Installation instructions
Technical specifications:
Flow pressure (min. – max.): 1,5 - 5,0 bar
Flow rate (recommended): 0,15 l/s (9l/min)
Flow rate: ≤ 15 I/min at 3 bar flow pressure
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 300, or EN 806-3. Observe DIN 1988 Part 100 (protection
of drinking water, compliance with drinking water quality) as well as EN 1717 (protection of drinking water against conta-
minants in drinking water supply installations).
Water qualities:
Schell shower 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, provide fittings with integrated flush valve (SCHELL LINUS D-E-T, D-E-T ECO,
D-C-T, BASIC D-C-T or D-SC-T) for thermal disinfection or take other 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. Prior to commissioning, all pipe lines are to be flushed
in accordance with the DIN EN 806-4.
Fittings with temperature limit:
ATTENTION: No scald protection, temperature mix ratio changes at higher hot water temperatures. If required, fit central
thermostats.
Mix water fittings without thermostat:
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.
