Installation and Commissioning
The injection nozzles for disinfectant and pH adjusting solution
are fitted in the line between the filter system and pool inlet. If a
flow-through chlorine electrolysis system is used for disinfection,
the acid injection nozzle must be fitted in front of the electrolysis
cell.
5.4.1 Sample water supply
For shipping purposes all the water connections for the water
sample station have been unscrewed and must be refitted to the
water sampling station. Refer to the station scale drawing for the
correct positioning.
The correct hose and connections for the pipe system are includ-
ed in the delivery supply. The screw-in connections are sealed
with PTFE tape. The hose should be installed without kinks.
Hose connection
Cut off the hose at right angles with a sharp knife.
Push the union nut onto the hose.
Push the hose onto the cone of the connection.
Tighten the union nut carefully. (Plastic!)
NOTICE!
For subsequent maintenance work it is useful if shut-
off valves can be fitted to all site connection points.
NOTICE!
If there are likely to be coarse particles in the sample
water, a sample water filter must be installed (see chap-
ter 8).
5.4.2 Dosing system assembly
An injection nozzle, pressure line and suction line are supplied
with each peristaltic pump. The injection nozzle is immersed with
the transparent hose in the pipeline. It is screwed in the arrow
direction and sealed with PTFE tape.
Fig. 5.4..1: Injection nozzle (the arrow points in the direction of the pipeline)
Suitable dosing hose for routing between the peristaltic pump
and the injection nozzle is included in the supply. The suction
hose and pressure line should be routed without kinks. Note the
peristaltic pump entry and exit points.

Hose connection
Cut off the hose at right angles with a sharp knife.
Push the union nut onto the hose.
Push the clamping ring onto the hose (note the alignment).
Push the hose onto the tap of the connection.
Push on the clamping ring.
Tighten the union nut carefully. (Plastic!)
NOTICE!
The peristaltic pumps are only controlled after the
sensors have been calibrated to ensure imprecise
measurements do not result in faulty dosing. The
suction lines should only be immersed in the chemi-
cal containers when the calibration has been suc-
cessfully completed.
NOTICE!
Chlorine bleach (natrium hypochloride solution)
must never be mixed with acid. Poisonous chlorine
gas would be released immediately. For this reason
warning notices accompany systems for using chlo-
rine bleach. These must be attached close to the
system.
5.4.3 Adjusting the sample water flow
Fig. 5.4.3 Adjustment valve
Set all the valves on the sample water line to the 100% open po-
sition. When operating the filter pump the water flow is adjusted
via a screwdriver on the needle valve. (arrow)
Close the valve fully (clockwise)
The controller shows "insufficient sample water".
Slowly open the valve (anti-clockwise) until the "insufficient
sample water" display goes out.
Check by applying the inlet ball valve. The "insufficient
sample water" display appears when the ball valve is closed
and goes out again when it opens.
For water sampling stations with a chlorine measuring cell the
correct sample water flow is set when the glass balls in the
measuring cell for cleaning the electrodes safely reach the high-
est point of the measuring cell.
