MBDQ Ducted tyle Ductless ystem izes to Product Data INDUTRY LEADING EATURE / BENEIT A PERET BALANE BETWEEN BUDGET LIMIT, ENERGY AVING AND OMORT. The MBDQ series ducted style ductless systems are a matched combination of an outdoor condensing unit and an indoor fan coil unit connected only by refrigerant tubing and wires. The fan coil is mounted in the ceiling. This selection of fan coils permits creative solutions to design problems such as: NOTE: Images for illustration purposes only. Actual models may be slightly different. 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. Historical renovations or any application where preserving the look of the original structure is essential. These compact indoor fan coil units take up very little space above the ceiling. Advanced system components incorporate innovative technology to provide reliable cooling performance at low sound levels.
LOW OUND LEVEL When noise is a concern, the ductless 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. 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. AT INTALLATI This compact ductless system is simple to install. A mounting bracket and duct work is needed for the indoor units, and only wire and piping need run between the 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 ducted style ductless systems the equipment of choice, especially in retrofit situations. IMPLE ERVIING AND MAINTENANE 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 the inside using a pressure hose and detergent. On all indoor units, service and maintenance expense is reduced due to easy accessible service panels. In addition, these ducted systems have extensive self diagnostics to assist in troubleshooting. BUILT IN RELIABILITY Ducted style ductless system indoor and outdoor units are designed to provide years of trouble free operation. The ducted indoor 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 ROOM OMORT 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. EOMIAL OPERATI The ducted style ductless system design allows individual or multi 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. EAY TO UE TROL The ducted units have microprocessor based controls to provide the ultimate in comfort and efficiency. The user friendly wired and wireless remote control provides the interface between user and the unit. BUILT IN NATE LIT PUMP actory installed condensate lift pump on the ducted fan coil provides installation flexibility.

APPLIATI DATA UNIT ELETI elect equipment to either match or that can handle slightly less than the anticipated peak load. This provides better humidity control, fewer unit cycles, and less part load operation. or units used in spaces with high sensible loads, base equipment selection on unit sensible load, not on a total anticipated load. Adjust for anticipated room wet bulb temperature to avoid undersizing equipment. UNIT MOUNTING (INDOOR) Refer to unit Installation Instructions for further details. Unit leveling or reliable operation, units should be level in all planes. learance Provide adequate clearance for airflow as shown in ig. 3. Unit location elect a location which provides the best air circulation for the room. These units should be positioned as accessible as possible above the ceiling. The unit return and discharge should not be obstructed by furniture, curtains, or anything which may cause unit short cycling or air recirculation. Duct the unit in the middle of the selected wall (if possible). Duct towards an outside wall, if available, to make piping easier, and place the unit so it faces the normal location of room occupants. UNIT MOUNTING (OUTDOOR) Refer to unit Installation Instructions for further details. Do not install the indoor or outdoor units in a location with special environmental conditions. or those applications, contact your ductless representative. MOUNTING Refer to unit s Installation Instructions for further details. UPPORT Adequate support must be provided to support the weight of all fan coils.

DRAIN NETI Install drains to meet local sanitation codes. The standard ducted fan coil unit condensate lift pump has a maximum lift of 29.5 in. (75mm). WIRING All wires must be sized per NE (National Electrical ode) or E (anadian Electrical ode) and local codes. Use the Electrical Data table MA (minimum circuit amps) and MOP (maximum over current protection) to correctly size the wires and the disconnect fuse or breakers respectively. Per the caution note, only tranded copper conductors with a 6 volt rating and double insulated copper wire must be used. NOTE: The use of BX cable is not recommended. Recommended onnection Method for Power and ommunication Wiring Power and ommunication Wiring: The main power is supplied to the outdoor unit. The field supplied /3 power/communication wiring from the outdoor unit to the indoor unit consists of four () wires and provides the power for the indoor unit. Two wires are high voltage A power, one is communication wiring and the other is a ground wire. Recommended onnection Method for Power and ommunication Wiring (To minimize communication wiring interference) PowerWiring: The main power is supplied to the outdoor unit. The field supplied power wiring from the outdoor unit to the indoor unit consists of three (3) wires and provides the power for the indoor unit. Two wires are high voltage A power and one is a ground wire. To minimize voltage drop, the factory recommended wire size is /2 stranded with a ground. ommunication Wiring: A separate shielded stranded copper conductor only, with a minimum 6 volt rating and double insulated copper wire, must be used as the communication wire from the outdoor unit to the indoor unit. Please use a separate shielded 6GA stranded control wire.! AUTI EQUIPMENT DAMAGE HAZARD ailure to follow this caution may result in equipment damage or improper operation.
