*****IMPORTANT*****
READ FIRST BEFORE OPERATING UNIT
BEFORE OPERATING:
IMPORTANT! The power switch must be in the “OFF” position before
it is plugged in. The error light will illuminate if the switch is in the “ON”
position before it is plugged in the wall because the safety circuit has not
been initialized.
The standard operating temperature for the Atlantic LGR is 58 ºF degrees to
120 ºF. The unit will freeze below 58 ºF. Units stored in cold areas could
cause the coils to frost, and when plugged in, the unit may immediately go
into defrost mode (indicated by the blue light on the control panel). This is
normal. To prevent a leak, properly place the discharge hose into a
receptacle before the unit goes into automatic pump out mode.
AFTER OPERATING:
Please keep in mind that coils may still be cold at the end of each use. Keep
the unit plugged in and the discharge hose in a receptacle. Allow the unit to
thaw thoroughly until the side of the unit is no longer cold to touch. Press
the purge switch to completely empty the pump reservoir. If the condensate
pump is not properly purged after the last use, or if the unit is removed from
the job site before the coils return to room temperature, the condensate pump
may begin to pump water immediately when the unit is plugged in at the
next job site causing a leak if the discharge hose is not placed in a
receptacle.
Please be sure that unit goes through defrost mode completely to ensure that
the evaporator coil is properly thawed, and that collected water in the pump
is fully purged. Unplugging the unit before the evaporator coil is fully
defrosted could cause water to collect in the pump and overflow causing a
leak.

Congratulations on your purchase of the
Atlantic LGR dehumidifier. Please
carefully read the operation and
maintenance instructions prior to operating
the unit. Following these instructions will
ensure proper operation, transportation and
storage of the Atlantic LGR. This will
maximize the performance and minimize
occurrences of misuse that may result in
unnecessary service and repairs and
shorten the operating life of the unit.
SAFETY INFORMATION
Caution!
Unit operates on alternating current:
110/120 volt, 60 Hz
Or 230 volt, 50 Hz
Do not operate your Atlantic LGR
Dehumidifier with a cut or frayed power
cord. Do not unplug your dehumidifier
by pulling on its cord. Grasp the plug
firmly and pull it out of the wall socket.
The plug has a safety ground pin
installed that must not be removed. If
the pin is damaged or missing, have the
power cord replaced at once. Visually
inspect the power cord before each use.
Ignoring these safety precautions may
result in a fire or an electric shock.
Never operate electrical equipment in
standing water. There is a shock hazard.
Never drop the unit. Sudden and severe
impact may result in damage to internal
components.
Your Atlantic LGR Dehumidifier should
not be operated with the unit’s outer
cover removed. Personal injury may
result.
Drapes or other loose fabrics can be
drawn against the unit restricting its
airflow. This condition may cause the
unit to overheat. Assure that there is
sufficient space between the back of the
unit and these fabrics to avoid this
condition.
Save the shipping carton in case your
Atlantic LGR Dehumidifier must be
returned for repair. Discard the plastic
bag to prevent children from using it as a
toy. Also, children should not be
allowed to play on or near a running
dehumidifier.
Never operate your Atlantic LGR
Dehumidifier outside when it is raining
and never store your dehumidifier
outside.
This unit should never be serviced or
cleaned while it is plugged into a live
electrical power source.
Warning!
Ignoring these safety precautions may
result in serious personal injury.
OPERATION
Inspection of unit: Upon delivery of your
Atlantic LGR dehumidifier, inspect the
packaging for signs of damage. If you
suspect any concealed damage, it is critical
that the damage be identified and noted
before you sign for the delivery. If this
procedure is followed the shipping claim is
between the freight company and the
company that hired the freight company to
deliver your unit. After the delivery
receipt is signed, the claim must be filed
by your company within 7 days.
Transportation of unit: The Atlantic
LGR dehumidifier MUST be transported
in the vertical, operating position. The
unit may be placed in a horizontal position
on its back for loading and unloading
purposes only. Transporting the unit in
this position puts undue stress on the
refrigeration components and tubing and
can also cause significant damage to these
parts. If the unit has been in a horizontal
position prior to use, place the unit upright
and wait for 60 minutes before starting the
unit.

Electrical requirements: The Atlantic
LGR dehumidifier will plug into a
grounded 15 amp outlet. If used in wet
conditions a ground fault interrupter (GFI)
outlet or attachment is required for safe
operation. The unit draws 7.5 amps at 80
ºF, 60 %RH (AHAM conditions). When
operated at higher humidity and
temperatures the amp draw will increase.
When operated at cooler or drier
conditions the amp draw will decrease.
Set-up for operation: To set-up the unit
for operation, place the unit in an upright
position normally located in the center of
the area to be dehumidified. Connect the
40’ drain hose to the drain hose lead
located at the bottom of the control panel.
Run the drain hose to a permanent drain or
water tight container. Plug the power cord
into the dehumidifier and then into a
grounded 15 amp outlet.
Before turning the unit on, check that the
pleated media air filter is in place and in
proper operating condition. If ducting is
going to be attached to the Atlantic LGR,
this should be performed prior to turning
the unit on.
To turn the unit on, push the power switch.
The power lamp on the control panel
(green) will lighten. The fan will
immediately come on, and the compressor
will start. The low pressure control may
turn off the compressor if starting the unit
when it has been stored in cold conditions.
This is caused by the contraction of the
cold refrigerant. The low pressure control
prevents the compressor from operating
when there is insufficient refrigerant in the
system. Insufficient refrigerant will cause
damage to the compressor. A false low
charge may be sensed by the control if the
refrigerant is cold. The automatic restart
will switch the unit back on if the pressure
in the system increases. In extremely cold
conditions this may cycle a few times.
Be sure to properly purge remaining water
in the pump after each use. Please keep in
mind that coils may still be cold at the end
of each use. Allow the unit to adjust to
room temperature and press the purge
switch. If the condensate pump had not
been properly purged after the last use, or
if the unit had been removed from the
previous job site before the coils had
returned to room temperature, the
condensate pump may begin to pump
water immediately when the unit is
plugged in.
Control Panel
The control panel (picture below) contains
the power switch, hour meter, function
lamps, pump purge switch, power cord
connection, and drain hose lead. All of
these components are identified in the
picture.
The Hour meter displays the number of
hours of operation since the unit was built
to the tenth of an hour (six minutes).
The Power lamp (green) lights when the
power switch is on.
The Pump lamp (yellow) lights when the
condensate pump is engaged. This will
occur when the auto pump switch is
activated by the water level in the
condensate pump reservoir or when the
pump purge switch is pressed.
The Defrost lamp (blue) lights when the
unit enters a defrost cycle. The light will
go off when the defrost cycle is completed.
The Error lamp (red) will light if the
condensate pump safety switch is activated
by a failure of the auto pump function.
This safety switch will also turn off the
compressor, so the pump will not
overflow. The Error lamp will also light if
the low pressure switch senses low
pressure in the refrigeration system and
has turned off the compressor. This lamp
indicates a need for service.

Control Panel
MAINTENANCE
Warning!
Disconnect the unit from the power
supply before cleaning or servicing.
Filter Cleaning: The pleated air filter
must be checked regularly. The filter
itself should be vacuumed frequently to
control the build-up of soil. A dirty
filter will reduce the dehumidifier’s
capacity and efficiency. Do not wash
the filter. Replace the filter when it has
been used on a mold remediation job and
when it shows signs or normal wear and
tear.
Coil Cleaning: As the coils accumulate
soil, their heat transferring properties are
reduced. This can diminish water
extraction and create undue pressure on
the refrigeration system.
The coils should be cleaned about every
8 to 12 weeks. If the Atlantic LGR
Dehumidifier is used in a dusty
environment, cleaning may need to be
accomplished more frequently. The
coils should be dry before the following
cleaning operation is performed.
Dry Method. Inject compressed air
through each coil. After removing the
dry particle contamination, a wet
cleaning process may be used.
Caution!
Do not use a hose to flush the coils
and do not permit water to leak
into the electrical compartment.
Wet method. Use a soft brush and soapy
water. If soils have been allowed to
accumulate over time, they may be dry
and hard. Soak time may be required to
dissolve and release these soils from the
coils. A spray bottle or a syringe can be
used to apply controlled amounts of
cleaning solution. After cleaning, make
sure that the drain port, the condensate
tray and drain tubing are free of any
residual soil.
Electrical Wiring & Cord: Inspect the
power cord periodically to make sure
that the insulation is in good condition.
Replace worn or damaged cords.
Remove the dehumidifier cover to
expose the wiring and components.
Inspect wires to assure that they are
secured away from the fan blade.
Repair or replace as needed.
Fan Motor: Carefully remove dust and
debris from the fan motor and blade
assembly whenever you remove the
unit’s cover for interior cleaning.
Drain Hose: Inspect the gravity drain
hose to make sure it is in good condition.
The hose should be checked before your
Atlantic LGR Dehumidifier leaves the
shop and again before the unit is left on
the job.

Make sure that the drain hose is not
kinked or cracked. Avoid leaving the
drain hose in a folded position during
transport and storage.
Drip Tray: Inspect the drip tray.
Clean when dirt and debris are present.
Dirt and debris could clog the funnel
preventing water from draining.
Automatic Pump and Compressor:
Pump and compressor should be
inspected annually.
FEATURES
Rapid Hot Gas Defrost: Swiftly melts
ice formation on the cooling coil and
returns the unit to dehumidification
mode. This occurs in a fraction of the
time compared to a simple fan-defrost
system that can sacrifice more than 25%
of dehumidification operation time.
Compact Design: The overall width of
the unit is four inches (16%) narrower
than competitive units. This is achieved
by the inset wheels, which makes it more
maneuverable, especially through
narrow entryways and staircases.
Removable Heat Exchanger:
Allows for quick, easy cleaning and
maintenance which allows access to the
cooling coil surfaces.
Rugged ABS Skid Panel: Panel makes
loading and unloading simple and
protects the unit from scratches and
abrasions.
Control Panel: The control panel plus
the power and drain hose connections
are nested into the back panel for added
protection and convenience. It features
an hour meter, light indicators to let you
know if the unit is on, in defrost mode, if
pump is engaged or if there is an error.
Hinged Top: Unlike competitive units,
the hinged top prevents loss or
misplacement of the cover. The
detachable power cord and drain hose
store easily inside the hinged top thus
eliminating dangling cords and hoses.
