INSTALLATION
• Use this appliance only for its intended purpose.
This product is not designed for preserving precision instruments, tableware or art works.

Indoor temperature and relative humidity affect dehumidification.
- Dehumidification is decreased if the temperature or relative humidity is low.
- The product does not operate unless the desired humidity level is lower than the current
humidity level.
This product operates at temperatures from 41 °F - 90 °F (5 °C - 32 °C).
- At temperatures of 32 °F (0 °C) or less, water freezes inside the product.
- At temperatures over 90°F (32 °C), the internal temperature of the product trips a protective
device which deactivates the product to avoid product damage.
When the dehumidifier is operating, the indoor temperature will rise.
- The dehumidifier does not have a cooling/heating function.
- Heat is generated during operation, so the room temperature may be increased by about 37 °F
(3 °C) depending on the usage conditions (indoor temperature, size of the room).
The compressor has a 3-minute delay before restarting.
- If the product is stopped and immediately restarted, to protect the compressor there is a
3-minute delay until the compressor restarts.
The product cannot be operated continuously for more than 23 hours.
After 23 hours of continuous operation, the compressor automatically shuts off for one hour to
prevent product damage. The compressor will restart after one hour. This Safety Standby function
is normal.
Install the product at least 11 13/16" (30 cm) from walls or other obstacles.
The product needs clearance for air intake and exhaust purposes.
There may be water in the drain water bucket before first use.
Water may remain in the drain water bucket from the product's outgoing inspection to check
operation. This is normal.
