Dimensioning and protection of drinking water
Country-specific regulations and standards are generally
applicable here.
Water qualities
SCHELL fittings are suitable for use in drinking water
systems in accordance with the current German Drink-
ing Water Ordinance.
Depending on the system, there are sensitive parts
within the fittings that need to be protected against
dirt particles and limescale deposits. If necessary, back-
wash filters and decalcification systems are to be pro-
vided (water upwards of 10° dH). Approval is needed to
operate fittings with mineral waters where their con-
tents tend to flocculate, or which are particularly ag-
gressive towards metal materials.
All products from SCHELL can be used with all potable
waters in accordance with the EU Drinking Water Di-
rective. Applicable national regulations about general
partial water softening for drinking water must be ob-
served.
Installation instructions
Use corrosion resistant pipe materials. Only seal threads
with permitted sealants. Do not exceed standard
torque!
Rarely used fittings
Choose pipe routing that will not allow for stagnating
water to collect (ring installation). If necessary, provide
flush valves behind the fittings. If using after longer
periods of non-operation, let the water drain; see „Ger-
man Environmental Agency" (Umweltbundesamt) rec-
ommendation.
Protection against legionella
Country-specific regulations and standards are generally
applicable here. Take particular care with installations
for people with weak immune systems.
Instructions for commissioning
Country-specific regulations and standards are generally
applicable here.
Every fitting is to undergo a pressure test after installa-
tion; where possible, perform the pressure test with
compressed air.
Outdoor installation
WARNING: If there is a risk of frost, empty the fitting
and provide effective anti-freezing protection.
