Warranty Registration
Safety Notes
Congratulations on purchasing a new Guardian Dehumidifier.Your new dehumidifier
comes with an extensive warranty plan.To register, simply fill out and return the warranty
form provided in your dehumidifier box.
Be sure to note your dehumidifier serial number as you will need it for registration.
The Guardian 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 the owner , and the warranty is voided.
Guardian Dehumidifiers should only be maintained and repaired by a qualified technician.
Always unplug the dehumidifier before moving it to another location.
lf 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 6” clearance and the discharge requires a
minimum of 6" clearance.
For better use of the dehumidifier, both air inlet and air outlet should be
facing the open area of the space.
Do not insert your fingers or any objects into the inlet or discharge.
All work on the dehumidifier should be done with the unit“off”and unplugged.
Do not use water to clean the exterior.To clean the unit, unplug from power, then use
a damp cloth to wipe the exterior.
Do not stand on the machine or use it as a device to hang clothes.
GuardianDehumidifiers are only intended for operation when oriented with the unit sitting
on its feet and level.Operating the unit in any other orientation could allow water to flood
electrical components.

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 yourunit has the key characteristics of your specific unit.
For additional questions concerning your dehumidifier, the following options are available:

Power Supply: 115V,60 Hz AC, Single Phase
Outlet Requirement: 3-Prong, GFCI
ircuit Protector: 15 Amp
The Guardian Series Dehumidifiers utilizes its integral humidistat to monitor the conditioned
space. When the relative humidity goes above the selected setpoint, the dehumidifier will energize
air is drawn across an evaporator coil, which is cooler than the dew point of the 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.
The area to be controlled should be sealed with a vapor barrier. lf the 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 the barrier is completely dry and
the area is thoroughly
240 Volts AC may cause serious injury from electric shock.
To reduce risk of injury:
1. Disconnect electrical power before servicing.
2.Only plug the unit into a grounded electric circuit.
3. Do not use an extension cord.
4. Do not use a plug adapter.

Do not place the unit directly on the vapor barrier.For example , use blocks or pavers to create a level
surface.
lf 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".
The included drain line attaches to the unit via a compression type fitting on the discharge end of
the unit.To attach drain line, remove the compression nut and slide it over the end of the hose to
be attached to unit. Slide compression nut side of hose over the insert on the compression fitting
completely. Tighten compression nut.

To switch into a continuous mode, simply use the down arrow key to set the humidity below
36%.At this point the Cont.light should illuminate green on the display board to indicate you
have successfully switched to continuous mode.The display screen will show "Co".
When set to continuous, the dehumidifier will run constantly, regardless of the humidity level until
you turn the unit off or switch back to normal humidistat operation. If you would like to switch back
to normal humidistat operation, simply move the setpoint above 36%.
This mode is not applicable on the Guardian SNS90.

For extended storage or movement of the machine, press the "Drain”button to remove water fro
mthe integral pump's reservoir.
When the pump reservoir water level is too high, the high water sensor will activate to prevent over-
flow.When this occurs, the dehumidifier will stop the compressor automatically and the display will
show “E4".After a 1 minute delay, the fan motor will turn off and the machine will not operate until
the problem is resolved.To reset the unit after an“E4” error, check the pump to verify it is functioning,
then unplug the unit for two minutes.
The display screen has two functions:
This light indicates that the unit is properly powered on and ready to operate. Always make sure the
unit is “off” prior to the performing any service.
When the power light is blinking, it means that the unit has reached the humidity setpoint.
When this light illuminates green, it indicates that the dehumidifier is set to the continuous operation mode.
When the compressor light glows red, it indicates the compressor has been initiated but is
currently warming up.
Once the compressor light switches to green, it indicates the compressor is in working status.
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.
Guardian Dehumidifiers can be controlled that using an optional remote accessory.The Guardian
Remote Control connects to your Guardian Series Dehumidifier via a 25' CAT 5 cable.The Remote
control contains an integrated sensor that gives you multiple options for remotely controlling your
unit, in addition to monitoring the conditions surrounding the dehumidifier.
When the light glows red, it means the unit is in auto defrost mode and clearing the evaporator coil
of any ice buildup.
1. When the unit is powered on, it shows the humidity of the space.
2. While setting the desired humidity level, the screen will show the set humidity. After a brief
delay, the display will revert to current humidity level.

3. Stop the machine
The Guardian SNS90 has both automatic and manual draining. During normal operation, the
Guardian SNS90 will automatically drain as required. lf you would like to store or move the
machine, you may press the drain button to drain the water from the pump reservoir. The
drain will operate for 15 seconds each time the button is pushed. lt may be necessary
to push the drain button more than once to completely empty the reservoir.
4. Water Drainage
Use this button if the unit will not be in use for an extended period of time.Pressing the drain pump button will remove
water from the pump reservoir, so the unit can be safely moved or stored.

Ducted Applications
Ducting Installation
Ducting the dehumidifier allows the unit to be in one room while conditioning an adjacent room. The
supply grille is designed for 6" flex ducting. Be sure to secure the ducting with a tie wrap. Also, keep
in mind that the supply ducting can be screwed into an adapter if necessary.
Note: The supply duct adapter is standard on all units.
Maximum length for ducting= 6'
lf it is necessary to remove the
adapter, place hand at bottom of
the adapter and use your hands to
lift out and down.This will remove
the cover hooks from the machine.
Removing Duct Adapter
To install adapter, line it up with
holes on the side of the unit and
push it up from the base of the
adapter.
lnstalling Duct Adapter
Rotate the flex duct counter-
clockwise.
Flex Duct Installation
Rotate flex duct clockwise or
remove wire tie.
