1. Important Precautions
• The device is designed to be installed indoors in a space that is protected from rain and flooding.
• 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 Santa Fe Ultra120V on supports to raise the base of the unit.
• A drain pan with a float switch must be placed under the dehumidier if installed above a living area or above
an area where water leakage could cause damage.

2. Location Considerations
• Allow sufcient clearance to handle the unit’s overall dimensions as well as the necessary return and
supply ductwork to the unit.
• Allow sufcient clearance for lter removal and to prevent airflow obstruction.
• Electrical service access will require the removal of the front panel. Allow sufcient clearance on this side of
the unit.
• Locate the dehumidier in an area where the cord’s length (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 Santa Fe Ultra120V,
especially when connecting to the supply ducting system. The backdraft damper prevents supply air from
counter flowing through the Santa Fe Ultra120V when it is not operating. The dehumidier’s location should
be chosen to allow installation of this accessory if necessary.
• Do not hang the Santa Fe Ultra120V from its cabinet.
• Allow for proper routing and drainage of needed drain pipes.

The Santa Fe Ultra120V plugs into a common grounded 115 VAC outlet. The device draws 5.8 Amps at 80°F and
60% RH. Locate the dehumidier in an area where the cord’s length (9’) easily reaches a 115 VAC electrical outlet
with a minimum of 15 Amp circuit capacity. If used in an area that may become wet, a GFCI protected circuit is
recommended. Consult local electrical codes for further information.
Santa Fe offers a variety of control devices for use with the Santa Fe Ultra120V. The control is to be located
remotely from the dehumidier and placed in the space to be conditioned. A low voltage (24 Volt) control MUST be
used with the Santa Fe Ultra120V and MUST be connected with low voltage (18-22 gauge) thermostat wire.
CAUTION!
DO NOT ALLOW THE 24V TERMINAL TO CONTACT THE COM/DMPR TERMINALS ON THE
SANTA FE ULTRA120V OR DAMAGE TO THE TRANSFORMER WILL RESULT.
1. Electrical Precautions
• Do not install the control where it may not accurately sense the relative humidity such as near HVAC
supply registers, near exterior doors, on an outside wall, near a window, or near a water source.
• The screw terminals on the Santa Fe Ultra120V and the control are labeled to prevent confusion.
• Be sure to consult the electrical schematic in the CONTROLS Section (page 12) of this manual or
inside the access panel of the Santa Fe Ultra120V before making control connections.
WARNING!
THE REMOTE CONTROLS OF THE SANTA FE ULTRA120V ARE POWERED BY A LOW VOLTAGE CIRCUIT (24VAC)
AND MUST NEVER CONTACT OR BE CONNECTED TO A HIGH VOLTAGE CIRCUIT.

The Santa Fe Ultra120V generates condensate.
Place a secondary drain pan with a float switch under the dehumidier if it is suspended above a nished area or
above an area where water leakage could cause damage.
The Santa Fe Ultra120V contains an internal drain trap for proper dehumidier operation. Install a 3/4” threaded
male NPT adapter to the external condensate tting. 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 Santa Fe Ultra120V 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 float switch.
The pump also contains a safety float switch. If the pump fails, this switch opens the common control circuit
and stops water production before the reservoir overflows.

CAUTION!
DO NOT CONNECT WITH A STATIC PRESSURE GREATER THAN OR EQUAL TO +0.5 WG.
CONTACT TECHNICAL SUPPORT AT [phone] FOR ADDITIONAL DETAILS.
1. Ducting Considerations:
• All flexible ducting connected to the Santa Fe Ultra120V should be UL listed.
• A short piece of flexible ducting on all Santa Fe Ultra120V 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 round or equivalent rectangular duct for longer lengths.
• Grills or diffusers on the duct ends must not excessively restrict airflow.
• Effective dehumidication may require that ducting be branched to isolated, stagnant air flow areas. When
ducting to two or three areas, use 8” or larger diameter branch ducting. When ducting to four or more areas,
use 6” or larger diameter branch ducting. Provisions must be made to provide airflow 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.
2. Decide Where To Place The Unit.
CAUTION! ALLOW FOR ENOUGH SPACING TO PROPERLY ROUTE THE RETURN AND
SUPPLY CONNECTION
a. Attach leveling feet. b. Supply ducts can be installed on both sides of the
unit. In cases where only one of the two supply
ducts is USED, the 8” duct cover can be installed to
concentrate the air supply through one duct.
3. Place Dehumidifier On The Floor.
CAUTION! INTERNAL STOPS LIMIT FEET HEIGHT. DO NOT TIGHTEN FEET BEYOND THE
RESISTANCE PROVIDED BY STOPS.

4. Recommended HVAC System Installations
a. Attic
The recommended installation draws air from a central location through a dedicated return to the
dehumidier and ducts the supply of the dehumidier to the air supply of the HVAC system. Utilize the
optional outdoor air ventilation duct to provide outdoor air.
• Install a dedicated 10" air return for the Santa Fe Ultra120V from a central area of the structure.
• Duct the supply of the Santa Fe Ultra120V to the supply of the HVAC system with a backdraft
damper.
• If the existing system has multiple returns, instead of installing a dedicated return to the Santa Fe
Ultra120V, it is possible to select one to disconnect from the existing HVAC system and use it for
the dedicated Santa Fe Ultra120V 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.

Outdoor air ventilation is optional.
Outdoor air may be brought into the structure by connecting an insulated duct from outside the structure to the
6” inlet of the Santa Fe Ultra120V. 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 outdoor air ventilation duct should be connected to the 6” damper on the top of the Santa Fe
Ultra120V.
• An insulated 6” diameter duct can provide up to 100 CFM of outside air.
• If a motorized damper is not being used, outdoor air is controlled by the manual damper in the 6” collar
of the Santa Fe Ultra120V.
• The performance of the Santa Fe Ultra120V 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 outdoor 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 Santa Fe Ultra120V capable of year-round drying.

Option 1: Calculating Airflow Requirement Using ASHRAE 62.2-2016 Airflow Equation
ASHRAE Airflow 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

20 Santa Fe ULTRA120V Installation & Operation Instructions Santa-Fe-Products.com | 800.533.7533
A control must be used with the Santa Fe Ultra120V. Santa Fe offers the DEH 3000 proprietary control. The DEH 3000
allows homeowners to monitor and control relative humidity and proper ventilation levels in their home. This control is
also available with a remote sensing option.
NOTE: The DEH 3000 is sold separately. Other thermostats are compatible with the Santa Fe Ultra120V.
CAUTION!
DO NOT ALLOW THE 24V TERMINAL FROM THE SANTA FE ULTRA120V TO CONTACT THE COM
TERMINAL ON THE SANTA FE ULTRA120V OR DAMAGE TO THE TRANSFORMERS WILL RESULT.
a. Circuit Breaker
To prevent damage to the 24 volt control transformer, the Santa Fe Ultra120V comes with a resettable circuit
breaker. Check wiring for any electrical short and repair before resetting the breaker. Resetting the circuit
breaker without correcting the electrical short may result in transformer damage. Be sure to check the
electrical schematic in this manual or inside the access panel of the Santa Fe Ultra120V before making any
control connections. The reset button for the circuit breaker can be found on the side of the unit.
b. Control Connections
The control and the Santa Fe Ultra120V are labeled to prevent confusion. Depending on the control, some of
the screw terminals on the Santa Fe Ultra120V may not be used. Be sure to consult the electrical schematic
in this manual (see page 8) or inside the access panel of the Santa Fe Ultra120V before making control
connections.
