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 ad-
justable 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. NO-
TICE: 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 con-
densate water intermittently, in a steady stream, or not at all for
short periods of time. These functions indicate normal dehumi-
difier 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 (purchased separately). Properly installed, ducting can
help circulate the air in the drying environment and improve
drying efficiency. When using ducting, fasten it securely to the
duct ring (see Figure 3). Place the open end of the duct some
distance away from the unit. Use 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 airflow might be obstructed. 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 output can be set up
to exhaust dry air from the end of the unit or from the side of
the unit. See Fig. 1.

To change the airflow configuration, first unplug the CMC, then
remove the four screws that hold each panel in place (see
Figs. 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 recom-
mends 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.
