Installation

Soap water method

1. Remove the caps from the 2-way and 3-way valves.

Liquid side

2. Remove the service-port cap from the 3-way valve.

 

3. To open the 2-way valve turn the valve stem

 

counterclockwise approximately 90°, wait for about

 

2~3 sec, and close it.

Gas side

4. Apply a soap water or a liquid neutral detergent on

2-way valve

the indoor unit connection or outdoor unit

(Open)

connections by a soft brush to check for leakage of

3-way valve

the connecting points of the piping.

(Close)

5. If bubbles come out, the pipes have leakages.

 

Evacuation

 

Hexagonal wrench

Cap

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" and "Hi" knobs of the manifold

 

 

 

 

valve is open. Then, run the vacuum pump.

 

 

 

 

The operation time for evacuation varies with

 

Indoor unit

 

 

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" and "Hi" knobs 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

Manifold valve

 

 

open the valve.

 

 

 

 

 

2. Turn the valve stem of gas side valve counter-

Hi

 

 

clockwise to fully open the valve.

 

 

 

 

 

 

3. Loosen the charge hose connected to the gas

 

 

 

 

side service port slightly to release the pressure,

Close

 

 

then remove the hose.

 

 

 

 

 

 

 

 

4. Replace the flare nut and its bonnet on the gas

 

 

 

 

side service port and fasten the flare nut

 

 

 

 

securely with an adjustable wrench. This

 

 

 

 

process is very important to prevent leakage

 

 

 

 

from the system.

 

 

 

 

 

5. Replace the valve caps at both gas and liquid

Vacuum pump

 

 

side service valves and fasten them tight.

 

 

 

 

 

 

This completes air purging with a vacuum pump.

 

 

 

 

The air conditioner is now ready to test run.

VMH30SB-1, VMC30SB-1 specifications

The Celestron VMC30SB-1 and VMH30SB-1 telescopes are exceptional instruments designed for both amateur astronomers and experienced stargazers alike. These models offer remarkable optical performance in compact packages, making them ideal for both home use and portable observations.

The VMC30SB-1 features a unique catadioptric design combining a primary mirror with a corrector lens, enabling significant improvements in image quality and sharpness. This design minimizes spherical aberration and allows for more precise focusing. With an aperture of 30 cm, it captures ample light for deep-sky observing while maintaining a manageable size for transport.

The telescope utilizes a Vixen-style dovetail mounting, which ensures compatibility with a variety of mounting systems. This flexibility allows users to easily switch between different mounts according to their preference or observing needs. The VMC30SB-1 is also equipped with a 2-inch dual-speed focuser, which provides smooth and precise focusing, enhancing the overall observing experience.

On the other hand, the VMH30SB-1 offers similar optical and mechanical features but integrates a specialized coating technology to enhance light transmission and reduce glare. This ensures that users can enjoy brighter and clearer images of celestial objects, making faint details more visible.

Both models come with a solid, stable optical tube that minimizes vibrations, ensuring steady views even at high magnification. They include a built-in finderscope that simplifies locating celestial objects, coupled with a user-friendly interface for easy operation.

Moreover, Celestron’s innovative StarSense technology is available for these telescopes, allowing for automatic alignment and facilitating a smooth observing experience. Users can set up quickly, even in challenging conditions, without the need for extensive setup procedures.

In conclusion, the Celestron VMC30SB-1 and VMH30SB-1 are robust telescopes that bring a blend of advanced technology, superior optics, and user-friendly features. Whether for detailed planetary observation or exploring deep-sky wonders, these telescopes are a remarkable choice for enthusiasts looking for quality and convenience in one reliable package.
