DV090/DV120 Dehumidification System 33-00547ES—01

About the DV090/DV120 Dehumidifier

Benefits

• Removes up to 90 (DV090) or 120 (DV120) pints of water per day from the indoor air
• Built-in fresh air supply
• Built-in transformer 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, your cooling equipment may not run as much because dehumidified air feels cooler. Ideal humidity is defined by American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) 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!

DV090 Specifications

Install DV090 according to National Electric Codes.

Install to Fit Your Application

Flex duct is recommended in connecting to the DV090/DV120 collars to reduce vibration noise.

Duct Sizing: Use minimum 10” diameter round for duct lengths up to 25’ Minimum 12” required for lengths longer than 25’ Duct branches from the main inlet/exhaust should be minimum 10” round for 2-3 branches, and 12” round or larger for 4 branches or more.
For the optional fresh air ventilator port, use 6” round, insulated duct for lengths up to 50’ Use 8” round duct for more than 50’ 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.

Dedicated Return to Main Supply

Ideal when…

• Access to dedicated central return for dehumidifier is available.
• Combined with A/C operation, requires backdraft damper on the exhaust port to minimize backdraft when dehumidifier is not on but A/C is.
• (optional) Duct humidifier supply with 20% open gravity damper to provide dry air to a specific area

Main Return to Main Supply

Ideal when…

• Running dehumidifier when not running A/C.
• Requires damper on the exhaust port to minimize backdraft when DV090/DV120 is not on but A/C is.
• Access to a dedicated central return is not possible.
• System fan should run with dehumidifier for best results.

Main Return to Main Return

Ideal when…

• Running DV090/DV120 with A/C operation.
• Minimizing discharge air temperature (DAT) increase is preferred.
• Access to a dedicated return is not possible.

Dedicated Return to Dedicated Supply

Ideal when…

The dehumidifier will not be ducted to a forced air HVAC system.

Plumbing

Attach 3/4” male NPT drain nozzle.
Connect 1/2” drain tube to male connection 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.

Terminal Description

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

NOTE: The outer screws on the terminal block secure the block to the chassis. They are not used for wiring.
A wiring terminal block is located on the side panel of the dehumidifier unit.
The six terminals for the terminal block (reading from left to right in the photo) are:

• FLOAT: External low voltage float switch or water sensor (two terminals). Use normally closed switch.
• DHUM: Compressor and fan operation for dehumidification
• R: DV090/DV120 24V output
• FAN: Fan activation only for ventilation
• C: DV090/DV120 24V output External 24V devices can be powered from R and C terminals (20VA max.)

Wiring

Wire the DV090/DV120 according to the diagram that applies to your desired operation.

Checkout
Apply power to DV090/DV120. Turn the humidity control to a low RH% level to initiate a dehumidification call. Confirm that the DV090/DV120 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.
If using for ventilation, initiate a call for ventilation. Confirm that the DV090/DV120 fan turned on, but that the compressor remained off.

Cleaning

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

1. Unplug DV090/DV120 before beginning service. Remove the magnetic filter door.
2. Remove filter and replace with new filter.
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.

Technical Description
DV090/DV120 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 DV090/DV120 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.
