INSTALLATION OF INDOOR UNIT

ENGLISH

Point for attention regarding quality of the public electric power supply

This equipment complies with respectively:

- EN/IEC 61000-3-12 (1) provided that the short-circuit power Ssc is greater than or equal to the

minimum Ssc value at the interface point between the user's supply and the public system. It is
the responsibility of the installer or user of the equipment to ensure, by consultation with the
distribution network operator if necessary, that the equipment is connected only to a supply
with respectively: Ssc greater than or equal to the minimum Ssc value.

- European/International Technical Standard setting the limits for voltage changes, voltage

fluctuations and flicker in public low-voltage supply systems for equipment with rated current

≤

75 A.

- European/International Technical Standard setting the limits for harmonic currents produced by

equipment connected to public low-voltage systems with input current 

≤

16 A of > 75 A per

phase.

Circuit Breaker Specification

Perform the electrical wiring work according to
the electrical wiring connection.

- All wiring must comply with local requirements.

- Select a power source that is capable of

supplying the current required by the air
conditioner.

- Use a recognized ELCB(Electric Leakage Circuit

Breaker) between the power source and the
unit. A disconnection device to adequately
disconnect all supply lines must be fitted.

- Model of circuit breaker recommended by

authorized personnel only.
