Flaring Work, Cutting Tubes, Burrs removal

Installation

FlaringWork

Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the following procedure.

Cutting Tubes

1.Use pipe cutting/flaring kit purchased locally.

2.Measure the distance between the indoor and the outdoor unit.

3.Cut the pipes a little longer than measured distance.

4.Cut the cable 1.5m(59.1in) longer than the pipe length.

Burrs removal

1.Completely remove all burrs from the cut cross section of pipe/tube.

2.Put the end of the copper tube/pipe in a downward direction as you remove burrs in order to avoid dropping burrs into the tubing.

Putting nut on

•Remove flare nuts attached to indoor and outdoor unit, then put them on pipe/tube having completed burr removal.

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. With their durable construction and outstanding performance, they stand out in the competitive astronomy market, offering experiences that inspire awe and curiosity about the universe.
