7.6.Impeller blockage.

8.When stopped, unit turns slowly in the reverse direc- tion:

8.1.Leaks on air locks in suction pipe.

8.2.Partial blockage in check valve.

9.In pressure boosting applications, the unit starts and stops too often:

9.1.Pressure switch settings are incorrect.

9.2.Tank size may be incorrect.

10.In pressure boosting applications, the unit does not stop:

10.1.Pressure switch maximum setting is higher than was specified.

10.2.Direction of rotation incorrect. See Rotation.

SSH-C, SSH-F specifications

ITT SSH-C and SSH-F are remarkable advancements in the field of telecommunications, specifically designed to enhance the efficiency and effectiveness of digital signaling systems. Both models are produced by ITT, a renowned leader in technological innovations and solutions for various sectors including defense, communications, and transportation.

The SSH-C model stands out for its ability to provide a high level of reliability and performance in digital communication. One of its main features is its versatility; it is tailored for different types of applications ranging from military communications to commercial networks. The device employs advanced encoding and modulation techniques, ensuring that data transmission remains robust even in challenging environments. This characteristic is crucial for maintaining the integrity of the signal in situations where interference is prevalent.

On the other hand, the SSH-F model emphasizes flexibility and scalability. It is designed to accommodate a wide range of communication protocols, making it suitable for modern networks that may employ diverse technologies. Its adaptability is a significant advantage, allowing organizations to upgrade their systems without a complete overhaul. The SSH-F also features an intuitive user interface, simplifying the configuration and management of network operations.

Both SSH-C and SSH-F utilize cutting-edge technologies including digital signal processing (DSP) and error correction algorithms, which significantly enhance data throughput and minimize latency. This is particularly beneficial in applications requiring real-time data transmission, such as voice over Internet Protocol (VoIP) services and video conferencing.

Furthermore, ITT has incorporated security features in both models to protect against various threats. With the rise of cyberattacks, having robust security protocols is no longer optional but a necessity. Features such as encryption ensure that data remains confidential and tamper-proof, safeguarding sensitive information in transit.

Another notable characteristic of both models is their compact design, which allows for easy integration into existing systems without demanding extensive infrastructure changes. This makes them ideal for organizations looking to upgrade while maintaining cost-efficiency.

In summary, ITT SSH-C and SSH-F models represent significant progress in digital signaling technology, showcasing impressive features such as versatility, flexibility, advanced encoding techniques, and robust security.
