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 using your hands.
6. After connecting the copper pipes to the indoor
unit, wrap the power cable, signal cable and the
piping together with binding tape.
DO NOT intertwine signal cable with other wires.
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.
Check that there is no leakage of refrigerant after completing installation operations.
In the event of leakage of refrigerant, immediately ventilate the area and evacuate the system.
3 - WIRING
•
All wiring must comply with local and national electrical codes, regulations and must be
installed by a licensed electrician.
•
All electrical connections must be made according to the Electrical Connection Diagram
located on the panels of the indoor and outdoor units.
•
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.
•
Power voltage should be within 90-110% of rated voltage. Insufficient power supply can
cause malfunction, electrical shock, or re.
•
Only connect the unit to an individual branch circuit outlet. Do not connect another appli-
ance to that outlet.
•
Make sure to properly ground the air conditioner.
•
Every wire must be firmly connected. Loose wiring can cause the terminal to overheat,
resulting in product malfunction and possible re.
•
Do not let wires touch or rest against refrigerant tubing, the compressor, or any moving
parts within the unit.
•
If the unit has an auxiliary electric heater, it must be installed at least 1 meter away from
any combustible materials.
•
Make sure that you do not cross your electrical wiring with your signal wiring.
•
This may cause distortion and interference.
•
The unit must be connected to the main outlet. Normally, the power supply must have a
impedance of 32 ohms.
•
No other equipment should be connected to the same power circuit.
•
Connect the outdoor wires before connecting the indoor wires.
MAKE SURE THAT:
•
The power supply voltage and frequency values respect that specified on the appliance
data plate.
•
The power supply line has an effective earth connection and it is correctly dimensioned
for maximum absorption of the climate control unit.
•
A suitable omnipolar disconnection device must be envisioned on the appliance mains
electric power supply, in compliance with the national installation rules.
