At initial commissioning or any time new fibre evaporative cassettes have been installed, a media wash over cycle has to be performed.

  • Page 56: Modbus Communication

    Modbus Communication System status data can be read from the controller using Modbus RTU protocol via a RS485 connection to the terminals at J15 of the MC Control board. Jumper JP2 (TERM) only has to be set for the last devices in the net (end of line termination at the beginning and end of the Modbus network).

  • Page 57: Decommissioning The System

    – If the Condair MC is to be isolated from the mains for a prolonged period, then the MC and any stor- age tanks or vessels should be drained and left dry, the pumps should be removed from the hydraulic module to ensure all water is drained from the pump housings.

  • Page 58: Maintenance

    The instructions and details for maintenance work must be followed and upheld. Only carry out the maintenance work described in this documentation. The Condair MC must be maintained in the prescribed intervals, the cleaning work must be carried out correctly.

  • Page 59: Maintenance Intervals

    Maintenance intervals In order to maintain operational safety and hygienic demands the Condair MC 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.

  • Page 60: Maintenance Guide

    Maintenance guide The Condair MC unit will form part or your hot and cold water system and as such require you to un- dertake 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.

  • Page 61: Dismantling And Installation Of Components For Maintenance

    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 MC unit. There may be increased risk when carrying out maintenance on systems that necessitate working at height.

  • Page 62: Dismantling And Installation Of The Evaporative Module

    Dismantling and installation of the evaporative module 1. Take the Condair MC 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.

    2. The control unit of the Condair MC must be left powered on to allow automatic flushing and cleaning cycles to occur. If the control unit Condair MC is powered off for prolonged periods, water stagnation might occur and contamination result, so the system, including the pump housings and any stor- age tanks or vessels should be drained and left dry.

  • Page 65: Routine Water Sampling And Testing

    4. Clean and disinfect the system in accordance with local regulations and bylaws, and the instructions in this manual. 5. The Condair MC 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.

  • Page 66: Cleaning And Disinfection

    1. A qualified person appointed by the customer must risk assess the cleaning and disinfection opera- tion. 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 MC. 2. Coordinate with relevant responsible persons.

  • Page 67: Cleaning And Disinfection Method Statement

    If the unit is already in operation, check for correct operation. – Ensure the Condair MC system and the AHU are OFF and isolated. – If the system has been without power for more than 48 hours, flush the water supply.
