What to do if my Swegon Chiller unit does not start and the display is off?
First, ensure the main disconnect switch is in the “ON” position. Also, check for voltage in the power supply line. Verify 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 is there oil on the discharge of the safety valve of my Swegon Chiller?
The valve may be opening due to the failure of protective devices or overtemperature. Check if the high pressure switches are working and replace them if necessary. The valve might need replacement. If the valve opened due to overtemperature, replace the valve and restore the charge.
What to do if my Swegon Chiller is making abnormal noises from the hydraulic pipes?
The issue might be due to the system pump operating outside its performance curve with an excessive water flow rate or the presence of air in the system. If you cannot adjust the pump control, partially close the shut-off device on the delivery side of the unit until the nominal flow rate is restored. Ensure that the air valves are not shut off by valves. Also, vent the system to remove any trapped air.
How to fix abnormal noises from Swegon Chiller unit due to vibrations?
The weight of the unit may not be evenly distributed on the base. Correct the weight distribution of the unit by adjusting the height of the anti-vibration mounts.
What to do if Swegon Chiller unit does not start, the display is on?
Check if there is 230V auxiliary power supply. Verify that the secondary circuit of the 230V transformer is intact and that the protective devices downline of the 230V transformer are also intact. Ensure that the phase sequence is correct and that the phase sequence relay is working correctly.
What to do if the display is off on my Swegon Chiller, but the unit is operating normally?
The display connection to the control might be disconnected, or the display itself may not be working. Try restoring the connection between the display and the control. If that doesn't work, replace the display.
What to do if my Swegon Chiller unit does not start, the display is off, but the control is powered correctly?
The unit might be switched off from the display, and the display could be disconnected or not working. Restore the connection of the display or replace it.
What to do if Swegon Chiller unit does not start, the display is off, the control is powered correctly but the LEDs are not flashing?
The control is not working, so replace the control.
