Typical: 10 - 29°C (50° - 85°F)
Minimum: 2.1 barg (30 psig)
Maximum: 4.1 barg (60 psig)
0 ppm
For soft water [less than 1 grain per gallon
(gpg) or 17 mg/L hardness]
acceptable pH: 3.0 - 11.0
For unsoftened water (contact factory for
water analysis), acceptable pH: 5.0 - 6.0
For short-term (i.e., cleaning) acceptable
SDI range: 2 - 12
