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:
1. Flow pressure: 3 bar
2. Mixed water temperature: 38 °C
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. 5 and approx. 40 s via the adjusting screw. 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 Federal Environment Agency).
Protection against Legionella:
If there is a risk of high Legionella concentrations, provide fittings with solenoid valve (# 01 875 00 99) 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:
All pipes are to be flushed before commissioning according to the ZVSHK worksheet ('German Central Association for Sanitation, Heating
and Air Conditioning'), DIN 1988-2 and DIN 806-4. Each fitting must undergo a pressure test which should be conducted preferably with
compressed air.
Fittings with thermostat:
Check the temperature setting of the thermostat, hot water safety device (38 °C ± 1 °K).
Use SCHELL thermostat button with fixed position (order no. 01 810 06 99) for applications where the preset maximum temperature shall
not be altered. Thermostatic fittings are equipped with anti-scalding protection conforming to EN 1111.
Maintenance information:
In accordance with DIN 1988 the RV must undergo an annual function test. The function of the thermostats should be tested at
appropriate intervals by the operator. The filters should be cleaned and, if required, descaled as specified in DIN 1988 Part 8 (for drinking
water heaters) every 2 years.
Instructing the operator:
Instruct the operator in accordance with VDE 6023.
