Filling and air purging an externally closed system 66 Caution! - Fill to the unit to the minimum level necessary. - Please refer to local regulations and internal procedures. - When filling the unit, extra precautions such as earthing the expansion tank, fluid container funnel and application may be necessary. - Personal Protection Equipment (PPE) should be worn as required by the fluid MSDS sheets, and local regulation. - Please note the temperature of the thermal fluid. The fluid should be left at room temperature for a few minutes before draining. Warning! Overflowing thermal fluid will create a film on surfaces, which should be cleaned up and properly disposed of as soon as possible in accordance with the MSDS information. If thermal fluid is spilled over the unit, the unit should be immediately turned off, and Huber-trained personnel consulted. Failure to observe the above precautions may mean that the unit will not comply with all of the requirements of DIN EN 61010-2-010. Filling - Lift the bath lid / cover from the bath / inlet nozzles - Carefully pour a suitable thermal fluid into the expansion tank, filling hole with help of appropriate accessories such as a funnel and / or beaker. The thermal fluid flows via the expansion tank into the machine, then through the hoses into the external application. - Start the filling process by selecting the Main menu point start&stop. Continue by pressing the sub menu point start air purge. The filling process is finished when the bath is filled sufficiently (for devices with heating, heating coils have to be beneath the thermal fluid level, corresponds to minimum bath level / minimum filling) and no air bubbles should remain in the application (e.g. double jacketed reactor) The controller monitors the filling level and a corresponding message will be displayed in the graphic display. - Let the Air purging program run for a couple of minutes. This will prevent captured air bubbles from remaining in the system which might have been the cause for a later safety switch off of the temperature control. - Note the volume change of the thermal fluid (especially with oils) in connection with the operating temperature. At the lowest temperature required, the fluid must be above the minimum mark in the sight glass, and it must not overflow at the highest temperature required. In case of over filling, drain off the excess fluid into a suitable container via the expansion vessel drain (9) or drain (8).
Draining the machine and an externally closed application General - Before draining the unit, the thermal fluid should be at ambient temperature (approx. 20 °C). If not, let the machine run with a set-point of approx. 20 °C for a few minutes until the thermal fluid is at a safe temperature. - Connect one end of a suitable drain hose to the drain of the unit (8), and place the other end into a suitable container (make sure the hose and container materials are compatible with the thermal fluid being used. Draining - Open the drain valve (4) if available. - The thermal fluid should flow through the pump case, and drain port into the container. - Disconnect the hose from the unit’s circulation flow (1). - Disconnect the hose from the unit´s circulation return (2). - Leave the temperature control device open to dry out for some time (without sealing caps and open drain valve (4). Changing thermal fluid / internal cleaning - After emptying the unit as described in the chapter Draining the machine and an externally closed application depending on the thermal fluid, it is possible that remnants of the oil remain in the machine. - Connect a short hose between the circulation return (2) and circulation flow (1) of the unit. - When having used silicon oils as thermal fluid, use a suitable solvent (e.g. Mucasol) to clean the internal components such as pump housing, reservoir, etc. Depending on the amount of contamination, it may be necessary to drain the solvent off, and repeat the procedure a number of times with clean solvent. - Afterwards, leave the temperature control device stand for some time (open all drain valves and have the connections opened). 67
