  If your Swegon Chiller unit's display is on but the unit doesn't start, it could be due to a lack of 230V auxiliary power supply. First, verify that the secondary circuit of the 230V transformer is intact. Next, check that the protective devices downline of the 230V transformer are also intact. Finally, ensure that the phase sequence is correct and the phase sequence relay is working properly.

  If your Swegon Chiller unit doesn't start and the display is off, it could be due to several reasons related to power supply. Start by checking that the main disconnect switch is in the “ON” position. Then, check for voltage in the power supply line. Also, verify that there is voltage to the auxiliary circuit and that the protective devices upline and downline of the transformer of the auxiliary circuit are undamaged. If a protective device has triggered, reset it after addressing the cause.

Why are there abnormal noises coming from the hydraulic pipes of my Swegon BlueBox Zeta Rev Chiller?
- J
  Jenna Fisher MDAug 21, 2025
  Abnormal noises from the hydraulic pipes in your Swegon Chiller can be caused by a few issues. One potential cause is the system pump operating outside of its performance curve, leading to an excessive water flow rate. If you cannot adjust the pump's control, try partially closing the shut-off device on the delivery side of the unit until the nominal flow rate is restored. Another cause could be the presence of air in the system. Ensure that the air valves are not shut off and vent the system to remove any trapped air.

What does it mean if there is oil on the discharge of the safety valve of my Swegon BlueBox Zeta Rev?
- S
  Shirley PhillipsAug 25, 2025
  The presence of oil on the discharge of the safety valve of your Swegon Chiller may indicate that the valve opened because the protective devices failed. Check that the high pressure switches are working and replace them if necessary. The valve itself might need replacement. It can also indicate overtemperature, in this case you should replace the valve and restore the charge.

  Abnormal noises from your Swegon Chiller unit due to vibrations often occur because the unit's weight isn't evenly distributed on the base. Correct the weight distribution by adjusting the height of the anti-vibration mounts.

Why is my Swegon BlueBox Zeta Rev pump leaking water on its first startup?
- A
  Alejandra SimmonsSep 10, 2025
  If you notice water leaks from the pump of your Swegon Chiller during the first start-up, it's likely due to the mechanical seal bedding in. Pressurize the pump body two or three times by closing and opening the delivery valve to correctly bed in the seal.
