Daikin VRV 5-S Series Installation And Operation Manual page 15

WARNING
▪ Do not modify, disassemble, remove,
reinstall or repair the unit yourself as
incorrect dismantling or installation
may cause an electric shock or fire.
Contact your dealer.
▪ In case of accidental refrigerant
leaks, make sure there are no naked
flames. The refrigerant itself is
entirely safe, non-toxic and mildly
flammable, but it will generate toxic
gas when it accidentally leaks into a
room where combustible air from fan
heaters, gas cookers, etc. is present.
Always have qualified service
personnel confirm that the point of
leakage has been repaired or
corrected before resuming operation.
WARNING
▪ Do NOT pierce or burn refrigerant
cycle parts.
▪ Do NOT use cleaning materials or
means to accelerate the defrosting
process other than those
recommended by the manufacturer.
▪ Be aware that the refrigerant inside
the system is odourless.
WARNING
The appliance shall be stored in a
room without continuously operating
ignition sources (example: open
flames, an operating gas appliance or

mildly flammable. For compliance with the requirements for
enhanced tightness refrigerating systems and IEC60335-2-40 the
installer must take extra measures. For more information, see
"2.1 Instructions for equipment using R32
The indoor unit part of this VRV 5-S heat pump system can be used
for heating/cooling applications. The type of indoor unit which can be
used depends on the outdoor units series.
