Monobloc Type
Design and installation
1. Refrigerant R32
The refrigerant R32 has the higher efficiency and more friendly for environment in comparison with R410A. It has
a lower GWP (Global Warming Potential) value, and higher efficiency than R410A. The Ozone Depletion Potential
(ODP) of R32 is 0, and Global Warming Potential(GWP) is 675.
Refrigerant piping consists of copper/steel pipes, joints, and other fittings. All components must be selected and
installed in conformity with the standards pertaining to the Refrigeration Safety Regulation. Same piping as for
R410A can be used.
WARNING
• This product contains fluorinated greenhouse gases (Refrigerant type : R32). Do NOT emit refrigerant gases
into the atmosphere.
• The refrigerant R32 is Slightly Flammable gas. But it does not leak normally. If the refrigerant leaks in the
installed place and contact with burning energy, it may cause fire, or a harmful gas.
• If there are some leak, turn off any combustible devices, ventilate the installed place, and contact the dealer from
which you purchased the unit. Do not use the unit until the refrigerant leaked is repaired.
• Only use R32 as refrigerant. Other substances may cause explosions and accidents.
CAUTION
• The wall thickness of the piping should comply with the relevant local and national regulations for the designed
pressure.
• For high-pressure refrigerant, any unapproved pipe must not be used.
• Do not heat pipes more than necessary to prevent them from softening.
