Nominal 3 Ton, R454B, Single Zone DFS Heat Pump Condenser, 208/1

The 37MBHAQ 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 toprovide reliable cooling and heating performance at low sound levels.

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.

Maximum comfort is provided because each space can be controlled individually based on the usage pattern.

When noise is a concern, ductless systems are the answer. When sound ordinances and proximity to neighbors demand quiet operation, the 37MBHAQ unit is the right choice. With the inverter technology, these units run at lower speeds most of the time resulting in reduced sound levels.

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.

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.

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 37MBHAQ can be installed close to an outside wall, coils are protected from vandals and severe weather.

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 37MBHAQ systems the equipment of choice for retrofit applications.

The larger open area of the service port provides more space for installers to handle the wires and line set, providing the service technician access to the diagnostic components to facilitate the troubleshooting process. In addition, the draw-through 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

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.

All systems are listed with AHRI (Air conditioning, Heating, and Refrigeration Institute) and are CSA C22.2 No. 60335-2-40 certified per UL 60335-2-40 standard.
