LECTRICAL WIRING WORK
All wiring must be performed by an authorized electrician.
All components procured on the site and all electric construction
should comply with the applicable local and national codes.
Be sure to use a dedicated power circuit.
Do not share a common source with other equipment.
Fix cables so that cables do not make contact with the pipes
(especially on high pressure side).
Make sure to connect power supply cables in normal phase. If
connected in reverse phase, the remote controller of indoor unit
indicates "U1" and the equipment cannot operate. Change any
two of the three power supply cables (L1, L2, L3) to correct
phase.
If the contact in the magnetic switch should be forcibly turned on
while the equipment is inoperative, the compressor will burn out.
Never try to forcibly turn on the contact.
Never squeeze bundled cables into a unit.
When cables are routed from the unit, a protection sleeve for the
conduits (PG-insertions) can be inserted at the installation hole.

Point for attention regarding quality of the public electric power
supply
This equipment complies with EN/IEC 61000-3-11
the system impedance Z
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 a system
impedance Z
