pressure is built up, the blockage is located between lower seal
holder and outlet valve. The following parts can be blocked:
lower seal holder, cooling unit, capillary, outlet valve. These
parts must be exchanged or cleaned by a service technician.
A leak test must be carried out to ensure the tightness of the
SpeedExtractor.
If pressure builds up, the top cover plate or the parts up to the
solvent valve are blocked. Release the pressure manually. The
top cover plate can be exchanged or cleaned by the operator. If
parts before the top cover plate are blocked the service techni-
cian has to exchange or clean these parts.
