What to do if my HANLI Chiller has compressor overload?
If your HANLI Chiller's compressor is experiencing overload, it could be due to a few reasons. The condenser might be dirty and clogged, requiring cleaning. There could be a fluorine leakage, so check for leaks. The air inlet and outlet may be blocked, so clear any debris. Finally, the ring temperature may be too high, so ensure the equipment is in a well-ventilated area.
What to do if HANLI HL-2000 displays Compressors Pressure failure?
If your HANLI Chiller is showing a 'Compressors Pressure failure', there might be several reasons. First, check for poor ventilation and clear any obstructions around the unit. Second, a refrigerant leak could be the cause, so check for leaks. Third, make sure the condensing fan is running; if not, inspect the fan. Fourth, too much dust in the filter can cause this issue, so clean the dust. Lastly, a damaged pressure switch could be the culprit, so check for loose pressure switches and wiring.
Why my HANLI Chiller displays Room temperature water High temperature alarms?
If your HANLI Chiller is experiencing Room temperature water High temperature alarms, it could be due to insufficient water flow. Check if there is a return of water at room temperature and if the water circuit is blocked. Another possible cause is poor ventilation, so clear the surrounding clutter.
What causes Phase sequence alarms on HANLI HL-2000?
If your HANLI Chiller is showing Phase sequence alarms, it could be due to a few reasons. It might be a power supply issue, such as being out of phase. In this case, you should check the power supply. Another cause could be a phase sequence error, which can be resolved by arbitrarily pairing two phase lines. Three-phase unbalance could also trigger this alarm, requiring a check of the power supply circuit. Lastly, a damaged phase sequence protector could be the reason, and in that case, you should replace the phase sequence protector.
Why is my HANLI Chiller showing Low temperature water High temperature alarms?
If your HANLI Chiller is experiencing Low temperature water High temperature alarms, it may be due to insufficient water flow, so testing the water supply line is recommended. Poor ventilation could also be the cause, so clear the surrounding clutter. Additionally, too much dust can lead to this problem, so clean the dust from the condenser.
What to do if HANLI HL-2000 Chiller displays Room temperature water Flow alarms?
If your HANLI Chiller displays Room temperature water Flow alarms, it might be due to a clogged normal temperature water line, so testing the cutting head for backwater is recommended. It could also be due to reversed inlet and outlet connections, so check the inlet and outlet lines. Leakage in the ambient water line can also cause this, so check and tighten water line connections. Finally, a damaged flow switch could be the issue, so replace the flow switch.
How to fix Low temperature water Flow alarms on HANLI HL-2000?
If you're getting a Low temperature water Flow alarms on your HANLI Chiller, there are a few potential causes. First, the low temperature water line might be blocked, so you should clean the lines. Second, the inlet and outlet connections might be reversed, so check those lines. Third, a leaky suction line could be the problem, so check and tighten the water suction line. Finally, the flow switch might be damaged, so check and replace it if necessary.
What does Room temperature water Low temperature alarm mean on HANLI HL-2000 Chiller?
If your HANLI Chiller displays a 'Room temperature water Low temperature alarm', it indicates that the water temperature of the equipment is low. In this case, check the relay for adhesion.
What does Low temperature water Low temperature alarm mean on HANLI Chiller?
If your HANLI Chiller displays a 'Low temperature water Low temperature alarm', it indicates that the water temperature of the equipment is low. In this case, check the relay for adhesion.
What causes Room temperature water Probe failure in HANLI Chiller?
If your HANLI Chiller is showing a Room temperature water Probe failure, it could be due to a short circuit or broken wire in the ambient water probe, so inspect the probe terminals and connections. Alternatively, the ambient water probe might be damaged, requiring a replacement probe.
