Distribution: Adequate, or adaptable to expansion? Confirm that noise level guarantees meet specifications. Many potential problems can exist. Here are some of them: • Start-up • Refrigerant migration • Thermal expansion • Shutdown: Have these been addressed? • A freeze situation • A solidification situation • A refrigeration migration problem • The need for control in cold weather Verify that, as installed, recirculation should not be a problem. 14)? • Do cumulative tolerances create a problem?

Have the heat exchanger engineer review rack layouts and flow areas before cables are manufactured to minimize future cooling problems. The cost of this requirement is small, but correction later will be costly. Designers should include the need in the specifications.
