START UP
Prior to Start-up Check List
• Is the case connected to its proper nameplate power supply?
• Is there power on at the breaker panel?
• Are the water hand valves open?
• Is the chiller on and circulating water through the condenser(s)?
• Are there any leaks from condenser water connections? Clamps may need to be tightened.
• Do evaporator fans rotate freely? Are they plugged in?
• Is the water strainer clear of debris?
Possible hazardous condition. Follow safety
procedures outlined by store safety management.
Starting up the case
• Ensure the chilled water flow is on, and connect the case to power.
The case(s) will start automatically within 4 minutes. The controller will be activated and the case
will begin to cool down.
NOTE: Compressor startups are staggered to prevent high electrical circuit demand.
Once the cases are running, listen for any unusual sounds or events. Examples include: evaporator
fan blade interference. Compressors should run continuously at startup. Use an amperage meter to
check the current to each compressor. Compressors are hermetic and very quiet.
