• The DR65A3000 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.
1. Never operate a unit with a damaged power cord. If the power cord is damaged it must be
replaced by the manufacturer, its service agent, or similarly qualified person in order to
avoid a hazard.
2. The appliance is not intended for use by persons (including children) with reduced
physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they
have been given supervision or instruction concerning use of the appliance by a person
responsible for their safety. Children should be supervised to ensure that they do not play
with the appliance.

About the DR65A3000 Dehumidifier
The DR65A3000 ensures the home is maintained at proper humidity levels through its high performance and
efficiency.
Benefits
• Removes up to 65 pints (30.8 l) of water per day from the indoor
air.
• Built-in humidity control requires no additional wiring to an
external control. Just plug in and go! Choice of external control
options also available for centrally ducted control.
• Electrocoating reduces coil corrosion and helps prevent
refrigerant leaks
• Built-in transfromer circuit breaker.
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, you can run your cooling
equipment less because dehumidified air feels cooler.
Ideal humidity is defined by industry experts* as being between 4060% on an average annual basis.
When indoor humidity exceeds 60%,
the home is more susceptible to mold
and mildew growth. DR65A3000 safe-
guards against excessive humidity in
the home year-round.
*American Society of Heating, Refrigerating
and Air Conditioning Engineers (ASHRAE).

Cleaning
On an annual basis, perform the following maintenance requirement to ensure the dehumidifier runs at peak
efficiency.
DR65A3000 Dehumidification System 33-00297EFS—09 11
Unplug the dehumidifier before begin-
ning service. Remove magnetic access
panel to access the filter.
Remove filter and replace with new fil-
ter. Reinstall magnetic access panel.
When service is complete, initiate a
call for dehumidification and check
that the compressor and fan activate.
If your thermostat has maintenance
reminders, reset those. All thermostats
listed in this file have optional mainte-

Technical Description
DR65A3000 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 videos are available on the Resideo Pro YouTube channel playlist.

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.

À propos du déshumidificateur DR65A3000
Le DR65A3000 permet de maintenir les niveaux d’humidité adéquats dans toute la maison grâce à sa haute
performance et son efficacité.
Avantages
• Retire jusqu’à 30,8 litres (65 chopines) d’eau par jour de l’air
intérieur.
• La commande d’humidité intégrée ne nécessite aucun câblage
supplémentaire à un régulateur externe. Il suffit de brancher et
c’est parti! Choix d’options de régulateurs externes également
disponible pour une régulation centrale.
• L’électrodéposition réduit la corrosion sur le serpentin et aide à
prévenir les fuites de réfrigérant.
• Coupe-circuit du transformateur intégré.
Maintien d’une humidité idéale
Les points de rosée et d’humidité relative (HR) affectent la manière dont le corps ressent la chaleur. Des
niveaux d’humidité élevés causent une perception de chaleur accrue par rapport à la température réelle.
S’il est correctement entretenu, l’équipement de refroidissement peut être activé moins souvent car l’air
déshumidifié semble plus frais. L’humidité idéale est définie par les experts de l’industrie* comme se situant
entre 40 et 60 % sur une base annuelle moyenne.
Lorsque l’humidité intérieure
dépasse 60 %, l’habitation est plus
susceptible à la moisissure. L’unité
DR65A3000 protège de l’humidité
excessive tout au long de l’année.
