Outdoor Unit Installation 17
5.1.3.
To reduce vibrations of wall-mounted unit
You can install the wall-mounted unit with rubber gaskets to reduce
vibrations and noise.
Step 4: Connect communication and power cables
The outside unit's terminal block is protected by an electrical wiring cover
on the side of the unit. A comprehensive wiring diagram is printed on the
inside of the wiring cover.
WARNING
BEFORE PERFORMING ELECTRICAL WORK, READ THESE
REGULATIONS:
1
All wiring must comply with local and national electrical standards,
and must be installed by a licensed electrician.
2
All electrical connections must be made according to the Electrical
Connection Diagram located on the side panels of the indoor and
outdoor units.
3
If there is a serious safety issue with the power supply, stop work
immediately. Until the safety issue is properly resolved.
4
Power voltage should be within 90-100% of rated voltage.
Insufficient power supply can cause electrical shock or fire.
5
If connecting power to fixed wiring, install a RCD protector and main
power switch with a capacity of 1.5 times the maximum current of
the unit.
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.
WARNING
BEFORE PERFORMING ANY ELECTRICAL OR WIRING WORK, TURN OFF
THE MAIN POWER TO THE SYSTEM.

a)
Using wire strippers, strip the rubber sleeve from both ends
of cable to reveal about 40mm (1.57in) of the wires inside.
b)
Strip the insulation from the ends of the wires.
c)
Using a wire crimper, crimp u-lugs on the ends of the wires.
Pay attention to live wire
While crimping wires, make sure you clearly distinguish the Live ("L")
Wire from other wires.
WARNING
ALL WIRING MUST PERFORMED STRICTLY IN ACCORDANCE WITH THE
WIRING DIRGRAM LOCATED INSIDE THE OUTDOOR UNIT SWIRE COVER.
2
Unscrew the electrical wiring cover and remove it.
3
Unscrew the cable clamp below the terminal block and place it to
the side.
4
Match the wire colors/labels with the labels on the terminal block,
and firmly screw the u-lug of each wire to its corresponding terminal.
5
After checking to make sure every connection is secure, loop the
wires around to prevent rain water from flowing into the terminal.
6
Using the cable clamp, fasten the cable to the unit. Screw the cable
clamp down tightly.
7
Insulate unused wires with PVC electrical tape. Arrange them so that
they do not touch any electrical or metal parts.
8
Replace the wire cover on the side of the unit, and screw it in place.
