If dirty, the foam pre-filter can be vacuumed or carefully hand
washed with warm water and mild detergent, then rinsed. The
pleated fabric filter can generally be vacuumed clean several
times before needing replacement. Replacement filters can be
ordered from the factory or purchased locally if available.
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.
4.2 Blower Oiling
The blower motor is factory lubricated from many years of normal
operation. However, periodic oiling will extend motor bearing life.
To oil, remove the plastic cap from the two oiling tubes extending
from the unit above the humidity control (see figure 3). Add 3 to
5 drops of SAE 20 non-detergent oil to each port every 6 months.
DO NOT use thinner oil or penetrating oil. Blower life can actually
be decreased by such oil.
5. Service
CAUTION
Servicing the Santa Fe 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 for warranty claim
authorization and technical assistance.
5.2 Technical Description
The Santa Fe 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).
Blower does not run with fan switch in either position.
Compressor runs briefly but cycles ON & OFF.
1. Loose connection in blower circuit (see Fig. 2).
2. Obstruction prevents impeller rotation.
3. Defective blower.
4. Blower switch defective.
Evaporator coil frosted continuously, low dehumidifying
capacity.
1. Defrost thermostat loose or defective (Sec. 5.8).
2. Low refrigerant charge.
3. Dirty air filter or air flow restricted.
