Product catalog summary

Warnings and Recommendations:
It is essential for engineers, installers, users, and service engineers to follow these instructions. Only qualified personnel should install and service the product in accordance with current regulations. Incorrect installation or use of unspecified accessories can cause damage. The boiler must be turned off before any work is performed, and the control panel contains no user-serviceable parts.

Introduction:
The boiler is compatible with most heating and water systems, supporting a maximum pressure of 4 bars and a temperature of 90°C. It includes electronic sequencing control with four-stage modulation and is encased in steel. The heating body is made of mild steel, and the heating elements are stainless steel Incoloy 800.

Specifications:
Five models are available, with power ranging from 57.6 kW to 259.2 kW. The power circuit operates on 400 Volt three-phase, while the control circuit uses 230 Volt single-phase. Internal MCBs and power fuses protect the boiler.

Installation Instructions:
General: Installation must comply with technical standards and regulations. The boiler should not be installed outdoors and requires an expansion vessel.
Hydraulic: The system should maintain a maximum temperature difference of 10°C, operating on a sealed system.
Electrical Supply: Installation must adhere to IEC 364 standards, with external electrical safeties and a recommended differential cut-out device.

Technical Characteristics:
Details include power, nominal supply voltage, heating element type, and dimensions for each model. The maximum working pressure is 4 bars, and the maximum temperature is 90°C.

Commissioning and Maintenance:
Commissioning involves checking water and electrical systems. Regular maintenance is necessary, with spare parts listed at the manual's end.

Specifications:
The document specifies electrical wiring and installation for E-Tech P models, including a table of wire diameters and current capacities, emphasizing adherence to IEE wiring regulations. Adjustments for wire diameter are necessary for higher ambient temperatures based on a derating factor.

Installation Procedures:
Details power variation relative to voltage for different E-Tech P models, providing a comprehensive wiring diagram with color codes. It specifies the procedure for starting the boiler, including switching on the internal MCB, securing panels, and using the ON/OFF switch.

Commissioning:
Involves flushing the system, treating water to prevent corrosion, and pressurizing the boiler to 1.5 bar. Electrical commissioning requires checking all connections, ensuring relays and contactors are secure, and setting the control thermostat.

Maintenance:
Annual servicing by a qualified engineer is recommended. Tasks include visual inspections for leaks and overheating, checking electrical connections, and re-tightening heating element nuts to a torque of 10 Nm. Instructions for replacing heating elements and main fuses are provided.

Power Limitation:
The boiler's maximum power can be limited from 25% to 100% using SW1 and SW2 electrical bridges, with a table indicating the stages activated at each power level.

Spare Parts:
Lists spare parts and their codes for different E-Tech P models, facilitating easy replacement and maintenance.
