Evacuation

1.Connect the charge hose end described in the preceding steps to the vacuum pump to evacuate the tubing and indoor unit.

Confirm the "Lo" knob of the manifold valve is open. Then, run the vacuum pump.

The operation time for evacuation varies with tubing length and capacity of the pump. The following table shows the time required for evacuation.

15 min. or more

2.When the desired vacuum is reached, close the "Lo" knob of the manifold valve and stop the vacuum pump.

Finishing the job

1.With a service valve wrench, turn the valve stem of liquid side valve counter-clockwise to fully open the valve.

2.Turn the valve stem of gas side valve counter-clockwise to fully open the valve.

3.Loosen the charge hose connected to the gas side service port slightly to release the pressure, then remove the hose.

4.Replace the flare nut and its bonnet on the gas side ser- vice port and fasten the flare nut securely with an adjustable wrench. This process is very important to pre- vent leakage from the system.

5.Replace the valve caps at both gas and liquid side service valves and fasten them tight.

This completes air purging with a vacuum pump.

The air conditioner is now ready for test running.

This capability offers the convenience of adjusting settings from anywhere, ensuring that your space is always at the desired temperature when you arrive home or the office. The app can provide insights into energy consumption, allowing users to make informed decisions about their heating and cooling usage.

The DMH24DB-1 and DMC24DB-1 models also boast efficient filtration systems that help improve indoor air quality. The filters are designed to capture dust, pollen, and other allergens, contributing to a healthier living or working environment. This is particularly important for individuals with allergies or respiratory issues.

With a variety of cooling and heating modes, these units can cater to different user preferences and seasonal demands. Features like turbo mode are designed to quickly bring a space to the desired temperature, while the eco-friendly refrigerant helps reduce environmental impact.

In summary, the Heat Controller DMH24DB-1 and DMC24DB-1 units are high-performance air conditioning systems equipped with advanced technologies and practical features, making them an excellent choice for anyone seeking efficient and reliable climate control solutions.
