Operating Conditions:

When cooling is needed year round, including when outdoor temperatures are apt to fall below freezing, our V Series inverter driven ductless mini-split systems will continue to work, as they come with factory installed low ambient controls. The low ambient feature works by regulating the head pressure by varying the amount of air flow through the condenser, which helps to prevent evaporator freeze ups and low pressure problems due to low ambient outdoor temperatures. Low ambient operation is a great feature for temperature/humidity sensitive environments or applications such as server/computer rooms, supermarkets, restaurants, or cooling tower fans. Additionally, a crank case heater is required and factory installed, as it is needed for use with the low ambient controls. The crank case heater minimizes liquid refrigerant migration to the compressor when the compressor is not operating and helps to keep the compressor oil warm enough so that it remains fluid to prevent slugging. Crank case heaters also assist to greatly reduce heat loss to ambient air. Together, the lower ambient feature combined with the factory installed crank case heater, will not only allow the air conditioner to cool year round, but will also prevent compressor failure in low ambient conditions.

Manual Operation:

Manual operation can be used temporarily to run the unit without using the remote controller. This feature can also be used to test the unit during installation and troubleshooting by an authorized service technician.

NOTE: The unit must be turned off before operating the manual control button. If the unit operational, continue press- ing the manual control button until the unit is off.

1.Grasp both sides of the panel and pull it down. The panel opens upward to an angle of 15°. Push the panel upward and then lift it up.

2.One press of the manual control button will lead to the forced AUTO operation. If the button is pressed twice within five seconds, the unit will operate under forced COOL operation. Press the button a third time to stop the manual operation.

3.Close the panel firmly to its original position.

CAUTION:

This button is used for testing purposes only.

To restore the remote controller to control the unit, siply

begin to operate the unit with the remote controller.

One of the key highlights of the VMH series is its advanced inverter technology, which allows the units to adjust their compressor speed according to the heating or cooling demands of the environment. This feature ensures optimal energy consumption, significantly reducing utility bills compared to conventional systems that operate at a fixed speed. The inverter technology also results in quieter operation, enhancing comfort whether in a home or office setting.

The VMH models come equipped with high SEER (Seasonal Energy Efficiency Ratio) ratings, which mark them as some of the most energy-efficient options available. This efficiency is not just eco-friendly; it also means that users can expect long-term savings. In addition, the units feature R-410A refrigerant, known for its low environmental impact and effectiveness in providing superior cooling and heating performance.

Ease of use is another hallmark of the VMH series. Each model is designed with a smart control panel, allowing users to easily adjust settings, set timers, and monitor energy usage. Some models also offer compatibility with smart home systems, enabling control via smartphones or tablets for optimal convenience.

Durability is a critical characteristic of the Maytag VMH series. Engineered with robust materials and a corrosion-resistant finish, these units can withstand diverse weather conditions, making them ideal for various climates. The self-diagnostic tool integrated into the units ensures that maintenance and troubleshooting processes are simplified, promoting longevity and reliability.

In terms of installation, the VMH models are versatile. They can be mounted in various configurations to suit different spaces, whether it be wall, ceiling, or floor-mounted installations. This adaptability, combined with a sleek design, allows these units to blend seamlessly into any interior aesthetic.

Overall, the Maytag VMH 09, 12, 18, and 24 models stand out in the market for their combination of cutting-edge technology, energy efficiency, and user-centric features, making them an excellent choice for individuals and businesses seeking reliable heating and cooling systems.
