Important Precautions
• The device is designed to be installed indoors in a space that is protected from rain and ooding.
• Install the unit with enough space to access all sides for maintenance and service. The entire shell needs to be
removed in order to do repairs.
• Avoid directing the discharge air at people. The dehumidier should be used in the upright position.
• If used near a water source; be certain there is no chance the unit could fall into the water or get splashed and
that it is plugged into a dedicated circuit and Ground Fault Circuit Interrupter (GFCI) protected outlet.
• DO NOT use the dehumidier as a bench or table.
• DO NOT place the dehumidier directly on structural building members without vibration absorbers or unwanted
noise may result. Place the EDHUM070H on supports to raise the base of the unit.
• A drain pan with a oat switch MUST be placed under the dehumidier if installed above a living area or above
an area where water leakage could cause damage.
Location Considerations
• Allow sucient clearance to handle the unit’s overall dimensions as well as the necessary return and supply
ductwork to the unit.
• Allow sucient clearance for lter removal and to prevent airow obstruction.
• Electrical service access will require the removal of the outside shell. Allow sucient clearance around the unit.
• Locate the dehumidier in an area where the cord’s lenght (9') easily reaches a 115 VAC electrical outlet with a
minimum of a 15 Amp circuit capacity.
• Locate the dehumidier in an area where eld wiring the control (low voltage) to the unit will be possible.
• It is recommended that a
backdraft damper be used in
the discharge duct of the
EDHUM070H, especially when
connecting to the supply
ducting system. The backdraft
damper prevents supply air
from counter owing through
the EDHUM070H when it is not
operating. The dehumidier’s
location should be chosen to
allow installation of this
accessory if necessary.
• The EDHUM070H may be
suspended with the hang kit
or a suitable alternative from
structural members,
ensuring the assembly
supports the dehumidier’s
base in its entirety. DO NOT
hang the EDHUM070H from
its’ cabinet.
• Allow for proper drainage and
routing of needed drain pipes.

8Installation & Operation Instructions
The EDHUM070H generates condensate.
Place a secondary drain pan with a oat switch under the dehumidier if it is suspended above a nished
area or above an area where water leakage could cause damage.
A drain trap is required for the dehumidier to run properly. Install a 3/4" threaded male NPT adapter to the
drain pan. Install a drain pipe assembly utilizing 3/4" PVC pipe to transport the condensate to a drain. Pitch
of drain should be 1" per 10'.
An optional condensate pump kit is available for use with the EDHUM070H and may be installed if lift is
required to dispose of condensate. Condensate is automatically pumped to a remote location when the
water level in the pump’s reservoir rises to close the oat switch.
The pump also contains a safety oat switch. The white leads from this switch extend from beneath the
pump cover. This switch should be installed in series with the eld wire that connects to the common lead
from the EDHUM070H to the control panel. If the pump fails, this switch opens the common control circuit
and stops water production before the reservoir overows. Contact a qualied electrician to install the safety
oat switch to the EDHUM070H dehumidier.
Note: An optional condensate pump kit can be purchased from a local dealer or online.

The recommended installation creates a separate return for the EDHUM070H in a central area of the
structure. Duct the supply of the unit to the air supply of the existing HVAC system. Connect an insulated
duct from outside to provide fresh make-up air (optional).
DUCTING TO HVAC SYSTEMS
CAUTION!CAUTION!
DO NOT CONNECT WITH A STATIC PRESSURE GREATER THAN OR EQUAL TO +0.5 WG.
CONTACT TECHNICAL SUPPORT AT [phone] FOR ADDITIONAL DETAILS.
Ducting Considerations:
• All exible ducting connected to the EDHUM070H should be UL listed.
• A short piece of exible ducting on all EDHUM070H duct connections is recommended to reduce noise
and vibration transmitted to rigid ductwork in the structure.
• Use a minimum 8" diameter round or equivalent rectangular duct for total duct lengths of up to 25'. Use a
minimum 10" diameter or equivalent for longer lengths.
• Grills or diusers on the duct ends must not excessively restrict airow.
• A length of 8" or more of insulated ex duct or any other vibration isolating material on the outlet of the
EDHUM070H will reduce air noise from the blower.
• Eective dehumidication may require that ducting be branched to isolated, stagnant air ow areas. When
ducting to two or three areas, use 6" or larger diameter branch ducting. When ducting to four or more
areas, use 4"-6" or larger diameter branch ducting. Provisions must be made to provide airow from
supply locations to the central return location. Proper air distribution is important to ensure even humidity
control and heat distribution throughout the structure.
• DO NOT locate the return in a bathroom or a kitchen.

10 Installation & Operation Instructions
Recommended HVAC System Installation
DUCTING TO HVAC SYSTEMS
The recommended installation draws air from a dedicated indoor air return and ducts the supply of the
dehumidier to the air supply of the existing HVAC system. Utilize the optional fresh air ventilation duct to
provide outside air.
• Install a dedicated 8" air return for the EDHUM070H from a central area of the structure.
• Duct the supply of the EDHUM070H to the supply of the existing HVAC system with a backdraft damper.
• If the existing system has multiple returns, instead of installing a dedicated return to the EDHUM070H,
it is possible to select one to disconnect from the existing HVAC system and use it for the dedicated
EDHUM070H return. Select a return from a central location in the house that is always open to the rest
of the structure. DO NOT use a return from a room where doors are kept closed.
• DO NOT locate return in a bathroom or kitchen.
• Control should be located remotely from the dehumidier and placed in a central location.

Fresh air ventilation is optional.
Fresh air may be brought into the structure by connecting an insulated duct from outside the structure to
a tee located in the inlet duct of the EDHUM070H. A ventilation control is needed to program the time and
frequency that the unit introduces outside air. The time and frequency of ventilation should be based on the
size and occupancy of the residence.
• The 6" fresh air ventilation duct should tee into the 8" round collar on the front of the EDHUM070H.
• An insulated 6" diameter duct can provide up to 55 CFM of outside air.
• Performance of the EDHUM070H can be impacted by inside and outside air conditions.
• When a 6" motorized damper is used, a digital control is required.
• It may be necessary to use 8" duct work if additional fresh air is required.
• In cold climates or at times when the dew point is low, ventilation can be used to dehumidify the
structure, making the EDHUM070H capable of year-round drying.

Option 1: Calculating Airflow Requirement Using ASHRAE 62.2-2016 Airflow Equation
ASHRAE Airow in CFM = [House Area in Sq.Ft. x 0.03] + [(Number of Bedrooms +1) x 7.5]
NOTE: Use ‘Number of Bedrooms + 1’ or ‘Number of Occupants’, whichever is larger.
Example 1: Number of Bedrooms + 1
1800 square foot house with 3 bedrooms, 4 occupants = [1800 X 0.03] + [(3+1) X 7.5] = 84 CFM
Example 2: Number of Occupants
1800 square foot house with 3 bedrooms, 5 occupants = [1800 X 0.03] + [5 X 7.5] = 91.5 CFM

A control can be used with the EDHUM070H. Santa Fe oers the DEH 3000 proprietary control. The DEH 3000
monitors and controls relative humidity and proper ventilation levels in their home. This control is also available
with a remote sensing option. The EDHUM070H features a built-in dehumidistat control as well as the ability to
wire a remote mounted control to the unit. If the EDHUM070H is located outside of the area where humidity
control is desired, consider using a remote wired humidity controller that is located in the area where humidity
control is desired. If using the built-in dehumidistat to control the unit, locate the control in an area where it can
accurately sense the humidity of the area where humidity control is desired. If the EDHUM070H 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.
Note: The DEH 3000 is sold seperately and can be purchased online or through your local dealer. Other
thermostats are compatible with the EDHUM070H.

Troubleshooting Procedure for Control
Related Issues
This method of diagnosis will test the 3 main
components of the control circuit individually to
indicate any potential problems. This is to be used
when the control will not activate the main unit.
1. Detach eld control wiring connections from
the terminals on the main unit.
2. Connect the 24V and FAN terminals
together; only the fan should run.
Disconnect the terminals.
3. Connect the 24V and DEHU terminals
together; fan and compressor should run.
Disconnect the terminals.
4. If this test works, the main unit is working
correctly from a control standpoint.
5. Reconnect eld control wiring to the terminals
on the main unit.
6. Remove the control panel cover and detach
the eld wiring from the control connections.
7. Connect the 24V and FAN terminals together;
only the fan should run. Disconnect the terminals.
8. Connect the 24V and DEHU terminals
together; fan and compressor should run.
Disconnect the terminals.
9. If this test works, then the eld control wiring
is ok.
10. If the problem persists, then the control is
most likely faulty.

Symptom Possible Reason Troubleshooting Procedure
Troubleshooting Procedure for Performance
Related Issues
This method of diagnosis is used to function
check the internal components in the dehumidi-
er. This is to be used when a performance issue
is suspected.
1. Set the humidity controller all the way to the
most humid setting or o position – Did the
unit shut o?
2. If yes, turn the fan setting to the ON position –
does the fan start?
3. If fan starts, leave in the fan ON position and
set the humidity all the way to driest setting.
May have to wait 5 minutes for the compressor
to start.
4. Listen for a distinct buzzing/humming sound
of a compressor starting up – do you hear this
noise?
5. If compressor is running and continues to run,
after about 15 minutes you should feel a slight
increase in air temperature being discharged
out of the discharge air side of the unit.
6. If so, depending on your environmental
conditions (temp/Rh%), you should see some
water production out of the hose within
30 minutes or so. (Note: If the room
temperature is 55 degrees or below and/or
in area of low relative humidity, the
dehumidier will produce little to no water.)
7. Collecting the water removed in a 24 hour period
will give a measurement of performance.

SERIOUS BODILY INJURY, AND/OR PROPERTY DAMAGE. SERVICE MUST BE PERFORMED BY
A QUALIFIED SERVICE TECHNICIAN.
If the refrigerant charge is lost due to service or a leak, the leak should be repaired and a new charge must
be accurately weighed in. If any of the old charge is left 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.
