R32 Split series

4P600463-1C – 2020.08

WARNING

▪

Only use R32 as refrigerant. Other substances may cause explosions and

accidents.

▪

R32 contains fluorinated greenhouse gases. Its global warming potential (GWP)

value is 675. Do NOT vent these gases into the atmosphere.

▪

When charging refrigerant, ALWAYS use protective gloves and safety glasses.

CAUTION

▪

Do NOT use mineral oil on flared part.

▪

Do NOT reuse piping from previous installations.

▪

NEVER install a drier to this R32 unit to guarantee its lifetime. The drying material

may dissolve and damage the system.

CAUTION

▪

Use the flare nut fixed to the unit.

▪

To prevent gas leakage, apply refrigeration oil only to the inside of the flare. Use

refrigeration oil for R32.

▪

Do NOT reuse joints.

WARNING

Connect the refrigerant piping securely before running the compressor. If the

refrigerant piping is NOT connected and the stop valve is open when the compressor

is run, air will be sucked in. This will cause abnormal pressure in the refrigeration

cycle, which may result in equipment damage and even injury.

CAUTION

▪

Incomplete flaring may cause refrigerant gas leakage.

▪

Do NOT re-use flares. Use new flares to prevent refrigerant gas leakage.

▪

Use flare nuts that are included with the unit. Using different flare nuts may

cause refrigerant gas leakage.

Charging refrigerant (see

WARNING

The refrigerant inside the unit is mildly flammable, but normally does NOT leak. If the

refrigerant leaks in the room and comes in contact with fire from a burner, a heater,

or a cooker, this may result in fire, or the formation of a harmful gas.

Turn off any combustible heating devices, ventilate the room, and contact the dealer

where you purchased the unit.

Do NOT use the unit until a service person confirms that the part from which the

refrigerant leaked has been repaired.

WARNING

NEVER directly touch any accidental leaking refrigerant. This could result in severe

wounds caused by frostbite.
