operation (refer to Section 2, Safety Requirements).
The IDH is designed to heat Deionized Water in either single pass (trim) or
recirculation applications up to 100°C. Figure 4-1 shows approximate flow
capacity versus temperature rise per fluid pass.
Minimum Flow Rate: 2 LPM (0.53 gpm)
Minimum Pressure: 0.10 MPa (15 psig)
WARNING: Element temperatures capable of heating beyond to 250°C.
