Drain Installation

The Santa Fe Oasis105 dehumidifier generates condensate.

The Santa Fe Oasis105 features a positive pressure drain that does not require a P-Trap. The unit features an industry exclusive dedicated float switch port (float switch is not provided and must be purchased separately) to shut the Oasis105 off in the event the main drain port clogs or fails. In order to use this feature the internal plug needs to be knocked out. If the Oasis105 is located above or in the living space, according to code, a secondary drain pan is to be placed under the unit and a float switch should be wired to the dehumidifier.

Product overview and control image

Use care to keep the hose as flat to the floor as possible. 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 Oasis105 dehumidifier 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. Be sure the drain height is no higher than the Oasis drain port.
An optional condensate pump kit may be installed if lift is required to remove condensate.

CAUTION!
CHECK DRAIN LINE WHEN CHANGING FILTER TO ENSURE THERE IS NO BUILD UP OF ALGAE OR SLUDGE.

Modes of Operation
Using Onboard Control
The Santa-Fe Oasis is designed for plug and play operation. Simply plug in the unit and route a condensate line to a drain. Press the Power button to turn on the unit. The unit is factory set at 55%RH. To change the RH% settings press the up and down arrows to adjust target RH%.

The unit is factory set to AUTO fan speed. This is the most efficient operating speed. Press the FAN button to toggle fan speed from AUTO to LOW, this is the slowest fan speed allowing for the quietest operating mode. Continue to press the FAN button in order to toggle to HIGH, this is a preset fan speed when the unit is ducted to insure no loss in performance for up to 0.4” of static resistance. When static pressure resistance is in excess of 0.4” but less than 1.0” of static resistance, Press and Hold the FAN button for 3 seconds, this will enter High Override mode, this changes the High setting. Press the up arrow to 99 in order to operate the fan at its maximum speed. Once High Override has been
set, when toggling between the three modes, HIGH will no longer be the factory setting it will be the overridden value. For this product the Factory default value for HIGH is 70. To return to factory default, press and Hold the FAN button for 3 seconds and use the up and down arrows to return the value to 70. In order for the unit to function correctly, the Value must remain at 70 or higher for this unit.

Using Remote / Terminal Control
To operate the unit using remote control. Press the TERMINAL button, the display will now show TC. This means terminal control. When operating in terminal control, the unit will no longer use its onboard sensors, it will turn on and off when a signal is sent. That signal can be anywhere from 4V to 30V in AC or DC configurations.

While in Terminal Control mode, the unit FAN speed is configurable based on the application. In the rare instance when an Error code is triggered on the unit, the alarm terminals will receive a 24Vac signal. When wired effectively this signal can be used to actuate a buzzer or turn on a warning light.

• When the Terminal Control button is pressed, the display will show “tc”.
• The Terminal Control button is used to activate the “DEHUM” input on the terminal block.
• This must be activated when an external control is used to control RH. When Terminal Control is active, the internal RH sensor is disabled.
• Remove the cover from the user interface to expose the terminal block inputs & outputs.

THE COM ON THE HVAC SYSTEM LOW VOLTAGE TRANSFORMER.

Air Filtration

The Santa Fe Oasis105 dehumidifier is equipped with MERV-13 air filter (89-90% ASHRAE dust spot). The filters should be checked and replaced every three to six months. Operating the unit with a dirty filter will reduce dehumidifier capacity and efficiency.
DO NOT operate the unit without a MERV-8, MERV-11 or MERV-13 filter. Filter non-compliance voids the product warranty.

CAUTION!
MAKE SURE UNIT IS OFF BEFORE CHANGING THE FILTER. FAILURE TO FOLLOW FILTER HANDLING INSTRUCTIONS MAY RESULT IN IMPROPER FUNCTION OF THE DEHUMIDIFIER AND CAUSE PREMATURE FILTER WEAR OR UNIT DAMAGE.

Changing the Filter
For greatest filtration and efficiency of the Santa Fe Oasis105 dehumidifier, it is recommended the air filters be replaced every three to six months.

Step 1 – Removing the Filter:
Remove MERV-13 filter by gently pulling on the bottom of the filter frame.

Step 2 – Replacing the Filter:
Angle the top of the MERV-13 filter under the tab and gently slide the filter into the filter slot. Do not force. If resistance is felt, check alignment for obstructions or debris inside the filter housing. Be sure the arrows on the filter are facing into the dehumidifier.

Basement/Crawl Space Installation

1. The Oasis105 must operate in an enclosed area to be most effective. Close all exterior vents, doors, windows, and other outside openings to the space. The effectiveness of the dehumidifier depends on the rate at which new moisture-laden air enters the room.
2. Place dehumidifier in a central location that does not restrict the airflow of the air intake and air outlet.
3. The dehumidifier must be installed on a level floor to ensure water drains out of the unit correctly.
4. There should be a minimum of 14 inches clearance around the dehumidifier. The unit will produce heat while in operation and should not be operated in an enclosed small space like a closet unless it is ducted.

The Oasis105 is designed to operate between 49 °F and 115 °F. If the inlet air temperature is out of this range, the unit will display an error code and not operate.

Ducting To Finished Areas (Optional)

A supply duct collar is an optional accessory for the Santa Fe Oasis105 and not included with the unit.

Attaching Supply Duct Collar
Supply Air Outlet
A 10″ diameter supply plenum and duct collar (sold separately) can be attached to the Oasis105.

Output of Dehumidified Air

Recommended Installations

• Place the Santa Fe dehumidifier in the unfinished area of the basement, near a drain access (condensate will drain via gravity or with an optional pump kit).
• Using the supply duct collar, supply the dry air from the dehumidifier into a large, open area in the  finished section of the basement.
• Place a return grill / passive vent on the other side of the wall that separates the finished and unfinished areas. This will allow for a circular air flow throughout the basement.
• The passive grill will prevent the unfinished room from being placed under a negative pressure and  also allow the dehumidifier to focus on keeping the  unfinished area dry as well.
• The onboard dehumidistat control can be used on the unit for this application or a 24 volt dehumidistat can be placed in the finished basement  as well.
• Be sure to keep all doors open to any other rooms in the basement to help with proper air circulation (bedrooms, bathrooms, etc.)
