3. INSTALLATION 3.1 SPACES FOR INSTALLATION The unit is made grouping all connections to the outdoor hydraulic circuit on a single side. Check that the positioning of the unit allows easy access to that side and the electric control board. Comply with the clearances as shown on the dimensional drawing, and ensure they are calculated allowing easy access to internal components in case of maintenance. - Page 12 – expansion tank and automatic valves to keep the system pressure and compensate for thermal expansion – check that the automatic glycol loading in the circuit is carried out with a mixture of the same concentration as that already present. Otherwise you may risk the hydraulic circuit freezing with serious damage to the parts concerned. –...

GLYCOL UNITS An on-board AQUA Link tank is always included as part of the standard supply of these units. The associated chiller must, in turn, be selected with an on-board tank. This choice is based on the possibility of exploiting a complete system that is not dependent on external accessory elements. -

3.6 CHECKS AQUA Link is not equipped with a completely independent control but is provided with a control module (IQ-nomic) controlled by a signal from the module (IQ-nomic) connected to the Gold and from the (All Year Comfort) module that... -
Page 16: Safety Measures
The connection between different units is created by connecting control modules (IQ-nomic) together as shown in wiring diagrams. The AQUA Link hydraulic module is equipped with inverter technology to adjust the rotation speed of the pumps contained in 4. SAFETY MEASURES The machine complies with Directives 2006/42/EC, 2004/108/EC, 2006/95/EC, 97/23/EC and applicable Technical Standards as specified in the Declaration of Conformity which is an integral part of this manual. -

5. COMMISSIONING 5.1 PRELIMINARY CHECKS – Check that the electric connection has been performed correctly and that all clamps are tightly fastened. – Check that the voltage of line terminals meets specifications. If voltage is subject to frequent changes, contact our technical department to select appropriate protections. -
Page 19: Operation
The two-way valve internal to AQUA Link has the aim to adjust the temperature of the water sent to the circuit of the chilled beams, a value established by the All Year Comfort control. The 0-10 V signal that drives this valve must come from a temperature probe installed on the flow of the secondary circuit (see par. -
