WATER DRAINAGE

The dehumidifying capacity of this unit is pints per day. The patented self-evaporating function of the ARC-122DS unit fully exhausts all condensation automatically in most environments when humidity is less than 70%.In areas with more than 70% humidity, the self-evaporating function can still exhaust about 98% of the moisture and the remaining 2% of moisture will be collected in the water tank of the air conditioner.

When there is excess water condensation inside the unit, the air conditioner stops running and shows a warning light (refer to page 8). This warning light indicates that the water condensation needs to be drained using the following procedures:

• Manual drainage (Fig. 2a}
  Turn off the unit. Carefully roll the unit to a drain location or position a flat container, dish or optional drain bucket accessory (sold separately) under the drain area of the lower drain port. Remove the drain cover and rubber plug and the condensed water will drain out automatically. Once all the condensed water is drained, replace the drain rubber plug and cover into the drain firmly.
• Continuous Gravity drainage option (Fig. 2b}
  Remove the upper drain plug from the back of the unit and install the drain hose (sold separately). Place the open end of the hose to a drain area. This method is recommended if an uninterrupted operation is desired.

• Auto Pump drainage option (Fig. 2c} 
  This unit has a condensate pump feature that can pump out (and up)water through the included drain hose for continuous water removal. Remove the pump drain plug from the back of the unit and install the drain hose. Place the open end of the hose to a drain area.
