The mounting material includes screws, wall plugs, washers and nuts.
● Mount the Oxiperm
wall using the enclosed mounting material.
● Select the mounting height such that the containers with chemicals can be
located underneath, and that the controller display is easy to read. The
water tank should also be located underneath the dosing pump for the
dilution water.
● The liquid level of the containers when full with chemicals should always
be below the dosing pumps.

CAUTION
NOTE
It must be possible to insert the suction lines (items 5 and 6) for hydrochloric acid
and sodium chlorite into the tanks without tension.
● Install the suction hose, return hose and the two empty alarm cables of the
suction line in the tank such that the bottom end of the suction line is
approx. 1 cm above the base of the tank.
● In the case of the Oxiperm
water supply line with a shut-off valve, and route the remaining part of the
line up to the inlet connection in PVC tube, and connect.
● In the case of the Oxiperm
dilution water line in a PVC tube as directly as possible from the main water
line up to the inlet connection. Provide a sampling shut-off valve on the
main water line.
WARNING
!
● Route chlorine dioxide solution line to the injector in PVC tube.
A shut-off valve should also be fitted in this line directly upstream of the
injector.

The system must be freely accessible on the left and
right for maintenance work (approx. 50-60 cm space).
The mounting material also contains a M6x20

If the sampling line and the solution line are connected
to the same water circuit, a check valve must be fitted
in the main line between the dilution water sampling
point and the injector. This valve prevents circulation of
the solution with dangerous building up of chlorine
dioxide.
