12. Decommissioning
This section includes the information of how to decommission
hydraulic and electric components. Beside this you find a
description of packaging and storing the system.
12.1 Hydraulic components
12.1.1 Dilution water hose
1. Close the dilution water isolating valve, remove and coil up
the hose.
2. Remove the cover from the system.
3. Unscrew the screw connection on the solenoid valve, and
detach the dilution water hose from the solenoid valve.
12.1.2 Suction lances
1. Unfasten the screw connection on the suction hose from the
HCl pump. Place the suction lance and suction hose in a
bucket of water. Rinse thoroughly with water.
Place on a cloth to dry.
2. Unfasten the screw connection on the suction hose from the
NaClO
2
pump. Place the suction lance and suction hose in the
other bucket of water. Rinse thoroughly with water. Place on a
cloth to dry.
3. Close the HCl container with the original cover and dispose in
a professional way.
4. Close the NaClO
2
container with the original cover and
dispose in a professional way.
12.1.3 Dosing line
1. Drain the dosing line at the multi-function valve.
2. Detach the dosing line from the multi-function valve. Drain the
ClO
2
solution into a bucket.
3. Detach the dosing line from the injection unit. Remove it from
the protective pipe and coil it up. Drain the ClO
2
solution into a
bucket.
4. Lay out the dosing line in the open air to allow ClO
2
residues
to escape.
5. If applicable, detach the dosing line of the external dosing
pump from the internal batch tank. Lay out the dosing line in
the open air to allow ClO
2
residues to escape.
12.1.4 Volume compensation bag
1. Wear gloves, face mask and protective apron.
2. Squeeze the volume compensation bag with the hands to let
gas residues escape via the activated carbon filter or
adsorption filter.
3. Unfasten the screw connection between the hose and the
volume compensation bag. Detach the hose to let gas
residues escape.
12.1.5 Activated carbon filter/adsorbent
1. Put on protective clothing: gloves, face mask, protective
apron.
2. Remove the activated carbon filter, see section
10.5.2 Replacing the activated carbon filter or remove the
adsorbent, see section 10.6.4 Replacing the adsorbent.
3. Dispose the carbon filter/adsorbent in a professional way.
12.1.6 Measuring cell
1. Detach the hose from the sample-water extraction device, and
detach it from the measuring cell.
2. Detach the sample-water discharge hose from the measuring
cell, and coil it up.
12.1.7 Measuring module or bypass mixing module
• Detach the two hoses connecting the measuring module or
bypass mixing module to the main line.
12.1.8 Disposal
• Pour the contents of the buckets down the drain. Rinse the
buckets thoroughly with water.
• Clean the installation room.
12.2 Electrical components
1. Detach the power supply cable from the main switch.
2. Detach the power supply cable from the control unit.
3. Detach the cable from the water meter.
4. Detach all cables from the measuring cell.
5. Detach the cable from the measuring or bypass mixing
module.
12.3 System frame
1. Get two people to hold the system frame.
2. OCD-162-5 and -10: Unfasten the three fixing screws in the
system frame, remove the system from the wall and place it
on a working surface.
OCD-162-30 and -60: Unfasten the four fixing screws on the
floor.
3. Leave the system and accessories for at least 24 hours before
packaging to allow them to dry.
Warning
Incorrect dismantling may result in serious personal
injury and damage to property. The system may only
be dismantled by authorised service staff.
Warning
Risk of burns due to the escape of chemicals from
dismantled seals, valves, connections, hoses, lines
or injection unit.
Flush the system twice in succession before starting
to dismantle it.
Do not bring dismantled suction lances into contact,
or place them in the same bucket. Always check the
label.
Check that the reaction tank and internal batch tank
are empty before dismantling them.
Drain the dosing line and put on protective clothing
before dismantling it.
Do not use cleaning agents.
Chemicals react with oils, fats and acids, see section
2. Safety instructions.
Warning
Risk of gas poisoning due to the escape of ClO
2
from
the dismantled gas hose, volume compensation bag
and activated carbon filter.
Wear protective clothing (gloves, face mask,
protective apron) when dismantling the gas hose and
the activated carbon filter.
Do not hold your face over the reaction tank, the
volume compensation bag or the activated carbon
filter.
Note
If the system is to be recommissioned at a later date,
remove the hoses and lines very carefully and do not
bend them. Tighten nuts by hand only.
Warning
Risk of electric shock from live lines.
Disconnect the system from the power supply before
starting to dismantle it.
Caution
Do not kink the cables and hoses.
