concerning use of the appliance in a

safe way and understand the hazards

involved.

Children SHALL NOT play with the

appliance.

Cleaning and user maintenance

SHALL NOT be made by children

without supervision.

WARNING

To prevent electrical shocks or fire:

▪ Do NOT rinse the unit.

▪ Do NOT operate the unit with wet

hands.

▪ Do NOT place any objects containing

water on the unit.

CAUTION

▪ Do NOT place any objects or

equipment on top of the unit.

▪ Do NOT sit, climb or stand on the

unit.

▪ Units are marked with the following symbol:

This means that electrical and electronic products may NOT be

mixed with unsorted household waste. Do NOT try to dismantle

the system yourself: dismantling the system, treatment of the

refrigerant, of oil and of other parts MUST be done by an

authorised installer and MUST comply with applicable legislation.

Units MUST be treated at a specialised treatment facility for reuse,

recycling and recovery. By ensuring this product is disposed of

correctly, you will help to prevent potential negative consequences

for the environment and human health. For more information,

contact your installer or local authority.

heavy metal above a certain concentration.

Possible chemical symbols are: Pb: lead (>0.004%).

Waste batteries MUST be treated at a specialised treatment

facility for reuse. By ensuring waste batteries are disposed of

correctly, you will help to prevent potential negative consequences

for the environment and human health.

3.2 Instructions for safe operation

WARNING

▪ Do NOT modify, disassemble,

remove, reinstall or repair the unit

yourself as incorrect dismantling or

installation may cause an electrical

shock or fire. Contact your dealer.

▪ In case of accidental refrigerant

leaks, make sure there are no naked

flames. The refrigerant itself is

entirely safe, non-toxic and non-

combustible, but it will generate toxic

gas when it accidentally leaks into a

room where combustion air from fan

heaters, gas cookers, etc. is present.

ALWAYS have qualified service

personnel confirm that the point of

leakage has been repaired or

corrected before resuming operation.

CAUTION

▪ NEVER touch the internal parts of the

controller.

▪ Do NOT remove the front panel.

Some parts inside are dangerous to

touch and appliance problems may

happen. For checking and adjusting

the internal parts, contact your

dealer.

WARNING

This unit contains electrical and hot

parts.

WARNING

Before operating the unit, be sure the

installation has been carried out

correctly by an installer.

CAUTION

It is unhealthy to expose your body to

the air flow for a long time.

CAUTION

To avoid oxygen deficiency, ventilate

the room sufficiently if equipment with

burner is used together with the

system.

FXFQ20~125BVEB

VRV system air conditioner

4P540926-1F – 2023.06

CAUTION

Do NOT operate the system when

using a room fumigation-type

insecticide. Chemicals could collect in

the unit, and endanger the health of

people who are hypersensitive to

chemicals.

WARNING

NEVER touch the air outlet or the

horizontal blades while the swing flap

is in operation. Fingers may become

caught or the unit may break down.

CAUTION

NEVER expose little children, plants or

animals directly to the airflow.

WARNING

Do NOT place a flammable spray

bottle near the air conditioner and do

NOT use sprays near the unit. Doing

so may result in a fire.

Maintenance and service (see "7Maintenance and

service"[410])

CAUTION: Pay attention to the fan!

It is dangerous to inspect the unit while

the fan is running.

Make sure to turn OFF the main switch

before executing any maintenance

task.

CAUTION

Do NOT insert fingers, rods or other

objects into the air inlet or outlet. When

the fan is rotating at high speed, it will

cause injury.

WARNING

NEVER replace a fuse with a fuse of a

wrong ampere ratings or other wires

when a fuse blows out. Use of wire or

copper wire may cause the unit to

break down or cause a fire.

CAUTION

After a long use, check the unit stand

and fitting for damage. If damaged, the

unit may fall and result in injury.

DANGER: RISK OF

ELECTROCUTION

To clean the air conditioner or air filter,

be sure to stop operation and turn all

power supplies OFF. Otherwise, an

electrical shock and injury may result.

WARNING

Be careful with ladders when working

in high places.

CAUTION

Turn off the unit before cleaning the air

filter, suction grille, air outlet and

outside panels.

CAUTION

Before accessing terminal devices,

make sure to interrupt all power supply.

WARNING

Do NOT let the indoor unit get wet.

Possible consequence: Electrical

shock or fire.

DANGER: RISK OF

ELECTROCUTION

Disconnect the power supply for more

than 10minutes, and measure the

voltage at the terminals of main circuit

capacitors or electrical components

before servicing. The voltage MUST be

less than 50VDC before you can

touch electrical components. For the

location of the terminals, see the

warning label for persons performing

service and maintenance.

About the refrigerant (see [

"7.3About the refrigerant" 411])

WARNING

▪ The refrigerant in the system is safe

and normally does NOT leak. If the

refrigerant leaks in the room, contact

with a fire of a burner, a heater or a

cooker may result in a harmful gas.

▪ Turn OFF any combustible heating

devices, ventilate the room and

contact the dealer where you

purchased the unit.

6.2 About operation modes

INFORMATION

Depending on the installed system, some operation modes

will not be available.

▪ The air flow rate may adjust itself depending on the room
