9.1 GENERAL CHECK

• Make sure that the following conditions related to power supply installation are satisfied:
- The power capacity of the electrical installation is large enough to support the power demand of the YUTAKI system (outdoor
unit + DHW tank (if apply)).
- The power supply voltage is within ±10% of the rated voltage.
- The impedance of the power supply line is low enough to avoid any voltage drop of more than 15% of the rated voltage.
• Following the Council Directive 2004/108/EC, relating to electromagnetic compatibility, the table below indicates the Maximum
permitted system impedance Z

N O T E
The data corresponding to DHW tank heater is calculated in combination with the domestic hot water tank accessory "DHWT-(200/300)S-3.0H2E".
• The status of Harmonics for each model, regarding compliance with IEC 61000-3-2 and IEC 61000-3-12, is as follows:
Status regarding compliance with IEC 61000-3-2 and IEC 61000-3-12
Equipment complying with IEC 61000-3-2
(*): Professional use
Equipment complying with IEC 61000-3-12
Installation restrictions may be applied by supply authorities in relation to harmonics
• Check to ensure that existing installation (mains power switches, circuit breakers, wires, connectors and wire terminals) already
complies with the national and local regulations.
• The use of the DHW tank heater is disabled as factory setting. If it is desired to enable the DHW tank heater operation during
normal unit operation, adjust the DSW4 pin 3 of the PCB1 to the ON position and use the adequate protections.
