  1. Minimum cooling water flow is 100%.
  2. Power consumption does not include external pumps or motors.
  3. Height does not include removable lifting lugs but does include level bolts. Width/Depth does not include the junction box or mounting plates.
  4. specifications are based on water in all circuits and a fouling factor of 0.0005 ft2hr°F/BTU.
  5. If heat medium temperature exceeds 204.8°F (96°C), the chiller or chiller/heater will shut down and require manual reset.
  6. Do not exceed 85.3 PSI (588 kPa) in any operating circuit unless the high pressure option is chosen. High pressure option allows 113.9 PSI (785 kPa) in the Chilled/Hot Water and Cooling Water circuits only. There is no high pressure option for the Heat Medium circuit.
  7. Noise level is measured in a free field at a points 1m away from the cabinet and 1.5m above ground level.
