Safety precautions
Installing the unit
IMPORTANT: When installing the unit, always remember to connect rst the refrigerant tubes, then the electrical lines.
Upon receipt, inspect the product to verify that it has not been damaged during transport. If the product appears
damaged, DO NOT INSTALL it and immediately report the damage to the carrier or retailer (if the installer or the
authorized technician has collected the material from the retailer.)
After completing the installation, always carry out a functional test and provide the instructions on how to operate the air
conditioner to the user.
Do not use the air conditioner in environments with hazardous substances or close to equipment that release free ames
to avoid the occurrence of res, explosions or injuries.
Our units should be installed in compliance with the spaces shown in the installation manual, to ensure accessibility from
both sides and allow repairs or maintenance operations to be carried out. The unit’s components should be accessible
and easy to disassemble without endangering people and objects.
For this reason, when provisions of the installation manual are not complied with, the cost required to access and repair
the units (in SAFETY CONDITIONS, as set out in prevailing regulations) with harnesses, ladders, scaolding or any other
elevation system will NOT be considered part of the warranty and will be charged to the end customer.
Power supply line, fuse or circuit breaker
Always make sure that the power supply is compliant with current safety standards. Always install the air conditioner in
compliance with current local safety standards.
Always verify that a suitable grounding connection is available.
Verify that the voltage and frequency of the power supply comply with the specications and that the installed power is
sucient to ensure the operation of any other domestic appliance connected to the same electric lines.
Always verify that the cut-o and protection switches are suitably dimensioned.
Verify that the air conditioner is connected to the power supply in accordance with the instructions provided in the
wiring diagram included in the manual.
Always verify that electric connections (cable entry, section of leads, protections…) are compliant with the electric
specications and with the instructions provided in the wiring scheme. Always verify that all connections comply with
the standards applicable to the installation of air conditioners.
Devices disconnected from the power supply should be completely disconnected in the condition of overvoltage
category.
Always disassemble the electric lines before the refrigerant tubes.

Deciding on where to install the outdoor unit
Outdoor Unit
The outdoor unit must not be placed on its side or upside down, as the compressor lubrication oil will run into the cooling
circuit and seriously damage the unit.
Choose a location that is dry and sunny, but not exposed to direct sunlight or strong winds.
Do not block any passageways or thoroughfares.
Choose a location where the noise of the air conditioner when running and the discharged air do not disturb any
neighbours.

• You should connect the power cable into the power cable terminal and fasten it with a clamp.
• The unbalanced power must be maintained within 2% of supply rating.
CAUTION
- If the power is unbalanced greatly, it may shorten the life of the condenser. If the unbalanced power is
exceeded over 4% of supply rating, the indoor unit is protected, stopped and the error mode indicates.
• To protect the product from water and possible shock, you should keep the power cable and the connection
cord of the indoor and outdoor units within ducts. (with appropriate IP rating and material selection for your
application)
• Ensure that main supply connection is made through a switch that disconnects all poles, with contact gap of a
least 3 mm.
• Devices disconnected from the power supply should be completely disconnected in the condition of
overvoltage category.
• Keep distances of 50mm or more between power cable and communication cable.

• When connecting cables, you can connect the cables to the electrical part or connect them through the holes
below depending on the spot.
CAUTION
• Run transmission wiring between the indoor and outdoor units through a conduit to protect against
external forces, and feed the conduit through the wall together with rergerant piping.
• Remove all burrs at the edge of the knock-out hole and secure the cable to the outdoor knock-out using lining
and bushing with an electrical insulation such as rubber and so on.
• Must keep the cable in a protection tube.
• Keep distances of 50mm or more between power cable and communication cable.
• When the cables are connected through the hole, remove the Plate bottom.
