Wiring
CAUTION
•
Ensure to wrap insulation around the piping. Direct contact with the
bare piping may result in burns or frostbite.
•
Make sure the pipe is properly connected. Overtightening may dam-
age the bell mouth and undertightening may lead to leakage.
NOTE ON MINIMUM BEND RADIUS
Carefully bend the tubing in the middle according to the diagram below.
DO NOT
bend the tubing more than 90° or more than 3 times.
Bend the pipe with thumb
min-radius 10 cm (3.9”)
Fig. 21.
6. After connecting the copper pipes to the indoor unit, wrap the
power cable, signal cable and the piping together with binding tape.
NOTE:
DO NOT
intertwine signal cable with other wires. While bundling these
items together, do not intertwine or cross the signal cable with any other
wiring.
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 ensure there is no refrigerant leak after completing the
installation work. If there is a refrigerant leak, ventilate the area
immediately and evacuate the system (refer to the
Air Evacuation
section
of this manual).

Safety Precautions
WARNING
•
Ensure to disconnect the power supply before working on the unit.
•
All electrical wiring must be done according to local and national
regulations.
•
Electrical wiring must be done by a qualified personnel. Improper
connections may cause electrical malfunction, injury and fire.
•
An independent circuit and single outlet must be used for this unit.
DO NOT
plug another appliance or charger into the same outlet. If
the electrical circuit capacity is not enough or there is a defect in the
electrical work, it can lead to shock, fire, unit and property damage.
•
Connect the power cable to the terminals and fasten it with a clamp.
An insecure connection may cause fire.
•
Ensure that all wiring is done correctly and the control board cover
is properly installed. Failure to do so can cause overheating at the
connection points, fire, and electrical shock.
•
Ensure that the main supply connection is made through a switch
that disconnects all poles, with contact gap of a least 3 mm.
•
DO NOT
modify the length of the power cable or use an extension
cord.
CAUTION
•
Connect the outdoor wires before connecting the indoor wires.
•
Ensure you earth the unit. The earthing wire should be away from
gas pipes, water pipes, lightning rods, telephone or other earthing
wires. Incorrect earthing may cause electrical shock.
•
DO NOT
connect the unit with the power source until all wiring and
piping is completed.
•
Ensure that you do not cross your electrical wiring with your signal
wiring, as this can cause distortion and interference.
Follow these instructions to prevent distortion when the compressor
starts:
•
The unit must be connected to the main outlet. Normally, the power
supply must have a low output impedance of 32 ohms.
•
No other equipment should be connected to the same power circuit.
•
The unit’s power information can be found on the rating sticker on
the product.
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:
Outdoor unit:
•
For 7.1KW models and under 20amp fuse, 240V
•
For models 8KW and above use 30amp Fuse, 240V
NOTE:
The fuse is made of ceramic.
