INSTALLATION INSTRUCTIONS BEGIN ON PAGE 2

• 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.
• DR65 should be installed on a stationary base or sitting on the floor. It should not be mounted above other HVAC components such as the A-coil.

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 transformer and fuse.

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 40-60% on an average annual basis.

Capacity:

34 pints/day (60 ºF [15.6 ºC], 60 %RH)
47 pints/day (70 ºF [21.1 ºC], 60 %RH)
65 pints/day (80 ºF [26.7 ºC], 60 %RH)
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).

Setting the Controls

BUILT-IN HUMIDITY CONTROL: An intuitive ‘set and forget’ humidistat is built into the DR65A3000 to set the humidity level right on the device. Optional external control wiring is also available. If an external dehumidistat is used, the on-board dehumidification control must be set to the Off position.

Plumbing

Attach 3/4″ male NPT PCV drain noz- zle (use teflon tape if needed). Do not over-tighten.
Connect 1/2” drain tube to male con- nection drain outlet.
Secure drain tube to connector with hose clamp.
Run drain hose continuously downhill to an approved drain or condensate pump.
The drain line must include a water trap to prevent air from entering or exiting the dehumidifier.
NOTE: I t is important that the DR65 is leveled for drain line to work properly.

Terminal Description

CAUTION: Low voltage hazard.
Can cause equipment damage.
Disconnect HVAC equipment before beginning installation.

Two wiring terminal blocks are located on the exhaust end of the dehumidifier .The six terminals for the left hand terminal block are: FLOAT (2): External low- voltage water sensor or float switch

• DHUM: Compressor and fan operation for  dehumidification
• R: 24V hot (output)
• FAN: Fan activation only for ventilation
• C: 24V common (output)
  External 24V devices can be powered from R and C terminals (20VA max.)

NOTE: The outer screws on each terminal block secure the block to the chassis. They are not used for wiring.

The right hand terminal block in the above image is used only for interlocking a DR65A3000 with an equipment fan. These terminals are needed if:

• A: The dehumidifier is mounted on the HVAC ducting.
• B: The dehumidifier control cannot turn on the blower fan with a call for dehumidification (H6062, H8908).

The three terminals are:

• Gt: Wires to G at thermostat
• Rf: Wire to R at HVAC (furnace/air-handler)
• Gf: Wire to G at HVAC (furnace/air-handler)

Wiring

Wire the DR65A3000 according to the diagram that applies to your desired operation.Follow this diagram for ducted operation with the onboard dehumidistat.

Follow this diagram if using the H6062 Digital Humidity Controller.
NOTE: When H6062 control is used with a DR65 connected to HVAC ducting, make sure to wire the Rf, GT, and GF as shown in the diagram for the mechanical dehumidistat below.Follow this diagram if using an external manual dehumidistat . Dehumidifier with zoning
When a DR65 is used with a zoned system, wire Rf and Gf from DR65 to R and G at HVAC (furnace/air-han- dler). Wire Gt from DR65 to G on equipment terminals of zone panel. Set the dehumidity control to dehumid- ify independent of system fan (the DR65 will be turning on the fan).
Usually only one control is used for the dehumidifier in a zoned system. That could be an IAQ thermostat from a central zone or a stand alone dehumidity control. This control is wired to the R and DHUM on the DR65 as shown in any of the diagrams in this file.

Follow this diagram for ducted operation with external ventilation control.
NOTE: Dehumidity control circuit not shown in this diagram.

Follow this diagram if using DR65A3000 with either a Prestige or TH8321R1001 RedLINK VisionPro & EIM. IN THIS DIAGRAM, U1 CONTROLS THE DR65A FOR DEHUM AND U2 CONTROLS THE DR65A FOR VENTILATION.

Checkout

Apply power to DR65A3000. Turn the humidity control to a low RH% level to initiate a dehumidification call. Confirm that the DR65A3000 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. Turning the humidity control to Off will turn the DR65A3000 off.

Cleaning

On an annual basis, perform the following maintenance requirement to ensure the dehumidifier runs at peak efficiency.

1. Unplug the dehumidifier before begin- ning service. Remove magnetic access panel to access the filter.
2. Remove filter and replace with new fil- ter. Reinstall magnetic access panel.
3. 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 your thermostat has maintenance reminders, reset those. All thermostats listed in this file have optional mainte- nance reminders.

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

Troubleshooting videos are available on the Resideo Pro YouTube channel playlist.

CAUTION: Servicing the DR65A3000 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.
