2.6.6 Connection to injection valve with steel capillaries
For the pressure range 25 … 50 mPa (250 … 500 bar) we recommend to
use 6.2620.020 Steel capillaries, a 6.2620.150 Pulsation dampener (see
section 2.6.2) and a 6.2821.000 Filter unit Manufit (see section 2.6.4) to
connect the 709 IC Pump and the injection valve of the 733 IC Separa-
tion Center. Proceed as follows:
For the connection of capillaries to the injection valve, use only the
special steel connectors contained in a plastic bag affixed to the
valve. If other steel connectors are used (e.g. 6.2620.000 and
6.2620.010), the valve connection may be damaged!
1 Connection to 709 IC Pump
• Attach inlet capillary 56 56 of the Manufit filter unit 69 69 to connec-
tion 23 23 of the 709 IC Pump (see 709 Instructions for Use).
• Attach outlet capillary 63 63 of the filter unit Manufit 69 69 using
coupling 70 70 to a steel capillary 71 71 cut to the required length
(see Fig. 14).
