• 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 Ultra155/205 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.

• 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.
• 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 Ultra155/205, especially when connecting
to the supply ducting system. The backdraft damper prevents supply air from counter flowing through the
Santa Fe Ultra155/205 when it is not operating. The dehumidier’s location should be chosen to allow
installation of this accessory if necessary.
• The Santa Fe Ultra155/205 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
Ultra155/205 from its’ cabinet.
• Allow for proper drainage and routing of needed drain pipes.

The Santa Fe Ultra155/205 plug into a common grounded 115 VAC outlet. Locate the dehumidier in an area where
the cord’s length (9’) easily reaches a 115 VAC electrical outlet. The Santa Fe Ultra155 requires a minimum 15 Amp
circuit. The Santa Fe Ultra205 requires a dedicated 20 Amp circuit. If used in an area that may become wet, a GFCI
protected circuit is recommended. Consult local electrical codes for further information.
Santa Fe offers a variety of control devices for use with the Santa Fe Dehumidier. The control is to be located
remotely from the dehumidier and placed in the space to be conditioned. A low voltage (24 Volt) control MUST be
used with the Santa Fe Dehumidier 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 ULTRA155/205 OR DAMAGE TO THE TRANSFORMER WILL RESULT.

• 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 Ultra155/205 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 Ultra155/205 before making control connections.
WARNING!
THE REMOTE CONTROLS OF THE SANTA FE ULTRA155/205 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 ULTRA155/205 MAY NOT BE USED WITH
CERTAIN CONTROLS AND SHOULD BE LEFT UNCONNECTED.

The Santa Fe Ultra155/205 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 Ultra155/205 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 Ultra155/205 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 Ultra155/205 dehumidier.

DRAIN INSTALLATION

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.

• All flexible ducting connected to the Santa Fe Ultra155/205 should be UL listed.
• A short piece of flexible ducting on all Santa Fe Ultra155/205 duct connections is recommended to re-
duce noise and vibration transmitted to rigid ductwork in the structure.
• Use a minimum 10" diameter round or equivalent rectangular duct for total duct lengths of up to 25'. Use
a minimum 12" 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 Ultra155/205 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 8" or larger diameter branch ducting. When ducting to four or
more areas, use 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 humid-
ity control and heat distribution throughout the structure.
• DO NOT locate the return in a bathroom or a kitchen.
