My water chiller runs for a minute and shuts off, wondering where to start troubleshooting

If the Hydrofarm ACTIVE AQUA AACH50 water chiller runs for a minute and then shuts off, follow these troubleshooting steps:

1. Check if the chiller is in protection mode: The unit may shut off and enter a 3-minute protection cycle. Wait 3 minutes to see if it restarts automatically.

2. Inspect the fan: Ensure the fan is working and the chiller is dissipating heat properly. If the fan is not working, return the unit to the place of purchase.

3. Verify the set temperature: Make sure the set temperature is lower than the water temperature. If not, reset the temperature.

4. Clean air inlets/outlets: Use a brush or vacuum cleaner to clean the air inlet and outlet if they are clogged.

5. Ensure proper installation: Confirm the unit is installed on a flat surface. Reinstall if necessary.

If these steps do not resolve the issue, return the unit for warranty assessment.

    INSTRUCTIONS INTRODUCTION Thank you for purchasing the Active Aqua Series Chiller. The chiller represents a significant step forward in horticultural chiller engineering, offering state of the art technology at highly competitive prices. With this chiller, water temperatures for reservoirs can be quickly and economically maintained.
  • Page 12 The inflow should connect the chiller to the appropriate sized submersible water pump, such as an Active Aqua Water Pump, in the proper sized reservoir (see attached performance curve chart). The outflow tube should hang freely in the reservoir to re-introduce the chilled water back into the holding tank. www.Hydrofarm.com...
  • Page 13: Operation

    INSTRUCTIONS NOTE: Please note that the filter (with the pump) must be located below the reservoir water level. If you wish to place the unit at the side of the reservoir, you must fill the filtration system with water before turning it on. OPERATION 1.

    5. Plug in the pump and allow it to run for at least 1 hour so that the projected solution contacts all of the internal components used in the chiller during operation. Unplug the pump and empty the reservoir solution. 6. Repeat steps 4 and 5 with clean water ONLY. www.Hydrofarm.com...
