SANIDRY CSB INSTALLER'S AND OWNER'S MANUAL

SaniDry CSB Installer’s & Owner’s Manual
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 discharged from the dehumidifier. The refrigerant liquid
then passes through 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.
8.2 Troubleshooting
No dehumidification. Neither blower, nor compressor run with fan
switch AUTO.
1 Unit unplugged or no power to outlet, circuit breaker
tripped.
2 Humidity control set to “Humid” setting.
3 Loose connection in internal wiring.
4 Humidity control is defective.
No dehumidification. Compressor does not run but blower runs
with fan switch AUTO and humidity control turned to ON.
1 Defrost thermostat open, ambient temperature too low.
2 Loose connection in compressor circuit.
3 Defective compressor overload.
4 Defective compressor or compressor run capacitor.
Blower runs with fan switch AUTO but compressor
cycles on & off.
1 Low ambient temperature and/or humidity causing unit
to cycle through defrost mode.
2 Defrost thermostat defective.
3 Defective compressor overload.
4 Defective compressor.
Blower does not run with fan switch in either position.
Compressor runs briefly but cycles on and off.
1 Loose connection in blower circuit.
2 Obstruction prevents impeller rotation.
3 Defective blower.
4 Defective blower switch.
Evaporator coil frosted continuously, low dehumidifying capacity.
1 Dirty air filter or air flow restricted.
2 Defrost thermostat loose or defective.
3 Low refrigerant charge.
