5.2 Inlet Duct Kit (P/N 4028610)
A factory designed inlet duct kit can be purchased to accept
12" ducting. Contact your dealer or call 1-800-533-7533 to
order.
6. Operation
6.1 Humidity Control Adjustment
The humidity control is an adjustable switch that closes when
the relative humidity of the air in which it is located rises to
the dial set point. It opens when the RH drops 4 to 6% below
the set point.
Approximate Humidity Levels Per Setting
“Dry”
20% to 30% Relative Humidity
“Normal” 50% Relative Humidity (Recommended)
“Humid” 80% to 90% Relative Humidity
The dehumidifier will run until the relative humidity (RH) is
reduced to the humidity control dial setting.
Quality humidity meters are available from the factory and
are recommended to accurately monitor humidity levels.
Refer to the options and accessories table in this document.
6.2 Blower (Fan) Switch
Turning the blower switch to
“FAN ON”
will cause the unit’s
internal blower to run continuously, whether the unit is
dehumidifying or not. This function is desirable if the unit is
used for air circulation.
Turning the blower switch to
“FAN AUTO”
will cause
the unit’s internal blower to run only while the unit is
dehumidifying.
7. Maintenance
WARNING!
NOTE: Do not operate the unit
without the filter or with a less effective filter. The
heat exchange coils inside the unit could become
clogged and require disassembly to clean.
7.1 Air Filter
The Santa Fe Max Dry Dual XT ships with a standard MERV
6 efficient pleated fabric filter. This should be checked
every six months. The pleated fabric filter can generally be
vacuumed clean several times before needing replacement.
Operating the unit with a dirty filter will reduce dehumidifier
capacity and efficiency and may cause the compressor to
cycle on and off unnecessarily. Replacement filters can be
ordered from your dealer or by calling 1-800-533-5333.
8. Service
WARNING!
Servicing the Santa Fe Max
Dry Dual XT with its high pressure refrigerant
system and high voltage circuitry presents a
health hazard which could result in death, serious
bodily injury, and/or property damage. Only
qualified service people should service this unit.
8.1 Technical Description
The Santa Fe Max Dry Dual XT uses a refrigeration system
similar to an air conditioner’s to remove heat and moisture
from incoming air, and add heat to the air that is
discharged. Hot, high pressure refrigerant gas is routed from
the compressor to the condenser coil. The refrigerant is
cooled and condensed by giving up its heat to the air that is
about to be discharged from the unit. The refrigerant liquid
then passes through a filter/drier and capillary tubing which
cause the refrigerant pressure and temperature to drop. It
next enters the evaporator coil where it absorbs heat from
the incoming air and evaporates.

The evaporator operates in a flooded condition, which
means that all the evaporator tubes contain liquid
