WARNINGS

These instructions must be read and understood before installing and maintaining the device.
IMPORTANT! FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN A SAFETY HAZARD!

1 The  device  must  be  installed,  commissioned  and  maintained  by  qualified  technical  personnel  in  accordance with  national  regulations  and/or  relevant  local

requirements. 

2 If the device is not installed, pre-run checked and maintained correctly in accordance with the instructions provided in this manual, it may not work properly and

may endanger the user.

3 Clean the pipes of any particles, rust, incrustations, limescale, welding slag and any other contaminants. The hydraulic circuit must be clean. 

4 Make sure that all connection fittings are watertight.

5 When connecting water pipes, make sure that threaded connections are not mechanically overstressed. Over time this could result in breakage, with water leaks

causing damage and/or injury.

6 Water temperatures higher than 50°C may cause severe burns. When installing, commissioning and maintaining the device, take the necessary precautions so

that these temperatures will not be hazardous for people.

7 In the case of particularly hard or impure water, the device must be fitted for filtering and treating the water before it enters the device, in accordance with current

legislation. Otherwise the device may be damaged and will not work properly.

8 Any use of the device other than its intended use is prohibited.

9 Any combination of the device with other system components must be made taking the operational characteristics of both units into consideration. 10 An incorrect

coupling could compromise operation of the device and/or system.

IMPORTANT

: Risk of electric shock. Live parts. Shut off the electric supply before opening the device box.

1 During installation and maintenance operations, always avoid direct contact with live or potentially hazardous parts.

2 The device must not be exposed to water drops or humidity, direct sunlight, the elements, heat sources or high intensity electromagnetic fields. This device cannot

be used in areas at risk of explosion or fire.

3 The device must be connected to an independent bipolar switch. If work has to be done on the device, cut off the electric supply first. Do not use devices with

automatic or time reset, or which may be reset accidentally.

4 Use suitable automatic protection devices in accordance with the electrical characteristics of the region where the device is installed and in compliance with current

legislation.

5 The device must always be earthed before it is connected to the electric supply. If the device has to be removed, always disconnect the earth connection after

disconnecting the electric supply conductors. Check that the earth connection has been made to the highest of standards under applicable legislation.

6 Electrical installation must only be carried out by a qualified technician, in accordance with legal requirements.

7 The device does not contain asbestos or mercury.

8 The device is not designed for use by persons of reduced mental, physical or sensory capacity (including children) or persons lacking experience, unless they are

supervised or instructed in use of the device by a person responsible for their personal safety.

LEAVE THIS MANUAL AS A REFERENCE GUIDE FOR THE USER. DISPOSE OF THE PRODUCT IN COMPLIANCE WITH CURRENT LEGISLATION
THE MANUFACTURER RESERVES THE RIGHT TO CEASE PRODUCTION AT ANY TIME AND TO MAKE ANY CHANGES DEEMED USEFUL OR
NECESSARY WITHOUT THE OBLIGATION OF PRIOR NOTICE.

SAFETY INSTRUCTIONS

NOTES

:

1 Install water hammer arresters to compensate for any overpressure in the domestic water circuit;

2 In the presence of hot water recirculation or if non-return valves are fitted on the domestic cold water inlet, provision must be made to accommodate expansion of

the water contained in the system and in the heat interface unit;

3 All hydraulic connections must be checked before pressurising the system. Vibration during transport may cause the connections to become loose. DO NOT APPLY

EXCESSIVE TIGHTENING TORQUE otherwise the components may be damaged.
