Safety Instructions
WARNING
1. 120 Volts may cause serious injury from electric
shock. Disconnect electrical power before starting
installation or servicing. Leave power disconnected
until installation/service is completed.
2. Sharp edges may cause serious injury from cuts. Use
care when cutting plenum openings and handling
duct system.
3. Dropping may cause personal injury or equipment
damage. Handle with care and follow installation
instructions.
CAUTION
1. Read all instructions before beginning installation.
2. Improper installation may cause property damage or
injury. Installation, service, and maintenance must be
performed by a qualified service technician.
3. Do not use in pool applications. Pool chemicals can
damage the dehumidifier.
4. Do not use solvents or cleaners on or near the
circuit board. Chemicals can damage circuit board
components.
5. Wait 24 hours before running the unit if it was not
shipped or stored in the upright position
6. Do not use dehumidification to prevent window
condensation in the winter. During the winter the
dehumidifier does not run enough to effectively
prevent window moisture. The dehumidifier has a
40° dew point lower limit and the moisture level in a
home during the winter is usually below this value.
The window condensation is a result of the cold
outdoor air/window temperature. Ventilation is the
most effective and efficient means of dealing with
window condensation in the winter.
