Indoor Unit Installation
INCORRECT
Kinks in the drain hose
will create water traps.

INCORRECT
Do not place the end
of the drain hose in
water or in containers
that collect water. This
will prevent proper
drainage.

BEFORE PERFORMING ELECTRICAL WORK, READ THESE
GUIDELINES
1. All wiring must comply with local and national electrical Regulations
and must be installed by a Qualified electrician.
2. All electrical connections must be made according to the Electrical
Connection 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
immediately. 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, install a surge 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 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. Ensure cables do not 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 metre away from any combustible materials.
WARNING
BEFORE PERFORMING ANY ELECTRICAL OR WIRING WORK,
ISOLATE MAIN POWER TO THE SYSTEM.

Step 6: Connect signal cable
The signal cable enables communication between the indoor and
outdoor units. You must first choose the right cable size before preparing
it for connection.
Cable Types
•
Indoor Power Cable
(if applicable): H05VV-F or H05V2V2-F
•
Outdoor Power Cable
: H07RN-F

Table 2.
CABLE SIZE
The size of the power supply cable, signal cable, fuse and switch needed
is determined by the maximum current of the unit. The maximum current
is indicated on the nameplate located on the side panel of the unit. Refer
to this nameplate to choose the right cable, fuse or switch.
TAKE NOTE OF FUSE SPECIFICATIONS
The air conditioner’s circuit board (PCB) is designed with a fuse to
provide overcurrent protection. The specifications of the fuse are
printed on the circuit board, such as:
Indoor unit
: T5A/250VAC
Outdoor unit
(applicable to that adopt R32 refrigerant only):
•
for 5.3KW models and under a 20amp fuse single phase power
supply
•
for 5.4kw models and above use 30amp fuse 240v supply.
NOTE:
The fuse is made of ceramic.
1. Prepare the cable for connection:
a. Using wire strippers, strip the rubber jacket from both ends of
signal cable to reveal about 40mm of the wires inside.
b. Strip the insulation from the ends of the wires.
c. Using wire crimper, crimp u-type 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.
