3.2 Electrical data
3.3 Input/output data
The pump offers various input and output options, depending on control variant.
3.4 Approvals
*
NSF61 is only valid for DME 375 and DME 940 standard range (without spring loaded valves).
Certification is based upon a dose rate that yields a sodium hydroxide (NaOH) concentration in potable
water that does not exceed 200 mg/L.
Certification is based upon a dose rate that yields a sodium hypochlorite (NaOCl) concentration in potable
water that does not exceed 84 mg/L.
Certification of this product has been performed to the health effects requirements of NSF/ANSI Standard
61, which assesses the acceptability of potential extractants from the chemical pump. No evaluation has
been performed on the strength or efficacy of the chemical fed. The specified chemicals are not certified by
UL to NSF/ANSI Standard 60, so the operation, maintenance and the consistency of the source ingredients
may affect the performance of the dosing pump.
