1. Transport the equipment with care Equipment and its internal parts can be damaged by dropping by shock Equipment must only be operated by technically qualified personnel Never operate the equipment without heat carrier liquid Do not start up the equipment if itis damaged or leaking Cable not only supply cable is damaged Switch off the equipment and pull out the mains plug for servicing or repair moving the equipment Do not carry out any technical changes on the device Have the equipment serviced or repaired by properly qualified personnel only The Operating Instructions include additional safety notes which are identified by a triangle with an exclamation mark Carefully read the instructions and follow them accurately Disregarding the instructions may have serious consequences such as damage to the equipment damage to property or injury to personnel We reserve the right to make technical alterations YACE0082 04 10 06 Safety notes 3 LAUDA High temperature cooling HTC with LiBus Control 1 1 Safety information e A high temperature cooler is used to cool temperature stabilizing liquids as prescribed This leads to hazards due to the hot temperature stabilizing liquids the emission of water and to general hazards due to the use of electrical energy e The user is largely protected by the application of the relevant standards It is not possible to include all possibilities Th2. Non cooling mode and the maximum cooling power is reduced in the Cooling mode An application specific optimum can be achieved by the step by step adjustment Optimization is particularly advantageous with large baths from P 12 upwards Guide value If with the P8 the external selec tor is set to 50 vertical position then the time required for cooling extends by approx 50 e g from 200 C to 100 C from previ ously 8 minutes to 12 minutes In this way better circulation is achieved with a tempera ture accuracy up to 0 02 C Then optimize the control parameters accord ing to the Proline operating manual Set the Proline bypass valve 5 to Exter nal In this operating mode the pump flow must always be shared between the external load and the HTC To do this connect the external load to the second pump connection on the Proline thermostat A serial arrangement is unfavorable because the valve K1 of the HTC see 3 is closed in some operating states so that only a very small part of the flow is left to pass through the HTC bypass D1 It may be necessary to also adjust the flow through the reducing valves so that both the HTC and the external load receive sufficient flow Then optimize the control parameters accord ing to the Proline operating manual Starting up 11 LAUDA High temperature cooling HTC with LiBus Control 7 Draining frost protection If the HTC high temperature coole
