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.
Make sure that you earth the cables.
- Do not connect the earth wire to the gas pipe, water pipe, lighting rod or telephone wire. If earthing is not
complete, electric shock or re may occur.
Install the circuit breaker.
- If the circuit breaker is not installed, electric shock or re may occur.
Make sure that the condensed water dripping from the drain hose runs out properly and safely.
Install the power cable and communication cable of the indoor and outdoor unit at least 1m away from the electric appliance.
Install the indoor unit away from lighting apparatus using the ballast.
- If you use the wireless remote control, reception error may occur due to the ballast of the lighting apparatus.
Do not install the air conditioner in following places.
- Place where there is mineral oil or arsenic acid. Resin parts ame and the accessories may drop or water may
leak. The capacity of the heat exchanger may reduce or the air conditioner may be out of order.
- The place where corrosive gas such as sulfurous acid gas generates from the vent pipe or air outlet.
The copper pipe or connection pipe may corrode and refrigerant may leak.
- The place where there is a machine that generates electromagnetic waves. The air conditioner may not operate
normally due to control system.

Purging the unit
On delivery, the indoor unit is loaded with an inert Nitrogen
gas. All this gas must therefore be purged before connecting
the assembly piping. To purge the inert gas, proceed as follows.
1
Unscrew the caps at the end of each pipe.
Result: All inert gas escapes from the indoor unit.
Note To prevent dirt or foreign objects from getting
into the pipes during installation, do NOT
remove the caps completely until you are
ready to connect the piping.
There are two refrigerant pipes of differing diameters:
A smaller one for the liquid refrigerant
A larger one for the gas refrigerant
The inside of copper pipe must be clean & has no dust.
1
Before connecting the refrigerant pipe, open the cover
side.
2
Remove the pinch pipe on the pipes and connect the
assembly pipes to each pipe, tightening the nuts, first
manually and then with a torque wrench, a spanner
applying the following torque.
Outer Diameter Torque (kgf•cm)
6.35 mm (1/4") 145~175
9.52 mm (3/8") 333~407
12.70 mm (1/2") 505~615
15.88 mm (5/8") 630~769
Note Must apply refrigerant oil on the flaring area to
prevent a leak.
