* Minimum cooling water flow

Notes:
  1. Fuel input is based on HIGHER HEATING VALUE of gas.
  2. Specifications are based on water in all circuits and fouling factor of 0.0005 ft2hr.°F/Btu.
  3. Do not exceed 114 psi operating pressure in any water circuit.
  4. Chilled/hot water flow limits are 80~120% of standard rating.
  5. Cooling water flow limits are 100~120% of standard rating.
  6. Two or more modules may be installed in parallel for larger capacities.
  7. Standard natural gas supply pressure is 7.0 in. wc.
  8. Sound pressure noise level measured in a free field at a point 39 in. in front of the chiller-heater and 59 in. above the ground.
