5.5 Drainage test
5.5.1
Drainage without drain pump
After finishing drainpipe installation, pour some water into the water plate to check if the water flows smoothly.
5.5.2
Drainage with drain pump
5.5.2.1
Poke the Water Level Switch, remove the cover, and use water pipe to pour 2000ml water into the
water plate through the water inlet.
5.5.2.2
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.
5.5.2.3
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 circumfluence
from the water 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 (means this indoor unit stops, stand-by, but the outdoor unit still work if there is
capacity requirement). Turn off the power and drain the remained water, then turn on the air
conditioner.
Note:
the drain stopper in the main water plate is for maintenance. Stuff up the drain stopper to prevent water leakage.
