The DSC 90S is a high capacity dehumidifier. It is ideal for tight spaces
dehumidification.
Overview
Applications
Humidity is the cause of dampness, stuffiness or odor in the
basement or crawlspace. Failure to control the humidity levels with
not only cause structural damage like wood rot or wood warping, but
will also create the perfect environment for allergens like mold, and
mildew to grow.
Most homeowners tend to ignore the humidity levels in the
crawlspace or basements, however, research from the American
Lung Association has proven that moisture, odor, and allergens in
these spaces can easily spread out to the entire house.

PRINCIPLE OF OPERATION
For future reference, write down the model, serial number, and date of purchase for your
dehumidifier.
This is extremely helpful if you need to seek assistance in the future. The data label on the
side of your unit has the key characteristics of your specific unit.
The Sentinel Series Dehumidifiers utilizes its integral humidistat to monitor the conditioned
space.When the relative humidity goes above the selected set point, the dehumidifier will
energize. Air is 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.
For aditional questions concerming your dehumildifer, the following options
are available:

WARRANTY REGISTRATION
SAFETY NOTES
Congratulations on purchasing a new Sentinel Dehumidifier. Your new dehumidifier
comes with an extensive warranty plan. To register, simply fill out and return the
warranty form provided in the dehumidfier box.
Be sure to note your dehumidifier serial number as you will need it for registration.
The Sentinel Series Dehumidifier must always be connected using a grounded electrical
connection (as required for all electrical appliances). If non-grounded wiring is used, all
liability reverts to owner and the warranty is voided.
Sentinel Dehumidifiers should only be maintained and repaired by a qualified
technician.
Sentinel Dehumidifiers are only intended for operation when oriented with the unit stting
on its feet and level. Operating the unit in any other orientation could allow water to
flood electrical components.
If there is a chance that water flooded the dehumidifier, it should be opened and allowed
to dry thoroughly before reconnecting to electrical power and restarting.
To ensure proper operation, neither the inlet nor discharge should be positioned against
a wall. The inlet requires a minimum of 12”clearance and the discharge requires a
minimum of 36" clearance.
The best option for proper diffusion of air throughout the room is to have the discharge
blowing away from a wall and the inlet pulling air in parallel to a wall.
Always unplug the dehumidifier before moving.
Do not insert your fingers or any object into the inlet or discharge.
AlI work on the dehumidifier should be done with the unit “off” and unplugged.
Do not use water to clean the exterior of the machine. To clean unit, unplug from power,
then use a damp cloth to wipe exterior.
Do not stand on the machine or use it as a device to hang clothes.

INSTALLATION
The area to be controlled should be sealed with a vapor barrier. If unit is installed in a
crawlspace,all vents should be sealed.
Do not install your dehumidifier in a corrosive environment. Some liquid vapor
barriers dry via“solvent evaporation". Always make sure that barrier is
completely dry and area is throughly ventilated before installing dehumidifier.
WARNING
STEP #1: PLACE DEHUMIDIFIER ON A LEVEL SURFACE.
NOTE: Do not place directly on vapor barrier. Elevation is required to allow the condensate
water to drain via gravity.
If the unit is handled in such a manner that the compressor did not remain in the upright
position,you will need to place it on a level surface, then wait a minimum of 2 hours before
turning“on”.
INDICATOR LIGHTS
ARROW BUTTONS
Use the up and down arrow button to set the desired humidity setpoint on the display screen.
The setpoint can be any number between 36-90%. Creating a setpoint means that when
the indoor humidity is lower than the set point, the machine will stop automatically.
Conversely, when the indoor humidity is higher than the set level, the unit will operate.
NOTE: The humidty levels displayed are approximate only (+/- 5%)
CONTINUOUS MODE
To switch into continuous mode, set the humidity below 36%. At this point the Cont.light
should iluminate green on the display board to indicate you have succesfully switched to
continuous mode. The display screen will show“CO".
When set to continuous, the dehumidifier will run constantly, regardless of the humidity
level.To stop the dehumidifier from running, turn the unit off or switch back to normal
humidistat operation. To swtich back to normal humidistat operation, simply move the
setpoint above 36%.
CENTRAL CONTROL
This mode is not applicable on the PureAiro DSC 90S.
AUXILLARY TERMINALS A5/A6
The A5/A6 on the terminal strip can be used as a safety switch for external condensate
pumps.It should be set to N/O (normally open) at the dehumidifier. If an E4 error codes,
switch the wiring to N/C (normally closed).
HUMIDITY DISPLAY SCREEN
The display screen has two functions:
POWER INDICATOR LIGHT
CONTINUOUS MODE/AUTODEFROST LIGHT
This light indicates that the unit is properly powered on and ready to operate. Always make
sure the unit is "off" prior to performing any service.
When this light iluminates green, it indicates that the dehumidifer is set to continuous
operation mode.
1. When the unit is powered on, it shows the humidity of the space.
2. While setting the desired humidity level, the screen wil show the set humidity. After a brief
delay,the display will revert to current humidity level.
When the light glows red, it means the unit is in auto defrost mode and clearing the
evaporator coil of any ice buildup.
STEP #2: SET UP DRAIN LINE
The drain line should be routed to a suitable drain on the outside. It must flow down to the
drain without any loops, dips, or valleys.
STEP #3: PLUG UNIT INTO 15 AMP GROUNDED CIRCUIT.
Use this button to turn the dehumidifier on and off. Press once to turn machine on. You will
hear 2 beeps and the light will illuminate green. Press the power button a second time and
you will hear one beep as the machine shuts down. Note that there is a one minute fan delay
on shutdown.

Drain Tube- 12 inches Long.12 mm OD.
Cut a piece of 3/4" OD PVC that is approx. 6”long.
Insert the open end of the tubing into the 3/4" pipe so that it does not extend into the elbow
fitting. For proper flow, a minimum downward slope of 1”per 10' run is required.
(Note: If a proper downward angle is not possible, then it is recommended to use a
PureAiro DSC 90S which includes an integrated pump. Alternatively you can use an
external condensate pump).
Support the PVC tubing so that it maintains a
smooth downward flow to drain.
Always test the drain before leaving the
installation area.

REMOTE CONTROL INSTRUCTIONS
Sentinel Dehumidifiers can be controlled using an optional remote accessory.The Sentinel
Remote Control connects to your Sentinel Series Dehumidifier via a 25' CAT 5 cable. The
remote control contains an integrated sensor which gives you multiple options for remotely
controlling your unit, in addition to monitoring the conditions surrounding the dehumidifer.
One application for the remote control is to install the dehumidifier in one room with the
conditioned air ducted into a second room that contains the remote. For example, the
dehumidifier could be installed in a laundry room and ducted into a living room. The remote
would then be mounted in the living room so the remote sensor can control the humidity and
provide easy controls for the user.
Another useful application for the remote control is if the dehumidifier is in area that's
difficult to access on a regular basis. For instance, if your dehumidifier is installed in your
crawl space, the remote could be mounted in your living space or garage. This provides you
with an easy way to monitor the dehumidifier.
NOTE: Symbols indicated below will only appear when the dehumidifier is powered on.
Press the on/off button and the
machine will start running (two
beeps). Press the button again to
turn the machine off.
Use the Up and Down arrow
buttons to adjust the humidity
level.
