When deciding on the location of the air conditioner with the owner, the following restrictions must be taken into account.
1. Determine the position of the pipe and drain hose hole as seen in the
picture and drill the hole with an inner diameter of 65mm so that it slants
slightly downwards.
2. Insert bolt anchors, use existing ceiling supports or construct a suitable
support as shown in gure.
3. Install the suspension bolts depending on the ceiling type.
4. Screw eight nuts to the suspension bolts making space for hanging the
indoor unit.
5. Hang the indoor unit to the suspension bolts between two nuts.
6. Screw the nuts to suspend the unit. Cut a pad stopper and place it on the
bracket at this time.
7. Adjust the unit to the appropriate position considering the installation area
for the front panel.

1. Remove the pinch pipe on the pipes and connect the assembly pipes to each pipe, tightening the nuts, rst manually
and then with a torque wrench, a spanner applying the following torque.
2. Must use insulator which is thick enough to cover the refrigerant tube to
protect the condensate water on the outside of pipe falling onto the oor
and the eciency of the unit will be better.
3. Cut o any excess foam insulation.
4. Be sure that there must be no crack or wave on the bended area.
5. It would be necessary to double the insulation thickness(0.39inch(10mm)
or more) to prevent condensation even on the insulator when if the
installed area is warm and humid.
6. Do not use joints or extensions for the pipes that connect the indoor and outdoor unit. The only permitted connections
are those for which the units are designed.

Cutting/Flaring the pipes
1. Make sure that you have the required tools available. (pipe cutter, reamer, aring tool and pipe holder)
2. If you wish to shorten the pipes, cut it with a pipe cutter, taking care to ensure that the cut edge remains at a 90° angle
with the side of the pipe. Refer to the illustrations below for examples of edges cut correctly and incorrectly.
3. To prevent any gas from leaking out, remove all burrs at the cut edge of the pipe, using a reamer.
4. Slide a are nut on to the pipe and modify the are.
5. Check that the aring is correct, referring to the illustrations below for examples of incorrect aring.
6. Align the pipes and tighten the are nuts rst manually and then with a torque wrench, applying the following torque.

Performing leak test & insulation
To identify potential gas leaks on the indoor unit, inspect the connection area
of each refrigerant pipe using a leak detector for R410A.
Before recreating the vacuum and recirculating the refrigerant gas, it is
advisable to pressurize the whole system with nitrogen (using a cylinder with
pressure reducer) at a pressure above 40 bar in order to immediately detect
leaks on the refrigerant ttings.
Made vacuum for 15 minutes and pressurising system with nitrogen.
Once you have checked that there are no leaks in the system, you can insulate the piping and hose.
1
To avoid condensation problems, place T13.0(0.51") or thicker Acrylonitrile
Butadien Rubber separately around each refrigerant pipe.
2 Wind insulating tape around the pipes and drain hose avoiding to compress
the insulation too much.
3
Finish wrapping insulating tape around the rest of the pipes leading to the outdoor unit.
4 The pipes and electrical cables connecting the indoor unit with the outdoor
unit must be xed to the wall with suitable ducts.
5 Select the insulation of the refrigerant pipe.
XInsulate the gas side and liquid side pipe referring to the thickness
according to the pipe size.

X
Select the power cable in accordance with relevant local and national regulations.
X
Wire size must comply with local and national code.
X
For the power cable, use the grade of H07RN-F or H05RN-F materials.
X
You should connect the power cable into the power cable terminal
and fasten it with a clamp.
X
The unbalanced power must be maintained within 10% of supply
rating among whole indoor units.
X If the power is unbalanced greatly, it may shorten the life of the
condenser. If the unbalanced power is exceeded over 10% of supply
rating, the indoor unit is protected, stopped and the error mode
indicates.
X
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 in the iron pipe.
X
Connect the power cable to the auxiliary circuit breaker.
An all pole disconnection from the power supply must be incorporated in the fixed
wiring[≥1/8"(3mm)].
X
You must keep the cable in a protection tube.
X
Keep distances of 2"(50mm) or more between power cable and
communication cable.
X Maximum length of power cables are decided within 10% of power drop. If it
exceeds, you must consider another power supplying
method.
X
The circuit breaker(ELCB or MCCB+ELB) should be considered more capacity if many
indoor units are connected from one breaker.
X
Use round pressure terminal for connections to the power terminal block.
X
For wiring, use the designated power cable and connect it firmly,
then secure to prevent outside pressure being exerted on the terminal board.
X
Use an appropriate screwdriver for tightening the terminal screws. A screwdriver
with a small head will strip the head and make proper tightening impossible.
X
Over-tightening the terminal screws may break them.
X
See the table below for tightening torque for the terminal screws.
