the growth of mold and mildew, and the micro-structured elec-
trostatically charged filtration media traps and retains particles.
The 3M Filter is pre-installed.
Note: The 3M Filter should be replaced every 2-3 months de-
pending on usage. Please contact [e-mail] for retail
sales information.
WATER DRAINAGE
The dehumidifying capacity of this unit is 71 pints per day. The patented self-evaporating function of the ARC-
148MHP unit fully exhausts all condensation automatically in most environments when humidity is less than 70%.
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 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 run-
ning. The P1 code will disappear when the water is completely drained.
• Manual drainage (Fig. 1a)
In AUTO, COOL, DRY, or HEAT mode, carefully move the unit to a drain location, remove the bottom drain plug
and let the water drain. Replace the drain plug and plug in unit to resume operation.
• Continuous drainage (Fig. 1b)
In AUTO, COOL or DRY mode, 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. This method is recommended if uninterrupted operation is de-
sired.
• Heat pump drainage (Fig. 1c)
This unit has a condensate pump feature that can pump out (and up) water through the included drain hose for
continuous water removal during HEAT Mode. Remove the heat pump drain plug from the back of the unit and
