My aqua active chiller will only display in Celsius. I held down the up down areas and I held down the set button, but it can’t make it go back to Fahrenheit.

To change the display from Celsius to Fahrenheit on the Active Aqua AACH10HP chiller, press and hold the ▲ (Increase) or ▼ (Decrease) button for 5 seconds while in Display mode.

The GFI to my active aqua AACH 25 HP keeps tripping it used to work for about a year and now it does not work. I had an electrician not only rewire the GFI to its own unit but also put in an entirely new GFI, however, it keeps tripping And I would like to know what the solution is to be able to fix this because it worked last year and I’m confused.

    The super silent design results in significantly lower noise levels. The Active Aqua Series Chillers have a strong chassis with an ABS plastic housing which is anti-rust and anti-corrosive, ensuring that the chiller does not look out of place in any setting. For a complete understanding of this chiller, we recommend reading this instruction manual thoroughly.

    INSTRUCTIONS TERMS AND SYMBOLS Several symbols are used in this manual and on the product itself which are aimed at promoting proper and safe operation in order to prevent personal injuries or damage to the chiller. Please familiarize yourself with the symbols below before reading the manual or trying to operate the chiller.
  • Page 12 The inflow should connect the chiller to an appropriately-sized submersible water pump such as an Active Aqua Submersible Pump in a reservoir of appropriate capacity (see attached performance curve chart). The outflow tube should hang freely in the reservoir to re- introduce the chilled water back into it.
