Pump Instructions

Technical data for the SUNTEC AS pump includes viscosity and pressure ranges, voltage, and temperature limits.

Technical Specifications
The SUNTEC AS47C oil pump specifications include a built-in solenoid valve for fast cut-off and cut-on functions. It operates with light oil, B10 heating oil/biofuel blend, and kerosene, suitable for one or two-pipe systems. The viscosity range is 1-12 mm²/s, pressure range is 10-15 bar, and the rated voltage is 220/240V 50/60 Hz. The maximum oil temperature is 60°C.

Operating Principle
The pump draws oil from the tank through a built-in filter, regulating pressure to the nozzle line. In a two-pipe system, excess oil returns to the tank, while in a one-pipe system, it returns to the suction port. The solenoid valve is normally open, closing upon activation to build pressure rapidly for a sharp cut-on function. Cut-off occurs when the burner stops, draining oil to the return and closing the nozzle valve immediately.

Installation and Maintenance Procedures
Instructions are provided for replacing the pump filter, solenoid valve, and gasket seal. Key steps include disconnecting power, removing components, installing new parts, and checking functionality. Safety precautions emphasize ensuring components are without power during maintenance.

Suction Line Tables
The tables provide calculated values for pipe dimensions and oil velocity to prevent turbulence, which can cause pressure losses and noise. They apply to standard fuel oil and specify maximum permissible pressure at the suction and pressure sides as 2.0 bar.

Electrical Components and Safety Systems
The document details the wiring diagram and component list for the LMV burner control system, including safety systems like door switches and pressure limiters. It emphasizes separate cabling for safety signals and provides instructions for replacing electrical components.

Troubleshooting
Common issues such as the burner not starting, delayed ignition, and noise in the pump are addressed with potential causes and remedies. Solutions include adjusting settings, checking components, and ensuring oil parameters match the burner's design.
