2. Turn on the unit in COOLING mode. You will hear
the drain pump.Check whether the water is discharged
properly (a 1-minute lag is possible, depending on the
length of the drain pipe), Check whether water leaks from
the joints.
3. Turn off the air conditioner and put the cap back on.
• After turn off the air conditioner 3 minutes, check
whether there is anything abnormal. If drainage
pipes have not been distributed properly, over
back-flow water shall cause the flashing of alarm
indicator at remote-controlled receiving board and
even water shall run over the water collector.
• Continuously infusing water until water level
alarmed, check whether the drainage pump could
discharge water at once. If water level does not
decline under warning water level 3 minutes
later, it shall cause shutdown of unit. When this
situation happens, the normal startup only can
be recovered by turning down power supply and
eliminating accumulated water.
Note: Drain plug at the main water-containing plate
is used for eliminating accumulated water in water-
containing plate when maintaining air conditioner fault.
During normal operation, the plug shall be filled in to
prevent leakage.
