(only for CTC 256 climatic test chambers)

Water specifications

For steam generation, use only:

►

Steam-distilled water (aqua dest)

►

Demineralised water (aqua dem) in accordance with VDE 0510/DIN EN 50272; regulations

must be strictly adhered to (production conductivity ≤ 10 μS/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.
