Vogt reserves the right to change designs and specifications without notice.

(1) Refrigerant charge is for low side unit only. Additional refrigerant required for high side and piping.

(2) Compressor requirement is based on 70°F makeup water, 14°F suction temperature, 100°F condensing temperature, 70°F ambient, and 25 gal/cycle blowdown. Compressor rpm’s vary.

(3) FLA for 460 volt models is approximately 1/2 that of 230 volt models. Total FLA does not include cooling tower.

(4) Makeup water is maximum value. Actual usage may vary.
