IMPORTANT NOTE: Read this manual carefully before installing or

operating your new air conditioning unit. Make sure to save this

manual for future reference.

Explanation of symbols displayed on the unit(For the unit adopts R32/R290 Refrigerant only):

This symbol shows that this appliance used a flammable refrigerant. If the

refrigerant is leaked and exposed to an external ignition source, there is a risk of fire.

This symbol shows that the operation manual should be read carefully.
This symbol shows that a service personnel should be handling this 

equipment with reference to the installation manual.
This symbol shows that information is available such as the operating

manual or installation manual.

Warnings(for using R290/R32 refrigerant only)

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 minimised. 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 minimise 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: 

The charge size is in accordance with the room size within 

which the refrigerant containing parts are installed; 

The ventilation machinery and outlets are operating 

adequately and are not obstructed;

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; 

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:  

That capacitors are discharged: this shall be done in a 

safe manner to avoid possibility of sparking; 

That there no live electrical components and wiring are
