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 intoo repairs.
- Avoid directing the discharge of air at people. The dehumidifier 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 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 Ultra98/120 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.
DEHUMIDIFIER SET UP
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 to prevent airflow obstruction.
- Electrical service access will require the removal of the outside shell. Allow sufficient clearance around the unit.
- Locate the dehumidifier in an area where the unit’s 9 ft. cord can easily reach the electrical outlet.
- Locate the dehumidifier in an area where field wiring the control (low voltage) to the unit will be possible.
- A back draft damper is required in the supply duct of the Santa Fe Ultra98/120, especially when connecting to the supply ducting system. The backdraft damper prevents supply air from counter-flowing through the Santa Fe Ultra98/120 when it is not operating. The dehumidifier’s location should be chosen to allow installation of this accessory if necessary.
- The Santa Fe Ultra98/120 may be suspended with the hang kit or a suitable alternative from structural members, ensuring the assembly supports the dehumidifier’s base in its entirety. Do not hang the Santa Fe Ultra98/120 from its’ cabinet.
- Allow for proper drainage and routing of needed drain pipes.
CAUTION!

Removal of Compressor Shipping Support
- The Santa Fe Ultra98/120 uses a compressor to power the refrigeration system. To protect the compressor and refrigeration system during shipping, a plastic tie wrap secures it to the unit’s frame. Remove the tie wrap by cutting the tie wrap and pulling from the unit as shown. After removing tie wrap, insert plastic plugs provided into the holes.
ATTACHING DUCT COLLARS
- Outdoor Air Ventilation Duct
- Outdoor air ventilation is optional. If setting up the unit to provide outdoor air ventilation, see page 18.
- Return Air Inlet
- A 10” diameter duct collar is attached to the unit.
- Supply Air Outlet
- The back panel of the dehumidifier can be rotated to allow for horizontal flow through or vertical flow through of the supply air.
- Horizontal Flow Through The unit ships configured for a horizontal flow through. A 10” diameter duct collar is attached to the unit.
- Vertical Flow Through Remove the exhaust panel using a T25 torx bit. Rotate the panel so the exhaust collar is located on the top of the unit. Align screw holes and snap the panel onto the base. Secure the exhaust panel to the base by replacing the six screws.
ELECTRICAL REQUIREMENTS
The Santa Fe Ultra98/120 plugs into a common grounded 115VAC outlet. Locate the dehumidifier in an area where the unit’s 9 ft. cord can easily reach 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 any further information. Santa Fe offers a variety of control devices for use with the Santa Fe Ultra98/120. The controls are to be located remotely from the dehumidifier and placed in the space to be conditioned. Low voltage (24 Volt) controls can be used with the Santa Fe Ultra98/120 and MUST be connected with low voltage (18-22 gauge) thermostat wire.
WARNING!
THE REMOTE CONTROLS OF THE SANTA FE ULTRA98/120 ARE POWERED BY A LOW VOLTAGE CIRCUIT (24VAC) AND MUST NEVER CONTACT OR BE CONNECTED TO A HIGH VOLTAGE CIRCUIT.
CAUTION!
DO NOT ALLOW THE 24V TERMINAL TO CONTACT THE COM/DMPR TERMINALS ON THE SANTA FE ULTRA98/120 OR DAMAGE TO THE TRANSFORMER WILL RESULT.
CAUTION!
SOME OF THE SCREWS TERMINALS ON THE SANTA FE ULTRA98/120 MAY NOT BE USED WITH CERTAIN CONTROLS AND SHOULD BE LEFT UNCONNECTED.
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 Ultra98/120 and the control are labeled to prevent confusion.
- Be sure to consult the electrical schematic in the CONTROLS Section (pages 20-21) of this manual or inside the access panel of the Santa Fe Ultra98/120 before making control connections.
ELECTRICAL REQUIREMENTS
Wiring Schematics
DRAIN INSTALLATION
The Santa Fe Ultra98/120 generate condensate.
Place a secondary drain pan with a float switch under the dehumidifier if it is suspended above a finished area or in an area where water leakage could cause damage. A drain trap is required for the dehumidifier to run properly (see diagram below). 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 Santa Fe Ultra98/120 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. 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 Ultra98/120 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 Ultra98/120 dehumidifier.
Drain Installation
- Dehumidifiers commonly use a negative air pressure drain pan. This causes air to flow backwards thru the drain system which can cause water to pool inside the dehumidifier and leak. A drain trap prevents this issue by trapping water in the pipe to stop air from flowing backwards.
- Please see the trap diagram below. This assembly can be made with common ¾” PVC pipe fittings. The pipe
- measurements and placement of the cap and vent are critical to the function of the trap. Once trap is assembled, be sure to fill with water.
DUCTING TO HVAC SYSTEMS
CAUTION!
DO NOT CONNECT WITH A STATIC PRESSURE GREATER THAN OR EQUAL TO +0.5 WG. CONTACT TECHNICAL SUPPORT AT 800-533-7533 FOR ADDITIONAL DETAILS.
Ducting Considerations:
- All flexible ducting connected to the Santa Fe Ultra98/120 should be UL listed.
- A short piece of flexible ducting on all Santa Fe Ultra98/120 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 or equivalent for longer lengths.
- Grills or diffusers on the duct ends must not excessively restrict airflow.
- A length of 8″ or more of insulated flex duct or any other vibration isolating material on the outlet of the Santa Fe Ultra98/120 will reduce air noise from the blower.
- 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 humid-ity control and heat distribution throughout the structure.
- DO NOT locate the return in a bathroom or a kitchen.
Decide Where To Place The Unit.
CAUTION! ALLOW FOR ENOUGH SPACING TO PROPERLY ROUTE THE RETURN AND SUP-PLY CONNECTION
Choose Weather To Place On Floor Or Hang Dehumidifier.
CAUTION! INTERNAL STOPS LIMIT FEET HEIGHT. DO NOT TIGHTEN FEET BEYOND THE RESISTANCE PROVIDED BY STOPS.
DUCTING TO HVAC SYSTEMS
- Recommended HVAC System Installations
Attic
The recommended installation draws air from a central location through a dedicated return to the dehumidifier and ducts the supply of the dehumidifier 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 Ultra98/120 from a central area of the structure.
- Duct the supply of the Santa Fe Ultra98/120 to the supply of the HVAC system with a backdraft damper.

No Duct – Central Return to HVAC Return
Attach outlet duct with a vertical flow through so air is not discharged into wall or other obstruction. The HVAC system will naturally pull dehumidifier air from the closet and distribute it throughout the structure.
OUTDOOR AIR VENTILATION
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 Ultra98/120. 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” round collar on the front of the Santa Fe Ultra98/120.
- An insulated 6” diameter duct can provide up to 75 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 Ultra98/120.
- Performance of the Santa Fe Ultra98/120 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 Ultra98/120 capable of year-round drying.
Outdoor Air Ventilation With Dehumidifier Off and Fan Only Operation
Outside air mixes with return air prior to beginning the dehumidification process. Outside and inside temperature and relative humidity will impact the combined outlet air conditions.
OUTDOOR AIR VENTILATION
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 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
Record the required CFM ____________
Option 2: Calculating Airflow Requirement Using Table 4.1 from ASHRAE 62.2-2019 Ventilation Air Requirements, CFM
CONTROLS
A control must be used with the Santa Fe Ultra98/120. 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.

WARNING!
ELECTRICAL SHOCK HAZARD: Electrical power must be present to perform some tests. These tests should be performed by a qualified service person. Troubleshooting Procedure for Control Related Issues This method of diagnosis is used to function check the internal components in the dehumidifier. 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 off position – Did the unit shut off? 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 dehumidifier will produce little to no water.) 7. Collecting the water removed in a 24 hour period will give a measurement of performance. |
