INTRODUCTION
The CMC100 reduces humidity in enclosed structural
environments by removing water vapor from the air. With
proper use, the CMC100 can help to dry out damp structural
materials, insulation, and contents, and maintain a healthy
level of humidity. Using the CMC100 may also prevent
secondary damage caused by high humidity.
How the CMC100 works
The CMC100 refrigerant dehumidifier uses a fan to draw moist
air in and condenses it into water that collects in a tray and is
automatically pumped out through a drain hose. A humidistat
automatically shuts the unit off when the desired level of
humidity has been achieved.
Features:
•Industrial-quality dehumidifier removes up to 70 pints (33
liters) of water per day.
•Automatic humidistat control means set-and-forget
convenience.
•Ductable outlet for flexible application.
•Recessed handles for easy positioning in confined
spaces.
•Interchangeable intake and output panels allow for use is
a wide variety of settings.
•Quiet operation and low power consumption.
•The CMC100 has been awarded the ENERGY STAR
INSTALLATION
Location
The CMC100 works best in an enclosed area, as this creates a
drying chamber. Excessive infiltration of damp air will increase
operating time.
How to position the CMC100 dehumidifier
Place your CMC100 dehumidifier in the middle of the space,
away from walls, footings, ducts and other materials that may
prevent the free flow of air around and through the unit.

Keep unit level
The unit must be level to operate properly. Four screw-in
adjustable foot pads are provided. If the CMC is to be used on
an uneven surface, these feet must be assembled and
installed into the bottom of the CMC before placing the unit into
service.
1. To assemble the feet, press the bolt through the center of
the rubber foot and tighten the nut until it is snug against
the rubber foot.
2. To install the feet into the CMC100 base, screw one foot
assembly into the bottom of each corner of the unit.
NOTICE: To avoid damage to the condensate drain outlet,
do not tip the unit over onto the condensate drain side.
3. To level the unit with the feet, place a carpenter’s level on
the top of the unit and adjust the footpads to raise or lower
each corner of the unit until it is level.
NOTICE: The CMC100 must be kept in an upright position. If it
is necessary to place the unit on its side, such as during the
installation of the feet, return the unit to the upright position and
wait at least 10 minutes before starting the unit.
Drain hose set-up
During operation, water condenses out of the air and collects in
a drain pan inside the unit. The CMC100 automatically pumps
out this water through the drain hose outlet (see Figure 3).
Dri-Eaz recommends directing the hose into a drain or well
away from area to be kept dry.
NOTICE: Do not place the end of the drain hose higher than 3
feet (1 meter) above the top of the CMC, or leaking may occur.
Pump operation
Depending on operating conditions, the unit may produce
condensate water intermittently, in a steady stream, or not at
all for short periods of time. These functions indicate normal
dehumidifier and pump-purge operations.
NOTICE: To avoid spills, always secure the end of the drain
hose so that the intermittent pumping action doesn’t shift the
hose out of position.
NOTICE: Do not allow the outlet of the drain hose to become
submerged, blocked or otherwise subject to pressure that
might reduce the ability of unit to pump water.
Duct the outlet for optimum performance
The processed air outlet is designed to accept standard 6 inch
ducting (not included). For best results, use ducting and fasten
it securely to the duct ring (see Figure 3). Place the open end
of the duct some distance away from the unit. Ducting the
processed (outlet) air away from the unit will help to ensure
more complete distribution of dehumidified air throughout the
drying area. Install with insulated flex ducting for the quietest
operation.
OPTIONAL CONFIGURATIONS
The CMC100 features interchangeable panels that allow the
unit to be adapted for use on shelves, small storage areas or in
other locations where directing the air straight through the unit
is not possible. The damp air intake can be set up to draw in
air from the end of the unit or from the side of the unit.
Similarly, the dry air output can be set up to exhaust processed
air from the end of the unit or from the side of the unit. See
Figure 1, below.
To change the configuration, first unplug the CMC, then
remove the four screws that hold each panel in place (see
Figures 2 and 3). Lift the panels out of the CMC frame.
Replace the panels in the desired position and carefully tighten
the screws. NOTE: When placing both intake and output
panels on the side of the unit (option C, above right), Dri–Eaz
recommends attaching ducting to the output ring and placing
the open end of the ducting some distance away from the
CMC. This will help distribute the processed air more
completely.

OPERATION
1. Plug in the power cord into a standard 115V grounded
outlet. The unit must be operated on a 115V/60 Hz circuit
protected by a Ground Fault Interrupter (GFI) device.
2. Attach one end of the drain hose to the condensate drain
outlet and directing the other end into a drain or away from
area to be kept dry. NOTICE: To prevent CMC100 drain
pan overflow, ensure that there are no kinks or sharp
bends in the drain hose and do not place the outlet of the
hose higher than 3 ft. (1 m) above the top of the CMC100.
3. The CMC100 is controlled by an electronic touchpad
humidistat. The unit will automatically start when the
humidity of the surrounding air exceeds the humidity level
selected.
4. Set humidity set point with Control Panel (see below).
