Santa Fe ULTRA70 Installation & Operation Instructions Santa-Fe-Products.com | 800.533.7533
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 dehumidier 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 oers a variety of control devices for use with the Santa Fe Ultra70. The controls are to be located
remotely from the dehumidier and placed in the space to be conditioned. Low voltage (24 Volt) controls can be
used with the Santa Fe Ultra70 and MUST be connected with low voltage (18-22 gauge) thermostat wire.
ELECTRICAL REQUIREMENTS
CAUTION!CAUTION!
DO NOT ALLOW THE 24V TERMINAL TO CONTACT THE COM/DMPR TERMINALS ON THE
SANTA FE ULTRA70 OR DAMAGE TO THE TRANSFORMER WILL RESULT.
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 Ultra70 and the control are labeled to prevent confusion.
• Be sure to consult the electrical schematic in the CONTROLS Section (page 12) of this manual or
inside the access panel of the Santa Fe Ultra70 before making control connections.
WARNING!WARNING!
THE REMOTE CONTROLS OF THE SANTA FE ULTRA70 ARE POWERED BY A LOW VOLTAGE CIR-
CUIT (24VAC) AND MUST NEVER CONTACT OR BE CONNECTED TO A HIGH VOLTAGE CIRCUIT.
CAUTION!CAUTION!
SOME OF THE SCREWS TERMINALS ON THE SANTA FE ULTRA70 MAY NOT BE USED WITH
CERTAIN CONTROLS AND SHOULD BE LEFT UNCONNECTED.
