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 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 • 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 air at people. The dehumidifier should be used in the upright position.
ATTACHING DUCT COLLARS Fresh Air Ventilation Duct Fresh air ventilation is optional. A 6" diameter duct is attached to the unit. 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 A 10" 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.
ELECTRICAL REQUIREMENTS The 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. If used in an area that may become wet, a GFCI protected circuit is recommended. Consult local electrical codes for further information. A variety of control devices can be used with this dehumidifier.
DRAIN INSTALLATION Drain Port The Dehumidifier generates condensate. Place a secondary drain pan with a float switch under the dehumidifier if it is suspended above a finished Secondary Drain Pan area or above an area where water leakage could cause damage. Drain Trap 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 3/4" PVC pipe to transport the condensate to a drain.
DUCTING TO HVAC SYSTEMS The recommended installation creates a separate return for the 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 Dehumidifier to provide fresh make-up air. CAUTION! DO NOT CONNECT WITH A STATIC PRESSURE GREATER THAN OR EQUAL TO +0.5 WG. CONTACT TECHNICAL SUPPORT AT (800) 558-1711 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 10" air return for the Dehumidifier from a central area of the structure.
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 Dehumidifier. 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 fresh air ventilation duct should be connected to the 6" round collar on the front of the Dehumidifier.
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 must be used with the Dehumidifier. 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. Note: The DEH 3000 is sold separately and can be purchased through your local dealer or online. Other thermostats are compatible with the Dehumidifier.
CONTROLS Control Connections The control and the Dehumidifier are labeled to prevent confusion. Depending on the control, some of the screw terminals on the Dehumidifier may not be used. Be sure to consult the electrical schematic in this manual or inside the access panel of the Dehumidifier before making control connections. A low voltage control must be used with the Dehumidifier.
AIR FILTRATION The Dehumidifier is equipped with a MERV-13 (Dimensions: 1.75” x 14.00” x 17.50”) 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.
