1 40 KMC / 38 HDF40 KMQ / 38 QRFIn --- Ceiling Cassette Duct --- Free Split SystemSizes 018 to 036 Product DataThe ideal compliment to your ducted system when it is impracticalor prohibitively expensive to use LEADINGFEATURES / BENEFITSAN INEXPENSIVE AND CREATIVESOLUTION TO DESIGN 38 HDF(QRF) / 40 KMC (KMQ) series duct--free split systemsare a matched combination of an outdoor condensing unit and anindoor fan coil unit connected only by refrigerant tubing and in--ceiling cassette fan coils are ideal for retrofit ormodernization projects where a false ceiling is available. Thisselection of fan coils permits inexpensive and creative solutions todesign problems such as:SAdd--ons to current space where the existing systemcannot handle the space requirements. like a conference room,where the load compact in--ceiling cassette units require less than 12 inches( mm) of false ceiling space and the only part that is seen isan aesthetically pleasing grille that blends with most SOUND LEVELSFor applications like conference rooms or libraries where noise is aconcern, the in--ceiling cassette is the answer.

2 The indoor units arewhisper quiet. There are no compressors indoors, either in theconditioned space or directly over it, and there is none of the noiseusually generated by air being forced through sound ordinances and proximity to neighbors demand quietoperation, the 38 HDF/QRF unit is the right choice: The advanced,horizontal blow--through airflow design distributes air more evenlyover the OPERATIONIf security is an issue, outdoor and indoor units are connected onlyby refrigerant piping and wiring to prevent intruders from crawlingthrough ductwork. In addition, since 38 HDF/QRF units can beinstalled close to an outside wall, coils are protected from vandalsand severe INSTALLATIONThe small footprint of the outdoor unit provides additionalbenefits. Because they require minimal service and airflowclearances, the outdoor units can be located virtually anywhere --on the ground, roof, balcony, under a deck, or even mounted on anoutside compact in--ceiling cassette requires less than 12 inches ( ) of false ceiling and the 40 KMC018 unit fits into a 2 X 2 ( m X m) false units are fast and easy to install ensuring minimal disruptionto customers in the workplace and making them ideal for SERVICING ANDMAINTENANCES aving time and money was a big consideration when designingthese the indoor unit, opening the grille will allow a servicetechnician access to the control box and to remove the cleanablefilters.

3 There is even a plug to drain water from the condensate panif it is ever the outdoor unit, a single panel provides immediateaccess tothe isolated compressor and control compartment, allowing aservice technician to check the unit operation without a loss ofcondenser airflow. In addition, the blow--through design of theoutdoor section means that dirtaccumulates on the inside surfaceof the coil. Coils can be cleaned from the outside using a pressurehose and detergent without removing grilles or using fin RELIABILITYDuct--free split system indoor and outdoor units are designed toprovide years of trouble--free in--ceiling cassette units include protection against freeze--upand high evaporator temperatures on heat condensing units and heat pumps are also protected. There isa 3--minute time delay before the compressor will re--start. Anoversized accumulator, high and low pressure switches (or liquidline pressure switch on the heat pump), and compressor internaloverload protection will ensure a reliable system that is ideal forlight commercial ROOM COMFORTM aximum occupant comfort was key in the design of thein--ceiling cassette instance, the indoor unit is equipped with a motorized louversystem that provides optimum air distribution into the conditionedroom.

4 The user can select eight different louver operating modesto adjust the airflow according to their specific air can be distributed from four sides of the unit. This allowsthe unit to be installed in the center of the room. For applicationswhere the unit has to be installed near a wall or in a corner, aspecial kit is available to close one or two heat pumps, the controls have built--in features to automaticallycompensate for air stratification and avoid cold blow on start--up orduring OPERATIONThe duct--free split system design allows individual room heatingor cooling when required. There is no need to run large supply--airfans or chilled water pumps to handle a few spaces with uniqueload patterns. In addition, because air is moved only in the spacerequired, no energy is wasted moving air through CONTROLSThe in--ceiling cassette units have microprocessor--based controlsto provided the ultimate in comfort and efficiency.
