If not, switch the system ON and check for alarms and continue troubleshooting. Check Offsets. They should be at zero during normal operation or can be used to simulate FT and OT to create a Cooling demand. - Page 10 TROUBLESHOOTING PROBLEM POSSIBLE CAUSES POSSIBLE CORRECTIVE STEPS Reduce amount of water delivered to the nozzles. Refer to the Operation Principle/Sequence of Operation section of the adiabatic controller programming manual to understand your configuration and adjust the amount of water by following Great amount of water is dropping Too much water to the instructions on page 17 to page 19.
- Page 11 TROUBLESHOOTING PROBLEM POSSIBLE CAUSES POSSIBLE CORRECTIVE STEPS If using city water, make sure pump inlet pressure is at least 40 psi. Make sure there is no restriction and inlet pipe dimension is respected according to the information supplied previously in this manual. Low-pressure switch may be damaged. Check low-pressure switch.
