9.4 Safety valve
For maintenance purposes the safety valve has to be cleaned and inspected optically.
The valve seat and the diaphragm have to be exchanged. For dismounting the valve seat you can use pointed
pliers for example. In doing so, makesure not to damage the PVC housing! The new valveseat and diaphragm
have to be lubricated with silicone grease. The PVC threads also have to be lubricated with silicone grease in
order to be able to unscrew them easily later on.
The safety valve leakage test is carried out by producing a vacuum using the ejector while the chlorine cylinder
is closed. For this purpose a transparent tubing is connected to the blowoff connector (centric connector) with
the other end immersed in water. The water must not rise in the tubing.

9.5 Activated-carbon cartridge
The filling of the activated-carbon cartridge has to be exchanged either if it is loaded with chlorine or if it gets
lumpy due to humidity.
CAUTION!
There is a strong chlorine smelling if activated carbon is loaded with chlorine gas. Therefore you should abso-
lutely never exchange the filling in closed rooms or in the proximity of aspirating mouths of ventilating systems.
For chlorine neutralization, sodium thiosulfate solution is perfectly suitable.
