4. Turn the instrument power ON and incrementally heat the bath to
desired control temperature while monitoring the bath liquid level
carefully. The bath level must be 15-20 mm (approximately ½" to
¾") from the top of the jar at the control temperature. If it becomes
apparent that this liquid level will not be achieved, return the bath to
within 10°C of ambient, turn the instrument power
OFF and add or
remove liquid as necessary.
5. Repeat step four until you have attained the proper bath liquid level
at the desired control temperature.
CAUTION Different bath fluids expand at different rates. Do not overfill the bath!
WARNING Monitor the level of bath liquid closely when operating the CT-1000HT at
higher temperatures (135-200°C). The bath liquid will expand as the
temperature increases. The CT-1000HT bath jar is not designed to
contain liquid under pressure. If the bath is overfilled, liquid may over-
flow.
Draining the Bath
If it becomes necessary to drain the liquid from the bath:
• Obtain a suitable container to hold all of the liquid drained from the
bath (approximately 20-22 liters (4.5 - 5 gallons)).
• Check the bath temperature. The bath liquid should be at or near
ambient temperature.
• Insert a tube into the bath chamber from the top opening and siphon
the liquid from the bath into a container positioned lower than the
bath.
WARNING Always use a rubber bulb or similar device to apply suction to a tube
containing bath liquids.
