    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 Attention is drawn to the fact that additional transportation regulations may exist with respect to equipment containing flammable gas.
  • 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 capacitive 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. •...

    OPERATION MANUAL Operation Manual  Special Remarks • 3-minute protection after compressor stop To protect compressor, it will be off for at least 3 minutes once it is stopped. • 5-minute protection Compressor must run for at least 5 minutes once it is operated. During these 5 minutes, compressor will not stop even if the room temperature reaches the set temperature unless you use remote control switch to turn off the unit (all indoor units can be turned off by user).
  • Page 16 OPERATION MANUAL 4 This is Not Abnormal • Smell from indoor unit Smell adheres on indoor unit after a long period of time. Clean the air filter and panels or allow a good ventilation. • Sound from Deforming Parts During system starting or stopping, a sound might be heard. However, this is due to thermal deformation of plastic parts. It is not abnormal.
