The dehumidifying capacity of this unit is 68 pints per day. 
The patented self-evaporating function of the ARC-101CS 
unit fully exhausts all condensation automatically in most en-
vironments when humidity is less than 70%. Areas with more 
than 70% humidity, the self-evaporating function can still ex-
haust about 98% of the moisture and the remaining 2% of 
moisture will be collected in the water tank of the air condi-
tioner.
When the water reservoir reaches its maximum level, the unit 
will beep 8 times and the digital display will show P1. When 
the unit displays P1, all operation modes will be disabled 
temporarily, while the fan continuously running. The P1 code 
will disappear when the water is completely drained. 
• Continuous drainage (Fig. 1a)
Remove the upper drain plug from the back of the unit and
install the drain hose. Place the open end of the hose to a
drain area in a downward direction with gravity. This method
is recommended if uninterrupted op-eration is desired.
• Manual drainage (Fig. 1b)
Carefully move the unit to a drain location, remove the bot-
tom drain plug and let the water drain. Replace the drain plug
and plug in unit to resume operation.
