Installation manual
● Cylinders shall be equipped with pressure relief valves and shut-off valves in a proper order.
● Empty recovery cylinders shall be evacuated and cooled before recovery.
● The recovery system shall operate normally according to the specified instructions and shall be
suitable for refrigerant recovery.
● In addition, the calibration scales shall operate normally.
● Hoses shall be equipped with leak-free disconnect couplings.
● Before starting the recovery, check for the status of the recovery system and sealing state. Consult
with the manufacturer if suspected.
● The recovered refrigerant shall be returned to the supplier in the correct recovery cylinders with the
Waste Transfer Note attached.
● Do not mix refrigerants in the recovery units or cylinders.
● If compressors or compressor oils are to be removed, make sure that they have been evacuated to
the acceptable level to ensure that flammable refrigerant does not remain in the lubricant.
● The evacuation process shall be performed before sending the compressor to the suppliers.
● Only the electrical heating to the compressor body is allowed to accelerate the process.
● Oil shall be drained safely from the system.
● For installation with handling the refrigerant (R-32), use dedicated tools and piping materials. Because
the pressure of the refrigerant, R-32 is approximately 1.6 times higher than that of R-22, failure to
use the dedicated tools and piping materials may cause rupture or injury. Furthermore, it may cause
serious accidents such as water leakage, electric shock, or fire.
● Never install a motor-driven equipment to prevent ignition.
● In case of a malfunction, immediately stop operation of the air conditioner and disconnect the entire
power system. Then consult the authorized service personnel.
