READ COMPLETE SAFETY INSTRUCTIONS AND INSTALLATION INSTRUCTIONS BEFORE STARTING

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.
7. This 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.
8. Children should be supervised to ensure that they
do not play with the appliance.
9. If the supply cord is damaged, it must be replaced
by a special cord or assembly available from the
manufacturer or its service agent.
