Why won't my ATS CyberChiller unit start?
If your ATS Chiller unit fails to start, it could be due to several reasons: * Incorrect phasing or voltage. In this case, correct the phase or voltage input. * Power failure. Check the power source, power inlet, and fuses. * Overload protection tripped. Identify the cause of the overload and reset the circuit breaker(s) or motor starter(s).
What to do if my ATS CyberChiller Chiller compressor fails to start?
If your ATS Chiller compressor fails to start, there could be several reasons: * The temperature setpoint may be too high. Adjust it to the desired temperature. * The compressor internal protector might be open. Check the compressor for a short circuit or ground. * There could be a complete loss of refrigerant charge, activating the low-pressure safety switch. Locate and repair the leak, then recharge the system. * The condenser pressure may be too high, activating the high-pressure safety switch. Check the condenser for obstructions. * The minimum off time may not have expired. Wait for the time to expire.
Why is the head pressure too high in my ATS Chiller?
High head pressure in your ATS Chiller can be caused by: * Low condenser airflow, indicated by excessively warm air leaving the condenser fan. Open air passages, clean the coil, and check the condenser fan(s). * Air or other non-condensible gas in the system. Recover the system and recharge it. * An overcharge of refrigerant. Reclaim excess refrigerant from the system. * Condenser/drycooler fans not operating. Check the main voltage power source to the unit.
Why is the condenser pressure too high on my ATS CyberChiller?
High condenser pressure in your ATS Chiller can stem from: * Non-condensable gas or air in the system. Recover the system and recharge. * A blocked condenser air intake. Remove debris and clean the condenser. * An overcharge of refrigerant. Reclaim excess refrigerant from the system. * A condenser fan not operating. Check the pressure/temperature operating switches and motor. Replace as needed. * A condenser pressure regulating valve setting that is too high. Adjust to obtain the correct pressure.
What causes low suction pressure in my ATS CyberChiller?
Low suction pressure in your ATS Chiller can result from: * Loss of refrigerant, indicated by bubbles in the sight glass. Locate and repair the leak, then recharge the system. * An expansion valve stuck in the open position, indicated by an abnormally cold suction line. Repair or replace the valve. * Low charge, flash gas in the liquid line, indicated by bubbles in the sight glass. Repair the leak and recharge the system. * A clogged drier/strainer, which feels cool to the touch. Replace the drier/strainer. * An obstructed expansion valve, indicated by a loss of capacity. Replace the valve. * Loss of control fluid from the expansion valve control head, indicated by bubbles in the sight glass. Replace the valve or control head.
Why is my ATS CyberChiller Chiller compressor so noisy?
A noisy compressor in your ATS Chiller can be due to: * An expansion valve stuck in the open position, leading to an abnormally cold suction line. Ensure the feeder bulb is tight on the suction line and check operation and superheat. * A broken compressor valve, indicated by compressor knocking and suction pressure rising faster than 2 lbs/min after shutdown. Replace the compressor. * Worn or scarred compressor bearings. Replace the compressor. * Liquid slugging. The system may be overcharged, so reclaim excess refrigerant. * A scroll compressor not properly phased. Correct the phase at the main power source, but do not rewire the compressor.
What causes the pump to fail to start on my ATS CyberChiller?
If your ATS Chiller pump fails to start, it could be due to: * Power failure. Check the main voltage power source input cable. * The control transformer circuit breaker tripped. Check for a short circuit or ground fault; if none, reset the circuit breaker. * A defective contactor. Repair or replace it. * The motor starter protector tripped. Reset the motor starter protector and check the amperage of the motor. Compare to the setting on the motor circuit controller and adjust to FLA.
Why does the evaporator coil ice up on my ATS Chiller?
If the evaporator coil ices up on your ATS Chiller, it could be due to: * Temperature setting too low. Increase the temperature setpoint. * Low refrigerant charge. Find the leak, repair it, and recharge the system. * Low water flow rate. Increase the flow rate.
What causes low head pressure in my ATS Chiller?
Low head pressure in your ATS Chiller is often caused by a loss of refrigerant, indicated by bubbles in the sight glass. Repair the leak and recharge the system.
Why is my ATS Chiller system short of capacity?
If your ATS Chiller system is short of capacity, it could be due to: * Low refrigerant, indicated by bubbles in the sight glass. Check for leaks, repair, and recharge the system. * An expansion valve stuck or obstructed, leading to short cycling or continuous running. Remove the valve and clear the obstruction or replace the valve. * A clogged drier/strainer, which feels cold. Replace it with a new drier/strainer.
