Technical specifications:
Flow pressure (min. – max.): 1,0 - 5,0 bar
Static pressure max.: 8 bar
Flow volume at 3 bar: 15 l/min
Operating temperature max.: 70 °C (
Thermal disinfection max. 80 °C - 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 shower fittings are suitable for use in drinking water systems in accordance with the current German Drinking Water Ordinance.
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. 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. All products from SCHELL can
be used with all potable waters in accordance with the EU Drinking Water Directive. Applicable national regulations about general partial
water softening for drinking water must be observed.
General assembly information:
Use corrosion-resistant pipe materials. Seal threads with permitted sealants only. 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 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. Check the temperature setting of the thermostat, hot water safety device
(38 °C ± 1 °K). Important! Ensure that all pipe routes up to the building fitting connections are also printed clearly: this enables a proper
pressure test to be performed even when isolating valves, solenoid valves or SC cartridges are also closed.
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.
