▪Comply with the chloride content of the top-up water according to
the manufacturer’s instructions! Chloride containing soldering
pastes are not permitted!
▪Follow the safety data sheets and manufacturer’s instructions!
Salty fluids
CAUTION
Material damage due to salty fluids!
Salty fluids (e.g. carbonates, acetates or formates) are very cor-
rosive and can damage the pump!
▪Fluid temperatures above 40°C are not permitted for salty fluids!
▪Use a corrosion inhibitor and constantly check its concentration!
NOTICE
Use other fluids only after approval by WILO SE!
CAUTION
Material damage can occur due to the accumulation of
chemicals!
When changing, refilling or replenishing the fluid with additives,
there is a risk of material damage caused by the accumulation of
chemicals.
▪Rinse the pump separately and thoroughly. Ensure the old fluid has
been completely removed from the interior of the pump!
▪Remove pump before change in pressure flushes!
▪For chemical flushing measures:
– Remove the pump from the system for the duration of cleaning!
Drinking water pumps:
WARNING
Health hazard!
Because of the materials used, pumps of the Stratos
MAXO/ -D series are unsuitable for use in applica-
tions involving drinking water or foodstuffs.
The smart-pumps of the Stratos MAXO-Z series are coordinated
specifically for operating conditions in domestic hot water circula-
tion systems through a selection of materials and their design, tak-
ing account of the guidelines of the German Environmental Agency
(Umweltbundesamt):
▪Drinking water acc. to EC Drinking Water Directive.
