IMPORTANT SAFETY INSTRUCTIONS

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

WARNING

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.

CAUTION This symbol shows that the operation manual should be read carefully.

CAUTION

This symbol shows that a service personnel should be handling this 
equipment with reference to the installation manual.

CAUTION

This symbol shows that information is available such as the operating
manual or installation manual.

1.Transport of equipment containing flammable refrigerants

2.Marking of equipment using signs

3.Disposal of equipment using flammable refrigerants

4.Storage of equipment/appliances

5.Storage of packed (unsold) equipment

6.Information on servicing

See transport regulations

See local regulations

See national regulations.

The storage of equipment should be in accordance with the manufacturer's instructions.

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.

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
