Page 7: Safety Notes
UWT circulation heat exchangers Safety notes General safety notes A circulation heat exchanger is used to cool and circulate heat transfer liquids as specified. This leads to hazards due to the emission of heat transfer liquid and / or of cooling liquid and to general hazards due to the use of electrical energy. -
Page 8: Other Safety Notes
UWT circulation heat exchangers Other safety notes Connect the unit only to grounded mains power (PE). Use suitable hoses. Protect tubing with hose clips against slipping off. Prevent kinking of tubing! Check tubing from time to time for possible material defects! ... -

Page 11: Unit Description
UWT circulation heat exchangers Unit description Environmental conditions The operation of the thermostats is only allowed under the following conditions as specified in EN 61010-2-010:2003 and EN 61010-1:2001: Indoor use. Altitude up to 2000 m above sea level. ... -
Page 12: Temperature Display, Controller And Safety Devices
UWT circulation heat exchangers Temperature display, controller and safety devices The circulation heat exchanger can be switched on and off externally via contacts on the signal connect- or 15N. The units are equipped with a two-state controller on which the set-point temperature of the bath circuit can be set. -
Page 13: Unpacking
After unpacking, first check the unit and accessories for any transport damage. If contrary to expectations the unit is found to be damaged, the shipping company must be immediately in- formed so that verification can take place. Please also inform the LAUDA Service Constant Temperature Equipment (Contact 7.3). -
Page 14: Preparations
UWT circulation heat exchangers Preparations Siting and connection Site the unit on a level surface. The unit must not be put into operation if its temperature due to storage or transport has been reduced below the dew point. Wait approx. 1 hour. For operation, contacts 1 and 3 on the remote socket 15N must be joined. -
Page 15: Filling
UWT circulation heat exchangers Filling The circulation heat exchangers in the primary and laboratory circuits are designed for operation with water or a glycol/water mixture. Close the drain tap (located right at the bottom on the back panel). ... -
Page 16: Draining / Frost Protection
UWT circulation heat exchangers Draining / frost protection If the unit is to be taken out of operation for a longer period of time or if ambient temperatures below 0 °C are to be expected, the unit must be drained. This must be carried out in two steps: Draining the cooling liquid circuit: ... -
Page 17: Starting Up
UWT circulation heat exchangers Starting up Mains connection Compare the details on the rating label (back of the unit) with the mains voltage. Only connect units to sockets having a safety earth conductor (PE). No liability is accepted for incorrect mains connection. ... -
Page 18: Adjusting The Outflow Pressure With The Bypass Valve
UWT circulation heat exchangers Setting the switching threshold for overtemperature: Factory setting is 25 °C. Setting in the complete temperature range of the unit is possible. The setting takes place at the configuration level. Programming (setting) of the operating parameters is possible at the configuration level. -
Page 19: Maintenance
Withdraw the mains plug before all servicing and repair work! Have repairs in the control section carried out only by specialists! LAUDA circulation heat exchangers need practically no servicing. If the temperature stabilising liquid in the laboratory circuit becomes contaminated, it should be renewed. -
