5.2 Return Duct Kit (P/N 4032229)
A factory designed return 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.
4031882
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.
Contact your dealer or call 1-800-533-7533 to order.
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 Impact ships with a standard MERV 11 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 1-800-533-7533.
8. Service
WARNING!
Servicing the Santa Fe
Impact 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 Impact 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
