3.3 Connection to electrical power line
• According to the directions of VDE 0107 and VDE
0100, medically used rooms have to be equipped with
a leakage current protective circuit (FI protective circuit)
with a nominal leakage current of < 0.03 A. Installation
must correspond with VDE 0107.
• The ATMOS C 21 / C 31 is connected to a earthing
contact socket which is to be mounted near the unit
(max. 3 m, preferably on the left side, next to the function
column)(seeg.3).
• The current consumption of the ATMOS C 21 / C 31 is
maximum 5 A .
• For the connection of further electrical devices, please

in the water system.
Such a system is to be connected when the respective
drinking water is of hardness grade 3 (14 - 21°d resp. 2.5
- 3.8 mol/m³ = hard water) but especially with hardness
grade 4 (from 21°d resp. from 3.8 mol/m³ = very hard
water). You may receive information on the hardness
gradeofyourwaterfromthewatersupplyo󰀩ce.
Water drainage (option):
Prerequisites:
• PermanentlyinstalledconnectionttingwithG3/4"
external thread.
