Pressure and Temperature Log
A log of temperatures and pressures should be taken regularly . Periodically conduct a visual inspection of the chiller to identify problems before
they reach the point of failure . As with any mechanical system, it is necessary to conduct a series of checks to the ClimaCool chiller to confirm
correct operation .
Weekly
• Review daily log from previous week
• Perform visual inspection
• Properly document all data taken
• Note any problems that may exist . Immediately plan for further
investigation . If repair is necessary, schedule for earliest possible
date .
Monthly
Extract a water sample from the evaporator . Confirm that the sample
bottle is filled to the top leaving no air in the bottle . Sample to be
tested and kept in compliance with the water quality parameters
listed in Table 1 on the water treatment page of this manual . NOTE:
Monthly records of compliance and testing are required throughout
the warranty period for warranty .
Quarterly
• Check controller operating parameters and set points
• Check refrigerant pressures and temperatures
• Check compressor amps
• Check compressor oil level
• Check and test all safeties
• Check water flow rates and pressure drops across evaporator and
condenser
• Properly document all data taken
Annual
• Isolate chiller, drain all water circuits
• Back flush all heat exchangers (use only ClimaCool
recommended de-scalers)
• Remove and clean all waterside strainers
• Perform leak test on all refrigerant circuits
• Check all interconnecting flanges for proper tightness
• Perform oil analysis on each compressor
• Check and test all refrigerant safeties for proper operation
• Check all electrical terminal connections for tightness
• Manually operate all waterside isolation valves on each module
• Check all peripheral systems for proper operation
• Check and test main controller
• Verify set points, sensors and general configuration
• Properly document all data taken
Recommended Maintenance Schedule
Daily
• A daily operational log should be kept
• Perform visually inspection
• Record entering and leaving chilled water and condenser water
temperatures and pressures
• Note any problems that may exist . Immediately plan for further
investigation . If repair is necessary, schedule for earliest possible
date .
• Properly document all data taken
