The 38GVQ/40GVQ inverter driven ductless split 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 inexpensive and creative solutions to design problems such as:
  • Add-on to current space (sun room)
  • 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.
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.

The inverter driven compressor is designed to run at various input power frequencies (Hz) which controls the motor speed of the compressor.
Even Temperature - The control package, including the inverter, monitors outdoor and indoor temperatures as they relate to the selected indoor set point and adjusts the speed of the compressor 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 ability to the inverter system 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 will enhance the humidity control.
Maximum comfort is provided because each space can be controlled individually based on the usage pattern. The air sweep feature provided permits optimal room mixing to eliminate hot and cold spots for the occupant comfort.
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. When sound ordinances and proximity to neighbors demand quiet operation, the 38GVC(Q) 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 high-wall systems 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.
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 38GVC(Q) can be installed close to an outside wall, coils are protected from vandals and severe weather.
This compact ductless split system is simple to install. A mounting bracket is standard with the indoor units and only wires 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 homes or workplace. This makes the 38/40GVC(Q) systems the equipment of choice for retrofit applications.
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, service and maintenance expense is reduced due to easy-to-use cleanable filters. In addition, these high wall systems have extensive self-diagnostics to assist in troubleshooting.
Ductless split 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 will stop and an error code is displayed. For a complete list of abnormal conditions that are detected refer to the Safety and Reliability section in the Standard Features and Accessories. Inverter systems provide additional reliability due to 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.
A condensate pump accessory is available to provide installation flexibility for those applications where gravity cannot be used to dispose of the condensate.
All systems are listed with AHRI (Air conditioning, Heating, and Refrigeration Institute) and are ETL certified per UL 1995 standard.
