Hose connection: Fromthe pressure port to the external system and then back to the return port.
Filling 9. Filling with Bath Liquid The selection of the proper bath liquid (heat transfer liquid) influences the capacity of a temperature control unit decisively. The technical data with special emphasis on the temperature accuracy was established in accordance with DIN 58 966 (water at 70°C). The temperature accuracy will decrease the higher viscosity of the heat transfer liquid and the lower its heating capacity IS.
Methanol or Ethanol Those liquids are usually only used at lower temperatures. Their flash point is at about 10°C. Therefore, they cannot be used in accordance with the standards EN 61010 or DIN 12879. other temperatures Thermo Haake offers a range of heat transfer liquids for these temperature control applications. Synth ... : Synthetic thermal liquid with a medium life span (some months) and little smell annoyance. SIL ... : Silicone oil with a very long life span (> 1 year) and negligible smell.

When working with water or water with antifreeze: or with oil below ambient temperature: the filling level should be 2 cm below the deck plate. When working with oil above 80°C: Keep level somewhat lower. Oil expands when being heated. Rule of thumb: 10% volume increase per 100°Cheat increase.
10. Draining The temperature control unit is drained at the nozzle. Place a suitable vessel underneath nozzle. 0 Bear in mind that the liquid will run out in a slight arc. Turn plug slowly until it becomes disengaged from the thread. A pin will prevent the liquid from running out right away. Pull out plug (pin) in one quick motion. The liquid will start to run out. Possible residues can be drained by tilting the circulator slightly. Option: H I I Usethe liquid drain (order no. 333-0499).
Connecting Up 11. Connecting Up 11 .I Connecting to the mains Only attach this unit to mains sockets with a grounded earth. Compare the local mainsvoltage with the specifications written on the name plate. Voltage deviations of +/- 10% are permissible. The socket must be rated as suitable for the total power consumption of the unit. Make sure that the temperature controller F8 or N8 are safely connected to the refrigerated units with their two cables 30 and 32. 11.
Connecting Up 11.4 Fuses on the unit All units are equipped with automatic thermally-triggered fuses. If the fuse has triggered.. . the fuse does not have to be exchanged - resetting suf- fices; a white marking is visible; a certain cooling down time should be allowed (approx. 5 min) before the (dip) switch can be pressed again. ! Do not use tools; do not use force. Both destroy the fuse. ! If the fuse should be triggered again after resetting, the unit probably has a defect.

Cooling 19. Cooling The refrigerated bath is used mainly for enabling lower than ambient or tap water temperatures in circulators or for cooling a heated bath down to a low temperature level very quickly. The working temperature range is shown in the technical specifications. 0Safety measures have been taken in order to avoid an excessively high temperature in the cooling circuit which would then result in the excess temperature protection being triggered and the compressor being switched off.
Maintenance 20. Maintenance The stainless steel surfaces of the bath vessel and of the housing may after some time show spots and become tarnished. Normal stainless steel cleaners as they are used in the kitchen can be used. The bath vessel and built-in components should occasionally (at least every time the bath liquid is changed) be cleaned using a household cleaner. Vinegarbased cleaners have proved to be suitable used according to the manufacturers recommendations.
Disassembly 21. Disassembly of Temperature Control Module and Bath Vessel 1 0 0 Oo* . Switch off the unit and pull out the mains plug. Loosen the 2 crosshead screws right beside the pump connections. Slide the metal jacket to the front (slightly bending may be necessary) and remove it. Unscrew the 4 screws. A hexagon socket (10 mm) should be used if the screws are too tightly tightened. In case of difficulty loosen the sealing from the unit with a screw driver.

CONFII-OIANNINIOFF. 23.45 O C -<- After this, the value on the external device and the set temperature on the display of the circulator are adjusted. p F q Confirm with ENTER to save the offset value. On the display the voltage or current range of the selected mode is shown (e.g. 0...1 OV, O/lOO°C). For each channei an offset value can be saved. 23.3.
Appendix 23.3.6 Adjusting the output values Similar to the input of set values, when monitoring an actual value by means of an external device via the I10 plug, there can be a difference between the actual temperature shown on the display of the circulator and the actual value of the external device. This difference depends on tolerances in the I10 board and the external device. By setting an offset value, the value (i.e.
Appendix 23.4 Simultaneous operation of input and output Via the 110 plug you can either give set values (voltage or current input), monitor actual values (voltage or current output) or simultaneously give set values and monitor actual values. In this case, input and output channels can be combined at will (e.g. channel 0 for input and channel 7 for output).
