Assembly instructions
All fittings have been tested for function at the factory and set for a run time of approx. 20 – 25 s at the following values:
GB
1. Flow pressure: 3 bar
2. Mixed water temperature: 38 °C (locking disc)
3. Flow rate shower head: 10 l/min
Pressure changes, run time changes and temperature changes cause different running 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. 10 and approx. 30 s via the regulating needle. Run time fluctuations
resulting from pressure fluctuations within the mains supply are normal.
Rarely used 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 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.
Fittings with thermostat:
ATTENTION: Hot water temperatures which jump over the temperature barrier may result in scalds. If there is a risk of non-observance (child-
ren, etc.), install locking disc, enclosed.
Maintenance information:
In accordance with DIN EN 806-5 the backflowpreventer must undergo an annual function test. The function of the thermostats should be tes-
ted at appropriate intervals by the operator. The filters should be cleaned and, if required, descaled as specified in DIN EN 806-5 (for drinking
water heaters) every 2 years.
Instructing the operator:
Instruct the operator in accordance with VDI 6023.
