FEATURES / BENEFITS
A PERFECT BALANCE BETWEEN BUDGET LIMITS, ENERGY SAVINGS AND COMFORT.
The 40MB*D 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:

• Add-ons to current space (an office or family room addition)
• Special 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 SOUND LEVELS
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.
SECURE 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 outdoor units can be installed close to an outside wall, coils are protected from vandals and severe weather.
FAST INSTALLATION
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.
SIMPLE SERVICING 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-thru design of the outdoor section means that dirt accumulates on the outside surface of the coil. Coils 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
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 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 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.
EASY-TO-USE CONTROLS
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 CONDENSATE LIFT PUMP
Factory installed condensate lift pump on the ducted fan coil provides installation flexibility.
