Note
• The tray may suffer damage as a result of corrosion and pitting, causing the temperature control
fl uid to infi ltrate the heating system. Only ever use demineralised water with a conductance level of
5-10 microsiemens and a pH value between 5 and 7.
• The tray may suffer damage if ultrapure water or DI water with an electrical conductance level
of below 5 microsiemens is used. Only ever use pretreated water with a conductance level of 5-10
microsiemens.
• When fi lling the bath, make sure you stop when the liquid level is between the two fi ll level
marks on the right inside wall of the tray. Water baths may have a water level control feature (see
section 9).
