1.4 Obligations
of the operator
The owner
of the building or the operator of the
Oxiperm Pro
disinfection system is responsible for the following:
•
Consider this manual to be part of the product and ensure
that it is kept clearly accessible in the immediate vicinity of
the system for the entire service life of the system.
•
Meet the installation requirements specified by the
manufacturer (required water connections and fittings,
environmental conditions, electrical connection, protective
tube for dosing line (if necessary), audible or optical warning
device for alarm messages (if necessary)). See section
.
•
Ensure that water lines and fixings are regularly checked,
serviced and maintained.
•
Obtain official approval for storing chemicals, if necessary.
•
Instruct
users in the operation of the system.
•
Ensure that the labels supplied by the manufacturer with the
system are clearly displayed in the installation location. For
illustration, see section
•
Provide the user code for the operating software only to users
who have received appropriate technical training.
•
Ensure that the regulations for the prevention of accidents are
observed in the installation location (German GUV-V D05
regulation for the prevention of accidents, "Chlorination of
Water" dated January 1997).
•
Provide all users and service personnel with protective
clothing in accordance with GUV-V D05 (face mask, gloves,
protective apron).
•
If the system has been ordered without a dosing pump, the
operator must provide an external dosing pump prior to
installation. This may only be connected to the
Oxiperm Pro
disinfection system by authorised and qualified personnel
from Grundfos Alldos.
1.5 Maintenance and service personnel
The system may only be maintained and serviced by authorised
service personnel from Grundfos Alldos.
1.6 Correct usage
The
Oxiperm Pro
disinfection system is used to mix a diluted
chlorine dioxide solution from 7.5 % sodium chlorite and 9 %
hydrochloric acid. In accordance with the conditions described in
this manual, it is used to dose the chlorine dioxide solution
produced continuously or non-continuously into the (drinking)
water line of a building or to introduce it into a swimming pool,
process water, wastewater or other industrial system for water
disinfection.
1.7 Inappropriate usage
Applications other than those listed in section
are not in accordance with the intended use and are not
permitted. The manufacturer, Grundfos Alldos, accepts no liability
for any damage resulting from incorrect use.
The system comprises state-of-the-art components and has
undergone safety-related testing.
1.8 Safety and monitoring equipment
The
Oxiperm Pro
disinfection system is fitted with the following
safety and monitoring equipment:
•
cover on the system frame
•
two collecting trays for the two chemical containers
•
safety/multi-function valve at the dosing pump
•
solenoid valve at the dilution water inlet
•
volumetric accumulator and activated carbon filter for ClO
2
gas that escapes from the reactor
•
alarm functions in the control system.
1.9 Chemicals
1.9.1 Chlorine dioxide concentration
In the reactor of the
Oxiperm Pro
disinfection system, diluted
sodium chlorite and diluted hydrochloric acid are mixed to create
a chlorine dioxide concentration of approximately 2 g per litre of
water. The system doses the diluted chlorine dioxide solution
according to the disinfection requirement into the main line to be
disinfected. According to the German drinking water ordinance
(TrinkwV 2001), the chlorine dioxide concentration in drinking
water must not exceed a maximum of 0.4 mg per litre of water.
The following safety instructions must be observed:
1.9.2 Storing chemicals
•
Chemicals must be stored in the appropriately marked
original plastic containers (20 to 33 litres).
•
Do not store chemicals near grease, flammable substances,
oils, oxidising substances, acids or salts.
•
Empty and full containers must be kept closed, especially in
areas where national regulations for the prevention of
accidents apply to storage (German GUV-V D05).
Warning
Unauthorised structural modifications to the
system may result in serious damage to
equipment and personal injury.
It is forbidden to dismantle, modify, change the
structure of, bridge, remove, bypass or disable
components, including safety equipment.
Warning
Risk of explosion when using chemicals in too
high a concentration.
Only use sodium chlorite in a diluted
concentration of 7.5 % by weight in accordance
with DIN EN 938.
Only use hydrochloric acid in a diluted
concentration of 9.0 % by weight in accordance
with DIN EN 939.
The safety data sheets from the supplier must be
observed.
Warning
Risk of explosion and serious damage to
equipment and personal injury as a result of
operating faults
due to confusing the chemical
containers or suction lances.
Do not confuse the containers.
Observe the red and blue markings on chemical
pumps, suction lances and chemical containers:
Red = HCl, blue = NaClO
2
.
Warning
Risk of burns when skin and clothing come into
contact with sodium chlorite and hydrochloric
acid.
Affected skin and clothing must be washed
immediately in water.
Warning
Risk of irritation to eyes, respiratory system and
skin if chlorine dioxide is inhaled.
When changing the chemical containers, wear
protective clothing in accordance with
regulations for the prevention of accidents
(German GUV-V D05, "Chlorination of Water"
dated January 1997).
