For all models, bath temperature is monitored and controlled by a PRT in conjunction with a 3 term controller.
Protection in all the units is provided by means of an adjustable over-temperature cut-out. The pump motor and the
transformer are also fitted with thermal fuses.
Cole-Parmer Baths
Cole-Parmer manufacture a range of unheated baths from 8 to 48 litre capacity which can be fitted with any of the
thermoregulators. The WBU-200-8l, WBU-200-12l, WBU-200-8l, and WBU-200-26l bath inner containers are man-
ufactured from stainless steel for maximum corrosion resistance and are deep drawn with large easy clean corner
radii. The WBU-200-48l inner is also manufactured from stainless steel but is of welded construction. These baths
are suitable for use up to 200°C.
For higher temperatures (up to a maximum of 250°C) Cole-Parmer has a range of liquid calibration baths of
capacities 5, 7 or 12 litres. These baths are fully insulated providing excellent temperature retention and stability and
are ideal for calibration purposes.
In addition, Cole-Parmer offer a range of refrigerated baths of 7, 12 or 22 litre capacity. These have a built-in refrig-
eration system for temperatures down to -35°C.

USE CARE AND WEAR PROTECTIVE GLOVES TO PROTECT HANDS.
❖
DO NOT use combustible substances near hot objects.
❖
DO NOT operate the unit in the vicinity of flammable liquids or gases.
❖
NEVER lift or carry the unit until it has been switched off and allowed to cool for at least 30 minutes.
❖
The unit should be carried using both hands.
❖
NEVER move or carry the unit when in use or connected to the mains electricity supply.
❖

accessible to users.
Operator Safety
All operators of Cole-Parmer equipment must have available the relevant literature needed to ensure their safety. It
is important that only suitably trained personnel operate this equipment, in accordance with the instructions con-
tained in this manual and with general safety standards and procedures. If the equipment is used in a manner not
specified by Cole-Parmer the protection provided by the equipment to the operator may be impaired.
All Cole-Parmer units have been designed to conform to international safety requirements and are fitted with an
over-temperature cut-out. On some models, the cut-out is adjustable and should be set to suit the application. On
all other models the cut-out is pre-set to protect the unit.
If a safety problem should be encountered, switch off at the mains socket and remove the plug from the supply.
