1. 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 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 dehumidier should be used in the upright position.
• If used near a water source; be certain there is no chance the unit could fall into the water or get splashed
and that it is plugged into a dedicated circuit and Ground Fault Circuit Interrupter (GFCI) protected outlet.
• DO NOT use the dehumidier as a bench or table.
• Do not place the dehumidier directly on structural building members without vibration absorbers or
unwanted noise may result. Place the Santa Fe Ultra70 on supports to raise the base of the unit.
• A drain pan with a float switch must be placed under the dehumidier if installed above a living area or above
an area where water leakage could cause damage.

2. Location Considerations
• Allow sufcient clearance to handle the unit’s overall dimensions as well as the necessary return and
supply ductwork to the unit.
• Allow sufcient clearance for lter removal and to prevent airflow obstruction.
• Electrical service access will require the removal of the outside shell. Allow sufcient clearance around the
unit.
• Locate the dehumidier in an area where the unit’s 9 ft. cord can easily reach electrical outlet.
• Locate the dehumidier in an area where eld wiring the control (low voltage) to the unit will be possible.
• A back draft damper is required in the supply duct of the Santa Fe Ultra70, especially when connecting to
the supply ducting system. The backdraft damper prevents supply air from counter flowing through the
Santa Fe Ultra70 when it is not operating. The dehumidier’s location should be chosen to allow installation
of this accessory if necessary.
• The Santa Fe Ultra70 may be suspended with the hang kit or a suitable alternative from structural members,
ensuring the assembly supports the dehumidier’s base in its entirety. Do not hang the Santa Fe Ultra70
from its’ cabinet.
• Allow for proper drainage and routing of needed drain pipes.

1. Outdoor Air Ventilation Duct
Outdoor air ventilation is optional. If setting up the unit to provide outdoor air ventilation, see page 10.
2. Return Air Inlet
An 8” diameter duct collar is attached to the unit.
3. Supply Air Outlet
An 8” diameter duct collar is attached to the unit. The back panel of the dehumidier can be rotated to allow for
horizontal flow through or vertical flow through of the supply air.
a. Horizontal Flow Through
The unit ships congured for a horizontal flow through.
b. Vertical Flow Through
Remove the exhaust panel using a T20 torx bit. Rotate the panel so the exhaust collar is located on the top
of the unit. Align screw holes and snap the panel onto the base. Secure the supply panel to the base by
replacing the six screws.

The Santa Fe Ultra70 plugs into a common grounded 115VAC outlet and draws 5.1 Amps. Locate the
dehumidier in an area where the unit’s 9 ft. cord can easily reach 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. The controls are to be located
remotely from the dehumidier 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.
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.
1. 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!
THE REMOTE CONTROLS OF THE SANTA FE ULTRA70 ARE POWERED BY A LOW VOLTAGE CIRCUIT (24VAC)
AND MUST NEVER CONTACT OR BE CONNECTED TO A HIGH VOLTAGE CIRCUIT.
CAUTION!
SOME OF THE SCREWS TERMINALS ON THE SANTA FE ULTRA70 MAY NOT BE USED WITH
CERTAIN CONTROLS AND SHOULD BE LEFT UNCONNECTED.

The Santa Fe Ultra70 generates condensate.
Place a secondary drain pan with a float switch under the dehumidier if it is suspended above a nished area or
in an area where water leakage could cause damage.
A drain trap is required for the dehumidier to run properly (see diagram below). 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'.
An optional condensate pump kit is available for use with the Santa Fe Ultra70 and may be installed if lift is
required to dispose of condensate. Condensate is automatically pumped to a remote location when the water
level in the pump’s reservoir rises to close the float switch.
The pump also contains a safety float switch. The white leads from this switch extend from beneath the pump
cover. This switch should be installed in series with the eld wire that connects to the common lead from the
Santa Fe Ultra70 to the control panel. If the pump fails, this switch opens the common control circuit and stops
water production before the reservoir overflows. Contact a qualied electrician to install the safety float switch to
the Santa Fe Ultra70 dehumidier.

Dehumidiers commonly use a negative air pressure drain pan. This causes air to flow backwards thru the drain
system which can cause water to pool inside the dehumidier and leak. A drain trap prevents this issue by trapping
water in the pipe to stop air from flowing backwards.
Please see the trap diagram below. This assembly can be made with common ¾” PVC pipe ttings. The pipe
measurements and placement of the cap and vent are critical to the function of the trap. Once trap is assembled, be
sure to ll with water.

CAUTION!
DO NOT CONNECT WITH A STATIC PRESSURE GREATER THAN OR EQUAL TO +0.5 WG.
CONTACT TECHNICAL SUPPORT AT [phone] FOR ADDITIONAL DETAILS.
Ducting Considerations:
• All flexible ducting connected to the Santa Fe Ultra70 should be UL listed.
• A short piece of flexible ducting on all Santa Fe Ultra70 duct connections is recommended to reduce
noise and vibration transmitted to rigid ductwork in the structure.
• Use a minimum 8" diameter round or equivalent rectangular duct for total duct lengths of up to 25'. Use
a minimum 10" diameter or equivalent for longer lengths.
• Grills or diffusers on the duct ends must not excessively restrict airflow.
• A length of 8" or more of insulated flex duct or any other vibration isolating material on the outlet of the
Santa Fe Ultra70 will reduce air noise from the blower.
• Effective dehumidication may require that ducting be branched to isolated, stagnant air flow areas.
When ducting to two or three areas, use 6" or larger diameter branch ducting. When ducting to four or
more areas, use 4" - 6" or larger diameter branch ducting. Provisions must be made to provide airflow
from supply locations to the central return location. Proper air distribution is important to ensure even
humidity control and heat distribution throughout the structure.
• DO NOT locate the return in a bathroom or a kitchen.
Decide Where To Place The Unit.
CAUTION! ALLOW FOR ENOUGH SPACING TO PROPERLY ROUTE YOUR RETURN AND SUP-
PLY CONNECTION
a. If You Place On Floor
Attach leveling feet and use
vibration pads and/or risers.
b. If You Hang Dehumidifier
