NOTES:
1. Specifications
are based on water in all circuits and fouling factor of 0.0005 ft2hr°F/Btu.
2. Do not exceed 85.3 psi operating
pressure in any water circuit.
3. If heat medium inlet temperature exceeds 203°F the chiller/chiller-heater
will shutdown and require manual reset.
4. Optional cooling water crossover piping with 3 in. type "L"
copper connections available for WFC-SC20/SH20 and WFC-SC30/SH30.
5. Sound pressure noise level measured in a free field at a point
79 in. behind the chiller/chiller-heater and 59 in. above the ground.
