2.1A In humid area, no ducting.
The simplest installation is to place the Santa Fe Classic in the
humid area with no ducting. The air inlet on top and outlet on
the side must be at least 1’ from walls and other obstructions
to air flow.
2.1B In humid area, duct inlet and/or outlet.
If the humid are is very large or has high ceilings,
dehumidification can be improved by adding an inlet and/or
outlet duct to circulate and destratify stagnant areas. For a
large are, add inlet or outlet ducting to create flow across the
area’s greatest length. For areas with ceilings higher than 12’,
use an inlet duct to draw warm, moist air from near the ceiling.
See section 2.4 for attaching duct collars & ducting.
2.1C In A Remote Area, Duct Inlet & Outlet.
It is often desirable, especially in billiard rooms and finished
areas, to install the Santa Fe Classic in an adjacent equipment
room or unfinished area. Air is transferred between the humid
room and the unit via ducting. The factory mounted humidity
control on the Santa Fe Classic cabinet may not sense the
humidity in the humid room accurately enough with this
installation method. If so, an additional humidity control can
be mounted in the humid room and wired to the Santa Fe
Classic. Local electrical codes must be followed when wiring
the control.
2.1D In A Remote Area, Duct Outlet Only.
A simpler remote installation method than above uses ducting
between the Santa Fe Classic discharge and the humid room;
the Santa Fe Classic inlet draws air from the room in which
it’s located. This works well if there is an adequate air flow
path between the two rooms; e.g. high door undercut, louvered
door or wall grill. This eliminates the need to remote mount the
humidity control. There are several potential disadvantages to
using this method. First, humid air is drawn into the room where
the Santa Fe Classic is located. Second, to accurately sense
humidity, the blower in the Santa Fe Classic may need to run
continuously to draw air from the humid room into the Santa
Fe Classic room. Third, a slight negative pressure is created
in the room with the Santa Fe Classic which could back draft
open combustion devices located there. If such devices are
present, call the factory for specific instructions before using this
installation method or consider the option below.
2.1E In A Remote Area, Duct Inlet Only.
When the Santa Fe Classic is located in a room separate
from the main area to be dehumidified, it may be desirable to
dehumidify and/or slightly pressurize that room. Pressurization
assures that open combustion devices do not back draft. This
can be accomplished by installing a duct from the humid room
to the Santa Fe Classic inlet and by allowing the Santa Fe
Classic to discharge dehumidified air into the room in which
it’s located. An adequate air flow path must exist between the
two rooms for this method to work well. An additional humidity
control may need to be mounted in the humid area and wired
to the Santa Fe Classic to accurately maintain the desired
humidity. Local electrical codes must be followed when wiring
the control.
2.2 Electrical Requirements
The Santa Fe Classic plugs into a common grounded outlet on a
15 Amp circuit. It draws between 6 and 7 Amps under normal
operating conditions.
2.3 Condensate Removal
Condensate drains by gravity via the clear hose extending from
the unit. Route hose to a floor drain. Use care to keep the hose as
flat to the floor as possible. Excessive humps or kinks will prevent
proper drainage.
If the Santa Fe Classic is located too far from a floor drain for
the attached hose to reach, 1/2" PVC pipe can be used to extend
it. It is commonly available in 10’ lengths from building supply,
plumbing and hardware stores. It will slide tightly inside the end of
the drain hose.
If more than one length of pipe is required they can be joined with
a short piece cut from the end of the drain hose.
2.4 Ducting
2.4A Optional Ducting
An inlet shroud with an 8" round collar and an 8" round
exhaust collar are available from the factory that will allow
round ducting to be attached to the inlet and/or outlet of the
Santa Fe Classic.
2.4B Ducting for Dehumidification
Ducting the Santa Fe Classic as mentioned in sections 2.1B-
2.1E requires consideration of the following points:
Duct Sizing:
For total duct lengths up to 25 feet, use a
minimum 8" diameter round or equivalent rectangular. For
longer lengths, use a minimum 10" diameter or equivalent.
Grills or diffusers on the duct ends must not excessively
restrict air flow.
Isolated Areas:
Effective dehumidification
may require that ducting be branched to isolated, stagnant
areas. Use 6" diameter branch ducting to each of two or three
areas, use 4" to each of four or more areas.
3. Operation
3.1 Humidity Control Adjustment
The dehumidifier will run continuously until relative humidity
(RH) is reduced to the humidity control dial setting. Setting the
humidity control to lower RH levels will
NOT
increase the unit’s
dehumidification rate, it will simply run longer to reduce the
area’s RH to the setting. The Santa Fe Classic unit (and refrigerant
based dehumidifiers in general) will reduce a warm space’s RH
to a lower level than that of a cool space. For example, the Santa
Fe Classic may reduce an 80° F space to 30% RH. However,
if the same space is 65° F, it may only reduce it to 40% RH. It
is therefore pointless to set the humidity control to excessively
low levels in cool rooms. Doing so will result in long periods of
ineffective dehumidifier run time. Quality humidity meters are
available from the factory and are recommended to accurately
monitor humidity levels.
