Specifications; What To Do Before Operation - Daikin RXYQ5PY1 Service Manual

Operation Manual
Wrong cleaning may make the plastics parts broken or cause fail-
ure of water leakage or electric shock.
Do not touch the air inlet or aluminium fin of the air condi-
tioner.
Otherwise, injury may be caused.
Do not place objects in direct proximity of the outdoor unit
and do not let leaves and other debris accumulate around the
unit.
Leaves are a hotbed for small animals which can enter the unit.
Once in the unit, such animals can cause malfunctions, smoke or
fire when making contact with electrical parts.
