JULABO FPW91-SL Ultra-Low Refrigerated Circulators - Manual (Page 28)

Preparations
28
Unsuitable bath fluids are fluids which, e.g.,
• are highly viscous
(much higher than recommended at the respective working temperature)
• have a low viscosity and have creep characteristics
• have corrosive characteristics or
• tend to crack.
• No liability for use of other bath fluids!
5.3. Temperature application to external systems
Caution: Securely attach all tubing to prevent slipping.
If the circulator is operated without external system, close the pump connector (22)
with the cap nut.

The circulator is used for temperature application to external,
closed systems (loop circuit) with simultaneous temperature
application in the circulator bath.
Model combination without HSP booster pump
Pump connection:
• Unscrew the M16x1 collar nuts on the pump connectors with a
19 mm (3/4“) wrench and remove the sealing disks. Using the
collar nuts, screw on the tubing connection fittings (for tubing
8 mm or 12 mm in diameter) delivered with the unit and tighten
firmly. (Pressure pump: 22, suction pump: 21)
• Push on the tubing, and secure with tube clamps.
• Attach the tubing to the connectors of the external closed
system, e.g., an instrument with a pressure-resistant
temperature jacket or a temperature coil, and fasten with tube
clamps to prevent slipping.
