Vacuum Regulator for Chlorine Gas
C 2700-V
Operating Instructions
BA-21210-02-V05
Installing the connection with flange connection
Precondition for action:
The inside of the supply line is clean and dry.
The transport protection has been removed.
The sealing surfaces are free of contamination and damage.
The seals are clean, undamaged and dry.
The screws, nuts and washers are clean and undamaged.
Fig. 6-2: Installing the flange connection
Perform the following working steps:
1.
Lubricate the sliding surfaces and threads of the screw, nuts and
discs using, for example, fitting or PTFE grease.
2.
Place the flat gasket (2) onto the projecting tongue of the connec-
tion flange (1). Install the seal whilst dry.
3.
Place the groove flange (3) of the vacuum regulator in position.
Make sure that the flat gasket does not slip.
4.
Attach the screws (4), discs (5, 6) and nuts (7) by hand.
5.
Tighten the screws evenly in three stages crosswise: 20 Nm, 35
Nm, 50 Nm. After this, retighten all the screws to the full target
tightening torque (50 Nm).
6.
Setting the seal (adapting to the flange seal surface) can make it
necessary to retighten the screws). Thus the screws should be
retightened to a torque of 50 Nm after a few hours.
Installed chlorine input with flange connection.
Installing the connection with threaded connection
Precondition for action:
The inside of the supply line is clean and dry.
The transport protection has been removed.
The threads are bare metal.
Perform the following working steps:
1.
Clean the threads with a degreasing cleaning agent, e.g., alcohol.
2.
Allow the threads to dry completely.
3.
Apply the thread sealant compound around the male thread at the
start of thread. Keep the first thread pitch clear. Press the thread
sealant compound into the thread groove to ensure the thread
flanks are well moistened.
Fig. 6-3: Seal the threads.
4.
Guide the threaded pin into the internal thread and, in doing so,
apply a little adhesive to the internal thread. Screw the components
together by hand.
5.
Tighten the connection using tools. When doing this, the tool must
only be used on the metal inlet valve and not on the PVC component
of the vacuum regulator. The thread size 1" NPT demands approx.
150 Nm
6.
Remove any excess adhesive with a cloth.
Any screws, nuts and washers that are removed during
installation must be replaced with new ones if damaged.
Used screws, nuts and washers may only be installed if they
are in at least new condition.

DANGER
Danger to life from chlorine poisoning!
Use chlorine-resistant material for sealing pipe connections and fit-
tings in pressurised pipes. Inadequate sealants will react with chlo-
rine and cause leaks.
Use only sealants that resist contact with chlorine (e.g., anaero-
bic sealing compounds).
NOTICE
Leak due to incorrect installation
To correctly align the connection, it may be necessary to turn the
thread in an anticlockwise direction. When releasing the connec-
tion, bubbles form in the adhesive which can result in leaks.
Only turn the thread in a clockwise direction.
If, after tightening, the connection is not correctly aligned,
repeat steps 1 – 5.
