Page 9: Unit Description
One of five pump output steps can be selected using the operating menu. On small low-temperature thermostats (e.g. RE 104 or RE 106) and with operation as bath thermostat it is advisable to use output step 2. The advantage is a low heat generation while having a uniform circulation. -
Page 10: Temperature Indication, Control, And Safety Circuit
Unit description Temperature indication, control, and safety circuit The equipment is provided with a 7 segment LCD-Display (3 places) with additional symbols for ½ indicating bath temperature and settings as well as operating states. The setpoint can be input and additional adjustments can be made using either two or three keys. -
Page 11: Unpacking
Unpacking Unpacking After the unit and accessories have been unpacked they have to be examined for possible transport damage. If there is any damage visible on the unit, the forwarding agent or the post office has to be notified so that the shipment can be examined. Standard accessories: Bath cover on all low-temperature thermostats except for RE 120... -
Page 12: Preparations
Preparations Preparations Assembly and setting up − Place the unit on a flat surface − After transport and before starting up, store it standing in upright position for two hours if possible − Do not cover the ventilation openings at the back of the unit and its lower part. -
Page 13: Filling And Emptying
Preparations − The unit can be operated safely up to an ambient temperature of 40°C − Depending on the loading of the refrigeration system, a temporary shut-off can occur, especially in case of an ambient temperature of over 35°C. Additionally a higher ambient temperature results in less refrigerating capacity. −... - Page 14 Preparations Emptying − Switch off the thermostat, pull out the mains plug! − Drain the bath liquid through the drain cock ! using tubing. − The units are designed for operation with non-flammable and flammable liquids to EN 61010-2-010! Flammable liquids can be operated up to no more than 25°C below the firepoint ( Section 5.3.).

Page 22: User Calibration
Starting up 6.4.3 User calibration − Remove the external consumers and switch the setting knob of the pump to right side. ( Section 5.4). − A reference thermometer with necessary accuracy is required. Otherwise the factory calibration should not be altered. The reference thermometer has to be inserted far enough and long enough into the bath. -
Page 23: Warning And Safety Functions
Starting up Example a) Insert a suitable thermometer into the bath (long enough and far enough). b) Remove the external consumers and turn the setting knob of the pump outflows to the right side. c) Set the setpoint to a temperature where you use to work (e.g. set the setpoint to 45°C Section 6.3.) d) Wait until the actual bath temperature has reached the setpoint temperature of 45°C and until the indication on the reference thermometer does not change any more. - Page 24 Starting up " " " " − When the bath temperature arises above the overtemperature switch-off point. 1. Double signal tone sounds 2. The display shows the indication for overtemperature ttt the fault triangle is flashing ! heating is switched off on both poles, ! pump and refrigeration system are switched off by the electronics.

Page 27: Safety Notes
Safety notes Safety notes General safety notes A laboratory thermostat is intended for heating and pumping liquids according to the needs of the user. This leads to hazards by high temperatures, fire, and the general hazards by the use of electrical energy. The user is largely protected through the application of the appropriate standard specifications.. - Page 28 Safety notes produced. Ensure appropriate ventilation! • When changing the bath liquid from water to oil, for temperatures above 100 °C, carefully remove all traces of water, also from tubing and from the external consumer, otherwise ! danger of burns through delayed boiling! •...

Page 29: Maintenance
− Before any maintenance and repair work pull out the mains plug! − Repairs on the control unit must only be carried out by properly qualified personnel! LAUDA thermostats are largely maintenance-free. If the thermostating liquid becomes dirty it has to be replaced ( Section 5.2.). -
Page 30: Maintenance Of The Refrigeration Unit
If the equipment does have to be returned to the factory, it may only be necessary to dismantle the thermostat unit and return it. − If the equipment has to be returned to the factory, please ensure that it is carefully and properly packed. LAUDA accepts no responsibility for damage due to unsatisfactory packing. Ordering spares When ordering spares please quote instrument type and serial number from the rating label. -
