INDUSTRY LEADING FEATURES / BENEFITS A PERFECT BALANCE BETWEEN BUDGET LIMITS, ENERGY SAVINGS AND COMFORT 

The 37MARA series ductless system is a matched combination of an outdoor condensing unit and an indoor fan coil unit connected only by refrigerant tubing and wires. 
The ductless system permits creative solutions for design problems such as: 
• Add-ons to current space (an office or family room addition) 
• Special space requirements 
• 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. Advanced system components incorporate innovative technology to provide reliable cooling and heating performance at low sound levels. 
Inverter Technology 
The inverter driven compressor is designed to run at various input power frequencies (Hz) which controls the compressor’s motor speed. 
Even Temperature 
The control package, including the inverter, monitors the outdoor and indoor temperatures as they relate to the selected indoor set point and adjusts the compressor speed to match the load and keep the system operating continuously rather than cycling and creating temperature swings. This translates to higher comfort levels for the occupants. 
Rapid 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 quicker. 
Humidity Control – Running the system for longer periods and continuously varying the compressor speed enhances the humidity control. 
Individual Room Comfort
Maximum comfort is provided because each space can be controlled individually based on the usage pattern. 
Low Sound Levels 
When noise is a concern, ductless systems are the answer. When sound ordinances and proximity to neighbors demand quiet operation, the 37MARA unit is the right choice. With the inverter technology, these units run at lower speeds most of the time resulting in reduced sound levels. 
Inverter Technology Enhanced Economical Operation
Ductless systems are inherently economical to operate. Individual rooms are heated or cooled only when required, and since the air is delivered directly to the space, there is no need to use additional energy to move the air in the ductwork. This economical operation is enhanced further when the inverter system output matches the load resulting in a more efficient system. 
Easy-To-Use Controls
The systems have microprocessor-based controls which provide the ultimate in comfort and efficiency. The user friendly wired and wireless remote controls provide the interface between the user and the unit. 
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 or wall openings. In addition, since the 37MARA 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. Only wires and piping 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 37MARA systems the equipment of choice for retrofit applications. 
Simple Servicing and Maintenance
Removing the top panel of the outdoor unit provides immediate access to the control compartment, providing the service technician access to the diagnostic components to facilitate the troubleshooting process. 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 detergent. On the indoor units, service and maintenance expense is reduced due to readily accessible filters. Also, error codes are displayed to alert the user to certain system malfunctions 
Built-in Reliability 
Ductless system indoor and outdoor units are designed to provide years 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 appears. Inverter systems provide additional reliability due to the soft start. This 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 components. 
Agency Listings
All systems are listed with AHRI (Air conditioning, Heating, and Refrigeration Institute) and are CSA certified per UL1995 standard.

45MAHA Series High Wall Air Handlers
The 45MAHA series 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 on the wall, near 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 
• 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 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. 
LOW SOUND LEVELS 
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. 
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 the 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 need to be 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 45MAHAQ 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 the inside using a pressure hose and detergent. On all indoor units, the New Removable Blower assembly and Hood Style cover make maintenance and service less complicated. Additionally, due to Newly Designed, easy-to-use and cleanable filters, service and maintenance expense is reduced. In addition, these high wall 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 high wall 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. Each unit is equipped with a New Humidity Sensor to keep your space comfortable. Year-round comfort can be provided with heat pumps. 
ECONOMICAL OPERATION
 The ductless system design allows individual room heating or cooling when required. Equipped with a New Occupancy Sensor, the system can be set to only operate when the room is being utilized. 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 while air moves through the ducts. 
EASY-TO-USE CONTROLS The high wall units have microprocessor-based controls to provide the ultimate in comfort and efficiency. The user friendly wireless remote control provides the interface between the user and the unit. 
ACCESSORIES Customizing these ductless systems to your application is easily accomplished. Adding a condensate pump accessory to the high wall fan coil provides installation flexibility.
