The MK series ductless split systems are a matched combination of an outdoor condensing unit and an indoor fan coil unit connected only by refrigerant tubing and wires. The in -ceiling cassette fan coils are ideal for retrofit or modernization projects where a false ceiling is available. This selection of fan coils permits inexpensive and creative solutions to design problems such as: Add -ons to current space (an office or family room addition) pecial space requirements When changes in the load cannot be handled by the existing system. When adding air conditioning to spaces that are heated by hydronic or electric heat and have no ductwork. Historical renovations or any application where preserving the look of the original structure is essential. The ideal compliment to your ducted system when it is impractical or prohibitively expensive to use ductwork. These compact in -ceiling cassette units require less than 12 inches (304.8 mm) of false ceiling space and the only part that is seen is an aesthetically pleasing grille that blends with most decor. Advanced system components incorporate innovative technology to provide reliable cooling performance at low sound levels.

2 LOW OUND LEVEL When noise is a concern, the duct-free split 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. When sound ordinances and proximity to neighbors demand quiet operation, the 24AHA4/25HHA4/124AN/224AN unit is the right choice: The advanced, horizontal blow -through airflow design distributes air more evenly over the coil. ECURE OPERATION 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 24AHA4/25HHA4/124AN/224AN units can be installed close to an outside wall, coils are protected from vandals and severe weather. FAT INTALLATION This compact ductless split system is simple to install. A mounting bracket is standard with the indoor units and only wire and piping need to be 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 MK ductless split systems the equipment of choice, especially in retrofit situations. IMPLE ERVICING AND MAINTENANCE 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 through design of the outdoor section means that dirt accumulates on the outside surface of the coil. Coils can be cleaned quickly from the inside using a pressure hose and detergent. On all indoor units, service and maintenance expense is reduced due to easy -to -access cleanable filters. In addition, these cassette systems have extensive self-diagnostics to assist in troubleshooting. BUILT -IN RELIABILITY Ductless split system indoor and outdoor units are designed to provide years of trouble-free operation. The cassette indoor units include protection against freeze -up and high evaporator temperatures on heat pumps. The condensing units and heat pumps are also protected. There is a 3 -minute time delay before the compressor will re -start. An oversized accumulator, high pressure switches (or liquid line pressure switch on the heat pump), and compressor internal overload protection will ensure a reliable system that is ideal for light commercial applications. INDIVIDUAL ROOM COMFORT Maximum 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. ECONOMICAL OPERATION The ductless split 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 CONTROL The cassette units have microprocessor-based controls to provided the ultimate in comfort and efficiency. The user friendly wireless remote control provides the interface between user and the unit. FLEXIBILITY A variety of accessories simplify the installation process and help meet system requirements and weather conditions. ee table of available accessories on page 4.

15 APPLICATION DATA UNIT ELECTION The horizontal units are available as cooling only and heat pumps. For most applications, the cooling load dictates the size selection. elect equipment to either match or be slightly less than anticipated peak load. This provides better humidity control, fewer unit cycles, and better low load performance. For units used in spaces with high sensible loads, base equipment selection on unit sensible load, not on total anticipated load to avoid oversizing the equipment. UNIT MOUNTING (INDOOR) Unit leveling - For reliable operation, units should be level in all planes. Align and level the unit by adjusting the nuts and lock -nuts on the threaded hangers. Clearance - A minimum of 12 inches (304.8 mm) of clearance is required in the false ceiling. Unit location - Placing the unit in the center of the room will provide the best air circulation and comfort. The unit return and discharge should not be obstructed by anything which may cause unit short cycling or air recirculation. upport - Threaded hangers should be used to install the unit and the structure should provide adequate support for the weight of the unit. Mounting Template - Fan coil units are supplied with a cardboard template to help match the position of the hangers, refrigerant lines, condensate drain pipe and power supply cable. UNIT MOUNTING (OUTDOOR) Unit leveling - For reliable operation, units should be level in all planes. Clearance - Minimum clearance, as shown in Fig. 10, must be provided for airflow. The condensing units are designed for free-blow application. Air inlets and outlets should not be restricted. Unit location - A location which is convenient to installation and not exposed to strong wind. If the unit is exposed to strong winds it is recommended that a wind baffle accessory be used. A location which can bear the weight of outdoor unit and where the outdoor unit can be mounted in a level position.

When equipped with a Low Ambient Controller, the unit will operate down to -20_F (-28.9_C). For proper operation of colling only units, a Winter tart Kit (bypasses the Low Pressure witch), a Crankcase Heater (prevents refrigerant migration during compressor-off cycle), and a Wind Baffle should also be installed. On heat pumps, a Winter tart Kit will not be required. An Isolation Relay, to bypass the Low Ambient Controller when unit is in heating mode, is required. Metering Devices The metering device(s) for these systems is a type B accurator. The cooling accurator is installed with the indoor unit, while the heating accurator is installed with the outdoor unit. One Accurator is required for the cooling only system and two are required for the heat pump systems. Refer to following table for the accurator size.

A downward sloped condensate drain pipe can be used to dispose of water. 15

16 REFRIGERANT LINE General refrigerant line sizing: 1. Refrigerant lines should not be buried in the ground. If it is necessary to bury the lines, not more than 36 -in (914 mm) should be buried. Provide a minimum 6 -in (152 mm) vertical rise to the service valves to prevent refrigerant migration. 2. Both lines must be insulated. Use a minimum of 1/2 -in. (12.7mm) thick insulation. Closed -cell insulation is recommended in all long -line applications. 3. pecial consideration should be given to isolating interconnecting tubing from the building structure. Isolate the tubing so that vibration or noise is not transmitted into the structure. NOTE: ince the same outdoor unit can be matched with different types of indoor units, it may not have enough refrigerant charge. Refer to the Physical Data tables to determine if additional charge is required. Long Line Applications The minimum length between the indoor and outdoor units is 10 ft. (3m). Refer to the following table for the maximum lengths allowed.

CONTROL YTEM The unit is equipped with a microprocessor controls to operate the system and provide optimum levels of comfort and operating efficiency. The main microprocessor is located in the control box of the fan coil unit with thermistors located in the fan coil inlet and on the indoor coil. These thermistors monitor the system operation and control the operating mode. To change the settings or the modes of operation, use the factory supplied wireless remote control or accessory wired controller. The unit has 5 operating modes: Fan Only Auto (heat pump models only) Heating (heat pump models only) Cooling Dehumidification (Dry) FAN ONLY - In the Fan Only mode, the system filters and circulates the room air without changing the room air temperature. AUTO - In Auto mode, the system will automatically select one of the following operating modes: cooling, heating or fan only based on the difference between the room temperature and the set point temperature. HEATING - In the Heating mode, the system heats and filters room air. COOLING - In the Cooling mode, the system cools, dries and filters room air. DEHUMIDIFICATION (DRY) - in Dehumidification (Dry) mode, the system dries, filters and slightly cools room temperature. This mode does not take the place of a dehumidifier. In addition to the above modes that are selected by using the remote control. The unit can run in two other modes selected by the manual button: EMERGENCY RUN TET MODE EMERGENCY mode - is used when the remote control is misplaced or the batteries in the remote control have expired. Pushing the manual button under the front cover will put the unit in Auto mode with a predetermined set point (73.4_F/ 23_C). TET mode - is used when a technician needs to diagnose the unit for a malfunction. The unit can be set into TET mode using the remote control. It will run regardless of the set point. The microprocessor controls offer additional comfort and economy features like LEEP mode, TIMER and AUTO WEEP. Refer to the Owner s Manual for additional details on these features. UER INTERFACE The units come standard with a wireless remote control. The wireless remote has a range of 25 ft (8 m) when pointed toward the unit. For some applications (commercial), a wired remote may be more desirable. A wired remote control is offered as an accessory.
