Chlorinator C 2700
BW 2 03 01 / 3
Operating and Maintenance Instructions
below the chlorinator (10) into a water tank. Open shutoff
valve (16) and motive water line. The chlorinator is then
under vacuum. When the gas line is closed, a column of
water is primed according to the displacement volume of
the diaphragms and can be seen in the transparent
tubing.
If the device is absolutely tight, the column of water will
have a constant level. If there is a leak, the water will
continue to rise. Interrupt the test,
before
water enters
the chlorinator. See troubleshooting table.
Safety Valve
The safety valve installed in the center chamber of the
chlorinator is closed if the chlorine gas inlet valve is
operable. If it leaks due to contamination or wear, an
excessive pressure is produced in the lower chamber.
The safety valve opens at an excessive pressure of
approx. 0.5 bar and, via the vent line, carries the chlorine
gas outside or to the installed warning device. Check this
line using a small amount of ammonia solution (liquid
ammonia) when starting up the installation.
Replacing the Measuring Glass
For replacement, remove the measuring glass (k) together
with the receiving blocks (b). The spacer bolts (c) can be
dismounted after screwing off the cap nuts (d). After
loosening the screws (h), the receiving blocks (b) can be
removed. For assembly, proceed as follows:
Prepare both receiving blocks (b) by positioning the
flange bushing (e) in the recess of the receiving block and
by covering it with the rubber ring (f). Then the flange (g)
(still without measuring glass) is fastened manually with
screws (h). The measuring glass (k) is prepared by
inserting the float (i) with the point showing downward
and the fitting edges (l) into the measuring glas ends.
Then the preassembled blocks are slid onto the measuring
glass ends. Insert the spacer bolts (c) and fasten with
nuts (d) by turns so that the receiving blocks are parallel
to each other. The prepared measuring set is fixed to the
base plate. Now tighten the spacer bolts (c) gently by
turns. Fasten the flanges (g) with the screws (h) and
connect the lines.
Chlorinators
The chlorinators are installed perpendicularly, because
the measuring glass must be vertical for accurate
indication. The motive water and solution lines have to be
connected to the injection nozzles, in accordance with
the ejector nominal widths and free of tension. In the case
of long solution lines, the pressure loss must be considered
as back pressure of the ejector.
Sprinkler System
All rooms storing chlorine should have a sprinkler system
(24), which cleans the air if chlorine gas escapes. The
system can be switched on outside the room by means
of a hand valve (23) with an extended spindle or by a
solenoid valve (22) controlled by the gas warning device
(25).
Tests Before Startup And For Maintenance
Purposes
Motive Water And Solution Line
If the existing motive water pressure is lower than 10 bar,
the shutoff valve (16) can be closed for the pressure test.
Open the motive water valve slowly and check for leaks.
Fasten the screwed PVC joints manually. Leaking
cemented connections must be renewed with balanced
lines. At motive water pressures of more than 10 bar, the
shutoff valve (16) must always be open in order to protect
the ejector. The system pressure prevailing at the injection
nozzle becomes effective.
Ejector Non-Return Valve
For pressure test, close shutoff valve (injection nozzle)
and open motive water line slowly. Disconnect suction
tubing at the joint of the non-return valve (13). The valve
must not leak. If it is leaking, dismount the valve and
eliminate the error.
