(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 your dealer or online and are recommended to
accurately monitor humidity levels.
3.2 Fan Switch
Turning “ON" the fan switch 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.
4. Maintenance
4.1 Air Filter
The Santa Fe Classic is equipped with 2 air filters. A foam pre-
filter followed by a standard MERV-11 65% efficient pleated
fabric filter. These should be checked every three to six months.
Operating the unit with dirty filters will reduce dehumidifier
capacity and efficiency and may cause the compressor to cycle
off and on unnecessarily on the defrost control.
If dirty, the foam pre-filter can be vacuumed. The pleated fabric
filter can generally be vacuumed clean several times before
needing replacement. Replacement filters can be ordered from
your dealer or online.
DO NOT
operate the unit without the filters
or with a less effective filter. The heat exchange coils inside the
unit could become clogged and require disassembly to clean.
5. Service
CAUTION!
Servicing the Santa Fe Classic 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.
5.1 Warranty
A warranty certificate has been enclosed with this unit. Read it
before any repair is initiated. If a warranty repair is required, call
the factory first at 1-800-533-7533, Ext. 8459 for warranty claim
authorization and technical assistance.
5.2 Technical Description
The Santa Fe Classic 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 (see figure 1).
Hot, high pressure refrigerant gas is routed from the compressor
to the condenser coil (see figure 1). 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 refrigerant during normal
operation. A flooded evaporator should maintain constant pressure
and temperature across the entire coil, from inlet to outlet.
The mixture of gas and liquid refrigerant enter the accumulator
after leaving the evaporator coil. The accumulator prevents any
liquid refrigerant from reaching the compressor. The compressor
evacuates the cool refrigerant gas from the accumulator and
compresses it to a high pressure and temperature gas to repeat
the process.
5.3 Troubleshooting
No dehumidification. Neither blower nor compressor run with
fan switch “FAN AUTO”.
1. Unit unplugged or no power to outlet.
2. Humidity control set too high or defective
(Sec. 3.1 & 5.7).
3. Loose connection in internal wiring.
No dehumidification. Compressor does not run but blower
runs with fan switch “FAN AUTO” and humidity control turned
to ON (all the way clockwise).
1. Defective compressor or compressor run capacitor
(Sec. 5.6).
2. Loose connection in compressor circuit (see Fig. 2).
3. Defective compressor overload (Sec. 5.6A).
4. Defective compressor (Sec. 5.6).
5. Defrost thermostat open (Sec. 5.8).
Blower runs with fan switch “FAN AUTO”, but compressor cycles
ON & OFF.
1. Low ambient temperature and/or humidity causing
unit to cycle through defrost mode.
2. Defective compressor overload (Sec. 5.6A).
3. Defective compressor (Sec. 5.6).
4. Defrost thermostat defective (Sec. 5.8).
