DV070 Ventilating
Dehumidier
Installation and Operation Manual
The Clean Comfort™ DV070 dehumidier
performs mulple funcons in a compact
enclosure: high-capacity dehumidicaon,
fresh air venlaon, and parculate ltraon.
Dehumidication
The highly ecient DV070 dehumidier
ulizes refrigeraon to cool the incoming
air stream below its dew point. This cooled
and drier air is then reheated by passing it
over the condenser coil.
Fresh Air Ventilation (optional)
Fresh outdoor air may be ducted to the
dehumidier. This provides fresh air to dilute
indoor pollutants and replenish oxygen
content in the building. The amount of fresh
air venlaon can be regulated by a variety
of dampers and controls in order to provide
desired venlaon rates.
Air Filtration
The DV070 features air ltraon, using a
MERV-11 media lter, to improve indoor
air quality. Clean Comfort DV070

INSTALLATION CONSIDERATIONS
IO-DV070 IO-DV070
Installation Considerations
• This equipment is designed to be installed INDOORS
IN A SPACE THAT IS PROTECTED FROM RAIN AND
FLOODING.
• Install the unit with enough space to access one of
the side panels for maintenance and service.
• Avoid direcng the discharge air at people, or over the
water in pool areas.
• If used near a pool or spa; be certain there is NO
chance the unit could fall into the water, splashed
and that it is plugged into a GFCI (GROUND FAULT
CIRCUIT INTERRUPT) OUTLET.
• DO NOT use the unit as a bench or table.
• DO NOT place the unit directly on structural members.
• A drain pan MUST be placed under the unit if installed
above a living area or above an area where water leak-
age could cause damage.
• Locate the unit near the exisng HVAC system to mini-
mize the required ductwork for connecng it to the
exisng air handling system. The controls for the dehu-
midier are remote from the unit and must be located
in the space that is to be condioned. The controls are
low voltage (24 VAC) and should be connected to the
unit with low voltage thermostat cable.
• If fresh air venlaon is desired, thought should be
given to the locaon for the fresh air ducng. A 6"
round insulated duct will have to be aached to the
8" supply duct of the unit and run to the outside of
the home to bring in fresh air. Use an 8" insulated
round duct for lengths of more than 50 feet or if
more than 100 CFM is needed. Consult local codes
for necessary distances from exhaust ports when
installing fresh air return.
Power Accessibility
Unit should be located in an area where the cord's length
(9') can easily reach a 115VAC electrical outlet with a
minimum of a 15 A circuit capacity.
Space
Locaon should have enough clearance to handle the
unit's overall dimensions as well as the necessary
return/supply ductwork to the unit. Allow a minimum
12" clearance to the side of the unit to allow for lter
removal and replacement.
Low Voltage Wiring
Unit locaon should be in an area where eld wiring the
remote controls (low voltage) to the unit will be possible.
Back-Draft Damper
It is recommended that a backdra damper be used in
the supply duct of the DV070, especially when connecng
to the supply ducng system. The backdra damper
prevents supply air from counter owing through the
DV070 when it is not operang. The unit locaon should
be chosen to allow installaon of this accessory if
requested by the end user.
Support Structure and Suspension
Place the DV070 on supports to raise the base of the
unit 2.5” above the drain pan beneath it. Do not place
the DV070 directly on structural building members with-
out vibraon absorbers or unwanted noise may result.
The DV070 may be suspended with steel hanger straps
(plumbers tape) or a suitable alternave from structural
members, as long as the suspending assembly supports
the DV070's base in its enrety. Do not hang the DV070
from its cabinet. Remember to place a drain pan under
the unit if it is suspended above a nished area or above
an area where water leakage could cause damage.
Electrical Requirements
iCAUTION!
Do not allow the 24V Terminal from DV070 to contact
the COM or DMPR Terminals from the DV070 or the
transformer will be destroyed.
The Clean Comfort DV070 dehumidier plugs into a
common grounded 115VAC outlet. The device draws
5.1 Amps under normal operang condions. If used
in a wet area (or a basement prone to ooding), a
ground fault circuit interrupter (GFCI) protected circuit
is required. Please, consult local electrical codes for any
further informaon.

CONDENSATE REMOVAL
IO-DV070 IO-DV070
The DV070 can be controlled by a variety of devices
including the Clean Comfort DVP-4034748 or DVP-4034753
digital controls. The controls are to be located remotely
from the unit and located in the space to be condioned.
The controls are low voltage (24 VAC) and should be
connected to the DV070 with low voltage wire
(thermostat or other appropriate).
Install the digital control in a central area of the home
where it will sense the relave humidity accurately.
iCAUTION!
Do not install the control where it may not accurately
sense the relave humidity such as near HVAC supply
registers, exterior doors, windows, water sources, or
on an outside wall.
The installer must supply the wiring between the
DV070 and the control. Be sure to safely route the
control wiring to prevent damage during installaon.
iCAUTION!
Do not cross wires when connecng the DV070 and
the control or damage to the transformer may result.
The remote controls of the DV070 are powered by a
low voltage circuit (24VAC) and must NEVER contact
or be connected to a high voltage circuit.
The screw terminals on the DV070 and the control
are labeled to prevent confusion.
Some of the screw terminals on the DV070 may not
be used with certain control and should be le
unconnected. Be sure to consult the electrical
schemac in this manual or inside the access panel
of the DV070 before making control connecons.
Condensate (Water) Removal
The Clean Comfort DV070 dehumidier generates
condensate. Condensate drains by gravity via the drain
port. Install a 3/4" male NPT adapter to the drain pan.
It is necessary to assemble your own drain pipe assembly
ulizing 3/4" PVC pipe to route the condensate to a drain.
Pitch/grade of drain should be 1" per 10'.
Take care when installing drain pipe to drain port of the
DV070; Use an adjustable wrench to secure the drain port.
When installing the drain hose make sure the feet are
extended such that the dehumidier is 2 1/2" o the
ground. Then coil the drain hose under itself or posion
a spacer to li the hose 1" o the ground aer the hose
has touched the ground. This procedure will create a
trap that ensures your unit drains correctly. See the
diagram below for further visual claricaon.
iCAUTION!
A trap in the drain line is required for the unit to drain
properly. Local codes may require a trap. Use care to
keep the pipe assembly as at to the oor as possible.
Kinks and/or humps will prevent proper drainage.
Lifting Condensate
An oponal condensate pump may be installed if a
vercal li is required to dispose of the condensate.
The condensate pump can be ordered direct from
your dealer.
Condensate Pump Installation (optional)
A condensate pump can be installed on the condensate
drain line of the Clean Comfort DV070 dehumidier if
vercal li is required to dispose of the condensate.
Condensate is automacally pumped to a remote locaon
when the water level in the condensate pump's reservoir
rises to close the automac oat switch. In the event
the pump fails and water rises too high in the reservoir a
Safety Float Switch will become open. The leads from this

switch should be installed in series with the 24V or DEHU
terminals to prevent the pump from overowing. If the
24V Terminal wire is in series with the Safety Float Switch
the DV70 and the dehumidier will shut o. If the DEHU
Terminal is in series with the Safety Float Switch the
compressor will turn o but the DV070 will connue to
venlate or circulate air as normal. Contact your local
electrician to install the Safety Float Switch directly to
the dehumidier.
For installaon guidelines, refer to the "Condensate
Pump Installaon" secon at the back of this manual.
Ducting
Installing Duct Collars
The DV070 comes supplied with an 8" round inlet collar
and an 8" round exhaust collar. Follow instrucons
included with these collars.
Ducting for Dehumidication
For the ideal installaon, draw air from the central part
of the home and return it to the isolated areas of the
home like the bedrooms, den, ulity room, or family
room. Be sure to ulize as many of these remote rooms
as possible and not just one locaon. The ductwork of
the exisng HVAC system can be used to supply air to
the home. If the exisng supply goes to isolated areas of
the home, discharge the supply from the DV070 into the
supply duct of the exisng HVAC system. If the exisng
heang system incorporates a central supply, installa-
on of a separate supply duct from the DV070 to each
isolated area is recommended.
Fresh Air / Supply Air
iCAUTION!
DO NOT draw air directly from the kitchen, laundry, or
isolated basement. You may draw air from a basement
that is open to the home. All exible ducng connected
to the DV070 should be UL listed.
A short piece of exible ducng on ALL DV070 duct
connecons is recommended to reduce noise and
vibraon transmied to rigid ductwork in the structure.
Ducng the DV070 requires consideraon of the
following points:
Duct Sizing: For total duct lengths up to 25', use a
minimum 8" diameter round or equivalent rectangular
duct. For longer lengths, use a minimum 10" diameter
or equivalent duct. Grilles or diusers on the duct ends
must not excessively restrict airow.
Isolated Areas: Eecve dehumidicaon may require
that ducng be branched to isolated, stagnant air ow
areas. Use 8" or larger diameter branch ducng to each
of two or three areas, use 6" or larger to each of four or
more areas. Provisions must be made to provide airow
from supply locaons to central return locaon. Proper
air distribuon is important to ensure even humidity
control and heat distribuon throughout the home.
Connecting to Existing HVAC Systems
An oponal 8" gravity backdra damper is available to
prevent reverse air ow through the DV070. If the DV070
is ducted to the supply of an air handler, the backdra
damper should be placed in the DV070 supply duct.
Venlaon operaon is controlled by the digital control
oered with the DV070. These controls determine the
me/frequency that the unit introduces outside air into
the HVAC system. The amount of outside air can be
restricted by the blade damper in the 6" collar. Some
control opons require a 6" motorized damper be
installed in the 6" fresh air duct.
iCAUTION!
Do not connect with a stac pressure greater than or
equal to +.5 WG. Contact Technical Support at
1-855-239-2665 for addional details.
Ducting for Fresh Air (Optional)
Fresh air may be brought into the home by connecng an
insulated duct from outside the home to a tee connected
to the 8" duct that brings the return air from the home
to the DV070. Venlaon is acvated by turning on the
fan switch or acvang the humidity control. Acvate
the venlaon mer on units with the venlang and
humidity control DVP-4034748 to bring in fresh air. Refer
to the Controls secon of this manual for programming
instrucons of the venlaon mer.
Advantages of this form of venlaon include:
1. Outside air is ltered before entering the building.
2. Outside air will be dehumidied before entering
if the DV070 is running in dehumidicaon mode.
3. Drawing air from outside and blowing inside aids in
slightly pressurizing the home. This helps prevent
dirty and humid air from entering the home else-
where. It also reduces the potenal for carcinogenic
radon gas to enter and provides a small amount of
make-up air for atmospheric combuson and exhaust
devices such as a clothes dryer, replace, furnace or
water heater.
4. Exhaust fans are recommended in the bath rooms
and kitchen.

DUCTING
IO-DV070 IO-DV070
In cold climates or areas where the outdoor dew point is
low at mes, venlaon can be used to dehumidify the
home, making the DV070 capable of year-round drying.
This is accomplished by bringing the dry, low dew point air
into the home during these mes. This approach is oen
more economical than running the dehumidier to remove
excess moisture from the home.
In cold climates, it is crical to adequately venlate to
reduce the indoor humidity to avoid moisture accumulat-
ing in the wall cavies. For example; in a house that
experiences condensaon on the interior surface of the
windows during the winter, increasing the amount of
venlaon will oen cure the problem.
An insulated 6" diameter duct is generally sucient to
provide up to 55 CFM of outside air. Large quanes of
outside air can impact the DV070's performance posively
or negavely, depending upon the inside and outside air
condions.
The outside air duct should be connected to the 8" duct
connected to the front of the DV070. The amount of outside
air can be restricted by the blade damper in the 6" duct.
Fresh Air Ventilation
Venlaon controls determine the me/frequency that the
DV070 introduces outside air into the home. The amount/
frequency of venlaon should be based on the size and
occupancy of the residence. If you are unsure of your
venlaon air requirements or have need for higher air
ows, consult Technical Support by calling 1-855-239-2665.
Installation in a Basement or Crawlspace with
an Existing Forced-Air HVAC System
It is recommended that a new, separate return duct be
installed for the DV070 from a central area of the house.
If this is not possible, and if the exisng system has
mulple returns, select one to disconnect from the
exisng forced-air system and use it for the dedicated
DV070 return. Always select a return from a central
locaon in the home in an area that is always open to the
rest of the home. Do not use a return from a room that
may have its door closed much of the me. If the home in
which the DV070 is to be installed has an exisng forced
air HVAC system, ulize the HVAC system to make the
DV070 installaon easier.
Basement Installation: Install a separate 8" return to
the DV070 in a central area of the home. Oponal: Duct
the supply from the DV070 to an 8" x 8" x 8" tee/damper,
adjusted to 20% open to the basement. This allows the
ability to discharge a variable amount of dehumidied
air into a basement that may not be well served by the
exisng duct system, especially during the summer
months. Duct the other side of the tee to the air supply
of the exisng HVAC system. A backdra damper is
required in the duct between the 8" tee and the central
supply duct to prevent air from being discharged into
the basement during central fan operaon. Connect an
insulated duct from outside to the 8" return duct of the
DV070 if you wish to provide venlaon air. See Figure 4.
Crawlspace Installation: Install a separate return
to the DV070 in a central area of the home. Oponal:
Duct the supply from the DV070 to an 8" x 8" x 8" tee/
damper that is 20% open to the crawlspace if desired.
Duct the other side of the tee to the air supply of the
exisng HVAC system with a backdra damper. Connect
an insulated duct from outside to the 8" return duct of
the DV070 if you wish to provide oponal venlaon
air. See Figure 4.
Installation in an Attic with an Existing
Forced-Air HVAC System
iCAUTION!
ALWAYS install a catch pan with a drain or Safety
Float Switch for condensate under the DV070
in an ac installaon or condensate may damage
the living space below.
The Safety Float Switch should be installed in series
with the eld wire that connects the DEHU terminal
from the DV070 to the blue (#5) lead on the digital
control. If overow occurs, this switch opens the
compressor control circuit and stops water producon
before the catch pan overows. The DV070 will
connue to venlate or circulate air as normal,
but will not dehumidify unl this switch closes.

Step 4. Secure the exhaust panel to the base by
replacing the six (6) screws.
The preferred method of installaon is to create a
separate return to the DV070 in a central area of the
home. Duct the supply from the DV070 to the air
supply of the exisng HVAC system. Connect an
insulated duct from outside to the 8" return duct
of the DV070 if you wish to provide fresh make-up air.
Adjust a damper in the duct to provide the desired
air ow. Using the digital control, program the unit
to bring in the desired amount of fresh air.
Step 1. Using T-20 Torx Driver, remove three (3)
sheet metal screws that aach the exhaust panel
from each side of the DV070 Dehumidier. There will
be a total of six (6) screws. Do not remove the
exhaust collar.
Step 2. Remove the exhaust panel.
Step 3. Rotate the exhaust panel so that the exhaust
collar is located on the top of the unit. Align screw
holes and snap the panel onto the base.

Installation in a Home with No Existing
Forced-Air HVAC System
When installing the DV070 in a home that does not have
a forced-air HVAC system, a single return to the DV070
should be installed in central open area of the home.
DO NOT locate the return in a bathroom or a kitchen.
The supplies of the DV070 should be located in the
remote areas of the home such as bedrooms, den, etc.
Be sure to ulize as many of these remote rooms as
possible and not just one locaon. By ducng this way,
the air inside the enre home will circulate through the
DV070 to be ltered and dehumidied. Avoid discharging
all the air from the dehumidier in one locaon to prevent
heat buildup in that area. 6" diameter duct is recom-
mended for branches to the bedrooms, 8" diameter duct
is recommended for branches to larger areas. Connect an
insulated duct from outside to the 8" return duct of the
DV070 if you wish to provide venlaon.
Ducting for High-Eciency Filtration
The lter included with the DV070 is a very ecient
MERV 11 media lter. This lter should be checked
every three months and changed every 6-12 months.
Converting to Vertical Discharge Airow
The DV070 Dehumidier is shipped from the factory
with the exhaust panel of the cabinet congured for
horizontal air discharge. The cabinet can be easily
converted to vercal air discharge. To convert the air
discharge from horizontal to vercal, follow these steps:

Quiet Installation
Consider compression vibraon and airow noise during
installaon. Use of ex duct and/or vibraon isolaon
materials during mounng and ducng will result in
quieter operaon. A length of exible ducng on all
DV070 duct connecons is recommended to reduce
noise and vibraon transmied to rigid ductwork
in the home.
Controls
The DV070 Dehumidier 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 Dehumidier 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 Dehumidier 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 mounng locaon for the digital control
is not close to the area where humidity control is needed,
use DVP-4034753 digital control which has the same
funconality as the DVP-4034748, but uses a separate,
wired sensor for monitoring humidity levels remote from
the user interface of the control.
iCAUTION!
When using a remote wired dehumidistat, be sure the
built-in dehumidistat is set to the OFF POSITION by
turning it counter clockwise unl it stops. Failure to do
so may cause the unit to sense the humidity from
the wrong area.
In addion to the built-in dehumidistat, the DV070
can be equipped with various accessories to control its
operaon. The Clean Comfort DVP-4034748 digital
control is recommended. The DVP-4034748 allows
homeowners the ability to monitor and control relave
humidity levels in their home as well as provide proper

remote sensing opon (part number DVP-4034753) for
installaons where the preferred locaon for mounng
the digital control is not close to the area where humidity
control is needed.
iWARNING!
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 ve, 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 dehumidier.

Service
iWARNING!
Servicing the DV070 Dehumidier with its high pressure
refrigerant system and high voltage circuitry presents
a health hazard which could result in death, serious
bodily injury, and/or property damage. Call your HVAC
contractor for servicing or repair of this equipment.
Technical Description of
Dehumidier Operation
The DV070 uses a refrigeraon system similar to an air
condioner's to remove heat and moisture from incom-
ing air, and add heat to the supply air that is discharged
from the dehumidier. Hot, high-pressure refrigerant
gas is routed from the compressor to the condenser coil.
The refrigerant is cooled and condensed by giving up its
heat to the supply air being discharged from the unit.
The refrigerant liquid then passes through a strainer and
Warranty
A consumer warranty cercaon is included at the
end of the manual. Please read it before any repair is
iniated. If a warranty repair is required, call the install-
ing contractor or the factory at 1-855-239-2665 for
warranty claim authorizaon and technical assistance.
capillary tubing which causes the refrigerant pressure
and temperature to drop. It next enters the evaporator
coil where it absorbs heat from the incoming air and
evaporates. The evaporator operates in a ooded condi-
on, which means that all the evaporator tubes contain
liquid refrigerant during normal operaon. A ooded
evaporator should maintain nearly constant pressure and
temperature across the enre coil, from inlet to outlet.
The mixture of gas and liquid refrigerant enters the
accumulator aer leaving the evaporator coil.
The accumulator prevents any liquid refrigerant from
reaching the compressor. The compressor evacuates
the cool refrigerant gas from the accumulator and
compresses it to a high pressure and temperature.

OPERATION
IO-DV070 IO-DV070
iWARNING!
ELECTRICAL SHOCK HAZARD: Electrical power must be
present to perform some tests. These tests should be
performed by a qualied service person.
Remote Controls
The DV070 dehumidier is controlled by digital controls
that are remote from the unit. You may or may not have
the devices listed below depending on the model of the
control you purchased. If the dehumidier fails to oper-
ate as desired, always check the sengs of the controls
to insure that they are correct. Check that the controls
are receiving 24VAC from the dehumidier. Check the
connecons between the dehumidier, the control,
and the eld control wiring.
Humidity Control
The humidity control is an adjustable switch that closes
when the relave humidity of the air in which it is
located rises to the screen set point. The Clean Comfort
DV Series dehumidier is equipped with an automac
defrost mechanism. If the dehumidier operates in
condions that develop frost on the evaporator, it will
sense the frost build-up and automacally defrost the
evaporator. The dehumidier may not appear to be
operang correctly during the defrost sequence, but
once the defrost sequence is completed, the unit will
resume dehumidifying.
Programmable Ventilation Timer –
DVP-4034748 / DVP-4034753
The venlaon mer controls the impeller fan and the
motorized fresh air damper. When the venlaon mer
is acvated, the dehumidier will circulate the indoor
air, and bring in fresh air from outside. The venlaon
mer should be set for the required venlaon of the
residence. The home should be venlated with fresh air
as suggested by applicable codes and standards. If the
dehumidier fails to venlate as expected, check that the
me on the mer is correct. Also check the programs on
the mer to be sure that the mer is calling for venla-
on at the correct mes.
iWARNING!
ELECTRICAL SHOCK HAZARD: Electrical power must be
present to perform some tests. These tests should be
performed by a qualied service person.
Unit Test to Determine Problem:
1. Detach eld control wiring connecons from
main unit.
2. Connect the 24V and fan terminals from the main unit
together; only the fan should run. Disconnect
the terminals.
3. Connect the 24V and DEHU terminals from the main
unit together or turn the built-in dehumidistat all
the way clockwise to the "ON" posion; the
compressor and fan should run.
4. If these tests work, the main unit is working properly.
You should check the digital control panel and eld
control wiring for problems next.
5. Remove the digital control panel from the mounng
box and detach it from the eld installed control
wiring. Connect the blue, yellow, and green wires
from the control panel directly to the corresponding
DEHU, 24V, and fan terminals on the main unit. Leave
the COM and DMPR terminals disconnected!
6. Engage the fan switch on the control; the fan
should run. Turn o the fan switch.
7. Engage the dehumidistat of the control; the
compressor and fan should run.
8. If these tests work, the problem is most likely in
the eld control wiring.
NOTE: Refrigeration systems should ONLY
be serviced by a qualied service technician.
If you need additional information, consult
Technical Support at 1-855-239-2665.
Refrigerant Charging
If the refrigerant charge is lost due to service or a leak,
a new charge must be accurately weighed in. If any
of the old charge is le in the system, it must be
recovered before weighing in the new charge. Refer to
the unit nameplate for the correct charge weight and
refrigerant type.
