E OUTLINE DESCRIPTION CFC-free circulating chiller in a L-shaped design for Heidolph rotary evaporators. A Heidolph rotary evaporator (22) and a Heidolph vacuum pump (23) can be fitted on the circulating chiller to save space (Heidolph Instruments or your local Heidolph Instruments dealer will be glad to provide more information about suitable models). The circulating chiller is equipped with an air-cooled refrigerating machine and a circulating pump.
E SAFETY INSTRUCTIONS Follow the applicable safety regulations for your laboratory! Be extremely careful when dealing with inflammable substances. Before you connect the unit to your power supply, make sure that the supply voltage is the same as that on the rating plate. Make sure the unit stands securely! The unit is not explosion-proof. Caution must therefore be exercised when using it near flammable and explosive substances. ASSEMBLY 1. Important Read the following instructions before switching on.
E For temperatures under +10 °C, anti-freeze must be added to the coolant water. Check the highest and lowest permissible temperature of the selected thermal fluid against your desired operating temperature range. For thermal fluids, please note the following: Maximum operating temperature: The flash point of the thermofluid used should be at least 5 K higher. Minimum operating temperature: The viscosity of the thermofluid increases at low temperatures. This impairs flow and reduces heat transfer.
E 7. Filling the cooling liquid Only an externally closed system can be connected to the rotary chiller. Shut off the discharge valve (20) (so that the slit is vertical). Fill the circulation cooler via the filler neck after removing the cover (1) up to approx. 1 cm below the max. mark on the filling level indicator (14). The rotary evaporator cooler is vented by turning on the cooling and pump on the ROTACOOL with the On/Off button (9).
E 9. Attaching the extension kit Attach the extension kit (15) to the right hand side of the platform (17). 10. Setting up the rotary evaporator Place the rotary evaporator (22) securely on circulating chiller's platform (17). 11. Setting up the vacuum pump Place the appropriate vacuum pump model (23) on the circulating chiller. The vacuum pump is placed with its rubber feet in special cups (5) on the top of the circulating chiller in order to prevent accidental slipping.
E ROUTINE CLEANING AND SERVICING The cooling air for the refrigerating machine is sucked in through the liquefier in the base of the housing (16). The liquefier should be cleaned from time to time. To do this, tip the discharged unit onto its back. The fins of the black liquefier can now be cleaned using a brush or vacuum cleaner. Never use pointed or sharp-edged tools for this purpose, however, make sure the fins of the liquefier are not damaged or deformed as this will impair air flow.
E TROUBLESHOOTING Have any work required on the electrical, electronic and refrigerating components performed only by suitably qualified professionals. In the case of a malfunction, the unit will display a flashing error message on the screen. During error message output, the unit will switch between displaying the error message and the actual value of the flow temperature.
