1.4 Safety Precautions
1.4.1 Sulphuric Acid
Sulphuric acid can cause severe chemical burns and injuries.
First aid measures Electrolyte on the skin: Dab off the acid using a cotton or paper towel, do not rub it off. Rinse the affected parts under run­ning water for a longer time. Remove soaked pieces of clothing beforehand. In doing so, preferably avoid contact with body parts that are not affected. After rinsing, wash thoroughly using soap.
Electrolyte in the eye: Rinse the eye under running water or use the eyewash bottle. Avoid excessive water pressure. Consult an ophthalmologist immediately.
Electrolyte in the body: Immediately consult a doctor or go to a hospital. Until the doctor arrives: depending on degree and location of the chemical burn, rinse with magnesium oxide suspension, or drink it. If available, also use water with dissolved bicarbonate (sodium carbonate).
Also see ZVEI leaflet “Safety data sheet for battery acid (diluted sulphuric acid)” in the annex.
1.4.2 Explosive Gases
An explosive mixture of hydrogen/oxygen can escape from lead acid batteries. In case of an explosion of the mixture, severe personal injuries can occur.
- Always wear the prescribed protective clothing (safety goggles, suitable protective gloves and safety boots, see chapter 1.3).
- Use proper tools only (not “striking sparks”, with insulated handles etc.).
- Prevent any ignition sources such as sparks, flames, and electric arcs.
- Prevent electrostatic discharge, wear cotton clothes and ground yourself if necessary if you
are working directly on the batteries.
In case of fire, only use water or CO2 to extinguish it!
Danger!
Switch off the battery charging voltage first!
During extinguishing work, use a respirator with independent breathing air supply. Do not point the fire extinguisher directly on the battery (batteries) to be extinguished. There is a risk that the battery housing will crack due to thermal tension.
Moreover, there is a risk of explosion due to possible static charges on the battery surface.
In order to minimise electrostatic charges on the battery surface, extinguish at short intervals. There is a risk of explosions due to possible static charges on the battery surface.
Toxic gases might occur when plastic materials are combusting. In this case, leave the fire ground as soon as possible if you are not wearing a respirator.
When using extinguishing water/foam, there is a risk of a short circuit.
When using extinguishing water, there is a risk of reactions with the electrolyte and, as a conse­quence, severe squirting. Therefore, wear acid-proof protective clothing.
1.4.3 Electrostatic Discharges
All lead acid batteries develop hydrogen and oxygen gas, known as oxyhydrogen, during operation but mainly during charging. These gases are escaping from the batteries into the surroundings of the battery. For the natu­ral or technically supported ventilation which always has to be provided, you have to assume that an ignitable hydrogen-oxygen gas mixture is only present in the vicinity of the battery cell openings. An ignitable hydrogen-oxygen gas mixture is always present inside the battery housing itself. This applies inde­pendent of the battery technology, design or manufacturer and is typical for all lead acid batteries. The energy which is required for the ignition of oxyhydrogen is very low and can, for example, be released or introduced as follows: Open flames or fire, smouldering sparks or flying sparks during grinding work, electrical sparks due to switches or fuses, temperature > 300 °C and – an often underestimated cause – electrostatic discharges.
Measures to prevent oxyhydrogen ignitions due to electrostatic discharges
The development of electrostatic discharges on the battery or on your body or your clothing can be prevented if you observe the following:
Do not wipe the battery with a dry cloth, in particular cloth made of synthetic materials! Rubbing on plastic surfaces (battery housings are usually made of plastic) generates electrostatic charges.
Clean the battery surfaces only with cotton cloths which are moistened with water. No charges develop when wiping with a damp cotton cloth.
When working on batteries, you must prevent your clothes (e.g. made of wool) from rubbing on the battery. This could cause the development of electrostatic charges on the battery housing or your body or clothes.
Wear suitable shoes and clothes which prevent the occurrence of electrostatic charges due to their special surface resistivity. This can prevent the development of electrostatic charges on your body or clothes.
Do not remove labels on the battery without special safety precautions. Pulling or tearing plastic labels off plastic surfaces can cause electrostatic charges which can ignite oxyhydrogen when discharging.
Before removing the label, wipe the battery with a wet cloth.
According to EN50272-2, the following requirements apply to the battery room: The floor area in which a person is within arm’s reach to the battery must be conductive in such a way that electrostatic charging is avoided. The leak resistance to a grounded point measured according to IEC 61340­4-1 must be less than 10 Mohm. On the other hand, the floor must be sufficiently insulated for the protection of persons. Therefore, the leak resistance of the floor against a grounded point measured according to IEC 61340-4-1 must be: For battery voltages ≤ 500 V: 50 kohm ≤ R ≤ 10 Mohm; For battery voltages > 500 V: 100 kohm ≤ R ≤ 10 Mohm.

2 Functional Principle of the aquagen
When using the aquagen recombination system, the oxyhydrogen mixture which develops during the water decomposition in the battery is led to the aquagen recombinator. This gas is recombined by means of an inte­grated catalyst with water vapour developing during the process. The water vapour condenses at the walls of the aquagen recombinator. The developing water drops flow down and are returned to the battery. Depending on the conditions, the efficiency of this recombination is up to 99%. This effectively reduces the efforts for the refilling of water. We recommend a visual inspection of the electrolyte level at least twice per year. Due to the recombination of the developing gases, the ventilation requirements according to EN 50272-2 can be reduced significantly.
For battery cells/ blocks with a capacity of max. 500 Ah C10 or when using NiCd-battery cells at a capacitiy of max. 450 Ah C5, it is possible to use the grid | aquagen the grid | aquagen

Aquagen recombinators may only be operated with HOPPECKE batteries (closed construction/ VLA).
Attention!
3 Assembly of the aquagen
Before starting to work in the battery room, you must ensure that the ventilation is operative. In case of technical ventilation, it must be switched on while working on the batteries.
Danger!
Observe all aforementioned safety instructions and safety precautions, in particular with regards to the leak resistances of gloves and safety boots (see chap. 1.3) as well as the floor area in the
Danger!
Danger!
battery room (see chap. 1.4.3).
Before attaching the aquagen recombinator, and if the electrolyte level has fallen to the “min.” mark during the operation of the battery system, the electrolyte level has to be restored by refilling cleaned/desalinated water (DIN 43530 part 4/IEC 60993-1). Overfilling beyond the “max.” mark must be avoided.
3.2 Inserting the aquagen
If the aquagen is mounted on older batteries, it is necessary to replace the old battery plugs with a bayonet plug.
Aquagen products with visible damages caused by falling, collisions or similar must not be used.
Attention!
The aquagen is vertically inserted into the correspondingly prepared bayonet plug (Figure 1), and is pressed into the bayonet plug until reaching the stop by means of slight rotary movements (Figure 2). Now, the aquagen is fully mounted (Figure 3).
Figure 1: Inserting the aquagen I
Figure 2: Inserting the aquagen II
3.1 Removing the labyrinth insert using screwdriver
In order to loosen the labyrinth insert from the bayonet plug, a screwdriver gets inserted between the labyrinth insert and the bayonet plug and pulled off towards the top while pressing on the bottom edge. After the labyrinth insert is loosen from the bayonet plug, it can be picked up with the hand.
Attention, there might be electrolyte residues on the labyrinth insert. The labyrinth inserts should be placed and later stored in a suitable container.

4 Removing the aquagen
If the aquagen has to be removed, e.g. for disposal, you have to proceed in accordance with the instructions in this chapter.
If the battery is supposed to be operated without the aquagen recombination system for a longer time than necessary for maintenance purposes, the ventilation has to be shifted from the possibly

Danger!
reduced air volume flow to the air volume flow required by EN 50272-2.
In case of boost charges with high currents, the surface of the aquagen recombination system can heat up strongly. Avoid touching the aquagen recombination system in this operating phase – risk of injuries! Moreover, dark deposits might develop on the walls in case of boost charges. These deposits do not impair the functionality of the aquagen recombination system.
If the bayonet plug is not directly accessible (e. g. power.bloc OPzS, OGi bloc 12V) the aquagen recombinator can be lifted with a dedicated lifting tool Mat.-No. 7149004000. Note: The aquagen needs to be removed from the battery opening immediately after loosening.
After loosening, the
aquagen
must be removed from the battery opening immediately.
Danger!
Deposit the aquagen together with its bayonet plugs into a suitable container in order to collect electrolyte residues.
The aquagen must be stored in a vertical position so that remaining fluids can drain off without
Attention!
obstructions, and the active material in the aquagen remains dry.
4.1 Maintenance
Normally, the aquagen recombination system does not have to be removed from the batte­ry cells for maintenance purposes. All current HOPPECKE lead acid battery cells in closed/ VLA design are equipped with a so-called service opening (except block batteries e. g. OGi bloc or power.bloc OPzS), via which it is possible to measure the temperature and acid density, as well as to refill water. Contact your local HOPPECKE representative if you need further information about accessory products.
Before the disassembly, ensure that most of the fluid collected in the recombinator drains off downwards by slightly knocking on the housing of the aquagen. In order to remove the aquagen from the battery, the aquagen – together with its bayonet plugs – is loosened by turning it counter-clockwise and then lifted off from the cell.
During maintenance work, the aquagen must never be placed loosely in the (battery) cell opening!
Danger!
Always carry out cleaning work before or after the replacement using only cotton cloths (without synthetic components) which were moistened with water.
Danger!
For the subsequent assembly, please proceed according to chap. 3.2 “Inserting the aquagen”.
4.2 Disposal
Dispose of the aquagen according to chapter 4.1. At first, deposit the aquagen in a cardboard box with an open top. Do not close the box! Because the aquagen might contain acid residues, the legal provisions on the disposal which are applicable in the country of destination must be observed. Please also observe the recom­mendations regarding disposal and handling in the safety data sheet on sulphuric acid. Please contact your local HOPPECKE representative if you want HOPPECKE to dispose of the aquagen recombinator.
In general, do not use plastic sacks or bags in the vicinity of the battery.

5 Capacity and Service Life
Aquagen recombinators are overload-proof, i.e. there is no risk of the plastic materials of the aquagen recombinator or the battery being damaged due to overheating for voltages up to
2.7 V/cell (boost or equalisation charges with I const). The function of the recombiner will be not
restricted in this case. The aquagen recombiner is optimized in the working range up to 2,4 V and achieves the highest efficiency and the maximum service life.
For cyclic applications, we therefore recommend the use of the HOPPECKE electrolyte-circulating pump sun.air instead of the aquagen recombinator. When using the aforementioned pump, it is also possible to reduce the water consumption significantly.
Explanation: Boost charges and equalisation charges: charges with I/U curve, voltage limitation at max.
2.4 V/cell in the constant voltage phase.
An initial charge is also a boost charge. It is realised with an I/U curve with a max. voltage of
2.4 V/cell. As an alternative, it is also possible to charge with an I- (constant current) or a
W- (constant power) curve. In doing so, charging voltages of up to 2.6 V/cell are reached.
Before charging with voltages > 2.4 V/cell, we recommend the removal of the aquagen recombi­nators. In order to avoid contaminations of the caps of the battery cells/blocks, the bayonet plugs

Attention!
with the labyrinth inserts have to be inserted into the cell openings before beginning to charge.
When charging with higher currents over a corresponding period of time, condensation of water vapour outside the aquagen recombinator might occur. The water drops which will develop in this case are not an indicator of a fault or a leakage in the system.
If aquagen recombinators are, for whatever reason, removed from the cells/blocks, the aquagen recombinators must be deposited in a vertical position by analogy with the operating position (do not place recombinators on the side). A corresponding tray “aquagen Stand” is included in the scope of delivery.
If the ambient air temperature at the installation location of the battery can drop below 5 °C, aqua­gen recombinators must not be assembled or operated. Otherwise openings inside the aquagen might freeze and hence gas can not escape from the cell anymore. In consequence the battery cell jar might be damaged due to excess pressure.
