4.1 Technical Description
The Phoenix 200 HT uses a refrigeration system similar 
to an air conditioner’s to remove heat and moisture from 
incoming air and to 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 
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 to repeat the process.
4.2 Troubleshooting
No dehumidification, neither blower nor compressor run 
and power switch does not light when ON.
.   Unit unplugged or no power to outlet.
2.   Power switch defective.
3.   Loose connection in internal wiring.
No dehumidification, neither blower nor compressor run 
with power switch ON and lit.
.   Low pressure control open.
2.   Power switch defective.
3.   Loose connection in internal wiring.
Figure 4: Refrigeration system
Some dehumidification, blower runs continuously but 
compressor only runs sporadically.
.   Unit is in defrost cycle.
2.   Defrost thermostat defective or loose.
3.   Loose connection in compressor circuit.
4.   Defective compressor overload.
5.   Defective compressor.
6.   Defective relay.
No dehumidification, blower runs but compressor does not.
.   Bad connection in compressor circuit.
2.   Pump safety switch closed.
3.   Defective compressor capacitor.
4.   Defective compressor overload.
5.   Defective compressor.
6.   Defective relay.
Blower does not run. Compressor runs briefly but cycles on 
and off.
.   Loose connection in blower circuit.
2.   Obstruction prevents impeller rotation.
3.   Defective blower.
Unit removes some water but not as much as expected.
.   Air temperature and/or humidity have dropped.
2.   Humidity meter and/or thermometer used are out of 
calibration.
3.   Unit has entered defrost cycle.
4.   Air filter dirty.
5.   Defrost timer incorrectly set for conditions.
6.   Defective defrost thermostat.
7.   Low refrigerant charge.
8.   Air leak such as loose cover.
9.   Defective compressor.
0. Restrictive exhaust ducting.
Unit runs but does not pump water.
.   Hose kinked or plugged.
2.   Pump motor or float switch defective.
3.   Pump check valve plugged.
4.   Bad connection in pump circuit.
5.   Hose disconnected internally.
Unit pumps water automatically but not when purge switch 
is pushed.
.   Bad connection in purge switch circuit.
2.   Defective purge switch.
