The ideal compliment to your ducted system when it is impractical or prohibitively expensive to use ductwork. These compact indoor fan coil units take up very little space in the room and do not obstruct windows. The fan coils are attractively styled to blend with most room decors. Advanced system components incorporate innovative technology to provide reliable cooling performance at low sound levels. pecifications subject to change without notice.

2 LOW OUND LEVEL When noise is a concern, the ductless systems are the answer. The indoor units are whisper quiet. There are no compressors indoors, either in the conditioned space or directly over it, and there is none of the noise usually generated by air being forced through ductwork. EURE OPERATI If security is an issue, outdoor and indoor units are connected only by refrigerant piping and wiring to prevent intruders from crawling through ductwork. In addition, since outdoor units can be installed close to an outside wall, coils are protected from vandals and severe weather. FAT INTALLATI This compact ductless system is simple to install. A mounting bracket is standard with the indoor units and only wire and piping needs to run between indoor and outdoor units. These units are fast and easy to install ensuring minimal disruption to customers in the home or workplace. This makes the ductless systems the equipment of choice, especially in retrofit situations. IPLE ERVIING AND AINTENANE Removing the top panel on outdoor units provides immediate access to the control compartment, providing a service technician access to check unit operation. In addition, the draw thru design of the outdoor section means that dirt accumulates on the outside surface of the coil. oils can be cleaned quickly from inside using a pressure hose and detergent. On all indoor units, service and maintenance expense is reduced due to easy to use cleanable filters. In addition, these cassette systems have extensive self diagnostics to assist in troubleshooting. BUILT IN RELIABILITY Ductless system indoor and outdoor units are designed to provide years of trouble free operation. The in ceiling cassette units include protection against freeze up and high evaporator temperatures on heat pumps. The condensing units on heat pumps are protected by a three minute time delay before the compressor starts the over current protection and the high temperature protection. INDIVIDUAL ROO OFORT aximum comfort is provided because each space can be controlled individually based on usage pattern. The air sweep feature provided permits optimal room air mixing to eliminate hot and cold spots for occupant comfort. In addition, year round comfort can be provided with heat pumps. EOIAL OPERATI The ductless system design allows individual room heating or cooling when required. There is no need to run large supply air fans or chilled water pumps to handle a few spaces with unique load patterns. In addition, because air is moved only in the space required, no energy is wasted moving air through ducts. EAY TO UE TROL The in ceiling cassette has microprocessor based controls to provide the ultimate in comfort and efficiency. The user friendly wireless remote control provides the interface between user and the unit. FATORY INTALLED DENATE LIFT PUP ustomizing these ductless systems to your application is easily accomplished. The factory installed condensate lift pump on the cassette fan coil unit provides installation flexibility.
