Section 1 - Introduction
Thank you for purchasing this Stuart product. To get the best performance from the equipment, and
for your own safety, please read these instructions carefully before use.
If the equipment is not used in the manner described in this manual and with accessories other than
those recommended by the manufacturer, the protection provided may be impaired.
1.1 General Description
A Recirculating Cooler offers a powerful cooling for an external device. By accurately controlling the temperature
of your cooling medium down to -20°C, efciency of operations such as condensing can be greatly improved. A
recirculating cooler is not only much more powerful than conventional water cooling, but is also an ideal
alternative when water consumption is an issue for economical, environmental or practical reasons.
The SRC5 provides a powerful cooler with a compact footprint suitable for mounting on or under a bench. The LED
digital display clearly shows the current temperature of the cooling medium to ±2°C, while the set temperature is
revealed by a one button press.
The unit has a dedicated drain for easy emptying and cleaning. It also incorporates a built in safety alarm to indicate
an overload relay for the refrigeration unit. A dust lter is incorporated and can be accessed without tools via the
hinged front panel.
