3 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 Data38 MARBO utdoor Unit Single Zone ductless SystemSizes 09 to 362 Specifications subject to change without notice. 38 MARB-01 PDInverter TechnologyThe inverter driven compressor is designed to run at various inputpower frequencies (Hz) which controls the compressor s motor Temperature The control package, including the inverter,monitors the outdoor and indoor temperatures as they relate to theselected indoor set point and adjusts the compressor speed to matchthe load and keep the system operating continuously rather thancycling and creating temperature swings.

4 This translates to highercomfort levels for the Pull Down/Warm-Up Comfort is increased by the inverter system s ability to ramp up the compressor speed enabling the system to reach the user selected room temperature set point Control Running the system for longer periods andcontinuously varying the compressor speed enhances the Room ComfortMaximum comfort is provided because each space can be controlled individually based on the usage Sound LevelsWhen noise is a concern, 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 the sound ordinances and proximity to neighbors demand quiet operation, the 38 MARB unit is the right choice.

5 With the inverter technology, these units run at lower speeds most of the time resulting in reduced sound Technology Enhanced Economical OperationDuctless systems are inherently economical to operate. Individual rooms are heated or cooled only when required, and since the air isdelivered directly to the space, there is no need to use additionalenergy to move the air in the ductwork. This economical operationis enhanced further when the inverter system output matches the load resulting in a more efficient ControlsThe systems have microprocessor-based controls to provide the ultimate in comfort and efficiency. The user friendly wired and wireless remote controls provide the interface between the user and the OperationIf security is an issue, outdoor and indoor units are connected onlyby refrigerant piping and wiring to prevent intruders from crawlingthrough ductwork or wall openings.

6 In addition, since the 38 MARB can be installed close to an outside wall, coils are protected from vandals and severe InstallationThis compact ductless system is simple to install. Only wires andpiping need to run between the indoor and outdoor units. These units are fast and easy to install ensuring minimal disruption to customers in homes or the workplace. This makes the 38 MARB systems the equipment of choice for retrofit Servicing and MaintenanceRemoving the top panel of the outdoor unit provides immediateaccess to the control compartment, providing the service technicianaccess to the diagnostic LEDs to facilitate the troubleshootingprocess. In addition, the draw-thru design of the outdoor unit means that dirt accumulates on the outside surface of the coil. Coils can be cleaned quickly from the inside using a pressure hose and the indoor units, service and maintenance expense is reduceddue to the permanent easy to clean filters.

7 Also, error codes are displayed on the front panel to alert the user to certain ReliabilityDuctless system indoor and outdoor units are designed to provideyears of trouble-free operation. Both the indoor and outdoor units are well protected. Whenever the microprocessor detects abnormal conditions, the unit stops and an error code systems provide additional reliability due to the soft refers to the ability of the inverter to start the compressor motor using reduced voltage and reduced current. This feature is beneficial from an electrical standpoint (eliminates current spikes) as well as an overall reliability standpoint due to reduced stress on all associated system ListingsAll systems are listed with AHRI (Air conditioning, Heating, andRefrigeration Institute) and are ETL certified per UL Specifications subject to change without notice.
