2Safety
2.1 Intended use
The GRANUDOS Flex dosing device and the buffer tank may only be used for the disinfection of swim-
ming pool water with calcium hypochlorite.
Also pay attention to the locally applicable regulations concerning accident prevention, occupational
safety and drinking water protection!
NOTICE!
The Granudos standard booster pump (BP) is not suitable for saline water (seawater/brine pools).
A special version is available for this case. Pay attention to this when placing your order!
2.2 Safety notices
Carefully read and pay attention to the operating instructions prior to installation and use of the de-
vice!
Work on the device and changes in the settings may only be carried out by properly instructed persons!
ATTENTION!

2.2.1 Handling of chemicals, risks to humans and the environment
DANGER DUE TO CORROSIVE SUBSTANCES!
Formation of substances hazardous to health when handling and mixing chemicals!
In emergencies, contact the respective poison control centre.
EMERGENCY NUMBER:
MUNICH EMERGENCY POISON CENTRE (OR ANY OTHER POISON CENTRE)
PHONE: [phone]
2.2.2 Protective measures and rules of conduct
DANGER DUE TO CORROSIVE SUBSTANCES!
Development of chlorine gas when mixing chemicals!
The GRANUDOS Flex dosing system doses both the calcium hypochlorite granulate and the
pH-reducer (acid) from the delivery container. These substances have a strong reaction
when combined and release toxic chlorine gas outside of water.
For this reason, the greatest possible care is required when working with these
chemicals!
Wearing personal protective equipment is essential: Face protection, protective
gloves, protective apron, foot protection.
The chlorine granulate and the acid must not be mixed with each other or with other
chemicals or substances!
Store chemicals in such a way that they are not accessible to unauthorised persons.
When storing chemicals, pay attention to the chemical manufacturers’ safety data
sheets!

3.2 Product description
The GRANUDOS dosing system is used for the disinfection of swimming pool water with calcium hypo-
chlorite.
3.2.1 Functional description of the overall system
The GRANUDOS Flex represents a dosing device for dosing calcium hypochlorite granulate. The chem-
ical is dissolved and fed into the pipe by means of a booster pump (BP) via an injector. The acid dosing
required for pH regulation of the swimming pool water is integrated and organised via the software
and a relay system in such a way that a joint dosing of chlorine and acid is excluded. The GRANUDOS
Flex dosing device is particularly well-suited for swimming pools with a water volume between 50 and
400 m³.
The functions of the GRANUDOS Flex-CPR Touch XL
Measuring of free chlorine with open measuring cell potentiostatic, pH value, redox potential and
temperature
Controlling the chlorine dosing using the measured value for free chlorine or for redox potential.
Dosing of chlorine granulate from the dosing hopper using the dosing screw and the knocker
Dosing of acid (pH-reducer) from the delivery container using a peristaltic pump
Dosing of flocculant from the delivery container using a peristaltic pump
Filling a buffer tank with chlorine solution for disinfecting additional small pools using dosing pumps
(option)
The functions of the GRANUDOS Flex-Touch
Dosing of chlorine granulate from the dosing hopper using the dosing screw and the knocker
Dosing of acid (pH-reducer) from the delivery container using a peristaltic pump
Filling a buffer tank with chlorine solution for disinfecting additional small pools using dosing pumps
(option)
The functions of the GRANUDOS Flex-S5
Dosing of chlorine granulate from the dosing hopper using the dosing screw and the knocker
Dosing of acid (pH-reducer) from the delivery container using a peristaltic pump
