A. IMPORTANT SAFETY AND GENERAL INFORMATION

A.3 Warning For Using R32 Refrigerant

For R32 refrigerant models:

1. Appliance shall be installed, operated and stored in a room with a ﬂoor

area larger than 43 sq ft.

2. Appliance shall not be installed in an unventilated space, if that space is

smaller than 43 sq ft.

3. Compliance with national gas regulations shall be observed.

4. Keep ventilation openings clear of obstruction.

5. The appliance shall be stored so as to prevent mechanical damage from

occurring.

6. A warning that the appliance shall be stored in a well-ventilated area

where the room size corresponds to the room area as speciﬁed for

operation.

7. Any person who is involved with working on or opening a refrigerant

system must be certiﬁed for reﬁgerant handling as required by local, state,

and federal regulations.

8. Servicing shall only be performed as recommended by the equipment

manufacturer. Maintenance and repair requiring the assistance of other

skilled personnel shall be carried out under the supervision of the person

competent in the use of ﬂammable refrigerants.

9. Please follow the instruction carefully to handle, install, clear, and

service the air conditioner to avoid any damage or hazard. Flammable

Refrigerant R32 is used within air conditioner. When maintaining or

disposing the air conditioner, the refrigerant (R32) shall be recovered

properly, and shall not be discharged to air directly.

10. No any open ﬁre or device like a switch which may generate spark/

arcing shall be around the air conditioner to avoid causing ignition of the

ﬂammable refrigerant used.

11. Please follow the instruction carefully to store or maintain the air

conditioner to prevent mechanical damage from occurring.

12. Flammable refrigerant R32 is used in air conditioner. Please follow the

instruction carefully to avoid any hazard.

13. For speciﬁc information on the type of gas and the amount of

refrigerant used, refer to the model nameplate on the unit.

CAUTION: Risk of ﬁre/ﬂammable materials

(Required for R32 units only)

WARNING: low burning velocity material

(For R32 models apply to IEC60335-2-40:2018)

Note about Fluorinated Gases

1. Fluorinated greenhouse gases are contained in hermetically sealed

equipment. For speciﬁc information on the type, the amount and the Co2

equivalent in tonnes of the ﬂuorinated greenhouse gas(on some models),

please refer to the relevant label on the unit itself.

2. Installation, service, maintenance and repair of this unit must be

performed by a certiﬁed technician.

3. Product uninstallation and recycling must be performed by a certiﬁed

technician.

For Household Use Only Read And Save These Instructions

1. Transport of equipment containing ﬂammable refrigerants:

See transport regulations.

2. Marking of equipment using signs:

See local regulations.

3. Disposal of equipment using ﬂammable refrigerants:

See national regulations.

4. Storage of equipment/appliances:

The storage of equipment should be in accordance with the manufacturer’s

instructions.

5. Storage of packed (unsold) equipment:

Storage package protection should be constructed such that mechanical

damage to the equipment inside the package will not cause a leak of

the refrigerant charge. The maximum number of pieces of equipment

permitted to be stored together will be determined by local regulations.

6. Information on servicing:

1) Checks to the area:

Prior to beginning work on systems containing ﬂammable refrigerants,

safety checks are necessary to ensure that the risk of ignition is minimized.

For repair to the refrigerating system, the following precautions shall be

complied with prior to conducting work on the system.

2) Work procedure:

Work shall be undertaken under a controlled procedure so as to minimize

the risk of a ﬂammable gas or vapour being present while the work is

being performed.

3) General work area:

All maintenance staff and others working in the local area shall be

instructed on the nature of work being carried out. Work in conﬁned spaces

shall be avoided. The area around the workspace shall be sectioned off.

Ensure that the conditions within the area have been made safe by control

of ﬂammable material.

4) Checking for presence of refrigerant:

The area shall be checked with an appropriate refrigerant detector prior to

and during work, to ensure the technician is aware of potentially ﬂammable

atmospheres. Ensure that the leak detection equipment being used is

suitable for use with ﬂammable refrigerants, i.e. non-sparking, adequately

sealed or intrinsically safe.

5) Presence of ﬁre extinguisher:

If any hot work is to be conducted on the refrigeration equipment or

any associated parts, appropriate ﬁre extinguishing equipment shall be

available to hand. Have a dry powder or CO2 ﬁre extinguisher adjacent to

the charging area.

6) No ignition sources:

No person carrying out work in relation to a refrigeration system which

involves exposing any pipe work that contains or has contained ﬂammable

refrigerant shall use any sources of ignition in such a manner that it may

lead to the risk of ﬁre or explosion. All possible

ignition sources, including cigarette smoking, should be kept sufﬁciently far

away from the site of installation, repairing, removing and disposal, during

which ﬂammable refrigerant can possibly be released to the surrounding

space. Prior to work taking place,

the area around the equipment is to be surveyed to make sure that there

are no ﬂammable hazards or ignition risks. No Smoking signs shall be

displayed.

7) Ventilated area:

Ensure that the area is in the open or that it is adequately ventilated

before breaking into the system or conducting any hot work. A degree

of ventilation shall continue during the period that the work is carried

out. The ventilation should safely disperse any released refrigerant and

preferably expel it externally into the atmosphere.

8) Checks to the refrigeration equipment:

Where electrical components are being changed, they shall be ﬁt for the

purpose and to the correct speciﬁcation. At all times the manufacturer’s

maintenance and service guidelines shall be followed. If in doubt consult

the manufacturer’s technical department for assistance. The following

checks shall be applied to installations using ﬂammable refrigerants:

a. The charge size is in accordance with the room size within which the

refrigerant containing

parts are installed;

b. The ventilation machinery and outlets are operating adequately and are

not obstructed;

c. If an indirect refrigerating circuit is being used, the secondary circuit

shall be checked for the presence of refrigerant; Marking to the equipment

continues to be visible and legible. Markings and signs that are illegible

shall be corrected;

d. Refrigeration pipe or components are installed in a position where they

are unlikely to be exposed to any substance which may corrode refrigerant

containing components, unless the components are constructed of

materials which are inherently resistant to being corroded or are suitably

protected against being so corroded.

9) Checks to electrical devices:

Repair and maintenance to electrical components shall include initial

safety checks and component inspection procedures. If a fault exists that

could compromise safety, then no electrical supply shall be connected to

the circuit until it is satisfactorily dealt with. If the fault cannot be corrected

immediately but it is necessary to continue operation, an adequate

temporary solution shall be used. This shall be reported to the owner of

the equipment so all parties are advised. Initial safety checks shall include:

a. That capacitors are discharged: this shall be done in a safe manner to

avoid possibility of sparking;

b. That there no live electrical components and wiring are exposed while
