Product Overview

Santa Fe Impact XT is the best way to economically dehumidify your crawlspaces and basements. All Santa Fe dehumidifiers work by using their refrigeration systems to collect the water from the surrounding air. The air is cooled so that the moisture condensates onto a coil, which collects and directs the water into the drain hose, by the force of gravity. The dehumidified air is then used to help with the cooling process before being reheated and released through the exhaust vents on the sides of the dehumidifier.

The features of the Santa Fe Impact XT include:

  • Low Temperature Operation - Working at temperatures that other dehumidifiers just can't handle, the Santa Fe Impact XT keeps working diligently.
  • Auto Restart - All Santa Fe dehumidifiers have automatic restart capability after any power outage. They even keep all the settings.
  • Large Capacity - The Santa Fe Impact XT can remove a large amount of moisture from the air, up to 105 pints a day out of a 2500 sq. ft. area, doing the job of several competing dehumidifiers.
  • Superior Air Filtration - Using MERV-11 filters, the Santa Fe Impact XT keeps working at full efficiency when other dehumidifiers would struggle on slowly.
  • High Energy Efficiency - All Santa Fe dehumidifiers exceed the Energy Star efficiency ratings, but the Santa Fe Impact XT exceeds it by 50%.

How does Santa Fe prevent humidity from damaging your property? The Santa Fe dehumidifiers prevent mold, mildew and pests from ever growing, keeping your property safe from any damage these might cause and keep your home environment comfortable and healthy. 

Dehumidifiers are important because wet crawlspaces and basements are the main factor for the eventual destruction of floor joists, beams, insulation, and electrical and mechanical systems. Excessive moisture encourages the growth of mold on wood and on other organic material in crawl spaces. All these things lead to a large amount of damage to your property. This Impact XT dehumidifier will remove moisture from your basement or crawlspaces to prevent the growth of mildew, rust, mold, biological allergens, musty odors, bacteria and even dust mites and other pests. 

All Santa Fe dehumidifiers work by using their refrigeration systems to collect the water from the surrounding air. The air is cooled so that the moisture condensates onto a coil, which collects and directs the water into the drain hose, by the force of gravity. The dehumidified air is then used to help with the cooling process before being reheated and released through the exhaust vents on the sides of the dehumidifier.

The EPA recommends keeping humidity levels below 50%, to keep all those issues from occuring. Just attach a tube to the water output valve, place the tube where you want it to go, plug the dehumidifier in and watch it go. The dehumidifer works in all environments as well, including wine cellars, gun vaults, home libraries, car collections, and historical homes.

With a power draw of less then 5 amps, you can see why Santa Fe Impact XT is the best choice for energy efficient dehumidifier that Santa Fe has. Just attach a hose to the dehumidifier, run the tube to a drain or other area to release the water, plug in the dehumidifier and just wait for the Santa Fe Impact XT to do its work.

Two optional accessories provide the best flexibility in installation.

Manufacturer Santa Fe Dehumidifiers (Mfg. Number: 4032230)


Capacities for residential dehumidifers are measured in pints of water removed per day at standard conditions (80 degrees F and 60% RH) determined by the American Home Appliance Manufacturers. At these conditions, the capacity of the Santa Fe Impact is 105 pints per day as compared to 20 - 65 pints from standard residential units. However, most basements and crawlspaces are cooler than 80 degrees F so the water removal capacity of the standard unit will be lowered significantly. A large dehumidifier such as the Santa Fe Impact is necessary that moisture is removed at real world temperature of your crawlspace or basement to prevent mold, bacteria and mildew growth. This Santa Fe Impact is designed for these cooler applications.

Intended Application(s)
The Santa Fe Impact is intended for use in crawlspaces or basements: however, the unit can be placed in almost any residential setting where dehumidification is desired. Use in non-residential applications and pool areas may void warranty. The Santa Fe Impact is designed to operate in temperatures between 56° and 95°F. In order to efficiently control humidity levels, the area in which the dehumidifier is to be operated must be free of water intrusion or excessive fresh (outside) air infiltration. Before installing the Santa Fe Impact, water intrusion and air infiltration problems should be addressed.


Remove compressor shipping tie from the unit. Failure to remove shipping tie will cause excess vibration to be transmitted to the frame.

Remove Compressor Shipping Support
The Santa Fe Impact 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 units 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.

The Santa Fe Impact can be installed in a variety of locations to meet the owner’s needs; other considerations include:

Electrical Requirements
The Santa Fe Impact plugs into a common grounded outlet on a 110-120 VAC 15-Amp circuit. Use of a ground fault circuit interrupter (GFCI) protected circuit is recommended. The unitshould not be used in areas prone to flooding.

Condensate (Water) Removal
The Santa Fe Impact drains via gravity, therefore, it does not have the ability to push condensate (water) upwards. The drain hose must run down towards the drain location. Condensate can be drained by using the 5/8” clear vinyl hose and the 3/4” threaded adapter provided. Ensure the threaded adapter is threaded in tightly. The Santa Fe Impact requires a drain trap. Creating a drain trap allows a small amount of water to build up in the trap area of the clear hose. This prevents air from back flowing through the hose and into the dehumidifier; essentially causing the unit to backflow water out of the corners of the machine. Position the trap in the hose approximately 8"-10” from the dehumidifier and make sure the highest point of the trap is still at least 2”below the black drain port adapter on the dehumidifier. If the highest point of the trap is above the drain port, water will back flow into the dehumidifier. Check the hose regularly to ensure water is draining properly. For additional information on how to create a proper trap, see our instructional video at:

Use care to keep the hose as flat to the floor as possible after your trap is in place. Be sure the hose is not kinked or otherwise restricted so water can pass through the hose freely. Improper installation of the drain hose may result in water leakage. If the Santa Fe Impact is located too far from the floor drain and the provided hose does not reach, you may use a 1/2” PVC rigid pipe to extend the drain. Rigid PVC tubing is readily available from your local hardware store. Be sure the extension is at a down-word slope to the drain. An optional condensate pump kit may be installed if lift is required to remove condensate.

A factory designed return duct kit can be purchased to accept 12" ducting. Contact your dealer or order online.

Humidity Control Adjustment

The humidity control is an adjustable switch that closes when the relative humidity of the air in which it is located rises to the dial set point. It opens when the RH drops 4 to 6% below the set point.

Approximate Humidity Levels Per Setting
“Drier” 20% to 30% Relative Humidity
“Normal” 45% to 55% Relative Humidity (Recommended)
“Humid” 80% to 90% Relative Humidity

The dehumidifier will run until the relative humidity (RH) is reduced to the humidity control dial setting.
Quality humidity meters are available from the factory and are recommended to accurately monitor humidity levels. Contact your dealer or call 1-800-533-7533 to order.

Fan Switch
Turning the fan switch to “FAN ON” will cause the unit’s internal fan to run continuously, whether the unit is dehumidifying or not. This function is desirable if the unit is used for air circulation. Turning the fan switch to “FAN AUTO” will cause the unit’s internal fan to run only while the unit is dehumidifying.


NOTE: Do not operate the unit without the filter or with a less effective filter. The heat exchange coils inside the unit could become clogged and require disassembly to clean.

Air Filter
The Santa Fe Impact ships with a standard MERV 11 efficient pleated fabric filter. This should be checked every three to six months. The pleated fabric filter can generally be vacuumed clean several times before needing replacement. Operating the unit with a dirty filter will reduce dehumidifier capacity and efficiency and may cause the compressor to cycle on and off unnecessarily. Replacement filters can be ordered from your dealer or online at www.


Servicing the Santa Fe Impact 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. Only qualified service people should service this unit.

Technical Description
The Santa Fe Impact uses a refrigeration system similar to an air conditioner’s to remove heat and moisture from incoming air, and add heat to the air that is discharged. 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 air that is about to be discharged from the unit. The refrigerant liquid then passes through a filter/drier and capillary tubing which cause 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 flooded condition, which means that all the evaporator tubes contain liquid refrigerant during normal operation. A flooded evaporator should maintain constant pressure and temperature across the entire coil, from inlet to outlet. The mixture of gas and liquid refrigerant enter the accumulator after 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 gas to repeat the process.

Questions & Answers

Have a question about this product?
Does Impact XT have to be vented outside when used in crawl space?
No, the Santa Fe Impact XT does not need to vented outside per the manufacturer. This will defeat the purpose of using the machine to dehumidify by letting the warm air out. Also, depending on the conditions, it is recommended to change the filter every 3-6 months.
