The valves is controlled by the system controller7.1 INSTALLATION7.1.1 LOCATION OF GMUInstall the Probe Cleaning Box as close as possible to the probe. Make sure that probe canbe removed from process without disconnection of flexible hoses7.1.2 AIR SUPPLYThe Probe Cleaning Box is to be connected to the main air supply by a buffer air tank. Thetank should provide pressure control and air punch to ensure sufficient filter cleaning. TheFLS Utillity Air option is recommended.Connection from eg. Utillity Air to Probe Cleaning Box should be done in standard piping'sby the customer.Connect the air supply according to the installation drawings.7.1.3 CABLING BETWEEN GAS MONITORING UNIT AND OTHER EQUIPMENTCables must be connected according to section “Cable list” in this manual.8 MAINTENANCE8.1 GENERALThe analysis system must be maintained and checked daily, the following sections containsmaintenance sheets for each unitTo ensure optimal drift and highest possible run time, the equipment should be serviced byan authorised service engineer. The service interval can vary from 1-4 times pr. year.Please contact us at the email address or telephone mentioned below for:· Proposal for a specific service agreement for the present equipment, 24h or normalcontract· Preventive maintenance according to technical documentation· Technical support· Immediate service at breakdown8.2 SPARE PARTSWear parts and recommended spare parts are listed in a section of the parts list. To ensurethat the correct part is delivered when ordering spare parts, please provide FLSmidth Airloqwith the project number which is found on the “System Data Sheet” and the FLSmidth PartNo. (6 digit) or Parts Id / Int. No.8.3 MAINTENANCE PROBEDuring the first few weeks of operation it is important to check the system every day, inorder to get to know the system and the applications in which it is installed and perhaps doadjustments if any.Always keep equipment clean outside and inside.
