What to do if KKT Chiller refrigerating machine starts and stops short-termed?
If the KKT Chiller's refrigerating machine starts and stops frequently, ensure there is sufficient fresh air supply and removal, eliminating any short-circuit between fresh and exhaust air. If this doesn't resolve the issue, there may be a refrigerant leak. In that case, locate the leak, seal it, and refill the refrigerant circuit.
Why KKT Chiller has not enough refrigeration power?
If your KKT Chiller isn't providing enough refrigeration power, start by venting the system to remove any air in the water circuit. Also, ensure that the water pipe cross-section is correctly designed, and the check valve is fully open to maintain the minimum water agitation quantity. If the issue persists, check for adequate fresh air supply to the condenser. Finally, inspect the refrigerant circuit for leaks; if found, seal them and refill the circuit.
Why does KKT Chiller pump make gurgling noise?
If the pump in your KKT Chiller is making gurgling noises, it's likely that the circuit is not completely vented. To resolve this, vent the system and fill it up with water.
What to do if electrical heater in KKT KPC 108-L-U/S Chiller water circuit does not work?
If the electrical heater in the KKT Chiller's water circuit isn't working, manually reset the safety temperature limiter located under the heater cover, as it may break contact if the heating box exceeds 266°F (130°C). Check the water circuit pressure and ensure it is adequate. Also, verify the temperature controller parameters responsible for switching the heater are correctly configured. If there is a lack of water, address the cause and refill the circuit.
What to do if KKT KPC 108-L-U/S Chiller compressor stops?
If the compressor in your KKT Chiller stops, wait for it to cool down. Cleaning the condenser or improving fresh air supply may also help. If the issue continues, the Klixon may be defective and require replacement.
How to troubleshoot malfunction of pump in KKT KPC 108-L-U/S Chiller?
If the pump in your KKT Chiller is malfunctioning, ensure the main switch is on, and the control switch is set to 'AUTO'. Replace any defective main or control current fuses. If the pump motor is defective, replace it. Check the water quantity and system pressure, cleaning the strainer if necessary. If the “overheating water reset” lamp is lit, inspect the refrigerant circuit. Switch on the main switch.
What to do if KKT KPC 108-L-U/S Chiller still has malfunction of refrigerating machine?
If the refrigerating machine still malfunctions in your KKT Chiller, and there's low pressure in the refrigerant circuit, it may be losing refrigerant. Find the leak, seal it, and refill the circuit. Other potential issues include a dirty dryer, a defective pressure relief valve, or a defective solenoid valve in the liquid pipe, all of which should be replaced if faulty. High pressure in the refrigerant circuit could be due to a dirty condenser, a defective fan, high outside temperature, or a defective condenser control pressostat. Clean the condenser, ensure the electrical cause is correct by checking the fuses, spray the condenser with water, or replace the pressostat as needed.
