RXF20~ARXF20~42E5V1B
R32 split series
4P519439-21V – 2022.10

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.

CAUTION

Do NOT open the valves before flaring is complete. This would cause refrigerant gas
leakage.

DANGER: RISK OF EXPLOSION

Do NOT open the stop valves before the vacuum drying is finished.

Charging refrigerant (see 

"7.4 Charging refrigerant"

 [

 41]

)

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

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.

NOTICE

To avoid compressor breakdown, do NOT charge more than the specified amount of
refrigerant.

WARNING

NEVER  directly  touch  any  accidental  leaking  refrigerant.  This  could  result  in  severe
wounds caused by frostbite.

"8 Electrical installation"

WARNING

The appliance MUST be installed in accordance with national wiring regulations.
