CORRECT PLUG REMOVAL

Grasp IEC plug and pull straight out IMPORTANT: Damage to IEC receptacle or dehumidifier resulting from improper removal of the power cord is not covered by warranty. The IEC power cord is a wear item and is not covered by warranty.110489R (07-01674) F410, F411 2 Legend Brands, Inc. INTRODUCTION How LGR dehumidifiers work Dri-Eaz LGR (low-grain 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 that has accumulated on the evaporator coil back into water. The water collects in a tray and is pumped out through a hose. Onboard sensors continually monitor environmental conditions and system operations of the dehumidifier, including temperature and relative humidity, which can be viewed on the display panel. LGR dehumidifiers have better heat exchange and defrost abilities than regular refrigerant dehumidifiers, and are able to continue removing moisture in drier environments.

POSITIONING A DEHUMIDIFIER

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 though the drying chamber to a minimum. Place your dehumidifier against a wall, away from obstructions, and keep it away from anything that could block airflow into and out of the unit. Rugged rotomolded housing resists dents and scratches and is easy to maintain.

OPERATING YOUR DEHUMIDIFIER

Set unit upright NOTICE: If you transport an i-Series dehumidifier in a horizontal position, set it upright and let it stand for at least 30 minutes before you turn it on. When the machine is horizontal, the oil from the compressor flows into the refrigerant coils reducing the ability of the dehumidifier to function. Letting the unit stand upright for 30 minutes allows the oil to flow back into the compressor. Set up drain hose This unit automatically pumps out water on a regular basis. This dehumidifier is equipped with a quick- connect fitting for attachment to the provided 40 ft. (12 m) drain hose located in the side pocket. Unwrap the entire hose and place the open end in a sink, drain, bucket or outdoors – anywhere that water can drain out safely. If you use a bucket or other container for water collection, check it regularly to prevent overflows. NOTE: Uncoil and straighten the entire drain hose. Do not leave any of part 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. Plug in electrical cord The i-Series dehumidifier should be plugged into a GFCI-protected 115 volt outlet rated for at least 15 amps. Remove the cord from its storage pocket and uncoil it. Always plug the cord firmly into the unit first, and then plug the other end into a suitable outlet.110489R (07-01674) F410, F411 4 Legend Brands, Inc.
