DEHUMIDIFIER SET UP

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 one of the side panels for maintenance and service.
• Avoid directing the discharge of air at people.
• 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 dehumidifier as a bench or table.
• DO NOT place the dehumidifier directly on structural building members without vibration absorbers or unwanted noise may result. Place the Santa Fe Dehumidifier on supports to raise the base of the unit.
• A drain pan with a float switch MUST be placed under the dehumidifier if installed above a living area or above an area where water leakage could cause damage.

Location Considerations

• Allow sufficient clearance to handle the unit’s overall dimensions as well as the necessary return and supply ductwork to the unit.
• Allow sufficient clearance for filter removal and prevent airflow obstruction.
• Electrical service access will require the removal of a side panel. Allow sufficient clearance on a side of the unit.
• Locate the dehumidifier 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. The Santa Fe Ultra205 requires a dedicated 20 Amp circuit.
• Locate the dehumidifier in an area where field-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 Dehumidifier, especially when connecting to the supply ducting system. The backdraft damper prevents supply air from counterflowing through the Santa Fe Dehumidifier when it is not operating. The dehumidifier’s location should be chosen to allow the installation of this accessory if necessary.
• The Santa Fe Dehumidifier may be suspended from structural members with steel hanger straps or a suitable alternative, ensuring the assembly supports the dehumidifier’s base in its entirety. DO NOT hang the Santa Fe Dehumidifier from its cabinet.
• Allow for proper routing and drainage of needed drain pipes.

ATTACHING DUCT COLLARS

Duct Collar Installation
Remove the two round ducts, oval duct, oval duct seal, and a small bag of mounting hardware from inside the rectangle opening.
Fresh Air Ventilation Duct
Fresh air ventilation is optional. Attach a 6″ diameter duct to the unit using the screws provided. The 6″ duct should be capped if fresh air is not desired. If setting up the unit to provide fresh air ventilation, see page 10.
Return Air Inlet
Attach a 10″ diameter duct collar to the unit with the screws provided.
Supply Air Outlet
Adhere seal onto the back of the oval duct and mount the duct to the front of the dehumidifier using the screws provided.

ELECTRICAL REQUIREMENTS

The Santa Fe Dehumidifier plugs into a common grounded 115 VAC outlet. Locate the dehumidifier in an area where the cord’s length (9′) easily reaches a 115 VAC electrical outlet with a minimum of 15 Amp circuit capacity. The Santa Fe 205H requires a dedicated 20 Amp circuit. 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 Dehumidifier. The control is to be located remotely from the dehumidifier and placed in the space to be conditioned. A low voltage (24 Volt) control MUST be used with the Santa Fe Dehumidifier and MUST be connected with a low voltage (18-22 gauge) thermostat wire.

WARNING!
THE REMOTE CONTROLS OF THE SANTA FE DEHUMIDIFIER ARE POWERED BY A LOW VOLTAGE CIRCUIT (24 VAC) AND MUST NEVER CONTACT OR BE CONNECTED TO A HIGH VOLTAGE CIRCUIT.
CAUTION!
DO NOT ALLOW THE WIRE FROM THE 24V TERMINAL TO MAKE CONTACT WITH THE WIRE FROM THE COM TERMINAL OR DAMAGE TO THE TRANSFORMER WILL RESULT.
CAUTION!
SOME OF THE TERMINAL CONTROLS ON THE SANTA FE DEHUMIDIFIER MAY BE USED WITH CERTAIN CONTROLS.

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 Dehumidifier 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 Dehumidifier before making control connections.

Wiring Diagram

DRAIN INSTALLATION

The Santa Fe Dehumidifier generates condensate.
Place a secondary drain pan with a float switch under the dehumidifier if it is suspended above a finished area or above an area where water leakage could cause damage. A drain trap is required for the dehumidifier to drain properly. Install a 3/4″ threaded male NPT adapter to the drain pan. Install a drain pipe assembly utilizing a 3/4″ PVC pipe to transport the condensate to a drain. The Pitch of the drain should be 1″ per 10′.
An optional condensate pump kit is available for use with the Santa Fe Dehumidifier and may be installed if the 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. The white leads from this switch extend from beneath the pump cover. This switch should be installed in series with the field wire that connects to the common lead from the Santa Fe Dehumidifier to the control panel. If the pump fails, this switch opens the common control circuit and stops water production before the reservoir overflows. Contact a qualified electrician to install the safety float switch to the Santa Fe Dehumidifier.
Note: An optional condensate pump kit and an automatic cut-off device can be purchased through your dealer or online.

DUCTING TO HVAC SYSTEMS

The recommended installation creates a separate return for the Santa Fe Dehumidifier 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 the 6″ collar of the Santa Fe Dehumidifier to provide fresh make-up air.
Adjust the damper in the duct to provide the desired amount of fresh air.

CAUTION!
DO NOT CONNECT WITH A STATIC PRESSURE GREATER THAN OR EQUAL TO +0.5 WG. CONTACT TECHNICAL SUPPORT AT800-533-7533 FOR ADDITIONAL DETAILS.

Ducting Considerations:

• All flexible ducting connected to the Santa Fe Dehumidifier should be UL listed.
• A short piece of flexible ducting on all Santa Fe Dehumidifier duct connections is recommended to reduce noise and vibration transmitted to rigid ductwork in the structure.
• Use a minimum 10″ diameter round or equivalent rectangular duct for total duct lengths of up to 25′. Use a minimum 12″ diameter round or equivalent rectangular duct for longer lengths.
• Grills or diffusers on the duct ends must not excessively restrict airflow.
• Effective dehumidification 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.

Recommended HVAC System Installation
The recommended installation draws air from a dedicated indoor air return and ducts the supply of the dehumidifier to the air supply of the existing HVAC system. Utilize the optional fresh air ventilation duct to provide outside air.

• Install a dedicated air return for the Santa Fe Dehumidifier from a central area of the structure.
• Install an insulated duct from outside to the 6″ collar of the Santa Fe Dehumidifier to provide fresh air ventilation (optional).
• Duct the supply of the Santa Fe Dehumidifier to the supply of the existing HVAC system with a backdraft damper.
• DO NOT locate return in a bathroom or kitchen.
• Control should be located remotely from the dehumidifier and placed in a central location.

Please visit our website at www.Santa-Fe-Products.com/install- options/ for more installation options.

Dedicated Santa Fe Return to HVAC Supply

FRESH AIR VENTILATION

Fresh air ventilation is optional.
Fresh air may be brought into the structure by connecting an insulated duct from outside the structure to the 6″ inlet of the Santa Fe Dehumidifier. 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 Santa Fe Ultra70.
• An insulated 6″ diameter duct on the 155H and 205H provides up to 100 CFM of outside air.
• If a motorized damper is not being used, fresh air is controlled by the manual damper in the 6″ collar of the Santa Fe Dehumidifier.
• The performance of the Santa Fe Dehumidifier 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 Santa Fe Dehumidifier capable of year-round drying.

Fresh Air Ventilation With Dehumidifier Off and Fan Only Operation
Outside air mixes with the dehumidifier’s return air before being supplied to the home. Outside temperature, inside temperature, and relative humidity will impact the combined outlet air conditions.

Note: Temperature and relative humidity may vary depending on the duct distribution scheme.

Determine Ventilation Requirements
The MINIMUM ventilation requirement is calculated using ASHRAE 62.2-2016. Use one or both of the options below to determine your ventilation requirement. Follow all local and national building and safety codes.
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
2500 square foot house with 3 bedrooms, 4 occupants = [2500 X 0.03] + [(3+1) X 7.5] = 105 CFM
Example 2: Number of Occupants
2500 square foot house with 3 bedrooms, 5 occupants = [2500 X 0.03] + [5 X 7.5] = 112.5 CFM

Record the required CFM ____

CONTROLS

A control can be used with the Santa Fe Ultra70. Santa Fe offers the DEH 3000 proprietary control. The DEH 3000 monitors and controls relative humidity and proper ventilation levels in their homes. This control is also available with a remote sensing option. The Santa Fe Ultra70 features a built-in dehumidistat control as well as the ability to wire a remote-mounted control to the unit. If the Santa Fe Ultra70 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 Santa Fe Ultra70 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 separately and can be purchased online or through your local dealer. Other thermostats are compatible with the Santa Fe Ultra70.
