3.4 Authorized service personnel

The system may only be maintained and serviced by authorized
service personnel trained by Grundfos.

3.5 Correct usage

Oxiperm Pro OCD-162 is a system for generating a chlorine
dioxide solution out of hydrochloric acid (9 %) and sodium chlorite
(7.5 %), and the continuous dosing of this solution for water
disinfection.

3.6 Inappropriate usage

Applications other than those listed in section
are not in accordance with the intended use and are not
permitted. The manufacturer, Grundfos, accepts no liability for
any damage resulting from incorrect use.
A chlorine dioxide solution with an uncritical concentration of
2000 ppm (2 g/l) is generated in the reactor. Hence the
Oxiperm Pro OCD-162 operates far out of the range of critical
concentrations.
Danger of explosion in case of overdosage: At a concentration of
more than 30,000 ppm (30 g/l) the chlorine dioxide solution can
explode.
Gaseous chlorine dioxide is a chemically unstable compound.
At concentrations over 300 ppm (300 g/m
chlorine and oxygen explosively without external impact.
Warning
Unauthorized structural modifications to the
system may result in serious damage to
equipment and personal injury.
It is prohibited to dismantle, modify, change the
structure of, bridge, remove, bypass or disable
components, including safety equipment.

3.7 Safety and monitoring equipment

The system features control alarms that monitor ClO
An additional gas warning device is available as an accessory.

3.8 Chemicals

3.8.1 Chlorine dioxide concentration
In the reaction tank of the Oxiperm Pro OCD-162, diluted sodium
chlorite and diluted hydrochloric acid are mixed to create a
chlorine dioxide solution with a concentration of approximately
20 grams per liter of water. After further dilution and according to
the disinfection demand, the Oxiperm Pro OCD-162 doses the
diluted chlorine dioxide solution into the main line to be
disinfected. The ClO concentration in drinking water must not
2
exceed a maximum of 0.4 milligram per liter of water according to
some drinking water ordinances; check federal, state, and local
ordinances. Under adverse conditions, the 55 g system could
potentially liberate 1.5 g ClO gas.
2
Warning
Risk of explosion when using chemicals in too
high concentrations.
Only use sodium chlorite in a diluted
concentration of 7.5 % by weight in accordance
with EN 938.
Only use hydrochloric acid in a diluted
concentration of 9.0 % by weight in accordance
with EN 939.
Observe the safety data sheets from the
chemicals supplier.

Warning
Risk of explosion when mixing up chemical
containers or suction lances.
Possible consequences are personal injury and
serious damage to equipment.
Do not mix up chemical containers or suction
lances.
Observe the labels on chemical containers,
suction lances and pumps: red = HCl,
blue = NaClO .
2
Warning
Risk of burns when skin and clothing come into
contact with sodium chlorite and hydrochloric
acid.
Immediately wash affected skin and clothing with
water.
Warning
Risk of irritation to eyes, respiratory system and
skin, if chlorine dioxide is inhaled.
When changing the chemical containers, wear
personal protective equipment per OSHA
guidelines and as directed by local/state/national
regulations.
Warning
The temperature of the chlorine dioxide solution
stored in an external batch tank may not exceed
104 °F (40 °C).
Risk of outgassing at more than 104 °F (40 °C).
Note
Note
Installing a gas warning device is recommended.
Chemicals must be stored in the appropriately marked original
plastic containers.
Do not store chemicals near grease, flammable substances,
oils, oxidizing 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.
