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.
Important notes on operation Qualification of personnel The Condair ME Control must be commissioned and op erated only by personnel familiar with the sys- tem and adequately qualified for the respective tasks. It is the owner’s responsibility to verify proper qualification of the operating personnel.
Initial commissioning The initial commissioning of the Condair ME Control may only be carried out by Condair authorized and appropriately trained technical personnel. Inspections Prior to initial commissioning the complete system must be inspected for correct execution of the instal- lations.

• After the disinfection process has completed, neutralise 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.
If the control unit is switched off all functions (including hygiene functions) of the Con- dair ME are deactivated (see DANGER note blow). Fig. 13: Display and operating elements Condair ME Control DANGER! Risk of electric shock! There is still mains voltage inside the control unit even when you switch off the control unit via the <On/Off>...
It is assumed that initial commissioning has been carried out properly by the service technician of your Condair representative. If the Condair 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 Condair ME is switched on and under voltage "Furnace" Not supported! 4.5.3 Recommended regular checks during operation During operation the Condair ME Control has to be checked periodically in accordance with the table below. Operations Checks Daily Weekly Monthly...
Water level is correct (ensure unit is not in drain cycle) If the checks reveal any irregularities (e.g. leakage, error indication) or any damaged components take the Condair ME Control out of operation as described in Section 4.6. Then, have the malfunction elimi- nated or the damaged component replaced by a well trained specialist or a service technician from your Condair representative.
4.5.5 Performing a matrix wash over At initial commissioning when the "W49 - Matrix Wash Over" warning message appears or any time new fibre evaporative cassettes have been installed, a matrix wash over cycle has to be performed. If a matrix wash over cycle is required proceed as follows: Note: The "Matrix Wash Over"...
If the Condair ME Control is in working order, then for hygiene reasons we recommend that the system should be left powered on, even if the Condair ME Control is not going to be used for a prolonged period of time. To prevent the Condair ME from humidifying/cooling set the "Operation" function in the "Maintenance >...
Operating the Condair ME control software Home screen After switching on the control unit and the automatic system test the control unit is in normal operating mode and the home screen is shown. Note: the appearance of the home screen depends on the current device and error status and the con- figuration of the humidity/temperature control of the system.
After the demand has dropped to zero, the system drains a small amount of water to give space to the water running out of the matrix. Drain Check The Condair ME is draining the tank and uses the first section of the drain procedure to check whether the drain valve is working properly. Bleeding During operation the stage pumps are stopped periodically to bleed any air out of the pumps by the water flowing back from the distribution pipes.

Dismantling and installation of components for maintenance WARNING! A full risk assessment must be completed by suitably trained personnel prior to carrying out mainte- nance of the ME unit. There may be increased risk when carrying out maintnenance on systems that necessitate working at height.
6.4.1 Dismantling and installation of the evaporative module 1. Take the Condair ME Control out of operation as described in Section 4.6 and allow to drain and dry. 2. Switch the AHU off, and isolate the power and water supply to the AHU.
This work should only be carried out by fully trained specialist organisations or individuals. 2. The control unit of the Condair ME Control must be left powered on to allow automatic flushing and cleaning cycles to occur. If the control unit Condair ME Control is powered off for prolonged periods, water stagnation might occur and contamination result, so the system, including any stor- age tanks or vessels should be drained and left dry.
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 sup- ply 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.
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.
• Start disinfection process with the "Manual Disinfection Start" function under "Menu > Engineer- ing password > Maintenance > Manual Disinfection", to prevent the Condair ME Control draining the water tank during the disinfection process. •...
Page 64
Add a mild disinfectant chemical to the tank. • Always leave work area clean, dry and tidy. Step 8 - Re-start the Condair ME system • Refer to the commissioning section of this manual. If in doubt always contact your Condair distributor.
6.10 Resetting the maintenance counters After completing the Condair ME system maintenance, after replacement of the optional UV lamps or after replacement of the optional PureFlo cartridge, the corresponding maintenance indication or maintenance counter, respectively must be reset. Proceed as follows to reset the maintenance counter:...
6.11 Performing a software update To update the control software of the Condair ME or the firmware of one of its electronic boards, proceed as follows: 1. Set the <On/Off> switch on the right side of the control unit to the Off position, then switch off the voltage supply to the control unit via the external electrical isolator and secure switch in the Off posi- tion to prevent it from inadvertent power up.
Fault elimination Fault indication Malfunctions during operation detected by the control software are indicated by a corresponding Warn- ing message (Status LED lights up yellow and the exclamation mark symbol is displayed in the device and error status field of the home screen) or Error message (Status LED lights up red and the cross symbol is displayed in the device and error status field of the home screen).
Note: Remedial measures highlighted in gray in the malfunction list may only be remedied by a Condair service technician or a service center authorized by Condair. If applicable, contact your Condair repre- sentative.
