Make sure the installation surface is a flat and vertical noncombustible wall. 70 220 105 170 3.2 Preparing water piping When installing the backup heater in the system, make sure the required minimum water flow rate is guaranteed at all times. For more information, refer to the installation manual of the outdoor unit. 3.3 Preparing electrical wiring 3.3.1 Overview of electrical connections for external and internal actuators. Item Description Wires Interconnection cable Interconnection cable between 1 backup heater kit 5 and outdoor unit Minimum cable section: 0.75 mm2; Maximum running current 0.2A Backup heater Power supply Required number of conductors NBH-9-3 380-415V 3N~ 50Hz 5Wires Minimum cable section: 4 mm2; NOTE More technical specifications of the different connections are indicated on the inside of the backup heater. 03 4 INSTALLATION 4.1 Opening the units 4.1.1 To open the backup heater 2 1 8× 4.2 Mounting the backup heater 4.2.1 To install the backup heater 1 Fix the wall bracket to the wall with M8 screws. Mark the position of the hole at the bottom of the backup heater. Drill a hole for the bottom screw and insert a plug. 2 Fix the wall bracket to the backup heater with M4 screws. 2 1 3× 3 3 Hang the backup heater onto the wall bracket. Make sure it is fixed properly. 4 Fix the bottom of the backup heater to the wall with an M8 expansion screw. 04 4.3 Connecting the water piping 4.3.1 To connect the water piping NOTE Do not use excessive force when connecting the piping. Deformation of the piping can cause malfunction of the unit. Connect the water piping (field supply) to the water inlet and outlet of the backup heater. 3 4 3 Water inlet 4 Water outlet INFORMATION An automatic air purge valve is installed inside the unit. Make sure the air purge valve is not tightened so that the air in the water circuit can be expelled. 4.4 Connecting the electrical wiring The power supply should be an independent circuit with rated voltage. Power supply circuit should be earthed effectively. The wiring must be performed by professional technicians in accordance with national wiring regulations and this circuit diagram. An all-pole disconnection device which has at least 3mm separation distance in all pole and a residual current device (RCD) with the rating of above 10mA shall be incorporated in the fixed wiring according to the national rule. Set the electric leakage protector electric technical standards of the state. The power cord and the signal cord and properly without mutual interference connection pipe or valve After wire connection, check it again correctness before power on. If you want to rotate the electric box, please release the iron tie on the top of the E-box to avoid sensor's connection loosing. 4.4.1 To connect the electrical wiring on the backup heater Routing a High voltage b Low voltage Possible cables (depends on the installed options) Main power supply Backup heater kit connection (to outdoor unit) Backup heater kit sensor (interconnection with outdoor unit) 05 1 Insert the wiring from the bottom of the backup heater. 2 Inside the backup heater, route the wiring as follows: a High voltage wiring b Low voltage wiring ab 3 Fix the wiring with cable ties to the cable tie mountings. 4.4.2 To connect the backup heater power supply Leakage Protection Switch must be installed to the Power Supply of the electric heating. To guarantee the unit is completely earthed, always connect the backup heater power supply and the earth cable. For the power supply, connect 5 wires to XT5/L1+L2+L3+N+ XT5 L1 1 2 3 4 5 6 Power Supply Wires 380-415V 3N~ 50Hz WARNING If a tank with a builtin electrical booster heater is part of the system, use a dedicated power circuit for the backup heater and booster heater. NEVER use a power circuit shared by another appliance. This power circuit must be protected with the required safety devices according to the applicable legislation. 06 4.4.3 To connect the backup heater kit to the outdoor unit For the sensor, connect 2 wires between backup heater terminals XT20/5+6 and control box connector T1. For the connection with the control box, connect 3 wires between backup heater terminals XT20/1+2+3 and control box terminals 14(IBH2) +15(IBH1)+17(C1).
