Installation
When you use the unit as an air conditioner or a dehumidifier, the hot air must
be exhausted out of the room to complete the air exchange of the condenser.
When the unit is operating in fan-only mode, no exhaust is required.
If you use this portable air conditioner in cooling mode without venting the
exhaust hose to the outside of the room that you are cooling, the temperature
in the room will not be cooled because the hot air is still coming out from the
rear of the unit even when the front of the unit is blowing cool air.
Exhaust hose Installation
The exhaust hose must be installed onto the unit.
1. Pull out about 6” of one end of the exhaust hose.
2. Screw the exhaust connector on the exhaust hose in a clockwise motion.
3. Snap the exhaust connector in place in the back of the unit.

Leakage Current Detection and Interruption Plug Testing
This unit is provided with a Leakage Current Detection and Interruption
(L.C.D.I.) built into the plug of the power supply cord. This device provides
protection to reduce risk of fire due to arcing faults in the power supply cord.
Before use, follow the Plug Testing Instructions to ensure that the (LCDI)
circuit is functioning properly:

COOLING
1) Plug the Power Cord to the power outlet.
2) Turn on the unit by pressing the ON/OFF Button.
3) Press Mode Button until the icon next to “COOL” turns on.
4) Set the thermostat using the Temperature / Timer buttons. The thermostat
is adjustable between 64oF-90oF.
5) Select the fan speed by pressing the Fan Speed Selection Button.
The cooling mode cools and dehumidifies the air. If the ambient temperature
drops below the set temperature, the compressor turns off and the unit
switches to the Fan only mode. When the temperature rises above the set
temperature, the compressor turns on again.
DEHUMIDIFYING
1) Plug the Power Cord to the power outlet.
2) Turn on the unit by pressing the ON/OFF Button.
3) Press Mode Button until the icon next to “DRY” turns on.
During the dehumidifying mode, the unit will condense water out of the air and
exhaust it through the exhaust hose. The ambient temperature in the room
may drop by a few degrees.
The fan always run on low speed while in the dehumidifying mode. If you do
not use the exhaust hose, you will need to manually drain the water from the
unit. The dehumidifying mode will not work in temperatures below 64oF.
FAN ONLY
1) Plug the Power Cord to the power outlet.
2) Turn on the unit by pressing the ON/OFF Button .
3) Press Mode Button until the icon next to “FAN” turns on.
4) Select the fan speed by pressing the Fan Speed Selection Button.
No temperature setting is needed for fan-only mode. Also, fan-only mode does
not require that the exhaust hose be attached.

15
WATER DRAINAGE
All portable air conditioners dehumidify the air as they cool. This Whynter SNO
portable air conditioner is designed to evaporate and exhaust the condensed
water. When using the Cooling or Dehumidifying modes under extremely
humid conditioners, the internal water tray may be filled completely. If this
happens, the Water Level indicator on the control panel will light and the
compressor will shut off. The unit will continue to operate and exhaust water
until the water level drops. Then the compressor will come back on and the unit
will begin cooling. If you do not want to wait for the unit to exhaust the water
out, you can manually drain the water from the unit.
If continuous drainage option is not used, please insert the second rubber
stopper to the upper drain port.
Manual Drainage:
Turn the unit off., unscrew the drain cap and/or the rubber stopper from the
upper drain port. Then connect the drain hose to the upper drain port and put
the other end of the drain hose in a container. Turn the unit back on and the
internal drain pump will pump the water out. When the flow of the water stops,
you can turn off the unit. Remove the drain hose and screw the drain cap
and/or the rubber stopper on. Turn the unit on and it will begin cooling and
dehumidifying again.
Note: If no water comes out from the upper drain port, drain the water from the
lower drain port.

16
If the provided water hose is not long enough, you can drain by using a garden hose. The
diameter of the outer port is designed to fit the screw nut of a regular garden hose.

17
Maintenance
Make sure the unit is turned off and unplugged before
performing any maintenance.
Do not immerse the unit in water or other liquids.
Do not pour liquids into the unit.
Some parts of the unit may have shape edges, be careful when
handling those parts.
FILTER
This portable air conditioner comes with a washable filter that filters dust or
other impurities in the air. This filter should be cleaned about once every two
weeks or as needed. If it becomes clogged with dust, the airflow volume will
reduce and the cooling efficiency will be lower.
1. Remove filter from the filter compartment in front of the unit.
2. Wash the air filter by immersing it into warm water (not above104 F) and
gently scrubbing it with a gentle soap.
3. Rinse the filter and dry it thoroughly before putting it back into the unit.
If the filter is torn or unusable, order a new filter by calling our service
department.
EXTERIOR
Clean the plastic parts of the unit with a slightly damp cloth.
Clean the stainless steel parts of the unit with stainless steel cleaner.
Never use strong chemicals, oil-based products, detergents to clean the unit.
