The TrueDRY™ DR90 is designed to be installed indoors in a space that is protected from rain and  
flooding.  
Install the unit with space to access the front panel for maintenance and service.  
Avoid directing the discharge air at people, or over the water in pool areas.  
If used near a pool or spa, be certain there is no chance the unit could fall into the water or be splashed,  
and that it is plugged into a ground fault interrupt (GFI) outlet.  
To ensure quiet operation, do not place the device directly on the structural supports of the home.  
A drain pan must be placed under the unit if installed above a living area or above an area where water  
leakage could cause damage.

About the TrueDRY™ DR90 Dehumidifier  
The Honeywell TrueDRY DR90 ensures the home is maintained at proper humidity levels through its high  
performance and efficiency.  
Benefits  
Removes up to 90 pints of water per day from the indoor air.  
Built-in fresh air supply  
Energy Star Rated  
Maintaining Ideal humidity  
Dew points and relative humidity (RH) affect the way your  
body senses heat. Higher humidity levels cause the air to feel  
much hotter than the actual temperature. When maintained  
properly, your cooling equipment may not run as much because  
dehumidified air feels cooler.  
Ideal humidity is defined by industry experts* as being between  
40-60% on an average annual basis.  
WHAT THE AIR FEELS LIKE  
HOW HOT THE HEAT-HUMIDITY COMBINATION MAKES IT FEEL.  
EXAMPLE: AIR AT 90ºF WITH 50% RH FEELS LIKE 96ºF TO THE HUMAN BODY!

Install to Fit Your Application  
Flex duct is recommended in connecting to the TrueDRY DR90 collars to reduce vibration noise.  
Duct sizing: Use minimum 10-in. diameter round for  
duct lengths up to 25 ft. Minimum 12-in. required for  
lengths longer than 25 ft. Duct branches from the  
main inlet/exhaust should be minimum 10-in. round  
for 2-3 branches, and 12-in. round or larger for 4  
branches or more.  
For the optional fresh air ventilator port, use 6-in.  
round, insulated duct for lengths up to 50 ft.  
Use 8-in. round duct for more than 50 ft. of if more  
than 100 CFM is required.  
Isolated Areas: Effective dehumidification may require  
ducting to isolated or stagnant air flow areas.  
Electrical requirements:  
115 VAC outlet. Ground fault  
interrupter (GFI) recommended.

from left to right in the photo) are:  
DHUM: Compressor and fan operation for  
dehumidification  
R: DR90 24V output  
FAN: Fan activation only for ventilation  
C: DR90 24V output  
External 24V devices can be powered from R and  
C terminals (20VA max.)

Checkout  
Apply power to TrueDRY DR90. Turn the humidity control to a low RH% level to initiate a dehumidification  
call. Confirm that the TrueDRY DR90 compressor and fan turn on. The furnace blower will also turn on to  
circulate air. This will take up to two minutes. Be sure to turn the control to the desired RH% or to Off when  
checkout is complete.  
Cleaning  
On an annual basis, maintenance is required to ensure TrueDRY runs at peak efficiency.  
Unplug TrueDRY DR90 before beginning  
service. Remove the magnetic filter door.  
Remove filter (50049537-005) and  
replace with new filter.

2
Remove the panels on each side of the  
TrueDRY DR90. Using a damp cloth,  
wipe excess dust and debris from  
blower, refrigerant coils, and compres-  
sor coils. Reattach cabinet panels when  
finished.  
Check the drain connection and drain  
line to ensure it is clear of debris and  
sludge. Ensure all hose connections  
are secure once maintenance of the  
drain lines is complete.

4
When service is complete, initiate  
a call for dehumidification and  
check that the compressor and fan  
activate. If using the VisionPRO IAQ or  
TrueIAQ controls, reset maintenance  
reminders.

Technical Description  
STRAINER/FILTER  
DRIER  
TrueDRY DR90 uses a refrigeration system similar to  
an air conditioner 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 causes 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 nearly constant  
pressure and temperature across the entire coil, from  
inlet to outlet.

Troubleshooting  
CAuTIOn: Servicing the TrueDRY DR90 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. Service should only be performed by a qualified service technician.  
Problem  
Recommended Troubleshooting steps  
No dehumidification. Neither  
fan nor compressor run and the  
ventilation timer is OFF.  
1. Unit unplugged or no power to outlet.  
2. Humidity control set too high or defective.  
3. Loose connection in internal or control wiring.  
4. Defective Compressor relay.  
5. Defective control transformer.  
6. Optional Condensate Pump Safety Switch open.  
No dehumidification. Compressor 1. Defective compressor run capacitor.  
does not run but fan runs when  
there is a call for dehumidification  
and the ventilation control is OFF.  
2. Bad connection in compressor circuit.  
3. Defective compressor overload.  
4. Defective compressor.  
5. Defrost thermostat open.  
6. Optional Condensate Pump Safety Switch open.  
Fan runs when there is a call  
for dehumidification and the  
ventilation control is OFF, but the  
compressor cycles on and off too  
frequently.  
1. Low ambient temperature and/or humidity causing unit to cycle  
through defrost mode.  
2. Defective compressor overload.  
3. Defective compressor.  
4. Defrost thermostat defective.  
5. Dirty air filter(s) or airflow restricted.  
6. Low refrigerant charge, causing defrost control to cycle.  
7. Bad connection in compressor circuit..

Troubleshooting (continued)  
Problem  
Recommended Troubleshooting steps  
Fan does not run with  
ventilation activated.  
Compressor runs briefly  
but cycles on & off with  
humidity control turned to  
ON.  
1. Loose connection in fan circuit.  
2. Obstruction prevents fan rotation.  
3. Defective fan.  
4. Defective fan relay.  
5. Defective fan capacitor.  
Evaporator coil frosted  
continuously, low de-  
humidifying capacity.  
1. Defrost thermostat loose or defective.  
2. Low refrigerant charge.  
3. Dirty air filter(s) or airflow restricted.  
Unit not providing  
ventilation.  
1. Check control wire connections (check connections at fresh air damper  
also).  
2. Defective fresh air damper.  
3. Dirty air intake. Clean outside intake hood.  
Unit removes some  
water, but not as much as  
expected.  
1. 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. Defective defrost thermostat.  
6. Low refrigerant charge.  
7. Air leak such as loose cover or ducting leaks.  
8. Defective compressor.  
9. Restrictive ducting.  
10. Optional Condensate Pump Safety Switch open.  
Unit Test to determine  
problem:  
1. Detach field control wiring connections from main unit.  
2. Connect the R and FAN contacts from the main unit together; only the  
impeller fan should run. Disconnect the wires.  
3. Connect the R and DHUM contacts from the main unit together; the  
compressor and impeller fan should run.  
4. If these tests work, the main unit is working properly. You should check  
the control panel and field control wiring for problems next.  
5. Remove the control panel from the mounting box and detach it from the  
field installed control wiring. Connect the blue, yellow, and green wires  
from the control panel directly to the corresponding colored pigtails on  
the main unit. Leave the violet, white, and red wires disconnected!  
6. Turn on the humidity control. The compressor and impeller fan should  
run.  
7. If these tests work, the problem is most likely in the field control wiring.  
Refrigerant Charging  
If the refrigerant charge is lost due to service or a leak, a new charge must be accurately weighed in. If any  
of the old charge is left in the system, it must be recovered before weighing in the new charge. Refer to the  
unit nameplate for the correct charge weight and refrigerant type.  
Compressor/Capacitor Replacement  
This compressor is equipped with a two terminal external overload and a run capacitor, but no start  
capacitor or relay.
