Technical specifications:
Flow pressure (min. – max.): 1,0 - 5,0 bar
Flow rate (recommended): 0,15 l/s (9l/min)
Flow rate: (min. – max.): 0,1 - 0,3 l/s (run times change)
Temperature: 10 °C - 45 °C (risk of scalding)
Temperature max.: 70 °C (short-term, e.g. for thermal disinfection - ATTENTION: Risk of scalding!)
Installation information:
Ensure adequate dimensioning in accordance with DIN 1988 Part 3, or EN 806-3. Observe DIN 1988 Part 4 (protection of drinking water,
compliance with drinking water quality) as well as EN 1717 (protection of drinking water against contaminants in drinking water supply
installations).
Water qualities:
SCHELL wall-mounted basin fittings are fit to be used in drinking water systems in accordance with the Trinkwasserverordnung <Drinking
Water Ordinance> 2001. It is inherent in the system that the fittings contain sensitive modules which must be protected against dirt particles
and calcification. If required, provide return flush filters and decalcification systems (water from 10 ° dH). Fittings must not be operated with
mineral water whose contents have a tendency to flocculate or which are especially aggressive towards metallic materials until it has been
released.
General assembly information:
Use corrosion-resistant pipe materials. Seal threads with permitted sealants only (Teflon tape). Do not exceed normal torques!
Rarely used fittings:
Select a pipe layout which prevents stagnant water (ring installation). If required, fit flush valves behind the fittings. If used after prolonged
operating pauses, allow water to drain (see recommendation of the Umweltbundesamt (Federal Environment Agency).
Protection against Legionella:
If there is a risk of high Legionella concentrations, take measures in accordance with DVGW work sheet W 551.
Pay particular attention to installations for persons with immune deficiencies.
Start-up information:
Schell shower fittings are tested with perfectly hygienic water (Legionella filter). Following installation, each fitting must undergo a pressure
test which should be conducted preferably with compressed air. Check the temperature setting of the thermostat, hot water safety device
(38 °C ± 1 °K).
Fittings with temperature limit:
ATTENTION: No scald protection, temperature mix ratio changes at higher hot water temperatures. If required, fit central thermostats.
Fittings vor premixed water:
To prevent the risk of scalding, select appropriate operating temperatures for the hot water supply. If required, fit central thermostats.
External installation:
ATTENTION: If there is a risk of frost, drain fittings, remove functional components or permanently protect fittings with thermal tape.
Information refers to for self-closing fittings WB-SC-M und WB-SC-V only:
All fittings have been tested for function at the factory and set for a run time of approx. 15 – 20 s at the following values:
1.
Flow pressure: 3 bar
2.
Mix water temperature: 38 °C
3.
Shower head flow rate: 10 l/min
Other pressures, flow rates and temperature changes will result in different run times:
1. Run time changes caused by flow pressure changes
Higher pressure – shorter run time
Lower pressure – longer run time
2. Run time changes caused by different flow rates
Lower flow rate – shorter run time
Higher flow rate – longer run time
3. Run time changes caused by temperature changes
Lower temperature – longer run time
Higher temperature – shorter run time
The run time can be set to a flow pressure of 3 bar between
approx. 5 and approx. 20 s via the regulating needle. Run time fluctuations
resulting from pressure fluctuations within the mains supply are normal.
