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 tted with thermal fuses.
Techne Baths
Techne manufacture a range of unheated baths from 8 to 48 litre capacity which can be tted with any of the
thermoregulators. The B-8, B-12, B-18, and B-26 bath inner containers are manufactured from stainless steel for
maximum corrosion resistance and are deep drawn with large easy clean corner radii. The B-48 inner is also manu-
factured 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) Techne 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, Techne offer a range of refrigerated baths of 7, 12 or 22 litre capacity. These have a built-in refrigeration
system for temperatures down to -35°C.

Safety and Installation
Introduction
Please read all the information in this booklet before using the unit.
Safety Advice
Techne have taken great care in the design of these units to protect operators from hazards, but operators should
pay attention to the following points:
v HIGH TEMPERATURES ARE DANGEROUS: they can cause serious burns to operators and ignite combustible material.
v USE CARE AND WEAR PROTECTIVE GLOVES TO PROTECT HANDS.
v DO NOT use combustible substances near hot objects.
v DO NOT operate the unit in the vicinity of ammable liquids or gases.
v NEVER lift or carry the unit until it has been switched off and allowed to cool for at least 30 minutes.
v The unit should be carried using both hands.
v NEVER move or carry the unit when in use or connected to the mains electricity supply.
v DO NOT position the unit so that it is difcult to disconnect from the mains supply using the mains plug.
v The mains outlet socket used should be located close to the equipment and readily identiable and
accessible to users.
Operator Safety
All operators of Techne equipment must have available the relevant literature needed to ensure their safety. It is im-
portant that only suitably trained personnel operate this equipment, in accordance with the instructions contained
in this manual and with general safety standards and procedures. If the equipment is used in a manner not specied
by Techne the protection provided by the equipment to the operator may be impaired.
All Techne units have been designed to conform to international safety requirements and are tted 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.
