Mains water supply (connection to a water tap)
An enclosure inside the unit contains the connection kit for mains water and waste water. Install the
mains water connection using either the enclosed water hose or another pressure-resistant (> 10 bar)
one. The water hose must be heat resistant up to 95 °C. Secure the connection with a hose clamp.
Before switching on the unit, check the connection for leaks.
As the appliance only lets in water when required, there is no continuous water flow.
In order to guarantee perfect humidifying, observe the following points with regard to
the water supply:
•
Supply pressure 1 to 10 bar
•
Water type: Tap water with conductivity of 200 µS/cm to 500 µS/cm (tolerance range
100 µS/cm to 800 µS/cm).
Test: Let boil at least 1 litre of tap water in a suitable pot for 10 minutes in order to
precipitate the temporary hardness; then measure the conductivity in the upper half of the
volume.
If the conductivity is between 100 µS/cm and 200 µS/cm large electrodes (DC-5005-0056)
have to be installed.
If the conductivity is between 500 µS/cm and 800 µS/cm an electrode separating plate (DC-
6002-0088) has to be installed between the small electrodes.
If the conductivity outside of the range of 100 µS/cm to 800 µS/cm contact your local
Datacolor service representative.
•
Total hardness 28.4 mg Ca/l up to 56.8 mg Ca/l.
In this range of hardness the conductivity is normally between 200 µS/cm and 500 µS/cm.
In cases of lower hardness the conductivity is normally too low. In cases of higher hardness
the conductivity may be too high. Furthermore the steam generator calcifies faster and
more frequent service intervals are necessary.
But in all cases the conductivity has to be measured as described before. It is possible that
the conductivity is in the range of 200 µS/cm and 500 µS/cm and the unit can be operated
although the hardness differs.
•
Amount of chloride in the water: <100 mg/l
High amounts of chloride and free chlorine, e.g. from water disinfection, causes strong
abrasion of the electrodes.
•
Do NOT use softened water (soft water, distilled water, fully desalted water).
•
Water intake temperature NOT below +5 °C.
•
The mains water intake should be provided with a shut-off slide or water-tap.
•
For the water supply, fix the delivered adapter on the thread of the mains water connection
(H) at the rear of the chamber and put on the hose
•
Protect both the fresh water and the waste water supply at both sides by the delivered hose
clamps.
