SAFETY INSTRUCTIONS READ THE INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS CAREFULLY BEFORE INSTALLING AND OPERATING THIS DEVICE. PROPER ADHERENCE TO THESE INSTRUCTIONS IS ESSENTIAL TO OBTAIN MAXIMUM BENEFIT FROM YOUR SANTA FE WHOLE HOUSE VENTILATING DEHUMIDIFIER. WARNING! THIS SYMBOL MEANS IMPORTANT INSTRUCTIONS. FAILURE TO HEED THEM CAN RESULT IN SERIOUS INJURY OR DEATH. CAUTION! THIS SYMBOL MEANS IMPORTANT INSTRUCTIONS. FAILURE TO HEED THEM CAN RESULT IN INJURY OR MATERIAL PROPERTY DAMAGE.
DEHUMIDIFIER SET UP Important Precautions •T he 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 dehumidifier should be used in the upright position.
ATTACHING DUCT COLLARS Fresh Air Ventilation Duct Fresh air ventilation is optional. If setting up the unit to provide fresh air ventilation, see page 10. Return Air Inlet An 8” diameter duct collar is attached to the unit. Supply Air Outlet he back panel of the dehumidifier can be rotated to allow for horizontal flow through or vertical flow through T of the supply air. • Horizontal Flow Through The unit ships configured for a horizontal flow through.
ELECTRICAL REQUIREMENTS The Santa Fe Ultra70 plugs into a common grounded 115VAC outlet. The device draws 5.1 Amps at 80°F and 60% RH. 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. 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 Ultra70.
DRAIN INSTALLATION The Santa Fe Ultra70 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 run properly. 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'.
DUCTING TO HVAC SYSTEMS The recommended installation creates a separate return for the Santa Fe Ultra70 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 provide fresh make-up air (optional). 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 TO HVAC SYSTEMS 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 8" air return for the Santa Fe Ultra70 from a central area of the structure. • Duct the supply of the Santa Fe Ultra70 to the supply of the existing HVAC system with a backdraft damper.
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 a tee located in the inlet duct of the Santa Fe Ultra70. 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.
FRESH 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.
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 home. 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.
AIR FILTRATION The Santa Fe Ultra70 is equipped with a MERV-13 (Dimensions: 0.75” x 9.00” x 11.38”) air filter. The filter 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 the recommended filter. Filter non-compliance voids the product warranty. CAUTION! MAKE SURE UNIT IS OFF BEFORE CHANGING THE FILTER.

SERVICE Troubleshooting CAUTION! TROUBLESHOOTING SHOULD BE PERFORMED BY A QUALIFIED HVAC TECHNICIAN. Symptom Possible Reason Neither fan nor compressor running. Dehumidification is being called for. 1. Dehumidifier unplugged or no power to outlet. 2. Humidity control set too high. 3. Loose connection in internal or control wiring. 4. Defective compressor relay. 5. Defective control transformer. Compressor is not running. Dehumidification is being called for. Fan is running. 1.
SERVICE Troubleshooting (Continued) Symptom Possible Reason Low dehumidification capacity (evaporator is frosted continuously). Dehumidification is being called for. 1. Defrost thermostat loose or defective. 2. Low refrigerant charge. 3. Dirty air filter(s) or air flow restricted. 4. Excessively restrictive ducting connected to unit. No ventilation. Ventilation is being called for. 1. L oose connection in ventilation control circuit. 2. L oose connection in damper power circuit. 3.
