2. Safety instructions

Non-observance of the safety instructions may have dangerous consequences for persons, the environment and the product.

2.1 Working with chemicals

WARNING

Chemical hazard

Death or serious personal injury

- Wear the stipulated personal protective equipment (protective clothing, goggles, respirator etc.) when handling chemicals.

- Observe the chemical manufacturer's safety data sheets (MSDS) and safety instructions of the used chemicals.

Make sure, that parts in contact with the chemicals are resistant to the chemicals under operating conditions.

If you have questions regarding the material resistance, please contact Grundfos.

Make sure, that leaking chemicals do not cause personal injury or damage to property.

The installation of leak monitoring equipment and drip trays is recommended.

2.1.1 Personal protective equipment

Due to the variety of hazardous chemicals, any information provided in this section is only general. We recommend to follow good practice when handling chemicals, to use personal protective equipment such as ventilated, enclosed goggles, face shields, chemical aprons, boots and gloves, and to install an eye shower.

2.1.2 Sodium hypochlorite solution

The concentration of the sodium hypochlorite (NaClO) solution produced by the Selcoperm electrolysis system is below 1 %.

CAUTION

Corrosive substance

Minor or moderate personal injury

- Sodium hypochlorite is alkaline and causes oxidisation and bleaching. It is corrosive and can cause damage to skin or clothing.

- Always wear protective clothing and goggles when handling chemicals.

• If splashed onto skin, wash off with fresh water. Remove all affected clothing.

• If the eyes are affected, rinse them immediately using an approved eye shower or fresh running water for at least 15 minutes, keeping the eyelid open and rotating the eye. Seek medical treatment immediately.

• If swallowed, do not induce vomiting. Keep the patient warm and quiet and seek immediate medical help. If the patient stops breathing, apply rescue breaths and cardiopulmonary resuscitation as necessary, until medical help arrives.

Warning notices advising users of the possible dangers should be prominently displayed wherever sodium hypochlorite is stored, generated or handled.

WARNING

Chemical hazard

Death or serious personal injury If acid is mixed with sodium hypochlorite solution, highly hazardous chlorine gas is released.

- Keep acid away from the sodium hypochlorite solution and the degassing and storage tank.

- Display a warning notice locally.

2.1.3 Hydrogen gas

The electrolytic process of converting brine into sodium hypochlorite (NaClO) solution generates hydrogen gas, which is diluted and lead to a safe external discharge point by means of forced ventilation. The degassing and storage tank as well as all vent piping should be regularly checked to ensure that no gas leakages occur.

WARNING

Danger of explosion

Death or serious personal injury

- When checking the system for gas leakages, use hydrogen detectors. Do not use a match or a flame.

Hydrogen is an explosive gas and lighter than air. When liberated in a room, hydrogen accumulates beneath the ceiling. Ensure natural ventilation at a high and a low level in the room where the electrolyser is installed.

A sign that prohibits smoking and naked flames must be displayed in the room and at the point of discharge to the exterior.

A gas warning system for hydrogen must be installed at the installation location to stop the Selcoperm electrolysis system in case of a build-up of hydrogen gas. This avoids the situation of a user working in a potentially explosive environment.

The rectifier converts the alternating current (AC) from the power supply into the direct current (DC) needed to run the Selcoperm electrolyser.

In the degassing and storage tank the hydrogen gas is removed from the sodium hypochlorite solution. The degassing and storage tank must be installed as close as possible to the Selcoperm electrolyser. The level in the tank is monitored by a level sensor. The degassing fan ensures a safe dilution and removal of hydrogen gas. The sodium hypochlorite solution can be dosed directly from the tank to the point of application. It is also possible to pump the sodium hypochlorite solution from the tank into separate storage tanks.

The gas warning system monitors the concentration of hydrogen gas at the installation location permanently.

Natural ventilation via ventilation holes or technical ventilation is required at the installation location. Legal requirements and local standards must be observed.

2 Brine line

Sodium 3

hypochlorite

solution line

4 Exhaust air line

Besides the sodium hypochlorite solution this line contains hydrogen gas, which is removed in the downstream degassing and storage tank.

Through this line the dilution air (99 %) and the hydrogen gas (1 %) are removed from the degassing and storage tank by means of forced ventilation. The exhaust air line has to be directed with a constant upwards incline to a safe discharge point outside the building.

5 Sodium hypochlorite solution line to the point of application

- Drain A drain for maintenance is required on site.

4.1.5 Safety concept

This section refers to fig. 2. A reliable safety concept for the operation of the whole system is

mandatory, because hydrogen is produced as a by-product in the electrolysis cells.

Before even entering the degassing and storage tank (G), most of the hydrogen is diluted by the degassing fan to 25 % of the lower explosive limit (LEL) and led away into the atmosphere. In the tank, the residual hydrogen is released, diluted and led away into the atmosphere.

The whole Selcoperm electrolysis system is monitored permanently and redundantly. Several sensors at the system, together with hydrogen sensors at the installation location ensure a safety shutdown of the whole system in the event of a failure. Small amounts of hydrogen, which can escape due to a leakage, are led away via the ventilation hole (I) at the highest point of the room.

The safety concept is evaluated with technical report by a third-party expert from TÜV SÜD Product Service GmbH. It ensures safe operation without any additional explosion protection at the installation location.

Conformity with ATEX directive

The ATEX directive covers devices that can be used in a potentially explosive atmosphere and/or may contain a potentially explosive atmosphere. However, the ATEX directive is only applicable, if the device has a potential source of ignition in its internal zoned area.

The Selcoperm system has internal zoned areas, but the ignition sources inside the system have been eliminated by design. The Selcoperm system is not intended for operation in a potentially explosive atmosphere. Therefore, the Selcoperm system is not subject to the ATEX directive and must not be ATEX marked. A declaration of conformity in accordance with the directive is not applicable.

The following guidelines and standards have been applied:

• Machinery Directive 2006/42/EC

• EN ISO 12100 for the risk analysis

• DIN EN 1127-1 and DIN EN 13463-1 for the identification of explosion hazards and ignition sources

• (EX-RL) BGR 104, TRBS2152 and DIN EN 60079-10-1 for zoning and security measures

Furthermore, the explosion safety is ensured by several measures.

Explosion protection by avoiding the explosive zones:

• Preventing or limiting inside the unit – Redundant level sensors to ensure liquid filled parts

• Preventing or limiting to the facility – All connections are designed as permanently technically

sealed according to DIN EN 1127-1:2011 Appendix B and

TRBS 2152 Part2 2.4.3 – Design with flange, glue or weld connection – Organisational measures by 100 % FAT leakage test,

Explosion Protection by avoiding ignition sources

• An ignition source analysis and earthing concept was carried

out for the system. All ignition sources inside the system were eliminated by design. During operation, cells and piping of the system are filled with liquid. No electrical or moving mechanical components are implemented. Sensors that affect an explosive area are used as ATEX sensor.

Safety Facts

• Unique safety concept, evaluated with technical report by a

third-party expert from TÜV SÜD Product Service GmbH

• Technically permanently sealed components and thus no zone

in the installation room

• Ignition sources inside the system eliminated by design

• Artificial ventilation to dilute H

by-product inside the system

– Redundant monitoring of the ventilation system (fan & flow) – Pressureless system; no valves after the cells; dangerous

pressure build-up is impossible.

– High quality standard: Every Selcoperm electrolyser is

checked for 100 % performance and tightness at the factory

– Direct pipe-to-product degassing tank with level switches

(cell outlet & tank inlet) to ensure filled lines and electrode fluid level. No gas accumulation.

– Alarm and safe automatic shutdown of the installation in

case of an error, e.g. drop of flow for dilution

– Redundant safety including a gas detection system

combined with ventilation inside the building

Acceptance test by TÜV is possible for a complete system installed on site.

Labelling recommendations

English (GB)

A warning sign must be placed on the outside of the degassing and storage tank near the manhole. The purpose of the sign is to warn people of an explosive atmosphere, so that they can take the necessary precautions.

We recommend that the sign is accompanied by a written notice, e.g. "Permanently technically sealed system, during process zone 2 inside, outside no external zones".

Fig. 3 Label for degassing and storage tank

An additional sign must be placed near the exhaust air outlet of the building to inform people of the zone radius.

4.1.7 Process description

English (GB)

This section refers to fig. 5.

General information

The number of electrolysis cells in a Selcoperm electrolyser depends on the SES type:

SES type Cells inlcuded

SES-5000, SES-7500 C1.1 SES-10000, SES-15000 C1.1, C1.2 SES-20000, SES-30000 C1.1, C1.2, C2.1, C2.2 SES-45000 all cells as shown in fig. 5

Figure 5 shows the PID of the largest system which includes an electrolyser type SES-45000 with 6 electrolysis cells. The functional principal described here also applies to smaller systems with less electrolysis cells.

The soft water for the Selcoperm electrolyser is connected to soft water inlet (A). The soft water enters the system via shut-off valve (V0.01) and passes through pressure reducing valve (V0.02) to ensure a regulated pressure in the system.

The brine supplied by brine dosing station (BDS) is connected to brine inlet (B) and passes shut-off valve (V0.10). The brine dosing station (BDS) is usually equipped with 2 brine pumps (DP0.10) and (DP0.11). Only 1 brine pump is used for production while the other pump is in standby mode. The system can be configured to alternate between the 2 pumps each time production is started or in case the used pump fails. For simplification the following description only refers to brine pump (DP0.10).

The degassing and storage tank (DST) can optionally be equipped with a second standby degassing fan (EF4.02). The system can be configured to alternate between the 2 degassing fans each time production is started or in case the used fan fails. For simplification the following description only refers to degassing fan (EF4.01), which is included in each system as a standard.

Production process

When the system starts production, degassing fan (EF4.01) on degassing and storage tank (E4.05) is switched on. Once the exhaust air flow sensor (4.13) measures the correct flow rate, solenoid valve (0.05) opens and brine pump (DP0.10) is started. The soft water passes flow sensor (0.02) and is mixed with the brine in static mixer (V0.05). The resulting electrolyte passes flow sensors (1.10, 2.10, 3.10) and adjusting valves (V1.01, V2.01, V3.01) before it enters the electrolysis cells via 3-way valves (V1.02, V2.02, V3.02). The level switches (1.09, 2.09, 3.09) signal to the PLC that the electrolysis cells are filled. As soon as level switch (4.04) signals to the PLC that the NaClO (sodium hypochlorite) solution line is filled, the rectifier (REC) switches on the DC power supply for the cells (C1.1, C1.2, C2.1, C2.2, C3.1, C3.2) to start the electrolysis. The temperature switches (1.01 -

1.04, 2.01 - 2.04, 3.01 - 3.04) monitor the temperature of the DC connections on the cells.

The temperature sensor (0.03) monitors the temperature of the NaClO solution before it passes outlet (V). The NaClO solution contains a certain amount of hydrogen gas, which is produced as a by-product in electrolysis. It is led through a horizontal or slightly upwards inclining line into the degassing and storage tank (E4.05). Before entering the tank, the NaClO solution passes the T-piece (TP) to separate the hydrogen gas. The separated hydrogen gas is immediately diluted with air from degassing fan (EF4.01) to 25 % of the LEL. The exhaust air is led away through exhaust air outlet (T) to a safe external discharge point. The correct air flow in the exhaust air line is monitored by air flow sensor (4.13). In addition, the frequency converter of the degassing fan is used to monitor the fan speed.

When the NaClO solution reaches the stop-fill level in the tank measured by level sensor (4.10), the process is stopped. First, the DC power supply from the rectifier (REC) to the electrolysis cells is switched off. Solenoid valve (0.05) stays open, and brine pump (DP0.10) keeps running to flush the lines and cells with electrolyte for a few minutes.

After flushing is completed, brine pump (DP0.10) stops and solenoid valve (0.05) closes. The flow of electrolyte through the electrolysis cells stops. The degassing fan (EF4.01) stops after a few minutes. The system switches into "Standby" mode.

Additional monitoring equipment

The gas warning system (H2S) with two hydrogen sensors (5.01,

5.02) measures the concentration of hydrogen at the installation location. If hydrogen is detected, the gas warning controller (5.00) sends a signal to the PLC in the control cabinet (CTR) of the Selcoperm electrolyser to shut down the system.

The level switch (0.01) detects liquid in the Selcoperm electrolyser housing.

The level switch (4.03) detects liquid in the collecting tray of tank (E4.05).

Dosing of produced NaClO solution

The NaClO solution can be dosed directly from tank (E4.05) via solution outlet (U) to the point of application. It is also possible to pump the NaClO solution from tank (E4.05) into separate storage tanks.

Sampling

A sample of the NaClO solution can be taken from sample outlet (X) via sample valve (V0.09). A sample of the electrolyte entering the electrolysis cells can be taken at sample outlet (Y) via sample valve (V0.06).

Draining

After the system has been flushed and switched off, it can be drained via drain outlet (Z) using drain outlet valve (V0.08) and 3-way valves (V1.02, V2.02, V3.02).

Acid cleaning

For acid cleaning of the electrodes within the electrolysis cells, an external acid cleaning station can be connected to (C). Acid cleaning must be done according to section 9.5 Acid cleaning.

Operation and supervision

All components and safety functions are monitored and operated via a multi-colour touchscreen on the Selcoperm electrolyser (SES). If a fault occurs, the system stops and a message is displayed on the touchscreen.

4.3 Rectifier

The rectifier converts the alternating current (AC) from the power supply into the direct current (DC) needed to run the Selcoperm electrolyser. In case of a failure, the rectifier shuts down. The communication between the Selcoperm electrolyser and the rectifier is designed redundantly (Profinet and hardwired) for the safety shutdown functions.

4.4 DC cable set

The DC cable set contains the flexible insulated copper cable for direct current connection between the Selcoperm electroyser and the rectifier. The standard cable length must not exceed 10 m. Longer cables are available on request.

4.5 Degassing and storage tank

The degassing and storage tank is a mandatory component of the Selcoperm electrolysis system. In systems with several electrolysers, one tank for each electrolyser must be installed.

The minimum volume of the tank depends on the capacity level of the Selcoperm electrolyser.

The sodium hypochlorite solution can be dosed directly from the tank to the point of application. In this case, the volume of the tank must be selected according to the demand of sodium hypochlorite solution of the individual application. It is also possible to pump the sodium hypochlorite solution from the degassing and storage tank into separate storage tanks provided by the customer.

One degassing fan is installed on the tank by default. To avoid a system shutdown due to a defective fan, an additional standby fan can be installed.

4.5.1 Installation set

A special installation set is pre-installed on the degassing and storage tank. The use of this installation set is mandatory to ensure the compliance with the certified safety concept of the Selcoperm electrolysis system.

4.6 Brine dosing station

English (GB)

The brine is dosed with digital dosing pumps. To ensure reliable brine dosing, the dosing station comprises a duty pump and a standby pump. Pulsation dampers ensure low pulsation. As the counterpressure of the Selcoperm electrolyser is too low, the brine dosing station contains a pressure loading valve. Pressure relief valves ensure safe operation in case the pressure limit is exceeded.

The dosing station is controlled via the touchscreen on the Selcoperm electrolyser. A Flow Monitor is installed on each pump to monitor the dosing process. Errors in the dosing process are displayed on the touchscreen of the Selcoperm electrolyser.

The Selcoperm electrolyser provides the brine dosing station with the supply voltage and the control current.

4.7 Water softener

The water softener provides the softened mains water required for the electrolysis.

The water softener is equipped with a dual head and two cylinders to ensure a constant soft-water supply even during regeneration. A stand-alone brine tank provides the brine needed for regeneration. A pipe installation set, a bypass valve and a filter with manual backwash function are delivered with each water softener.

The water softener can be delivered pre-assembled on a skid or without skid.

Fig. 15 Water softener

4.8 Chiller

If the required soft water temperature cannot be met, a chiller can be used to cool the soft water down. The chiller is placed between the water softener and the Selcoperm electrolyser. The softened water entering the chiller must comply with the recommended soft water quality. See section 5.1 Selcoperm Electrolysis System

(SES). The chiller must be designed according to the local

system requirements and must be controlled via a separate control panel.

TM06 2223 3615

4.9 Heater

If the required soft water temperature cannot be met, a heater can be used to warm the soft water up. The heater is placed between the water softener and the Selcoperm electrolyser. The softened water entering the heater must comply with the recommended soft water quality. See section 5.1 Selcoperm

Electrolysis System (SES). The heater must be designed

according to the local system requirements and must be controlled via a separate control panel.

4.10 Brine tank

The brine tank is used for preparation and storage of brine.

TM06 2224 3615

4.11 Acid cleaning station

The acid cleaning station is pre-assembled on a trolley for acid cleaning of the electrodes. Acid cleaning shouldn’t be required more often than every two years during maintenance, unless there is a softening fault, or the quality of the used water or salt is poor.

The Selcoperm electrolyser provides the acid cleaning station with the supply voltage by means of a special plug. The acid cleaning station is controlled via the touchscreen on the Selcoperm electrolyser.

6.2 Installation requirements

The safety of the overall system is only guaranteed, if the installation requirements are strictly adhered to.

All installation work must only be carried out by qualified and authorised persons.

Separate the system from the power supply before working on the system components and lines.

Wear the stipulated personal protective equipment. Grundfos accepts no liability for any damage

resulting from incorrect installation.

6.2.1 Installation location

• The installation location must be free of vibrations.

• The installation location must be protected from rain, humidity, condensation, direct sunlight and dust.

• The installation location must be sufficiently illuminated to ensure safe handling of the system.

• The installation location must be in a solid building.

• Observe the permissible ambient conditions. See section

5.1.3 Ambient conditions.

TM06 2227 3815

6.2.2 Foundation and space requirement

For the installation of the system, provide a solid concreted surface, suitable for the weight and dimensions of the system.

Install the system on a horizontal foundation. Maximum slope: 1:200

Observe the maximum floor load. The foundation must be based on a sufficiently

bearing ground.

Make sure all components are always easily accessible for operation and maintenance.

For details on weights, dimensions and space requirement, see section 5. Technical data.

6.2.3 Water supply

The quality of the filtered water must comply with the specifications in section 5.1.1 Water quality specification. If the pressure is insufficient, a booster pump is required. If the produced sodium hypochlorite is dosed into drinking water, final treated mains water should be used.

For flow rates see section 5. Technical data. The tables do not include the water demand for water softener regeneration.

The water supply connections must comply with the respective international standards, e.g. double non-return valves on the inlet connection.

6.2.4 Connective pipework

Make sure that all pipes and fittings of your installation are suitable for drinking water. All electrolyser connections are made of PVC-U as a standard. All pipework should be made of PVC-U. We recommend to use black PE pipes and fittings for the outdoor vent piping, because of their higher resistance to UV radiation.

Use glued connections or flanges for the PVC pipework. For correct sealing of glued connections, prepare the surfaces with a proprietary solvent cleaner and use a proprietary PVC glue.

Use flanges to connect the PVC pipework to the PE pipework. Prior to installation, check all pipework and fittings between the

components for conformity with the local and international legislation.

6.2.5 Selcoperm electrolyser

Before installation, the housing parts must be removed in a certain order. See section 6.3 Dismantling and reassembling the

Selcoperm electrolyser housing.

Make sure the Selcoperm electrolyser is levelled out horizontally and fixed to the foundation using the levelling foots.

Make sure the ventilation holes on the top and bottom of the electrolyser are not covered during operation.

Hydraulic and electrical connections

Observe section 6.4 Electrical connection. For SES 5000-15000 all hydraulic and electrical connections are

covered by panel (60). See fig. 27. For SES 15000-45000:

• All hydraulic connections and the electrical DC connections are covered by panel (60).

• The signal connections, earthing connections and the power supply connection of the control cabinet are covered by bracket F (46).

See fig. 28. For details on hydraulic connections see sections:

• 4.1.6 Piping and Instrumentation Diagram (PID)

• 4.2.3 Overview of components

• 4.2.4 Overview hydraulics SES-5000 to SES-15000

• 4.2.5 Overview hydraulics SES-20000 to SES-45000.

Some pre-assembled mechanical and hydraulic connections in the Selcoperm electrolyser are loosened for transport. Make sure all connections are tightened before commissioning.

Water supply

The Selcoperm electrolyser must be supplied with softened water according to the specifications. See sections:

• 5.1 Selcoperm Electrolysis System (SES)

• 5.2 Selcoperm electrolyser.

6.2.6 Rectifier

6.2.7 Brine dosing station

Observe the separate documents delivered with the system.

6.2.8 Water softener

Observe the separate documents delivered with the system.

6.2.9 Brine tank

The brine tank must be supplied with softened water according to the specifications in section 5.10 Brine tank.

Avoid a temperature drop between the brine tank and the electrolyser, because this may result in crystallisation of salt.

6.2.10 Building ventilation

Natural ventilation via ventilation holes or technical ventilation is required at the installation location. Legal requirements and local standards must be observed.

The air supply for the degassing fan of the degassing and storage tank has to be taken into account when dimensioning the building ventilation.

6.2.11 Drain

An on-site drain for maintenance is required. The discharged water may contain chemicals, for example from

acid cleaning. Local regulations for the disposal of chemicals must be observed.

6.2.12 Gas warning system

As a part of the safety concept, a gas warning system for hydrogen gas (H

A self-contained gas warning system with at least two sensors for each Selcoperm electrolyser must be used. The gas warning system must have two potential-free output contacts, which are directly connected to the Selcoperm electrolyser to shut down the whole system in case of gas leakage. The contact type of the output contact must be NC (normally closed) to ensure the safety shutdown even in case of wire breakage.

• One sensor should be placed above the degassing and storage tank.

• One sensor should be placed at the highest point of the installation room.

) must be installed at the installation location.

English (GB)

Observe the separate documents delivered with the system.

The rectifier has special ambient conditions. See section

5.1.3 Ambient conditions. Observe the following:

• We recommend to install the rectifier in a separate room that meets the special ambient conditions.

• The standard DC cable length from the rectifier to the Selcoperm electrolyser is limited to 10 m. For longer DC cables contact Grundfos.

• The power loss of the rectifier leads to an increase of the ambient temperature in the installation room. Ensure sufficient air conditioning.

• Observe the technical data of the used rectifier. See section

5.3 Rectifier.

– For air-cooled rectifiers a sufficient air flow must be ensured

in the installation room.

– For water-cooled rectifiers a sufficient cooling water flow

must be ensured.

• The degassing and storage tank must be installed as close as possible to the Selcoperm electrolyser.

• The degassing and storage tank must be placed in a collecting tray with leakage detection.

• The overflow level of the degassing and storage tank must not be higher than 10 m above the foundation level of the Selcoperm electrolyser. Otherwise the pressure inside the system exceeds the limit.

• Details on components and connections see sections:

– 4.5 Degassing and storage tank – 4.1.6 Piping and Instrumentation Diagram (PID).

• If separate storage tanks for the NaClO solution are used, the aeration of these tanks must be piped to a safe discharge point outside the building. The storage location of the separate tanks must comply with the ambient conditions of the Selcoperm system. See section 5.1.3 Ambient conditions.

The piping of the degassing and storage tank comprises the sodium hypochlorite solution line and the exhaust air line (see fig.

2, pos. 3 and 4).

For the installation observe the following:

• The piping must be directed horizontally or with a constant slight upwards incline to a safe discharge point (T) outside the building. This is crucial for the safety of the whole installation, because it ensures that no hydrogen can accumulate in the lines. Hydrogen is much lighter than air and therefore rises in the horizontal or inclining lines to the safe discharge point, even if the forced ventilation fails.

• The piping must be installed as direct and straight as possible, with no dips and no more than 10 m in length. For longer distances ask Grundfos for suitable solutions.

– Only smooth bends should be used to avoid turbulent air

flow:

• Do not install shut-off valves in the NaClO solution line and in the exhaust air line.

• Do not install additional equipment (sensors, level switches etc.) in the NaClO solution line and in the exhaust air line.

• Do not make any additional openings (blind plugs, connections etc.) in the NaClO solution line and the exhaust air line.

• The venturi nozzle (VN) must be placed close to the wall duct with the hose connection on top to avoid ingress of condensate. The exhaust air flow sensor (4.13) should be placed further down, easy to reach for maintenance.

• Install the venturi nozzle (VN) according to section

6.2.14 Connection of venturi nozzle (VN) and flow sensor (4.13)

• The outlet (T) of the exhaust air line must be protected against blockages such as nesting birds without restricting the air flow.

Checking the level switches

1. Make sure, that the system and subsequent piping is filled with electrolyte so that the level switches detect liquid. If there is not enough electrolyte in the system:

– Activate solenoid valve (0.05) and brine pump (DP0.10) by

pushing the symbols until a sufficient liquid level is reached. The NaClO sample valve (V0.09) can be opened during filling until liquid escapes. This indicates a sufficient filling level.

– Deactivate solenoid valve (0.05) and brine pump (DP0.10)

by pushing the symbols.

The LEDs (1) on all level switches should light up.

2. Switch all 3-way ball valves (V1.02, V2.02, V3.02) to drain position.

Fig. 35 3-way ball valve in drain position

3. Open drain outlet valve (V0.08) until air is visible in the top electrolysis cells and close it again.

The LEDs (1) on all level switches must be off.

Adjusting the level switch (with filled piping)

If LED (1) is off:

1. Turn adjusting screw (2) clockwise until LED (1) lights up.

2. Turn adjusting screw (2) clockwise by 0.5 to 1 additional revolution.

If LED (1) is on:

1. Turn adjusting screw (2) counter-clockwise until LED (1) switches off.

2. Turn adjusting screw (2) counter-clockwise by 1 additional revolution.

3. Turn adjusting screw (2) clockwise until LED (1) lights up.

4. Turn adjusting screw (2) clockwise by 0.5 to 1 additional revolution.

7.2.6 Checking and adjusting NaClO level switch (4.04)

30°

English (GB)

The level switch is installed on the T-piece (TP) in the NaClO solution line. To check the level switch, electrolyte must flow through the T-piece.

1. Activate solenoid valve (0.05) and brine pump (DP0.10) by pushing the symbols.

– Electrolyte starts flowing through the system. – Wait until the electrolyte passes level switch (4.04) and

reaches the degassing and storage tank (DST).

• The sensor indicates the electrolyte flow with an integrated

LED:

– No electrolyte flow detected: LED on – Electrolyte flow detected: LED off

• On the display of the Selcoperm electrolyser, a small dot near

the level switch symbol indicates the electrolyte flow:

– No electrolyte flow detected: Dot is white. – Electrolyte flow detected: Dot is blue.

• If the level switch (4.04) is adjusted correctly and electrolyte is

flowing through the system, the LED on the level switch is off and the dot near the switch symbol is blue. This means: Liquid is detected.

2. Deactivate solenoid valve (0.05) and brine pump (DP0.10) by pushing the symbols.

– The electrolyte flow is stopped and the residual electrolyte

flows from the T-piece into the degassing and storage tank.

– Within approximately 15 minutes the LED on the level switch

lights up and the dot near the switch symbol turns white. This means: No liquid is detected.

Adjusting the level switch with filled piping

7.3 Switching to operation mode "Automatic"

The electrolyte that has entered the degassing tank during the first commissioning steps does not contain any NaClO. Only after switching to operation mode "Automatic" the system starts producing NaClO solution. Therefore the concentration of the NaClO solution in the tank may not reach the full 0.8 % immediately after commissioning.

In operation mode "Automatic" the system produces NaClO solution. The process starts by filling up the system with electrolyte. The level of electrolyte in the electrolysis cells and in the NaClO solution line is monitored. This ensures, that the DC current supply of the cells is only switched on after the cells and the line are filled with electrolyte. As soon as cells and line are filled, the small white dot near the respective level switch symbol turns blue. See section 8.5.7

1. Make sure all commissioning tasks are performed in the described order and finished. See sections:

• 7.1 Checks before commissioning

• 7.2 Starting up the system initially.

2. Open menu "System overview".

The starting procedure depends on the level of NaClO solution in the degassing and storage tank.

3. If the tank level is below 20 %: – Push [ ].

4. If the tank level is above 20 %: – Push [ ] and start production manually by pushing [ ]. – The system activates the different components with certain

time delays. For details see section 8.5.35 Start and stop

delays.

. Then the system stops the different

components with certain time delays. For details see section

8.5.35 Start and stop delays. After a short time the small blue dot

near level switch symbol (4.04) turns white. This indicates that the rest of the NaClO solution in the line is drained into the tank and the T-piece is empty.

The system is in operating state "Standby", until the level in the tank falls below the defined minimum level. Then it starts production again.

7.4 Checking the alarms

English (GB)

9.1 Safety instructions

The basic maintenance tasks must be performed by trained users.

The advanced maintenance tasks must only be performed by certified service persons.

Shut down the whole system before any work on the system components and lines.

Separate the system from the power supply before any work on the system components and lines.

Wear the stipulated personal protective equipment (protective clothing, goggles, respirator etc.).

Observe the chemical manufacturer's safety data sheets (MSDS) and safety instructions of the used chemicals.

Safety installations, which have been disabled or removed during maintenance, must be enabled or installed again immediately after maintenance.

Before starting any work in the ATEX zone, stop the Selcoperm system and wait until the degassing fan stops.

WARNING

Electric shock

Death or serious personal injury Liquids on electrical components can lead to electric shock. Furthermore damage to the equipment can be caused by short circuits.

- Keep all electrical components dry.

- Cover electrical components during maintenance with a watertight foil.

9.2 Special tools

9.2.1 Test kit

Test kit for SES, comprising:

• Measuring cylinder

• Total hardness test for titrimetric determination of the water hardness

• Thermometer

• Spindle for specific gravity measurement

• Titration set for measurement of the chlorine concentration in the sodium hypochlorite solution

• Operating instructions.

Fig. 75 Test kit

Description

Test kit 98842487

Product number

TM06 8498 0717

CAUTION

Chemical hazard

Minor or moderate personal injury Sodium hypochlorite solution tends to emit chlorine gas.

- When working with open tanks or lines, wear appropriate personal protective equipment.

When the Selcoperm system is stopped via the control panel or via external contact, the degassing fan continues running for some minutes. This ensures the removal of residual hydrogen gas from the system, lines and degassing and storage tank.

Wait until the degassing fan stops before starting any work on the system, lines and degassing and storage tank.

If the power supply was switched off or in case of power failure, wait at least 20 minutes before starting any work on the system, lines and degassing and storage tank.

Rinse removed parts with clean water. Before reassembling make sure, that all parts are

clean, dry and undamaged.

9.3 Basic maintenance schedule (users)

In the following table, the basic maintenance activities to keep the system free from troubles and avoid breakdowns are described. These activities must be performed by trained users. The intervals for some of the tasks depend on the individual installation and must therefore be defined by the operating company.

If the result of a check requires change, repair or adjustment of the system, call certified service persons.

9.5.1 Interval for acid cleaning

The acid cleaning process should only be performed, if significant scale has built up on the electrodes in the electrolysis cells. How fast scale builds up on the electrodes depends on the quality of the softened water and the salt.

Scaled electrodes lead to an increased DC voltage of the electrolysis cells. If the DC voltage has increased, check the water and salt quality and consider to perform an acid cleaning. An improper working water softener can also cause the need for an acid cleaning.

9.5.2 Performing the acid cleaning

This task must be performed by certified service persons.

A safe process control is only guaranteed, if the original Grundfos acid cleaning station with special plug connection to the Selcoperm electrolyser is used.
