Electric wiring and the application

WARNING
• Switch off the main power switch of the indoor
and outdoor machine for more than 1 minutes
before the wiring or regular inspection.
• To prevent the destruction of wires and
electrical components by rats or other animals.
Serious, it may lead to the occurrence of fire.
• To avoid damage to the wire, avoid contact with
refrigerant pipes, steel edges and electrical
components. Serious, it may lead to the
occurrence of fire.
CAUTION
• Secure the power cord with a wire tie in the
machine.
Note:
when the wiring of the outdoor machine is not
using the wire, it should be fixed with the rubber
ring.
CAUTION
• In the case of 3 phase 5 wire type, the
power supply of the indoor machine must be
connected use L1 line and N line, prohibit the
use of L1-L2, L1-L3, Otherwise the electrical
part will be damaged.
