1. Intended Application

SAKURA Dry-Boy is intended for installation in crawl spaces 
or basements that experience short or long-term high humidity 
conditions; however, the attractively designed unit can be placed in 
almost any residential setting where dehumidification is desired. Use 
in non-residential applications and pool areas will void warranty.

SAKURA Dry-Boy is designed to operate in temperatures 
between 56° and 95°F. Temperatures outside of these ranges may 
affect dehumidifier performance.

In order to efficiently control the humidity levels, the area in which the 
dehumidifier is to be placed must be free of water intrusion or excessive 
fresh (outside) air infiltration. Before installing SAKURA Dry-Boy
water intrusion and air infiltration problems should be addressed.
