BERETTA SC ACS 160 E - 225 E LOW ENERGY

The SC ACS 160 E - 225 E is a modern domestic hot water mixer that can use the heat accumulated in a storage cylin-

der to produce high volumes of domestic hot water. The unit incorporates an AISI 316 stainless steel brazed plate heat

exchanger.

The unit is controlled by an electric panel complete with a controller for the control and management of the functions of

all system components. The unit also permits the manual operation of all system components.

The heat exchanger’s PRIMARY CIRCUIT comprises:

- A 3-way mixer valve for stabilising the temperature of incoming hot water

- 2 modulating pumps with 0-10 V control, installed in parallel

- A warning system with buzzer and LED indicator to warn of malfunctions in either of the 2 pumps

- A return line diverter valve that controls two separate storage cylinders or one storage cylinder with stratiﬁcation control.

The heat exchanger’s SECONDARY CIRCUIT, which delivers the domestic hot water comprises:

- An electronic meter for DHW temperature and ﬂow control.

- A variable speed circulation pump.

Disconnect the product from the mains power supply before commencing any work on it.

The product must be installed in conformity to the laws and standards applicable in the country of installation.

The manufacturer’s responsibility ends with the supply of the product. The product must be installed in accordance with

industry standards and with these instructions, adopting best professional practices, by suitably qualiﬁed persons wor-

king for a company that will assume full responsibility for the completed installation

The manufacturer cannot be held responsible for consequences deriving from the unauthorised modiﬁcation of the pro-

duct or from the use of non-original spare parts.

b Do not expose the product to the elements. It is not designed for use outdoors

ELECTRICAL CONNECTIONS

The product must be installed and all electrical connections made by suitably qualiﬁed personnel in conformity to appli-

cable standards.

The product’s mains power cable must be connected to a fused, two-pole switch (power supply 230 VAC, 50 Hz). The

product must be correctly connected to ground.

b The product must be connected to the mains power supply via an earth leakage breaker in accordance with ap-

plicable standards. Correct functioning is only guaranteed provided the product is used with a pump for which it is

designed. The manufacturer cannot be held responsible for the consequences of improper uses.

WATER CONNECTIONS

On completion of all transport or handling operations, always check the tightness of the water ﬁtting ring nuts.

Take particular care when connecting the product to the water supply. When tightening a ﬁtting, always hold the opposite

ﬁtting steady with a second tool to avoid twisting the copper pipes.

b The product must be installed, connected and tested by suitably qualiﬁed persons, in conformity to applicable

standards and in accordance with the instructions provided in the documentation supplied with it. N.B. All pipes

must be insulated in conformity to applicable standards.

It is essential to respect the following precautions when using the product:

- Do not touch hot parts of the product such as the water inlet and outlet pipes. Contact with hot parts can cause painful

burns.

- Do not splash water or any other liquid over the product.

- Do not rest any objects on top of the product.

- Do not expose the product to steam from a cooking hob.

- Do not allow children or inexperienced persons to operate the product.

- Do not touch the product when barefoot or wet.

- Do not pull on the electrical cables.
