Page 7: Safety Precautions
SAFETY PRECAUTIONS Safety Precautions Precautions for using R32 refrigerant The basic installation work procedures are the same as the conventional refrigerant (R22 or R410A). However, pay attention to the following points: WARNING 1 Transportation of equipment containing flammable refrigerants Pay attention to the fact that additional transportation regulations may exist with respect to equipment containing flammable gas. The maximum number of pieces of equipment or the configuration of the equipment permitted to be transported together will be determined by the applicable transport regulations. - Page 8 SAFETY PRECAUTIONS 6.6. 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.
- Page 9 SAFETY PRECAUTIONS The use of silicone sealants may inhibit the effectiveness of some types of leak detection equipment. Intrinsically NOTE: safe components do not have to be isolated prior to working on them. 8 Repairing intrinsically safe components • Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current for the equipment in use.
- Page 10 SAFETY PRECAUTIONS 13 Charging procedures • In addition to conventional charging procedures, the following requirements shall be followed: Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimise the amount of refrigerant contained in them. Cylinders shall be kept upright.
- Page 11 SAFETY PRECAUTIONS • Hoses shall be complete with leak-free disconnect couplings and in good condition. • Before using the recovery machine, check that it is in satisfactory working order, has been properly maintained and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. •...

Page 12: Composition Of The Air Conditioner
COMPOSITION OF THE AIR CONDITIONER Explanation of symbols displayed on the indoor unit or outdoor unit This symbol shows that this appliance uses a flammable refrigerant. WA R N I N G If the refrigerant is leaked and exposed to an external ignition source, there is a risk of fire. - Page 13 COMPOSITION OF THE AIR CONDITIONER Remote Controller (Optional) You can control the air conditioner with the wired controller or remote controller. It is used for power ON/OFF, setting the operation mode, temperature, fan speed, etc. There are different types of remote controllers that can be used. Operation instruction will be further specified in remote controller’s manual.
