) When using a water-glycol mixture containing up to 40 % glycol (or media with a viscosity different to that of pure water, the flow data for the pump must be adjusted accord-
ing to the higher viscosity of the flow media, regardless of the percentage of the viscous matter. Only use branded goods with corrosion protection-inhibitors, follow manufac-
turer's instructions.
