corrosion according to VDI 2035); fix leaky spots.
▪ Commercially available corrosion protection agents
(underdosing due to consumption!).
▪ Commercially available combination products
formers.
▪ Commercially available cooling brines
WARNING
Personal injury and material damage caused by impermissible fluids!
Impermissible fluids can damage the pump and also cause personal injury.
1)
Add additives to the fluid on the pressure side of the pump, even if this is contrary to
the recommendations of the additive manufacturer.
▪ Use only branded products with corrosion protection inhibitors!
▪ 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 corrosive and can dam-
age 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 re-
moved 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 due to fluids not approved for drinking water!
Because of the materials used, pumps of the Stratos MAXO/ -D series are unsuitable
for use in applications involving drinking water or foodstuffs.
The smart-pumps of the Stratos MAXO-Z series are specially adapted to the operating
conditions in domestic hot water circulation systems through the selection of materials
and their design, taking into account the guidelines of the German Environment Agency
(UBA):
▪ Drinking water acc. to EC Drinking Water Directive.
▪ Clean, non-aggressive, low-viscosity fluids in accordance with national drinking water
provisions.
