  1. Minimum cooling water flow is 100%.
  2. Power Consumption does not include external pumps or fan motors.
  3. Height does not include removable lifting lugs, but does include level bolts. Width/Depth does not include junction box or mounting plates.
  4. High pressure option uses tubing that has passed UL hydrostatic testing at 300 psig.
  5. Do not exceed 150 PSI (1034 kPa) in any fluid circuit.
  6. Specifications are based upon water in all fluid circuits and fouling factor of 0.0005 ft2hr°F/Btu.
  7. Density of Heat Medium is 60.47 lbs/ft3, Specific Heat 1.003 BTU/lbs°F (185°F).
  8. Electric field wiring must be made in accordance with local regulation and must be sized to provide less than 2% voltage drop.
  9. Noise level is measured in a free field at a point 1m away from the cabinet and 1.5m above ground level.
