Water specifications
For steam generation, use only:
►
Steam-distilled water (aqua dest)
or
►
Demineralised water (aqua dem) in accordance with VDE 0510/DIN EN 50272; regulations
must be strictly adhered to (production conductivity
≤
10
μ
S/cm). Battery water in accord-
ance with VDE 0510 is available in larger chemist’s shops, super markets, hardware stores
and in the wholesale trade. The standard VDE 0510/DIN EN 50272 has to be explicitly
specified on the label.
Otherwise, possible calcification in the steam generators, steam piping and peristaltic pumps
could affect the operability of the device.
Use only water with a pH value of > 5 and < 7.
The CTC climatic test chamber is equipped with four tanks, each holding 10 litres; these are lo-
cated in the drawer at the front right (Fig. 14). The two rear tanks (A1 and A2) are used to col-
lect condensation water produced during operation. The two front tanks (B1 and B2) contain
fresh water, which the test chamber needs to humidify the interior. The TTC temperature test
chamber is equipped with just two condensation water tanks, and has no fresh water tank.
To fill the fresh water tank, pull the drawer out of the test chamber (Fig. 14). Press the attach-
ment clip on the tube connection and pull the tube connection upwards and off (Fig. 15). The
lid can be removed, the tank taken out and filled with fresh water. Then, twist the lid back
onto the tank and push on the tube connection until it clicks into place.
