INSTALLATION 9.1 SAFETY CONSIDERATIONS A series of recommendations to follow for correct installation of the unit are included below. The installation, repair and maintenance of these units must be performed with caution because of the presence of electrical and electronic components and because of the pressure system of the refrigerant circuit. Only trained and qualiﬁed personnel should perform installation, adjustment and maintenance operations on the unit. The manufacturer declines all liability in the event of negligence or the failure to follow the safety rules described below: - Work under completely safe conditions, free from obstacles and in a clean environment. - Respect legislation in force. - Before starting up the unit, conﬁrm that both the unit and its components are in perfect condition. - Use safety goggles and gloves when working. Use a ﬁreproof blanket during welding operations. - Position units on ﬁrm ground that supports the load weight and that allows maintenance to subsequently be performed correctly on the same. - Use the speciﬁed cables, and make the correct connection to terminals. - Provide an independent power supply connection for the unit. - Verify that the supply voltage corresponds to the voltage on the speciﬁcations plate. - Make the corresponding earth connection. - Safely perform the installation work of the hydraulic and drainage lines according to the instructions in this manual and according to legislation in force. - When the unit is operating, some parts of the refrigerant circuit (compressor and discharge line) can reach temperatures exceeding 70º C. Be especially careful when accessing the interior of the unit. - The unit can work in "normal" environments of residential, commercial or light-industry installations. The unit cannot be installed in an explosive atmosphere or an atmosphere that is aggressive to the unit's components. For special applications, the manufacturer must be consulted. Very important! Before beginning any installation or repair operations on the unit, turn off the main electric power supply switch. An electric shock can cause personal injury. 18 9. INSTALLATION 9.2 LOCATION OF THE UNITS Inspect the units when they are received to verify that no damage has occurred during transport. If a unit is damaged, a claim must be submitted immediately to the company that made the delivery. Location of the Indoor Unit The indoor unit is designed to be installed inside a home. Therefore, the indoor unit has the same measurements at the base as those of a common electrical appliance. The height can also be adjusted using small, adjustable legs. When the indoor unit is installed, the area around the access door must be left free. The spaces described in section 7 (Service Space) must also be left free. Location of the Outdoor Unit The outdoor unit must be installed with an orientation that is suited to the weather characteristics of the region where it is installed. In case of doubt, consult the manufacturer. It must be installed so that air circulates freely, thereby preventing the effects of re-circulations, which can reduce the unit's performance. When the outdoor unit is installed, the area around the front of the unit must be left free. The spaces described in section 7 (Service Space) must also be left free. 19 9. INSTALLATION 9.3 HYDRAULIC CONNECTIONS All the hydraulic connections are identiﬁed, as it can be seen in Figures 1 and 2: Figure 1 DHW outlet Network water inlet Figure 2 Climate water inlet Climate water outlet The unit is equipped with ﬂexible hoses to facilitate the hydraulic connections of the air conditioning circuit (Figure 3). Figure 3 20 9. INSTALLATION The common intake must be led from the safety valves of the two tanks to the drain (Figure 4). Figure 4 Outlet to drain Air Conditioning Hydraulic Circuit - Water pump The operation of the closed air conditioning circuit means that water carries the heating or cooling energy from the Triaqua unit to the secondary unit of the installation. This forced circulation is performed by the water pump. This water pump must be installed by the installer and must be calculated to meet the required water ﬂow rate and to be able to overcome the head loss (installation + machine). See section 8. For its electrical condition, see section 9.4 (Electrical Connections). IMPORTANT: A pump that is too small could cause inadequate operation or even irreparable damage. - Water Flow switch It is essential to ensure that there is a minimum ﬂow of water in the air conditioning circuit. It is therefore necessary to install a ﬂow switch to protect the machine. The indoor unit comes prepared for the electrical condition of the ﬂow switch (WT-WT connections) (terminals 17 and 18). Figure 5 The bridge between those terminals must be removed, and the ﬂow switch must be connected to them. IMPORTANT: Insufﬁcient water could cause irreparable damage to the unit. 21 9. INSTALLATION - Differential pressure valve In order to ensure that water always returns to the unit on the air conditioning circuit, a differential pressure valve must be installed. The differential pressure switch guarantees the required minimum ﬂow rate for proper operation of the heat pump when the thermostatic valves close, and it limits the differential pressure of the installation. IMPORTANT: If water does not return to the unit, it could cause irreparable damage to the unit. Filling the hydraulic circuits and checking pressures Very important! In order to ﬁll the hydraulic circuits, proceed in the order indicated below. 1. Filling the DHW secondary circuit. (DHW plate exchanger - DHW tank). Filter built inside of pressure reducer 3 2 1 4 Figure 6 1. 2. 3. 4. 5. Network water inlet valve Pressure reducer Pressure gauge Pressure reducer shut-off valve Air conditioning circuit ﬁll valve 5 - Open the water inlet valve of the unit's network (see Figure 6) - Open the air bleed of the DHW tank (Figure 7). Close this air bleed when air stops coming out and water does. - Open any DHW consumption point to bleed air from the installation. - The indoor unit incorporates a pressure regulator valve (factory-rated to 2.5 bar). If necessary, adjust the water inlet pressure to the unit (normally 2.5-3 bar). - Check that the DHW pump rotates in the correct direction by accessing the shaft of the same through the maintenance screw. Figure 7 22 9. INSTALLATION 2. Filling of the air conditioning circuit (air conditioning plate exchanger - air conditioning buffer tank). - Be sure that the circuit to be climatised (radiating ﬂoor, fan-coil, etc.) has previously been ﬁlled and bled. - Keep all water inlet and outlet shut-off valves closed (Figure 9). - With the water inlet valve of the unit's network open (1), Figure 6, open the manual ﬁll valve of the air conditioning circuit (Figure 8). - Open the manual bleed located at the top of the air conditioning tank, and keep it open until all the air has been eliminated from the circuit (Figure 10). Figure 8 Inlet shut-off valve Figure 9 Outlet shut-off valve Figure 10 - Check the two D.H.W. water pumps are turning correctly by checking its axis working by openning the maintenance screw in the middle of the water pump. Rotate the maintenance screw for several times with a screw driver. maintenance screw Figure 5.4 23 9. INSTALLATION - Once the air has been bled from the unit, close the air conditioning ﬁll valve (Figure 8), and use the pressure gauge installed on the unit's control panel to check that the pressure of said circuit is around 1.5 bar. 3. Filling of the primary DHW circuit (DHW plate exchanger - air conditioning plate exchanger) - Open the air bleed of the primary DHW circuit (Figure 11). - Connect the electric power supply to the indoor unit, WITHOUT TURNING THE UNIT ON, and select the DHW operation. - The 3-way water valve of the air conditioning circuit activates and begins to ﬁll said primary DHW circuit (hydraulic circuit between the plate exchangers). - When water comes out through the air bleed of this primary DHW circuit, close the air bleed and disconnect the electric power supply to the indoor unit. - If it were necessary, ﬁll the air conditioning hydraulic circuit with water. Open the ﬁll valve of said circuit (Figure 8). Keep the pressure around 1.5 bar. - Open the shut-off valves (inlet and outlet) of the air conditioning circuit (Figure 9) - Use the pressure gauge installed on the control panel of the indoor unit to check the pressure of the air conditioning hydraulic circuit (normal is 1.5 bar). - Be sure that the entire installation of the circuit to be air conditioned has water pressure and is completely bled of air. The existence of air in the air conditioning circuit could cause irreparable damage to the unit. It is essential to adequately bleed the air conditioning circuit of the installation. To do so, air bleeds will have been installed at the highest part of the home's circuit in order to suitably eliminate all air in the installation. - It is advisable to connect the air conditioning pump directly to the network - meaning only the water pump of the air conditioning circuit - for a period of time in order to eliminate any air in said circuit. Attention! Do not turn on the unit to operate the water pump. If the unit is turned on while the pump is running to bleed air from the air conditioning water circuit, irreparable damage could be caused to the unit. 24 9. INSTALLATION Water ﬁlter (air conditioning circuit) - The unit has a mesh ﬁlter (Figure 12) on the air conditioning (return) circuit, and its mission is to retain particles or dirt that could remain in the home's air conditioning circuit. Figure 12 Attention! Dirt in the installation could cause irreparable damage to the unit. - After making all the connections and after ﬁlling the circuit, and before turning the unit on, it is advisable to turn on the pump of the air conditioning circuit for a period of time in order to retain any particles and impurities that could be in the installation. To do soy, the air conditioning pump has to be connected directly to the network. - Once this operation has been performed, and with the pump stopped, the inlet and outlet shut-off valves of the air conditioning circuit (Figure 9) must be closed, the water must be drained from the air conditioning tank through its drain, and the ﬁlter's mesh must be cleaned. Afterwards, the circuit will be ﬁlled again. - In order to be sure that there is no dirt in the circuit, it is advisable to perform this operation as many times as necessary. - After having checked that the air conditioning circuit is clean, ﬁll it with glycol to approximately 20% of the total volume of the installation. - It is advisable to make periodic checks, which includes cleaning the ﬁlter's mesh, in order to be sure that there is no dirt in the circuit. Water treatment It is advisable to install a ﬁltering system (water softener, etc.) to prevent the build-up of lime and other minerals from the water on the pipes or on some components of the unit. This will prevent damage to both the installation and the unit itself. Likewise, it is advisable to perform periodic maintenance on the installation and unit. 25 9. INSTALLATION 9.4 ELECTRICAL CONNECTIONS Before starting any work on the electrical installation, be sure that the main power switch is disconnected. General recommendations - The installer must protect the unit's electric power supply line using automatic disconnection devices, a circuit breaker and a residual-current device that are suitable for the installation and in accordance with legislation in force. - The electric power supply to the unit has to be within a certain voltage range (see the table of electric consumption in section 4). - Special care must be taken when connecting the earth cable. The earth cable should be somewhat longer than that of the phase cable. Preliminary operations On the outdoor unit: - Remove the access panel to the electrical panel located on the front right of the unit. - Check that the characteristics of the network match the data indicated on the unit's serial plate. - Make the electric power supply connection and interconnection between the outdoor and indoor units through the 2 cable seals located on the side of the unit. Figure 13 Electric Power Supply Interconnection signal wires - Be sure that the cross section of the electric power supply cables is suitable for the total consumption of the unit. See the table below. On the indoor unit: - Open the front panel by turning the unit's latch. - Unbolt the control panel from the structure of the unit, and slide it out along the support guides so that you have access to the unit's connection terminal board (Figure 14). 26 9. INSTALLATION Figure 9 Figure 11 Figure 10 Power supply (connection and interconnection between units) Before commissioning of the unit must perform the following connections: - Mains supply (outdoor unit), Figure 8. - Interconnection between the outer and inner drive, figures 8, 10 and 11. - Connect the air conditioning water pump, Figure 10.

PROTECTION AGAINST INDIRECT CONTACTS. The installer must protect the unit's electric power supply line using automatic disconnection devices, a circuit breaker and a residual-current device that are suitable for the installation and in accordance with legislation in force. Because the unit incorporates an electric heater, it must be kept in mind when sizing the power supply line of the indoor unit. The unit's power supply cables cannot be lighter than ordinary, ﬂexible polychloroprene sheathed cable (H05 RN-F designation). Starting up the unit using an incorrect voltage line is not covered by the TriAqua warranty. Pay special attention to connecting the earth protection cable. It should be the ﬁrst cable connected, and its length must be greater than that of the live cables. 28 9. INSTALLATION 9.5 REFRIGERANT CONNECTIONS General considerations The refrigerant lines will be interconnected as follows: - The indoor unit has the gas and liquid intakes identiﬁed with stickers as follows: Gas line: Gas (refrigerante)/Gas (refrigerant) Liquid line: Líquido (refrigerante)/Liquid (refrigerant) - All the refrigerant connections, just like the water connections, are threaded. - The lines have to be insulated to prevent condensation and thermal losses. - Once the lines have been installed, apply a vacuum to the refrigerant circuit of the indoor unit until a pressure of -1 Kg/cm2 is reached for at least 2 hours. - The refrigerant circuit can be emptied and the refrigerant can be charged through the service valves located on the right side of the outdoor unit. - Check that there are no leaks on the refrigerant circuit. Connection between units On the indoor unit: The indoor unit is equipped with couplings for screwing on the connections. Take the lines to the outlet zone of the connections on the indoor unit (see the schematic in section 6. Dimensions), and make the connections there. The indoor unit leaves the factory with a dry nitrogen charge. The refrigerant lines of the indoor units are factory-ﬁtted with adapters and nuts to guarantee a perfect seal until use.
