Stop the air conditioner. After 3 minutes, check if it has abnormity. If the collocation of drainpipes is
illogical, the water will flow back overfull, which will cause the alarm lamp flashes, even overflow from
the water receipt plate.

Keep on pouring water until it gives an alarm signal for high water level, check if the pump drains water
at once. If the water level can
’
t fall below the alarmed water level after 3 minutes, the air conditioner

Note: the drain stuff in the main water receipt plate is for maintenance. Stuff up the drain stuff to prevent
water leakage.
