Caution
DO NOT INSTALL THE COOLMASTER DEVICE IN THE FOLLOWING LOCATIONS:
Where a mineral oil mist or oil spray or vapor is produced, for example, in a kitchen. Plastic parts may deteriorate and
fall off or result in water leakage.
Where corrosive gas, such as sulfurous acid gas, is produced.
Near machinery emitting electromagnetic waves. Electromagnetic waves may disturb the operation of the CoolMaster
device and cause the unit to malfunction.
Where ammable gas may leak, where there is carbon ber or ignitable dust suspensions in the air, or where volatile
ammable such as thinner or gasoline are handle Operating the CoolMaster device in such conditions can cause a re.
High temperature area or directly amed point. Heating and/or re can occur.
Moist area, where there is exposure to water. If water enters the inside of the CoolMaster device, it may cause electric
shock and electrical components may fail.
