3.4.1 Typical system Condair ME Control (internally mounted)

Fig. 4: Typical system Condair ME Control (internally mounted)

3.4.2 Typical system Condair ME Control (externally mounted)

Schematic flow diagram

Functional description
The water tank is filled up to a preset upper level via the level-controlled inlet solenoid valves (NC). When the water level in the water tank drops below a certain limit, the level-controlled inlet solenoid valves open until the upper limit is reached again.
The Condair ME Control provides On/Off or stage control by means of the Condair ME Control control unit and the stage pumps. The Condair ME Control control unit processes analog sensor/control signals and uses them to control the stage pumps.
In case of a humidification/cooling request with activated On/Off control the inlet solenoid valves (NC) opens and all stage pumps start and the water flows to the distribution headers above the evaporative cassettes.
In case of a humidification/cooling request with activated stage control the inlet solenoid valves (NC) open, then up to seven stage pumps start (depending on the demand signal and evaporative module size) and the water flows to the distribution headers above the evaporative cassettes.
The distribution pipes inside the distribution headers evenly supply the water to the entire surface of the evaporative cassettes where it flows down and humidifies the air flowing through the evaporative cassettes. The excess water not used for humidification flows to the water tank.
To prevent accumulation of mineral residues and the formation of germs in the water tank, the tank is completely drained periodically (interval or time controlled). Additionally further hygiene functions can be activated: Operation-dependent draining of the water tank (fill cycle, conductivity, temperature or time controlled).

General notes
The instructions and details regarding commissioning and operation must be followed and upheld.
The initial commissioning of the Condair ME Control requires appropriately trained technical personnel.
It is strongly recommended that your Condair representative commissions your system. Part of this initial commissioning process is a disinfection of the water tank, and if required the evaporative cassettes.
Please read this document in full before commencing any work.
Please pay attention to local regulations regarding working at heights and electrical work.
Safety and hygiene
DANGER!
The Condair ME Control must be operated in accordance with this manual. Failure to do so could result in contamination that might cause Legionnaires’ disease, which can be fatal.
WARNING!
The Condair ME control unit should not be electrically isolated for periods exceeding 24 hours as automatic drain and purge cycles will be disabled.
4.2 Initial commissioning
The initial commissioning of the Condair ME Control requires appropriately trained technical personnel. We strongly recommend that your Condair representative commissions your system.
Inspections
Prior to initial commissioning the complete system must be inspected for correct execution of the installations.
Proceed as follows:

1. Switch off AHU.

2. Evaporative module installation: Check correct selection of evaporative module on rating plate if multiple units on site. Check that the evaporative module has been installed level in all planes with secure blanking plates to prevent air bypass. Check that there is sufficient access for cassette removal during maintenance. Ensure assembly is securely fixed, and that there is no visible damage. Check that the evaporative module is installed in a waterproof section. Check evaporative module (including tank) is free of dirt/ debris and clean as necessary.

3. Control unit installation: Check that the control unit is mounted in a convenient dry location outside the AHU/air duct.

4. Supply water Installation: Ensure the water system in the building has been subject to a Risk Assessment. The Conair ME Control must be connected to a clean, wholesome mains water supply. It is the responsibility of the user to ensure that the water system complies with local regulations and bylaws, particularly those for the control of Legionella microbes. The use of mains water fed tanks and reservoirs is only permitted as part of a managed water treatment system. Check that the evaporative module has a feed water supply between 2 bar (29 psi) and 5 bar (73 psi) connected to the supplied approved filling hose. Ensure that any hygiene options have been correctly installed. Check all joints and fittings for leaks.

5. Drain installation: Check that the drain line is made according to the corresponding instructions given in the installation manual. Ensure the drain line is connected to the main building drain and that drain pipework is trapped to a suitable level for the applicable working duct pressure. Check all joints and fittings. Ensure that the drain connection includes an air gap.

6. Distribution pipework: Check all water distribution pipework between the hydraulic module and the distribution headers are securely fitted.

7. Electrical wiring: Check all electrical connections with reference to the corresponding wiring diagram in this manual. Check that a 100…240V / 10A single phase supply is connected to the control unit. Ensure that this power supply is isolated with an electrical isolator within 1 m (39″) of the control unit.

8. Optional controls: Check that appropriate controls connections have been made to the control unit. Refer to the controls wiring section of the installation manual.

9. Flush water supply and test supply water quality: Disconnect water supply pipes from connectors on both hydraulic modules. Fix hoses to open end of supply pipes and lead hoses to a drain outside the AHU. Carefully flush supply pipes a suitable amount of time without creating splashing or aerosols.
   Take a water quality sample to ensure that supply water meets the requirements specified in the water quality guide. The sample should be tested using a dip slide to indicate the total number of colony forming units per ml (cfu/ml). Generally, levels of 1×10 3 cfu/ml may be considered acceptable for this type of humidifier provided the species of microbes and/or fungi involved are themselves not considered to be harmful. If you are unsure of the quality of your water please consult your Condair distributor for advice.
   Then reconnect the water supply pipe to the supply connector on the hydraulic module.

10. Perform pressure test: Turn on water supply and check for leaks. Ensure shut off valve is installed correctly.

After the system has been inspected and found correct proceed with the initial commissioning:

1. Switch off AHU.

2. Switch on electrical isolator, and then the <Control unit On/Off> switch on the control unit.

3. Enter the activation code (see chapter 5.5.2).

4. Simulate full demand and check components are operating correctly.

5. Check correct water level and pump activation.

6. Check water can flow to drain correctly.

7. Test correct flow of water to distribution header.

8. Test any fitted options (see relevant option addendum manual).

9. If the evaporative cassettes had become dirty or damp prior to commissioning, follow the disinfection procedure described in chapter 6.3 and chapter 6.9 of this manual.

10. If the system is equipped with fibre media evaporative cassettes (F75, F85, F95, C85, C95) perform a matrix wash over cycle (see chapter 5.5.2).

11. Switch on fan of AHU and test operation with fans running and validate air conditions against the design data.

12. Test control devices.

13. Correctly configure Conair ME control unit (setpoints, control settings, etc.) according to the situation on site (see chapter 5.4).

14. Switch off AHU, and ensure AHU is locked-off to prevent it from starting.

15. Remove any demand from the ME system.

16. Drain the tank and wipe tank clean.

17. Perform disinfection:
    • Send a demand to the unit to make it fill and start running (the demand signal can be overridden for the duration of the disinfection using the “Disinfection Demand” function in the service menu (see chapter 5.5.2).
    • Set the duration of the disinfection period using the “Disinfection Duration” function in the service menu (see chapter 5.5.2). Ensure the disinfection period leaves sufficient time to neutralise the disinfectant if required.
    • Start disinfection process with the “Start Disinfection” function in the service menu (see chapter 5.5.2), to prevent the Condair ME Control draining the water tank during the disinfection process.
    • Add a disinfection chemical according to tank volume.
    • After the disinfection process has completed, neutralize disinfectant, if required.

18. Power cycle the Condair ME Control to remove the forced disinfection demand (allowing normal control to be resumed) and check correct control operations (signals, fault outputs, Modbus/BACnet).

19. If commissioning has not been completed by an approved Condair representative, it is recommended that records are kept of commissioning date and software settings.

20. Demonstrate system to customer and highlight hygiene and maintenance requirements.

21. Raise any installation concerns.

22. Issue commissioning documentation.

The system is now ready for normal operation.
4.3 Display and operating elements

DANGER!
Risk of electric shock!
There is still mains voltage inside the control unit even when you switch off the <Control unit On/ Off> switch. Mains voltage provides a risk of electric shock, therefore the electrical isolator must be switched off before opening the control unit. Only qualified personnel should carry out work within the ME control unit.
4.4 Start up for normal operation
It is assumed that initial commissioning has been carried out properly by the service technician of your Condair representative.
If the Conair ME Control has been out of operation for a prolonged period of time, a complete system service has to be performed prior to the start up.
The following description outlines the start up procedure for normal operation. Proceed as follows to prepare the Condair ME Control for operation:

1. Switch off AHU.

2. Examine the Conair ME Control for possible damage and faulty installation. Ensure tank is empty.
   DANGER!
   Damaged systems or systems with damaged components or faulty installations may present danger to life or cause severe damage to material assets.
   Damaged systems and/or systems with damaged or faulty installation must not be operated.

3. Close doors of AHU if open, then switch on AHU if switched off.

4. Open the shut-off valves in the water supply lines.

5. Make sure the front panel of the control unit is mounted and fixed with the retaining screw.

4.6 Decommissioning the system
In order to decommission the Conair ME Control (e.g. to perform maintenance works, to eliminate a malfunction, etc.) perform the following steps:

1. If the system has to be switched off because of a malfunction, please note the Warning and Fault code(s) of the actual error message(s) shown in the fault history.
2. Close the shut-off valves in the water supply line to the hydraulic modules.
3. Empty the water tank with the manual drain function (see chapter 4.5.4).
4. Switch off the <Control unit On/Off> switch on the control unit, and if necessary deactivate control unit via the external enable switch.
5. Disconnect control unit from the mains: switch off the electrical isolator in the mains supply to the control unit and secure switch in “Off” position against accidentally being switched on.
6. Let the fan of the ventilation system run until the evaporative module is dry.
7. If work has to be carried out on the evaporative module or the hydraulic modules mounted inside the duct, switch off the AHU and secure the system against accidentally being switched on.

Important Notes!

• If the Conair ME Control is in working order, then for hygiene reasons we recommend that the system should be left powered on, even if the Conair ME Control is not going to be used for a prolonged period of time. To prevent the Conair ME from humidifying/cooling set the “Operation” function in the service menu to “Off”. This keeps the hygiene functions (e.g. periodical flushing of water supply pipe) active and hence the build-up of bacteria is opposed.

DANGER!
If the Conair ME system is isolated from the mains power for a prolonged period, water stagnation might occur in the supply pipework, and microbial contamination of the supply pipework and  Conair ME system could result.

• If the Conair ME system is to be isolated from the mains for a prolonged period, then the ME system and any storage tanks or vessels should be drained and left dry. Before putting the system back in to operation, a full risk assessment should be undertaken to ensure safe operation, with particular attention paid to water supply quality. Additionally a complete system service has to be performed prior to putting the system back in to operation.

Maintenance

6.1 Important notes on maintenance
Qualification of personnel
All maintenance work must be carried out only by well qualified and trained personnel authorised by the owner. It is the owner’s responsibility to verify proper qualification of the personnel.
General notes
The instructions and details for maintenance work must be followed and upheld. Only carry out the maintenance work described in this documentation.
The Conair ME Control must be maintained in the prescribed intervals, the cleaning work must be carried out correctly.
For safety and warranty reasons, only use original spare parts from your Conair representative to replace defective parts or parts which have elapsed their lifetime.
Safety and hygiene
Some maintenance work requires removal of the unit cover. Please note the following:
DANGER!
Danger of electric hazard!
Before carrying out any maintenance work take the Conair ME Control out of operation as described in chapter 4.6 and secure the system against inadvertent power-up. In addition take AHU out of operation as described in the operation instructions of the AHU and secure the AHU against inadvertent power-up.
CAUTION!
The electronic components inside the control unit are very sensitive to electrostatic discharge. Prevention: Before carrying out any maintenance work to the electrical or electronic equipment of the control unit, appropriate measures must be taken to protect the respective components against damage caused by electrostatic discharge (ESD protection).
DANGER!
Health risk by inadequate maintenance!
Inadequately operated and/or poorly maintained adiabatic humidification/cooling systems may endanger health. When inadequately operated and/or poorly maintained, micro-organisms (including the bacterium which causes Legionnaire’s disease) may grow in the water system and in the area of the humidification unit and may affect the air in the AHU/air duct.
Prevention: the adiabatic air humidification /air cooling system Conair ME must be correctly operated as described in chapter 4, and must be correctly maintained and cleaned in the prescribed intervals as described in chapter 6.
DANGER!
Damaged systems / components may present a danger to life, or cause damage to material assets.
We advise that the customer routinely checks the system and components for damage. It is particularly important that the tank, structural components, and fixings (such as studs) are inspected as damage to these items could affect the structural integrity of the system. Please contact your local Conair representative immediately in the event of discovering damaged components.
6.2 Maintenance intervals
In order to maintain operational safety and hygienic demands the Conair ME Control must be serviced at regular intervals. The time interval for the complete system service is to be adapted to the operating conditions. The hygiene status depends mainly on the quality of the humidifier water but also on the adherence to the exchange intervals of the upstream air filter, the air velocity and the micro-biological and chemical composition of the supply air. Therefore the service intervals must be determined for each
system separately.
The interval time for a complete system service is to be determined at commissioning. The default is 2000 hours of operation.
Depending on the encountered hygiene status when performing a complete system service the interval time must be decreased or increased.
In any case the Conair ME Control system should receive a complete service at least once annually.
Note:
We recommend to perform a minor service between two complete system service.
The interval time for complete system service can be programmed on the control unit. To determine the interval time for a complete system service the above described procedure can be used. As soon as the maintenance time has elapsed, a maintenance message is displayed to draw your attention to the pending service.
6.3 Maintenance guide
The Condair ME unit will form part or your hot and cold water system and as such require you to undertake certain duties with regards to local regulations and bylaws concerning the control of Legionella microbes in water systems. Your water sampling / testing and disinfection regime must be based on results of a site specific risk assessment. If any further assistance is required or you are interested in a planned maintenance quote, please contact your Condair distributor.
Note: routine water sampling and testing is not included as part of a Condair service contract.
Please note that the information given in the table below is only to act as a guide which shows the work to be carried out on “Minor Service” and “Complete System Service”. Correct maintenance is vital to ensure optimum output, reliability and safety.

• Unsuitable surface and ground
• Other equipment, machinery or supply pipework in the vicinity of the work area

Maintenance of the ME unit must only be carried out by trained personnel, and all tools & equipment must be checked by a skilled and competent health & safety representative.
WARNING!
In the event of water carry-over from the evaporative cassettes or a water leak, surfaces near the ME system may have become wet. This could result in a slipping hazard or an increased risk when handling components. If this occurs, risk assess the situation and take suitable precautions before working on the ME system. If carry-over was the cause of any standing water in the AHU/duct, follow the advice in chapter 7.4 to remedy the problem.
6.4.1 Dismantling and installation of the evaporative module

1. Take the Conair ME Control out of operation as described in chapter 4.6 and allow to drain and dry.

2. Switch the AHU off, and isolate the power and water supply to the AHU.

3. Disconnect distribution hoses from the connectors on the distribution heads, the wall feed-throughs (if applicable) and the hydraulic module.

4. Remove droplet separator boxes (column by column):
   • Remove upper separator brackets.
   • Remove bank of separator boxes.
   • Remove lower separator brackets.

5. Remove distribution headers assemblies from topmost evaporative cassettes:
   • Undo the clamps fixing the distribution header assembly to the evaporative cassette.
   • Carefully lift off the distribution header assembly.

6. Remove evaporative cassettes (column by column):
   • Push box upwards and remove.

7. Remove optional UV lamp (if applicable).

8. Remove the cross bar (remember position).

6.6 Health and safety requirements
In accordance with local regulations, users must take water samples for Legionella analysis. Samples should be taken from the same places as described in chapter 6.7, and the analysis carried out by an accredited laboratory which is part of an appropriately certified Legionella testing scheme. In the event that the Legionella content exceeds 100 cfu/l, the humidifier should be switched off and specialist advice sought regarding its disinfection.

1. If biofilm (a slimy or gel-like deposit when wet, which might be dry and crisp in a dry system) is found during any inspection of the humidifier or water system, the humidifier MUST be switched off and not put back into operation until the system has been taken apart, scrubbed and thoroughly cleaned with a suitable biocide with biofilm penetrating qualities such as 50 ppm chlorine dioxide solution. This work should only be carried out by fully trained specialist organizations or individuals.
2. The control unit of the Conair ME Control must be left powered on to allow automatic flushing and cleaning cycles to occur. If the control unit Conair ME Control is powered off for prolonged periods, water stagnation might occur and contamination result, so the system, including any storage tanks or vessels should be drained and left dry. Before putting the system back into service, the water pipework supplying the Conair ME Control should be purged carefully, avoiding the creation of aerosols by splashing, and a water sample should be taken to ensure cleanliness. In the event that the humidifier pipework contains any residual water or has remained damp, and the temperature exceeded 20 °C (68°F), the Conair ME Control should be disinfected using an appropriate solution.

Contact your Conair representative for advice on water sampling and analysis, disinfection of systems, service and maintenance.

6.7 Routine water sampling and testing
Hygiene
Your attention is drawn to local regulations and bylaws regarding the control of Legionellosis in water systems. If inadequately maintained, water systems, of which any humidifier is a part, can support the growth of micro-organisms, including the bacterium that causes Legionnaires’ disease. Conair has considered all aspects of this equipment to reduce as far as possible the risk of Legionnaires’ disease and other similar conditions, but it is important that users are aware of their responsibilities under local regulations in reducing the risk of Legionellosis.
To prevent the growth of Legionella, users are required to:

1. Carry out a risk assessment of the water system using a competent person, and implement an appropriate monitoring and control regime.
2. Avoid water temperatures which favour the growth of Legionella.
3. Avoid water stagnation.
4. Clean and disinfect the system in accordance with local regulations and bylaws, and the instructions in this manual.
5. The Condair ME Control system must be connected to a clean, wholesome mains water supply and it is recommended that the supply water is chlorinated. It is the responsibility of the user to ensure that the water system complies with local regulations and bylaws, particularly those for the control of Legionella microbes. The use of mains water fed tanks and reservoirs is only permitted as part of a managed water treatment system.

On commissioning and at regular intervals thereafter, test for possible water contamination using dip slides.
Take samples from the water supply, the evaporative cassettes and from the tank. Check for biofilm.
The dip slides should be incubated for 2 days at 30°C (86°F).

1. If the microbial count from the tank exceeds 10 3 cfu/ml, the system should be turned off, any biofilm scrubbed clean and then disinfected using a 50 ppm chlorine solution for one hour before being put back into use.
2. If the microbial count in the water supply to the evaporative module exceeds 10 3 cfu/ml, this suggests contamination of the water system within the building. The system should be turned off and you should seek specialist advice on cleaning your water supply.
3. If the water temperature anywhere in the system regularly exceeds 20°C, (68°F) increase the frequency of water sampling. The frequency may be reduced if successive tests show a consistent level below 10 3 cfu/ml.

6.8 Cleaning and disinfection
Before commencing cleaning and disinfection:
At initial commissioning we recommend the use of a mild disinfection solution, which should be placed in the tank and circulated around the system.
Note: Start disinfection process always with the “Start Disinfection” function in the service menu (see chapter 5.5.2), to prevent the Condair ME Control draining the water tank during the disinfection process.
For systems in operation or where the water quality or air quality is poor, it is recommended to dismantle and scrub the system clean, to carry out a disinfection with a minimum of 50ppm chlorine or an appropriate disinfection solution circulated for 1 hour
minimum (or the time recommended by the disinfectant manufacturer if not using chlorine). Please refer to the cleaning and disinfection and method statement section to ensure that the relevant chemicals, equipment and Personal Protective Equipment are available to carry out disinfection.

1. A qualified person appointed by the customer must risk assess the cleaning and disinfection operation. This assessment should include but is not limited to observance of local regulations and the use of PPE, working from heights and ensuring a full understanding of the Condair ME Control.
2. Coordinate with relevant responsible persons.
3. Check records (i.e sample results of microbiological control) for system history.
4. If possible, disinfection should be carried out when the building is unoccupied, with air flow off.
   Evaporative humidifiers must be regularly cleaned and maintained, to prevent contamination especially in industrial environments.

All surfaces requiring disinfection or cleaning must be in contact with the appropriate concentration of disinfection solution for the correct contact period. The method statement for disinfection may need to be adapted depending on the layout of the humidifier pipework. Additional procedures will be required for supply water system pipework or water treatment systems prior to the humidifier.
Conair recommends that routine disinfection should take place in the following situations:

• At initial commissioning (for brand new systems use a mild disinfection chemical).
• At six monthly intervals as part of the maintenance regime.
• If the system or part of it has been shutdown and/or substantially altered creating a risk of contamination.
• During or following any increase of bacterial activity (as per recommendations in chapter 6.7) or outbreak or suspected outbreak of Legionellosis.

Recommended disinfection equipment

• Disinfection solution in accordance with manufacturers guidelines.
• Disinfection neutralizer (only if necessary).
• Disinfection solution test kit (to measure strength).
• Bucket of fresh water.
• Cleaning equipment.
• Mixing vessel / Measuring container.
• Risk assessment / test record sheets. Appropriate report/record
• Standard tools
•  Appropriate PPE
• COSHH risk assessment / MSDS

6.9 Cleaning and disinfection method statement
WARNING!
Disinfectants can be corrosive, toxic or irritant. Use of disinfectants may present a risk to health and could harm the environment.
Step 1 – Refer to the cleaning and disinfection risk assessment

• If the unit is already in operation, check for correct operation.
• Ensure the Condair ME system and the AHU are OFF and isolated.
• If the system has been without power for more than 48 hours, flush the water supply.
• Ensure the area is well ventilated.
• Refer to the manufacturers instructions and safety advice for chosen disinfectant.
• If there are concerns over the level of biofilm or bacteria in the system, disinfect the tank before starting cleaning work.
• Scrub tank fully. For more thorough disinfection remove droplet separator banks (if applicable) and the evaporative cassettes to allow better access to the tank (refer to maintenance section)
• Scrub hydraulic module inside fully. Also scrub inside the pump housings, clean the pump impellors, clean the level sensor, and clean the optional conductivity probe. Take care not to damage the level sensor or conductivity probe.
• Consider appropriate maintenance requirements at this time including parts replacement i.e. replacing distribution hoses to ensure that these are also disinfected.
• Re-assemble the Condair ME system (refer to installation manual).

Step 2 – Mix disinfection solution

• Mix disinfection solution following the manufacturers instructions. Recommended 50ppm Chlorine solution circulated for 1 hour minimum or appropriate time. NB: For larger or particularly unclean systems this process may need to be repeated.
• Calculate the total water volume of the system.
• Note: Solution loses strength over time and the solution may need to be increased through the process or the disinfection process may need to be repeated.

Step 3 – Run the unit

• Switch the control unit on.
• Send a demand to the unit to start it running (the demand signal can be overridden for the duration of the disinfection using the “Disinfection Demand” function in the service menu (see chapter 5.5.2).
• Set the duration of the disinfection period using the “Disinfection Duration” function in the service menu (see chapter 5.5.2). Ensure the disinfection period leaves sufficient time to neutralize the disinfectant if required.
• Start disinfection process always with the “Start Disinfection” function in the service menu (see chapter 5.5.2), to prevent the Conair ME Control draining the water tank during the disinfection process.
• Check that the evaporative cassettes become fully saturated, and the system is operating correctly.

Step 4 – Add disinfection solution

• Add the disinfection solution to the water tank and allow to flow through the evaporative cassettes.
• Measure the strength of the disinfection solution and check it is the correct strength in accordance with manufacturers guidelines.
• Note the strengths of the disinfection solution at 15 minute intervals and record on a record appropriately.
• Adjust solution strength as required.

Step 5 – Circulate disinfection solution

• Check all surfaces are wetted for desired time and correct solution.

Step 6 – Neutralize the disinfection solution – if required based on chemical used
WARNING!
If a neutralizing solution is required, always ensure that the neutralizing solution is used in accordance with the manufacturer’s guidance. Failure to follow the manufacturer’s guidance with regard to neutralizing the disinfection chemical may present a risk to health.

• Mix neutralizing agent as manufacturers instructions.
• Allow the neutralizing agent to disperse over the matrix and circulate in the tank.
• Drain and measure the strength as per MSDS until the disinfection solution is down to desired strength.

Step 7 – Drain the unit into foul drain

• Turn Off any fill cycle.
• Drain unit until empty into appropriate drain (depending on Risk Assessment) and rinse the tank if necessary.
• Fill and drain unit including flushing over the evaporative cassettes and test to ensure that the chemical is removed to the appropriate level.
• Wipe tank clean.
• *Where required, reset to original setting and put unit back into operation. Test for correct operation as per commissioning section of the manufacturers manual.

7.5 Notes on fault elimination

• For the elimination of faults set the Conair ME out of operation as described in chapter 4.6, disconnect control unit from the mains and close shut-off valve in the water supply line.
  DANGER!
  Make sure the control unit is separated from the mains (check with voltage detector) and the shutoff valve in the water supply line is closed.

• The elimination of faults must be carried out by qualified and well trained professionals only.
  Malfunctions relating to the electrical installation (e.g. replacement of the backup battery, replacement of fuses) must be repaired by authorized personnel (e.g. licensed electrician). or by your Conair representative’s service technician only.
  CAUTION!
  Electronic components are very sensitive to electrostatic discharge. When carrying out repairs to the control unit, appropriate measures (ESD- protection) must be taken to prevent damage to electronic components.

• Repair work and the replacement of faulty components must be carried out by your Conair representative’s service technician only!

7.6 Resetting the fault status on Conair ME Control
To reset the error indication:

1. Disconnect the control unit of the Conair ME Control from the mains.
2. Wait approx. 5 seconds, then reconnect the control unit to the mains.
   Note: If the fault has not been eliminated, the fault indication reappears after a short while.

7.7 Replacing the fuses and backup battery in the control unit
The fuses of the control unit must be replaced by authorized personnel only (e.g. electrician).
Replace fuses of the control unit only with fuses matching the specifications below with the appropriate nominal current capacity. Never use refurbished fuses. Do not bridge the fuse holder.
To replace the fuses or the backup battery proceed as follows:

1. Disconnect control unit from the mains by switching off the electrical isolator and secure electrical isolator in “Off” position against inadvertent switching on.

2. Undo the screw of the front cover of the control unit, then remove the front cover.

3. Open control unit inner door.

4. Replace desired fuse or the backup battery.
   DANGER!
   Fuse contact protection must be relocated after the fuse has been replaced.

5. Close control unit inner door.

6. Relocate front cover on control unit and lock it with the retaining screw.

7. Reconnect control to the mains by switching on the electrical isolator.
