4.5 Drainage test
4.5.1Drainage without drain pump
After finishing drainpipe installation, pour some water into the water receiver plate to check if the
water flows smoothly.
4.5.2 Drainage with drain pump
①
Poke the Water Level Switch, remove the cover, use water pipe to pour 2000ml water into
the water receipt plate through the water inlet.
②
Turn on the power to Cooling operation. Check the pump’s operation and switch on the
Water Level Switch. Check the pump’s sound and look into the transparent hard pipe in the outlet at the
same time to check if the water can discharge normally.
③
Stop the air conditioner running, turn off the power, and put back the cover.

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 will
stop. Turn off the power and drain the remained water, and then turn on 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.
