The diagram below gives a graphical account of the Orion medium chiller function Chiller enabled. Full cooling, by-pass valve off By-pass valve enabled Band of temperature where by-pass valve is active. Page 9 of 24 Orion 796 Iss.08 – 01/14...
The chiller is fully automated and requires no user intervention. Because of the complex nature of this refrigeration system, it is recommended that in the event of service, you contact Isotech for advice as it is generally beyond the scope of standard refrigeration systems. Chiller gases and quantities...
The cooling power control permits the power to be reduced from maximum and fine tuning of performance at different temperatures. Full clockwise is maximum cooling. Set the flow control to suit the liquid and operating temperature. Page 11 of 24 Orion 796 Iss.08 – 01/14...
When the SP.RAT is active the lower setpoint display will now automatically update with the current value, known as the working setpoint. The setpoint can be seen by pressing either the UP and DOWN key. The Setpoint ramp rate operates when the bath is heating and cooling. Page 13 of 24 Orion 796 Iss.08 – 01/14...
Indicates the refrigeration is in full cooling mode Units The units can be changed from °C. Press the scroll key until the lower displays shows UNITS Use the UP and DOWN keys to select the desired display unit. Page 14 of 24 Orion 796 Iss.08 – 01/14...

Connect the bath to the supply and switch on. Set the over temperature controller to a suitable value, see earlier. Set the set-point of the temperature controller to the desired value (50.0°C). Ensure correct operation of the bath. Page 17 of 24 Orion 796 Iss.08 – 01/14...
Other criteria also need to be met, such as safety, operating range and fume emission for example. Isotech is able to supply a number of fluids for various temperature ranges, refer to Solutions for Primary & Secondary Laboratories, Volume 1.
Clean the bath. Detergent and absorbent paper will assist. If the bath has been used with an oil, it can be helpful to re fill with water and detergent and to allow the mixture to circulate before draining again. Close the tap. Page 19 of 24 Orion 796 Iss.08 – 01/14...
Water passed through the coil will substantially reduce the cooling time. To avoid any hazard from the expansion of water to steam do not use water at temperatures in excess of 100°C and ensure water is drained from the coil before setting the Bath above 100°C.
