•Fullydesalinatedwater(deionised,demineralised,

•Ultrapurewaterwithaconductivityof<0.1µS/cm

Resistance against external corrosion

GeberitMapressStainlessSteelisresistanttocorrosion

IfGeberitMapressStainlessSteelisdirectlyconnected

takingthefollowingmeasures:

• Installationofdistancepieces(lengthL>50mm

• Installationofashut-offvalvemadeofnon-ferrous

heavymetals.

doesnotindicateanyriskofcorrosion.

WARNING

Risk of corrosion

Keep cutting tools and deburring tools free

from carbon steel chips when cutting Geberit

Mapress Stainless Steel

Do not use high-speed cutting wheels to cut

the pipe or fittings to length

Only use cutting tools that are suitable for

working with steel

Leaking press connection can be caused by

damaged seal ring

Deburr the outside and inside of the pipe ends

completely

Remove foreign bodies from the seal ring.

Do not tilt the pipe into the pressfitting.

Push the pressfitting onto the pipe, turning the

pipe slightly

Only use lubricants which are free from oil

and grease
