Shortening Of "Maintenance Cycle" And "Replacement Cycle" Needs To Be Considered In Following Situations - Daikin RXYCQ8A7Y1B Operation Manual

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 non-combustible, 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.
■
Recommended inspection and maintenance cycles
Be aware that the mentioned maintenance and replacement cycles
do not relate to the warranty period of the components.
