3. Safety information 1 1 General safety notes A through flow cooler serves for due cooling of heat transfer liquids which are tempered by means of a bath thermostat and transferred by pumping This leads to hazards through high temperatures fire and the general hazards through the use of electrical energy The user is largely protected through the application of the appropriate standard specifications Additional hazards may arise from the type of material being thermostated e g when going above or below certain temperature levels or through breaking of the container and reaction with the heat transfer liquid It is not possible to cover all possibilities they remain largely within the responsibility and the judgement of the user The equipment must only be used as intended and as described in these Operating ee Instructions This includes operation by suitably instructed qualified personnel The units are not designed for use under medical conditions according to EN 60601 1 or IEC 601 1 1 2 Other safety notes Connect the equipment only to an earthed supply socket Use suitable hoses Protect tubing with hose clips against slipping off Prevent kinking of tubing Check tubing from time to time for possible material fatigue Heat transfer tubing and other hot parts must not come into contact with the supply cable During operation of the through flow cooler hot tempering liquid may penetrate through the hose in case o
