Do not use the dehumidifier in standing water. If there is a chance that the dehumidifier
has been flooded, unplug the unit, remove the cover, and allow it to dry completely before
proceeding.
Do not insert objects or your fingers into the inlet or discharge.
Your dehumidifier should only be repaired by a qualified technician.
Unless otherwise noted, all maintenance should be done with the unit powered off.
Always connect your dehumidifier using a grounded electrical connection(as required for
all electrical appliances). The use of non-grounded wiring will void the warranty.
Do not use water to clean the exterior of the dehumidifier. To clean unit,unplug from
power, then use a damp cloth to wipe the exterior.
Do not stand on dehumidifier or place objects on it.
Do not use with extension cord or plug adapter.

If unit has been turned or flipped so that the compressor did not remain upright, place the
unit on a level surface and wait a minimum of 2 hours before proceeding.
Slide the side of hose with compression nut over the insert on the compression fitting
completely.
Tighten compression nut.
INSTALLATION REQUIREMENTS
The area where the dehumidifier is located should be sealed with a vapor barrier.
If the unit is installed in a crawl space, all vents should be sealed.
For proper ventilation, neither the inlet or discharge should be positioned against a wall.
The inlet needs a minimum of 12" clearance and the discharge requires a minimum of
36" clearance.
For the best air diffusion, install the unit so that a side panel faces the wall.
PureAiro dehumidifiers are only intended for operation when the unit is upright and level
with the feet on the ground.
HOW IT WORKS
PureAiro dehumidifiers use an integrated humidistat to monitor theconditioned space.
When the relative humidity goes above the selected setpoint, the dehumidifier will energize.
Air is then drawn across an evaporator coil, which is cooler than the dew point of air. This
means moisture will condense out of the air. The air is then reheated through the condenser
coil and distributed back into the room.

INDICATOR LIGHTS
Humidity Display Screen
The display screen has two functions:
1
2Power Indicator Light
Continuous Mode/ Auto Defrost Light
This light indicates that the unit is properly powered on and ready to operate.
3
1. When the unit is powered on, it shows the humidity of the space
2. When setting the desired humidity level, the screen will show the set point.
Always make sure the unit is “off” prior to performing any service, unless otherwise
indicated.
If the humidity is above the setpoint, the light will be solid green and the machine will
operate.
After a brief delay, it will revert to current humidity of the space.
If the humidity is below the setpoint, the unit will be in standby mode and the light will be
flashing.
When the light illuminates green, it indicates that the dehumidifier is set to continuous
operation mode.
When the light illuminates red, it means the unit is in auto defrost mode and clearing the
evaporator coils of any ice buildup.
Compressor Light
4
When the light illuminates red, it indicates the compressor has been initiated but is
currently warming up.
Once the light switches to green, it means the compressor is currently in working status.
REMOTE CONTROL INSTRUCTIONS
PureAiro Dehumidifiers can be controlled using an optional remote accessory. The remote
connects to your dehumidifier via a 25’ CAT 5 cable, with the integrated sensor giving you
multiple options for monitoring surrounding conditions.
Example #1- Install the dehumidifier in the laundry room and duct it into the living room.
Mount the remote in the living room and use the remote sensor.
Example #2- Install the dehumidifier in your crawl space with the remote mounted in your
garage.

PUMP MAINTENANCE
Your PureAiro DSC 120ES is equipped with an integral condensate pump designed to
pump water from the dehumidifier out to the desired drain.
The pump requires routine maintenance that is not covered by the warranty.
Preventative maintenance is necessary to prevent issues from dirt and slime that may
accumulate in the drain system. This includes the drain pan, hose to the condensate
pump,pump reservoir, pump head assembly, and discharge tubing.
