RNING

s

Installation must be carried out by the qualified installe

r.

If you install the system by yourself, it may cause serious t

rouble such as 

water leaks, electric shocks, fi

re and personal injur

y, as a 

result of a system 

malfunction. Do not carry out the installation and maintenance work except 

the by qualified installe

r.

s

Install the system in full acco

rdance with the installation manual.

Incor

rect installation may cause bursts, personal injur

y, water leaks, electric 

shocks and fi

re.

s

Be su

re to use only for household and 

residence.

If this appliance is installed in inferior envi

ronment such as machine shop 

and etc., it can cause malfunction. 

s

Use the original accessories and the specified components for 

installation.

If parts other than those p

rescribed by us a

re used, It may cause water 

leaks, electric shocks, fi

re and personal injury.

s

Install the unit in a location with good support.

Unsuitable installation locations can cause the unit to fall and cause 

material damage and personal injury.

s

Ventilate the working a

rea well in the event of 

refrigerant leakage 

during installation.

If the 

refrigerant comes into contact with naked flames, poisonous gas is 

pr

oduced.

s

When installing in small 

rooms, take p

revention measu

res not to 

exceed the density limit of 

refrigerant in the event of leakage, 

refer

red by the formula (acco

rdance with ISO5149). 

If the density of 

refrigerant exceeds the limit, please consult the dealer and 

install the ventilation system, otherwise lack of oxygen can occu

r, which 

can cause serious accident. 

s

After completed installation, check that no 

refrigerant leaks f

rom

the system.

If

refrigerant leaks into the 

room and comes into contact with an oven or 

other hot surface, poisonous gas is p

roduced.

s

Use the p

rescribed pipes, fla

re nuts and tools for R410A.

Using existing parts (for R22 or R407C) can cause the unit failu

re and 

serious accidents due to burst of the 

refrigerant ci

rcuit.

s

Tighten the fla

re nut by to

rque w

rench with specified method.

If the fla

re nut we

re tightened with excess to

rque, this may cause burst and 

refrigerant leakage after a long period.

s

The electrical installation must be carried out by the qualified 

electrician in acco

rdance with “the norm for electrical work” and 

“national wiring 

regulation”, and the system must be connected to 

the dedicated ci

rcuit.

Power supply with insu

fficient capacity and incor

rect function done by 

imp

roper work can cause electric shocks and fi

re.

s

Be su

re to shut o

ff the power befo

re starting electrical work.

Failu

re to shut o

ff the power can cause electric shocks, unit failu

re or 

incor

rect function of equipment.

s

Be su

re to use the cables conformed to safety standa

rd and cable 

ampacity for power distribution work. 

Unconformable cables can cause electric leak, anomalous heat p

roduction

or fi

re.

s

This appliance must be connected to main power supply by means 

of a ci

rcuit b

reaker or switch (fuse:16A) with a contact separation of 

at least 3mm. 

s

When plugging this appliance, a plug conforming to the norm 

IEC60884-1 must be used.

s

Use the p

rescribed cables for electrical connection, tighten the 

cables secu

rely in terminal block and 

relieve the cables cor

rectly to 

p

revent overloading the terminal blocks.

Loose connections or cable mountings can cause anomalous heat 

pr

oduction or fi

re.

s

Arrange the wiring in the cont

rol box so that it cannot be pushed up 

further into the box. Install the service panel cor

rectly.

Incor

rect installation may 

result in overheating and fi

re.

s

Be su

re to switch o

ff the power supply in the event of installation, 

inspection or servicing.

If the power supply is not shut o

ff, the

re is a risk of electric shocks, unit 

failu

re or personal injury due to the unexpected start of fan.

s

Be su

re to wear p

rotective goggles and gloves while at work.

s

Earth leakage b

reaker must be installed.

If the earth leakage b

reaker is not installed, it can cause electric shocks.

CAUTION

s

Use the ci

rcuit b

reaker of cor

rect capacity. Ci

rcuit b

reaker should 

be the one that disconnect all poles under over cur

rent.

Using the incor

rect one could cause the system failu

re and fi

re.

s

Install isolator or disconnect switch on the power supply wiring in 

acco

rdance with the local codes and 

regulations.

The isolator should be locked in OFF state in acco

rdance with EN60204-1.

s

Be su

re to install indoor unit p

roperly acco

rding to the installation 

manual in o

rder to run o

ff the drainage smoothly.

Imp

roper installation of indoor unit can cause d

ropping water into the 

room

and damaging personal p

roperty.

s

Install the drainage pipe to run o

ff drainage secu

rely acco

rding to 

the installation manual.

Incor

rect installation of the drainage pipe can cause d

ropping water into the 

room and damaging personal p

roperty.

s

Be su

re to install the drainage pipe with descending slope of 1/100 

or mo

re, and not to make traps and ai

r-bleedings.

Check if the drainage runs o

ff secu

rely during commissioning and ensu

re

the space for inspection and maintenance. 

s

Secu

re a space for installation, inspection and maintenance 

specified in the manual.

Insu

fficient space can 

result in accident such as personal injury due to 

falling f

rom the installation place.

s

For installation work, be ca

reful not to get inju

red with the heat 

exchange

r, piping fla

re portion or sc

rews etc.

s

Be su

re to insulate the 

refrigerant pipes so as not to condense the 

ambient air moistu

re on them.

Insu

fficient insulation can cause condensation, which can lead to moistu

re

damage on the ceiling, floo

r, fu

ffect medical 

equipment and telecommunication equipment, and obstruct its function or 

cause jamming.

s

Do not place any variables which will be damaged by getting wet 

under the indoor unit.

When the 

relative humidity is higher than 80% or drainage pipe is clogged, 

condensation or drainage water can d

valuables.

s

Do not install the wireless

s

Do not use the unit for special purposes such as storing foods, 

cooling p

s

Do not touch any buttons with wet hands.

It can cause electric shocks.

s

Do not touch any 

refrigerant pipes with your hands when the 

system is in operation.

During operation the 

refrigerant pipes become ext

remely hot or ext

frost injury.

s

Carry out the electrical work for g

round lead with ca

re.

Do not connect the g

round lead to the gas line, water line, lightning conductor or telephone line

’s g

s

Do not put the drainage pipe di

rectly into drainage channels whe

re

poisonous gases such as sulphide gas can occu

Poisonous gases will flow into the 

room th

rough drainage pipe and 

seriously a

ffect the user

’s health and safety. This can also cause the 

cor

s

Ensu

re that no air enters in the 

refrigerant ci

rcuit when the unit is 

installed and 

removed.

If air enters in the 

refrigerant ci

becomes too high, which can cause burst and personal injury.

s

Do not p
