Safety information
Safety chapter
WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious inju‐
ries.
Please ensure when handling hazardous sub‐
stances that you have read the latest safety data
sheets provided by the manufacture of the haz‐
ardous substance. The actions required are
described in the safety data sheet. Check the
safety data sheet regularly and replace, if neces‐
sary, as the hazard potential of a substance can be
re-evaluated at any time based on new findings.
The system operator is responsible for ensuring
that these safety data sheets are available and that
they are kept up to date, as well as for producing
an associated hazard assessment for the worksta‐
tions affected.
WARNING!
Danger of electric shock
Mains voltage may be present inside the pump
housing and the switch cabinet.
– Immediately disconnect the system from the
mains power supply if the pump housing or
switch cabinet has been damaged. Only return
the pump to service after it has been repaired
by authorised personnel.
Potential danger from the system
CAUTION!
Please also observe the operating instructions for
the metering pump and any other units which may
be fitted.
CAUTION!
Do not climb onto the system or parts thereof - the
metering station cannot support the load, could
leak or topple over.
NOTICE!
Warning of illegal operation
Observe the regulations that apply where the
device is installed.
The following dangers could arise if incorrectly operated or mis‐
used:
Water pollution and damage to health
n Water pollution and damage to health due to escaping liquids.
n Damage to health from the inhalation of ammonia vapours.
n Dangerous reactions due to contact with other chemicals.

Page 10
Safety chapter
Take special precautions with storage and metering. The specific
potential danger and resulting hazards should be taken from the
current material safety data sheet for the substance used.
Danger of explosion
n Risk of explosion due to trapped ammonia-air mixtures.
A potentially explosive ammonia-air mixture (lower explosion limit
15.4 vol.%, upper explosion limit 33.6 vol.%) can form in the inte‐
rior of the metering vessel and also in the interior of the supply
drum via the liquid phase depending on the temperature and con‐
centration of the commercial ammonia water product.
The built-in level switch in the metering vessel is therefore
designed to be intrinsically safe “i” with an explosion-proof design.
Pay attention to any static charge when connecting or replacing a
supply drum!

Protective equipment
Warning labels
The system is provided with the following protection equipment,
which prevents large quantities of ammonia from escaping, or the
resulting ignition of an ammonia water-air mixture:
n The level switch in the metering vessel prevents overflowing.
n The system is designed so that the transfer from the storage
tank to the metering vessel is via a vapour recovery line.
n The aeration and venting of the system is through an active
carbon filter, which absorbs the escaping ammonia gas.
n The lid of the dosing tank protects the user from ammonia gas.
It needs to be secured by a seal when operating with ammonia.
n The level switches in the metering vessel and in the dosing
tank are designed to be explosion-proof and intrinsically safe “i”
with an appropriate explosion-proof intrinsically safe “i” switch
amplifier.
Further recommendations, the implementation of which is however
outside our area of responsibility:
n Place the dosing tank in a collecting pan.
Affix workplace labels in line with the current regulations.
They might look like this in accordance with the German regula‐
tions governing printing of the operating instructions:

Functional description
7 Functional description
The DULCODOS® Ammonia system is used for the gas-tight
transfer and dilution to usual metering concentrations and then
automatic metering into the feed water.
The dosing tank (12) needs to be filled with de-ionised water to
batch a diluted usable ammonia water solution. The transfer pump
(4) semi-automatically fills concentrated ammonia water solution
(max. 25%) from the supply drum (1) into a metering vessel (9). An
appropriate amount of this concentrated solution from this metering
vessel needs to be left in the dosing tank to obtain a final concen‐
tration of between 0.1% ... 2.5%.
The manual stirrer (10) mixes the solution until it is homogeneous.
A chemical vapour lock (adsorber) (7) is fitted on the metering
vessel to prevent ammonia vapours from escaping into the envi‐
ronment.
The metering pump (5) meters the ready-to-use ammonia solution
from the dosing tank at the corresponding point of injection (6).
Metering can be provided on-demand using external control of the
metering pump.
Optional fault indicating relays on the pumps can report faults on a
control panel.

10.3 Functional test with dilution water
Note for the operator
An explosive atmosphere can form in the supply
drum with concentrations of over 15% w/w and/or
high ambient and media temperatures. If a spark
jumps as the suction lance is approaching the
open opening of the supply drum, it could cause
this atmosphere to explode.
Therefore take appropriate measures, such as the
following:
–
Use an earthing cable to ensure that the suc‐
tion lance and storage tank have the same
potential just before inserting the suction lance
into the storage tank.
–
Use suction lances with a level switch with
explosion protection for Zone 0.
–
Only connect the ammonia water to the system
in its original drum or in an electrically con‐
ducting vessel.
1. Close the bottom stopcock on the metering vessel and con‐
nect the dilution water line.
2. Fill the dosing tank through the dilution water line up to the
maximum level - 120 l or 250 l marking, dependent on the
tank size.
3. Close the stopcock on the dilution water line.
4. Completely fill the test tank (empty ammonia water supply
drum) with rinsing water, e.g. condensate or deionised water.
25
Page 26
Start up
5. Check the operation of the “transfer pump” and check that it
switches off via the level switch in the metering vessel: Start
up the “transfer pump” using the green key
[Start filling metering vessel]
(is the multifunctional switch
turned to “External”?) and fill the metering vessel until the
level switch is triggered and the “transfer pump” stops. At the
same time, check the parts, such as the “transfer pump”, suc‐
tion line, the line to the metering vessel and the metering
vessel itself for leak-tightness. Finally close the stopcock
once more.
6. Functional test of the “metering pump": Switch on the
“metering pump” at the multifunctional switch and bleed the
liquid end - see "Operating instructions for solenoid metering
pump Beta® BT4b and BT5b". Check the leak-tightness of
the “metering pump”, metering line and injection valve and
their threads. Finally switch off the “metering pump”.
7. Check whether the suction line and the vapour recovery line
are fastened to the suction lance with hose clips. Ensure the
line connectors are securely seated and check for leaks.
8. Only with concentrations above 15% w/w: Take appropriate
measures to prevent a spark jumping to ignite the ammoniaair atmosphere when attaching the suction lance to the
storage tank.
9. Replace the test tank with a storage tank.
10. After commissioning the ammonia water metering system,
carry out one more complete visual inspection to ensure its
final safety.
The ammonia water metering system can now be handed over for
operation.

supervision, ammonia water solution can be
pressed out of the system.
– As batching is done in manual mode, the entire
process must be monitored from start to finish.
WARNING!
Hazardous ammonia vapours may escape.
Ammonia vapours will escape if the lid of the
dosing tank is open.
– The lid of the dosing tank must not and may
not be opened.
– The system must be shut down immediately
should the seal be missing on the lid and the
seal must be replaced by an authorised techni‐
cian.
CAUTION!
Only particle-free commercial ammonia water may
be used for batching.
Note for the operator
An explosive atmosphere can form in the supply
drum with concentrations of over 15% w/w and/or
high ambient and media temperatures. If a spark
jumps as the suction lance is approaching the
open opening of the supply drum, it could cause
this atmosphere to explode.
Therefore take appropriate measures, such as the
following:
–
Use an earthing cable to ensure that the suc‐
tion lance and storage tank have the same
potential just before inserting the suction lance
into the storage tank.
–
Use suction lances with a level switch with
explosion protection for Zone 0.
–
Only connect the ammonia water to the system
in its original drum or in an electrically con‐
ducting vessel.
Personal protective equipment
- always refer to the chemical supplier’s latest hazardous sub‐
stance data sheet and the latest regulations and materials safety
data sheets issued by the statutory accident prevention authorities.

Operation
Eye protection:
Adequate eye protection must be worn. Wear goggles. Use a protective shield if the face
is also compromised.
Hand protection:
Use safety gloves. The glove material must be sufficiently impermeable and resistant to
the substance used.
Protective clothing:
Depending on the level of risk, wear a sufficiently long apron and boots or an appropriate
protective chemical suit.
Respiratory protection:
Wear respiratory protection in exceptional situations (e.g. in the event of accidental
release of the substance, exceeding of the occupational exposure limit): Gas filter K,
green colour code (Germany). Note the limits on time of wearing!
Use an isolation unit with concentrations above the application limit of filter equipment,
with oxygen contents bellow 17 vol% or in the event of unclear conditions!

4. Open the dilution water stopcock (2) and fill the dosing tank
until half full.
WARNING!
The dosing tank needs to be filled with dilu‐
tion water to at least halfway – due to the
system’s internal explosion protection.
5. Open the bottom stopcock (5) on the metering vessel. Drain
any remains in the metering vessel through this stopcock into
the dosing tank.
The ammonia passes into the dosing tank through a pipe
ð
below the water level.
6. Start the “transfer pump” using the “Start filling metering
vessel” key.
It pumps ammonia water from the supply drum into the
ð
metering vessel (3).
The transfer pump level switch is triggered when the
maximum liquid level is reached**.

Operation
7. Open the bottom stopcock (5) on the dilution water metering
vessel.
The ammonia passes into the dosing tank through a pipe
ð
below the water level.
Steps 5 and 6 can be repeated several
times if the required final concentration
needs several top-ups of the metering
vessel.
WARNING!
Note the following to ensure that the
ammonia concentration in the dosing
tank remains below the explosion limit:
– With starting solutions of 25% w/w
ammonia in water:
A maximum of 6 top-ups of the
metering vessel can be added to the
“120 l” dosing tank.
A maximum of 5 top-ups of the
metering vessel can be added to the
“250 l” dosing tank.
This ensures that the maximum per‐
mitted metering solution of 2.5% w/w
is not exceeded. Correspondingly
more top-ups are needed with lower
starting solutions.
8. Open the stopcock (6) – briefly flush the metering vessel with
the dilution water and re-close the stopcock (6).
9. Wait until the metering vessel has emptied and then close
the stopcock (5).
10. Open the stopcock (2) for dilution water and allow as much
water to flow into the dosing tank until the required concen‐
tration has been reached.
WARNING!
Hazardous ammonia water solution may
escape
Overfilling can cause hazardous ammonia
water solution to escape.
– Fill the dosing tank at most up to the top
marking (120 l or 250 l marking)
11. Use the manual stirrer (4) to stir for approximately 15 s to
obtain a homogeneous solution.
12. Set the multifunctional switch on the “metering pump” to the
required frequency or to “External”.
The “metering pump” can now meter the diluted ammonia
ð
water into the application.
