INSTALLATION
WARNING: NEVER OPERATE THE AIR CONDITIONER
WITHOUT THE AIR FILTER
AIR FILTERS
• Silvershield Pre-filter
This portable air conditioner is equipped with a
Silvershield pre-filter, which removes large particles such as
dust, pet hair and dander. This pre-filter can be removed for
cleaning by pulling the filter frame back and out.
• 3M™ Antimicrobial High Air Flow Filter
This portable air conditioner comes with the 3M™ Antimicrobial
High Air Flow Filter which is designed to remove particles such
as dust, pet hair and dander, antimicrobial agent helps inhibit
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.
WATER DRAINAGE
The dehumidifying capacity of this unit is 71 pints per day.
The patented self-evaporating function of the ARC-148MS
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.
• Manual drainage (Fig. 1a)
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.
• Continuous drainage (Fig. 1b)
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 op-
eration is desired.

OPERATION INSTRUCTIONS
BEFORE USING YOUR APPLIANCE
 Remove the exterior and interior packing
 Before connecting the appliance to the power source, let it stand upright for approximately 4 hours. This will reduce
the possibility of a malfunction in the cooling system from handling during transportation
SWITCHING ON/OFF THE AIR CONDITIONER
The appliance can be switched ON or OFF by pressing the POWER button on the control panel or the ON/OFF but-
ton on the remote control
COOLING MODE
In this mode, the air conditioner cools and dehumidifies the room. To activate this function mode, press the MODE
button until the COOL indicator light comes on. When the cooling mode is set, the compressor will start in approxi-
mately 3 minutes. In cooling mode, hot air is exhausted from the outdoor exhaust port and the exhaust hose must be
connected to exhaust out the hot air.
The temperature setting range of this air conditioner is from 62°F / 17°C to 88°F / 30°C. To set the temperature,
press the + or - buttons. This air conditioner has a 5°F temperature cushion which if the set temperature is within 5°F
of the ambient temperature, the unit runs on fan only mode. This saves energy and prolongs the life of the compres-
sor of the air conditioner.
To set the fan speed, press the FAN button. In cooling mode, the difference in noise level between the 4 fan speeds
is not very noticeable when the compressor is on. Try setting the unit to Fan only mode, you should be able to hear
the difference between high and low fan speed settings.

In this mode, the air conditioner only dehumidifies the room, the compressor will activate intermittently depending on
the ambient temperature and the fan speed is set to LOW. To activate this function mode, press the MODE button
until the DRY indicator light comes on. Please note that when switching function mode, there will be an approxi-
mately 3 minute transition time. In dehumidifying mode, do not connect the exhaust hose and let the warm air return
to the room.
AUTOMATIC MODE
When you set the air conditioner in AUTO mode, it will automatically select cooling or fan only operation depending
on what temperature you have selected and the room temperature is close to the unit. The fan speed is automatically
selected and cannot be changed .To operate the unit in Auto mode when the unit is on, press the MODE button until
the AUTO indicator light comes on.
FAN ONLY MODE
In this mode, only the fan of the air conditioner runs and circulates the air in the room. To activate this function mode,
press the MODE button until the FAN indicator light comes on. In this function mode, the temperature cannot be
set. Subsequently, set the desired fan speed by pressing the FAN button. Fan Only mode requires that the exhaust
hose be removed.
TIMER (DELAYED SWITCH ON / OFF) FUNCTION
This function mode enables a delayed switch ON or delayed switch OFF of the air conditioner. The time (hours) de-
lay can be set, enabled and disabled.
