Dehumidifiers reduce humidity in enclosed structural environments by removing water vapor from the air. With proper use, 1200 can help dry carpet, carpet pad, floors, walls, building contents, and more. Using dehumidifiers can also help prevent secondary damage caused by high humidity. For best results, use 1200 with Dri-Eaz TurboDryer® air movers placed around the perimeter of the room to distribute heat energy and release moisture from wet surfaces into the air.

How the 1200 dehumidifier works

  • Dri-Eaz refrigerant dehumidifiers operate by pulling moist air in across a very cold evaporator core.
  • The moisture in the air condenses on the coil. In certain conditions, the machine operates in defrost mode, warming any frost accumulated on the evaporator coil back into the water.
  • The water collects in a tray and is pumped out through a hose.

IMPORTANT: Before moving the unit, make sure there’s no water in the pump. See how to use the PURGE function under “How to use the control pad” on page 2.


  • For best results, operate your dehumidifiers in an enclosed area, as this creates a drying chamber.
  • Close all doors and windows that open to the outside to maximize the unit’s water removal efficiency.
  • Also, keep traffic through the drying chamber to a minimum.
  • Place your 1200 dehumidifier against a wall, away from obstructions, and keep it away from anything that could block airflow into and out of the unit.

Managing temperature rise

  • DrizAir dehumidifiers warm the air as they remove moisture. Optimal drying temperatures range from 68−85°F (20−29°C).
  • The most accurate way to monitor temperature is with a thermo-hygrometer; however, you can use an indoor/outdoor thermometer to gauge temperature. Just make sure it is located in the center of the room away from the airflow of the dehumidifier.
  • If the temperature rises to unsafe levels (over 90°F/32°C) you can use the structure’s HVAC (heating air conditioning) system to bring the temperature down. Just set it to 80°F (27°C), and continue to operate the dehumidifier. For more information about creating an optimum drying environment, visit LegendBrandsRestoration.com.


Set unit upright

Always operate the dehumidifier in an upright position. If the unit has been stored or transported in a horizontal position, set it upright (vertical) for at least 30 minutes before operating it. When the unit is placed horizontal, oil from the compressor flows into the refrigerant coils reducing the ability of the dehumidifier to function.
Set up drain hose
The 1200 condensate pump connects to a plastic drainage hose that is wrapped around the air outlet located at the back of the unit. Unwrap the entire hose and place the unattached end in a sink, drain, bucket, or outside – anywhere that water can drain out safely. If you use a bucket or other receptacle for water collection, check it regularly to prevent spills.

NOTE: Uncoil and straighten the entire drain hose. Do not leave anypart of the hose coiled on the unit and do not place the end of the hose higher than 20 ft. (6 m) above the top of the unit. Also, check for kinks or obstructions that would restrict the flow of water. Failure to do so may cause a water backup in the pump resulting in leakage.

FRONTDri-Eaz F203-A-1200-Dehumidifier-Refrigerant-FIG-1Plug in electrical cord
Locate the electrical cord either on the top or back of the unit. The 1200 dehumidifier may be plugged into a 115-volt (15 amp) grounded outlet, which is standard in most homes.
If the unit experiences a loss of power, either from a power interruption or from thermal overload protection, let the unit rest for five minutes before restarting. Otherwise, it might shut off again.
Turn the unit on

  • Press the “on” button on the touchpad.

How to use the control panel
The Touchpad on DrizAir dehumidifiers has one display and four keys. The normal display messages.

  • GET SERVICE ERXXDri-Eaz F203-A-1200-Dehumidifier-Refrigerant-FIG-2

When the unit is first connected to AC power, the touchpad display will cycle continuously through three messages: DEHUMIDIFIER OFF, TOTAL HOURS, and JOB HOURS.
ON-OFF. Press the ON-OFF key to turn the unit on or off. When turning the machine on, usually the display reads CMPRSR DELAY and performs a numeral count down from a maximum of 60 seconds to 0. The compressor delay gives the machine time to warm up(when needed). If you don’t see a compressor delay countdown, the machine is ready to go. Once the unit completes the CMPRSR DELAY, the display reads DEHUMIDIFIER ON and continues to cycle between TOTAL HOURS, JOB HOURS, and DEHUMIDIFIER ON. Press the ON-OFF key again to turn the unit off. The display will read DEHUMIDIFIER OFF.
DISPLAY. Press the DISPLAY key to stop the display at DEHUMIDIFIER ON or OFF, TOTAL HOURS, or JOB HOURS as it cycles. Press DISPLAY again to restart the display cycle.

How to change the language display

CAUTION: While in the change-language mode, pressing other keys can change the programming of the machine. Do NOT press other keys you’re not instructed to press.
Use the DISPLAY key to change the display language. Follow these steps:

  1. Unplug the unit.
  2. While holding down the DISPLAY key, plug the unit in. The display reads ENGLISH.
  3. To change to FRANCAIS, DEUTSCH, or ESPANOL, press the DISPLAY key or the CLEAR key.
  4. When the desired language is shown in the display, unplug the unit, and the language is set.

CLEAR. Press the CLEAR key to reset the JOB HOURS

  1. As the display cycles between DEHUMIDIFIER ON, JOB HOURS, and TOTAL HOURS, press the DISPLAY key when JOB HOURS appears on the screen. That will make the display read JOB HOURS steadily.
  2. Then press the CLEAR key to re-set the numerals to 00000.
  3. Press DISPLAY again to re-start the display cycle. NOTE: the TOTAL HOURS reading cannot be reset.


PURGE: Press the PURGE key to empty water from the pump reservoir. During normal operation, the pump purges automatically every six minutes, or whenever the reservoir is full. The display will read PUMP PURGING with a numeral countdown. To purge the pump manually:

  1. Turn the power off using the OFF key, and let the unit sit plugged in for about 10 minutes. This allows water to drip from the coils and collects in the drip pan.
  2. Press PURGE to remove residual water.Dri-Eaz F203-A-1200-Dehumidifier-Refrigerant-FIG-3

Defrost mode
During normal operation, the temperature sensor detects frost forming on the coils, causing a defrost cycle to start. The display will read DEFROST ON. Dehumidification stops during the defrost cycle. When the unit completes the cycle, the display returns to DEHUMIDIFIER ON.

Error messages
If the 1200’s onboard diagnostics discover a problem, the unit will display “GET SERVICE,” followed by “ER” and a numeral from 01 to 09. If this message appears, first follow these steps:

  1. Unplug the unit and then plug it back in. This may re-set the electronics.
  2. If the error message reappears, try the solution (if one is listed) in the “Error Messages,” p. 4.
  3. If the error message still appears, please contact the Dri-Eaz Service Department at 888-867-3235.

At the end of the job
As with all dehumidifiers, once the drying job is completed, it is important to make sure the unit is completely purged of water before moving it. To ensure that all water has drained into the pump, turn the unit off, allow it to rest for 10 minutes, then press the PURGE button. (The unit must be plugged in for the purge to operate.) Once the purge cycle is complete, unplug the unit and remove it promptly from the job. Before transporting, be sure to remove the external drain hose, drain it carefully, and return it to the pocket provided on the front of the unit.
