect the power supply to AC power. The power supply accepts from 100 to 240VAC.

To mount the rack ears on the Grandmeister or Tubemeister remove the specified screws shown on the instruction sheet. Install rack mounts using the same screws.

Operating Instructions

Power the fan on. Power on the Grandmeister. Crank it up. Play hard!

Care and Maintenance

To maintain optimal performance, keep the fans clean. Canned air works well. If the fans are used outdoors or in a dusty environment is recommended to clean the fan blades as needed to keep clean.

Troubleshooting

The fan will not start:

1. Check the power connections.
2. Is the light on the power switch on? If not check power. If on and the fans are not spinning see #3.
3. Turn the fan blade by hand to see if they are stuck. They should be free moving. If this starts the fan it is likely the fans need maintenance.

The fan is making noise:

1. Check for anything that could be rubbing against the fan blade.
2. Make sure the fan blades are clean. Dirty fan blades can make noise.

If the above steps do not solve the problem, contact our friendly customer service for assistance.

Superb silent fan and my GrandMeister stays cool in the flight case. It also looks cool. Shipping to Netherlands worked out great. 5 stars!!!!

Received my fan and rack mounts in 2 days! I got the mounts for my TubeMeister 36 and they fit perfectly and very easy to install. I mounted the fan in my rack just above the TubeMeister as instructed and it works great! The whole rack stays cool. The blue lights match the TubeMeister perfectly and look very cool. So far I've gotten many compliments on my new set up. Thanks Hughes & Kettner and Procool for making great stuff!!! Can I give 10 stars?

Response from Procool:

Thank you for the great review! Yes, you can leave 10 stars. + On behalf of Hughes & Kettner we thank you for your business!
