INSTALLATION RECOMMENDATIONS FOR AHUThe area chosen for installation must allow for enough space around the unit for comfortably and safely carrying out installation andsuccessive maintenance operations, including the replacement of any internal component (e.g. removal of the heat exchange coils, thefilters, ) see figure.INSTALLATION RECOMMENDATIONS FOR VRV CONDENSING UNITSMake sure the space around the unit is adequate for servicing and the minimum space for air inlet and air outlet is available (refer to thefigure below and choose one of the possibilities). 13
›› In case of an installation site where sides A B C D have obstacles,the wall heights of sides A C have no impact on service spacedimensions. Refer to the figure above for impact of wall heights ofsides B D on service space dimensions.›› In case of installation site where only the sides A B have obstacles,the wall heights have no influence on any indicated service spacedimensionsINSTALLATION RECOMMENDATIONS FOR DX CONDENSING UNITSSpecial consideration must be given to location of the condensing unit(s) in regard to structures, obstructions,other units, and any/all other factors that may interfere with air circulation. Where possible, the top of the unitshould be completely unobstructed; however, if vertical conditions require placement beneath an obstructionthere should be a minimum of 1.5 meters between the top of the unit and the obstruction(s). The specifieddimensions meet requirements for air circulation only. Consult all appropriate regulatory codes prior todetermining final clearances.Another important consideration in selecting a location for the unit(s) is the angle to obstructions. Eitherside adjacent the valves be placed toward the structure provided the side away from the structure maintainsminimum service clearance. Corner installations are strongly discouraged.NOTRECOMMENDEDBBBOK!OK!BMinimum Airflow Clearance, CMinimum Airflow ClearanceModelTypeABCAA 14Residential10"10"18"20"
ControlsThe main components of a Daikin AHU are:›› Supply and return fast: Supply and return fans are used to regulate the air volume.›› Air filters: pre-filter and bag filter: Every AHU unit can be equipped with severaltypes of filters used to clean the air from little particles of dust etc.›› Device for heat recovery: These devices are used to recover cooling or heatingfrom the return air.›› DX coils: These are the devices used for air temperature conditioning.›› Electrical and Control Section: The AHU is equipped with electrical and controlssection for the power input to the supply fan, return fan and the controllersincluding the switchgear, control components, relays, etc.›› Field Sensors: To control the air handling units the required temperature andpressure sensors will be provided.Controller:Daikin offers maximum flexibility in the control and monitoring of
