Quiet Installation
Consider compression vibration and airflow noise during
installation. Use of flex duct and/or vibration isolation
materials during mounting and ducting will result in
quieter operation. A length of flexible ducting on all
DV070 duct connections is recommended to reduce
noise and vibration transmitted to rigid ductwork
in the home.
Controls
The DV070 Dehumidifier features a built-in dehumidistat
control as well as the ability to wire a remote mounted
control to the unit. The control used to operate the
unit should be located in an area where the control can
accurately sense the humidity of the area where humidity
control is desired.
If the DV070 Dehumidifier is located in the area where
humidity control is desired, consider using the built-in
control. Adjust the humidity control so that the unit
maintains the desired level of humidity.
If the DV070 Dehumidifier is located outside of the area
where humidity control is desired, consider using a re-
motely mounted digital control, such as the DVP-4034748,
located in the area where humidity control is desired.
If the preferred mounting location for the digital control
is not close to the area where humidity control is needed,
use DVP-4034753 digital control which has the same
functionality as the DVP-4034748, but uses a separate,
wired sensor for monitoring humidity levels remote from
the user interface of the control.

CAUTION!
When using a remote wired dehumidistat, be sure the
built-in dehumidistat is set to the OFF POSITION by
turning it counter clockwise until it stops. Failure to do
so may cause the unit to sense the humidity from
the wrong area.
In addition to the built-in dehumidistat, the DV070
can be equipped with various accessories to control its
operation. The Clean Comfort DVP-4034748 digital
control is recommended. The DVP-4034748 allows
homeowners the ability to monitor and control relative
humidity levels in their home as well as provide proper
ventilation. This digital control is also offered with a
remote sensing option (part number DVP-4034753) for
installations where the preferred location for mounting
the digital control is not close to the area where humidity
control is needed.

WARNING!
DO NOT allow the 24V terminal from the unit to contact
the COM/DMPR terminals from the unit or damage
to the transformers will result.
The DV070 is controlled using five, labeled screw terminals:
FAN
= Fan control
DEHU
= Dehumidification (fan and compressor) control
COM
= 24VAC power transformer neutral side
(common with DMPR Terminal)
DMPR
= 24VAC power transformer neutral side
(common with COM Terminal)
24V
= transformer high side
A 40VA transformer is wired between the COM/DMPR
terminal and the 24V terminal of the DV070. This low
voltage power source powers the relay coils which
control the fan and compressor. This 24VAC transformer
can also be used to power HVAC accessories external to
the dehumidifier.
• To turn the dehumidifier ON make contact between
24V and DEHU terminals.
• To turn the fan ON make contact between 24V and fan
terminals.
• To power an HVAC accessory, connect the accessory
to the DMPR (or COM) terminal and the 24V terminal.
i
CAUTION!
If an optional damper is not used, do not connect the
DMPR terminal to the DVP-4034748 control or damage
to the transformer may result.
