Wiring
Prepare the power source for exclusive with the air conditioner.
The supply voltage must comply with the rated voltage of the air conditioner. The plug socket shall be accessible after
installation.
Remark: All the wiring must be based on the wiring nameplate which is shown on the model.

• Never modify the unit by removing any of the safety guards or by bypassing any of the safety interlock swithces.
• Connect the connecting cable correctly and connect the connecting cable to terminal as identified with their
respective marks.
• Do not scratch the conductive core & inner insulator of power supply cables and do not deform or smash on
the surface of cables.
NOTE
Remark per EMC Directive 89/336/EEC
To prevent flicker impressions during the start of the compressor (technical process), following installation conditions
do apply.
1. The power connection for the air conditioner has to be done at the main power distribution.
The distribution has to be of a low impedance, normally the required impedance reaches at a 32 A fusing
point.
2. No other equipment has to be connected with this power line.
3. For detailed installation acceptance, please refer to your contract with the power supplier if restrictions do apply
for products like washing machines, air conditioner or electrical ovens.
4. For power details of the air conditioner, refer to the rating plate of the product.
5. For any question, contact your local dealer.
• Perform the wiring with sufficient capacity. Installation places legally require a short circuit isolator to be attached
to prevent electrical shock.
• Do not extend the power cable code by cutting.
• Power voltage should be in the range of 90%-110% of rated voltage.
• The plug of the air conditioner takes a grounding leg, and clients should use a grounding socket so that the air
conditioner can be grounded efficiently.
• If the power cord is damaged, replacement should be conducted by qualified technician or a serviceman.
