Water quality
Lime deposits and corrosion residues in tap water can lead to the
GA231
following malfunctions:
● Premature clogging of the filters in the unit
● Rapid clogging of the fine water paths and jets in the treatment
instruments
For these reasons, the following points must be observed:
● Permitted water pressure: 2.5bar (36.25psi) to 6bar (87psi)
● Permitted minimum flow volume: 3l/min
● For water hardness (total hardness) of 2.2 mmol/l (= 12° dH ), install
water softeners.
Set the blend hardness to 1.4 mmol/l (= 8° dH).
● Install a conventional fine filter; fineness: > 80 µm (0.08 mm).
● Installation must be performed in compliance with the
recommendations of the national installation requirements (e.g. EN
1717/DIN 1988).
● The water quality must comply with the national requirements for
drinking water.
● The connection must be made to cold water.
● When laying the water pipe to the treatment center, comply with the
following instructions to reduce the quantity of micro-organisms in the
feed pipe:
– Avoid long stub lines to the treatment center.
– Carry out the installation so that, where possible, other main
consumers (such as the sink) are fed from the same line
downstream of the treatment center connection.
– Avoid laying the supply line parallel to hot water pipes.
● Before installation, an acceptable microbiological water quality
(drinking water) must be ensured and documented in the form of a
colony count.
● Sampling and the colony count must be performed by a competent
laboratory.
● The colony count must fulfill the national regulations for drinking
water and must not exceed 500 CFU/ml under any circumstances
(CFU: colony forming units).
● In the event of an increased colony count, the indoor installation must
be checked and the cause of contamination eliminated. Alternatively,
a stand-alone water supply can also be installed.
