6. After connecting the copper pipes
to the indoor unit, wrap the power

the signal cable with any other wiring.
Wiring
BEFORE PERFORMING ANY ELECTRICAL WORK, READ
THESE REGULATIONS
1. All wiring must comply with local and national electrical codes, regula-
tions and must be installed by a licensed electrician.
2. All electrical connections must be made according to the Electrical Con-
nection Diagram located on the panels of the indoor and outdoor units.
3. If there is a serious safety issue with the power supply, stop work imme-
diately. Explain your reasoning to the client, and refuse to install the unit
until the safety issue is properly resolved.
4. Power voltage should be within 90-110% of rated voltage. Insufficient
power supply can cause malfunction, electrical shock, or fire.
5. If connecting power to fixed wiring, a surge protector and main power
switch should be installed.
6. If connecting power to fixed wiring, a switch or circuit breaker that
disconnects all poles and has a contact separation of at least 1/8in (3mm)
must be incorporated in the fixed wiring. The qualified technician must
use an approved circuit breaker or switch.
7. Only connect the unit to an individual branch circuit outlet. Do not
connect another appliance to that outlet.
8. Make sure to properly ground the air conditioner.
9. Every wire must be firmly connected. Loose wiring can cause the terminal
to overheat, resulting in product malfunction and possible fire.
10. Do not let wires touch or rest against refrigerant tubing, the compressor,
or any moving parts within the unit.
11. If the unit has an auxiliary electric heater, it must be installed at least 1
meter (40in) away from any combustible materials.
7.
Thread this pipeline through the
wall and connect it to the outdoor unit.
8. Insulate all the piping, including
the valves of the outdoor unit.
9. Open the stop valves of the
outdoor unit to start the flow of the
refrigerant between the indoor and
outdoor unit.
CAUTION
Check to make sure there is no
refrigerant leak after completing the
installation work. If there is a refrige-
rant leak, ventilate the area imme-
diately and evacuate the system
(refer to the Air Evacuation section
of this manual).
