Check for proper seating of the belts.
6 6.2.3 Operation Filling the cooling media tank Do not connect and operate before filling with coolant. Mind the maximum fill level! We recommend a mixture of ethylene glycol / water at least 30/60, which does not freeze until -16 °C. NOTE If you have a large closed cycle cooling system (e.g. long hoses, many condensers connected to the system in series) fill the refrigerant tank to maximum level. NOTICE Risk of instrument damage if wrong cooling medium is used. • 6.
6 Operation Working steps • T he cooling temperature can be adjusted during the operation process by pressing the UP and DOWN buttons on the Chiller. • If the Chiller can’t keep the required temperature perform a slower distillation, by means of decreasing the vacuum to a slightly higher level so that less vapor is coming to the cooling coil. Steps for end of process • Press the STOP button on the Chiller. ➡➡ The cooling stops immediately. ➡➡ After a few seconds ventilation also stops.
