Please consult the SCHELL „General installation conditions" available at www.schell.eu -> Service/Downloads/Installa-
tion conditions apply.
Dimensioning and protection of drinking water
Make sure there is sufficient allowance for dimensions in
line with DIN 1988 section 300 and EN 806-3.
DIN 1988 section 100 (protection of drinking water;
preservation of drinking water quality) and EN 1717
(protection of drinking water against contaminants in
drinking water installations) are to be observed.
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
Provide fittings with integrated flush valve for thermal
disinfection where there is a risk of high concentrations
of legionella or take other measures conforming with
the DVGW (German association for gas and water)
worksheet W 551. Take particular care with installa-
tions for people with weak immune systems.
Instructions for commissioning
Prior to commissioning, all pipe lines are to be flushed in
accordance with the ZVSHK ('German Association for
Sanitation, Heating and Air Conditioning') worksheet,
DIN 1988-200 and DIN EN 806-4.
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.
Instructing the operator
Instruct the operator in accordance with VDI 6023.
Quick information for the electrician
Observe VDE 0100.
