ELECTRICAL AND CONTROL SETTINGS
6.1 General check
• Make sure that the following condions related to power supply installaon are sased:
✓ The power capacity of the electrical installaon is large enough to support the power
demand of the YUTAKI system (outdoor unit + indoor 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 Direcve 2004/108/EC, relang to electromagnec compability, the
table below indicates the Maximum permied system impedance Z

 NOTE
The data corresponding to DHW tank heater is calculated in combinaon with the domesc 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:

Installaon restricons may be applied by supply authories in relaon to harmonics
• Check to ensure that exisng installaon (main power switches, circuit breakers, wires,
connectors and wire terminals) already complies with the naonal and local regulaons.
• The use of the DHW tank heater is disabled as factory seng. If it is desired to enable the DHW
tank heater operaon during normal indoor unit operaon, adjust the DSW4 pin 3 of the PCB1 to
the ON posion and use the adequate protecons. Refer to the secon “6.2 Electrical connecon”
for the detailed informaon.
