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.

3.4 Assembly
WARNING: DO NOT use the refrigerated cooler with distilled or deionised water.
Use tap water or softened tap water. Using distilled or deionised water could corrode the cooling coil or
circulation pump.
Use anti-freeze if you intend you use the equipment at temperatures of +7ºC and lower. Only use tap water or
softened tap to water to dilute the anti-freeze DO NOT use distilled or deionised water.
3.4.1 Step 1
Pass the Tray drain hose through the 2 metal ttings as shown. Take care not to kink, twist or squash the hose.
3.4.2 Step 2
To get the best results we recommend you connect the recirculating cooler using exible hose of 9mm I.D. and
keep hose length as short as possible.Using longer hoses than necessary can result in poor performance and could
damage your equipment. You must use hoses that are suitable for your installation. Ensure hoses are sufciently
insulated for your installation.
Remove the Water in and Water out one touch connectors from the 90º elbows. To do this, press the Elbow collar
in and pull the One touch connector to remove.
