INTRODUCTION
Dri-Eaz dehumidifiers reduce humidity in enclosed
structural environments by removing water vapor from
the air. With proper use, your dehumidifier can help dry
carpet, carpet pad, floors, walls, building contents and
more. Using Dri-Eaz dehumidifiers can also help prevent
secondary damage caused by high humidity. For best
results, use your dehumidifiers with Dri-Eaz TurboDryer
airmovers placed around the perimeter of the room to
distribute heat energy and release moisture from wet
surfaces into the air.
How LGR dehumidifiers work
Dri-Eaz low-grain refrigerant dehumidifiers operate by
pulling moist air in across a very cold evaporator core.
The moisture in the air condenses on the coil. In certain
conditions, the machine operates in defrost mode,
warming any frost that has accumulated on the
evaporator coil back into water. The water collects in a
tray and is pumped out through a hose. Onboard
sensors continually monitor environmental conditions
and system operations of the dehumidifier, including
temperature and relative humidity, which can be viewed
on the display panel. The unit also transmits data to a
HygroTrac gateway, which can store the information or
relay it to the HygroTrac website (see below).
LGR (Low Grain Refrigerant) dehumidifiers have better
heat exchange and defrost abilities than regular
refrigerant dehumidifiers, and are able to continue
removing moisture in drier environments.
HygroTrac remote sensing
The LGR "i-Series" dehumidifiers are equipped with
HygroTrac wireless sensor technology. When used with
the HygroTrac Remote Monitoring system, this
07-01674G 2013-01 Warranty 07-00420
technology allows the user to monitor site conditions and
equipment performance in real time via the internet.
Here's how it works. The dehumidifier transmits humidity
and temperature values to a gateway placed at the
jobsite. The gateway can be configured to store this data
for later retrieval, or to transmit the data via an Internet
connection to a secure website. Users may log on to the
HygroTrac website from any computer with internet
access and view, print and download a wide variety of
customizable reports, charts and graphs.
Used in conjunction with additional sensors placed in the
drying environment, the HygroTrac system provides an
extremely accurate view of the drying environment,
equipment performance and drying progress. The
system can also be set to alert you via email or text
message on your cell phone if inlet or outlet conditions of
the dehumidifier exceed certain parameters you have set
on the HygroTrac website.
If the HygroTrac system reports a Power Off status for a
unit on a job site, you will know immediately that the unit
has been turned off or that the power has otherwise
been interrupted. HygroTrac can be configured to
automatically notify you by e-mail or text message if this
occurs.
Asset tracking
When the unit is disconnected from AC power, the
system will automatically go into in a "Standby" mode,
periodically transmitting a Standby signal. Two
replaceable AA batteries provide the power for this mode
of operation (see "Installing the Sensor Batteries," p. 1).
The Standby signal can be used to confirm the location
and status of your unit. A HygroTrac gateway placed in
your storage area, for example, will receive Standby
transmission from any 2800i and 3500i units in the
vicinity and report this status to your HygroTrac website.
Data transmitted
The information collected by the system includes the
temperature and relative humidity of the inlet and outlet.
The HygroTrac system uses this data to calculate grain
depression (the amount of moisture being removed from
the air) and other important information about the unit's
operating status. The system also transmits all top level
status messages. For more information, see "System
status and data messages," p. 9.

POSITIONING A DEHUMIDIFIER
For best results, operate your dehumidifiers in an
enclosed area, as this creates a drying chamber. Close
all doors and windows that open to the outside to
maximize the unit's water removal efficiency. Also, keep
